CLion 2022.2 Help

Docker plugin integration

Docker is a tool for deploying and running executables in isolated and reproducible environments. This may be useful, for example, to test code in an environment identical to production. CLion provides Docker support using the Docker plugin. The plugin is bundled and enabled by default .

Enable Docker support

  1. Install and run Docker.

    For more information, see the Docker documentation.

  2. Configure the Docker daemon connection settings:

    • Press Ctrl+Alt+S to open the IDE settings and select Build, Execution, Deployment | Docker.

    • Click The Add button to add a Docker configuration and specify how to connect to the Docker daemon.

      The connection settings depend on your Docker version and operating system. For more information, see Docker configuration settings.

      The Connection successful message should appear at the bottom of the dialog.

      The Docker connection settings
  3. Connect to the Docker daemon.

    The configured Docker connection should appear in the Services tool window (View | Tool Windows | Services or Alt+8). Select the Docker node Docker node and clickThe Connect button, or select Connect from the context menu.

    The Docker tool window, connected to Docker

    To edit the Docker connection settings, select the Docker node and click The Edit Configuration button on the toolbar, or select Edit Configuration from the context menu.

In the Services tool window (View | Tool Windows | Services or Alt+8), you can pull and push images, create and run containers, manage Docker Compose services, and so on. As with other tool windows, you can start typing the name of an image or container to highlight the matching items.

The Docker tool window, text search

Managing images

Docker images are executable packages for running containers. Depending on your development needs, you can use Docker for the following:

Images are distributed via the Docker registry. Docker Hub is the default public registry with all of the most common images: various Linux flavors, database management systems, web servers, runtime environments, and so on. There are other public and private Docker registries, and you can also deploy your own registry server.

Configure a Docker registry

  1. Press Ctrl+Alt+S to open the IDE settings and select Build, Execution, Deployment | Docker | Registry.

  2. Click The Add button to add a Docker registry configuration and specify how to connect to the registry. If you specify the credentials, CLion will automatically check the connection to the registry. The Connection successful message should appear at the bottom of the dialog.

    The Docker Registry dialog

For more information, seeDocker Registry.

Pull an image from a Docker registry

  1. In the Services tool window, select the Images node.

  2. Under Images Console, type the name of the image to pull . Use completion Ctrl+Space to select from the available suggestions of official images. Press Ctrl+Space again to see relevant images from all users.

    The Pull Image dialog
  3. Press Ctrl+Enter to run docker pull.

  4. Specify the image as in the Docker CLI, for example: ubuntu:20.04.

Build an image from a Dockerfile

When you are editing a Dockerfile, CLion provides completion for images from the configured registries.

  1. Open the Dockerfile from which you want to build the image.

  2. Click Run on Docker in the gutter and select to build the image.

    The Build Image on Docker popup

CLion creates a Dockerfile run configuration that runs the docker build command.

Push an image to a Docker registry

  1. In the Services tool window, select the image that you want to upload and click The Push Image button or select Push Image from the context menu.

    The Push Image context menu item
  2. Select the Docker registry and specify the repository and tag (name and version of the image, for example, my-app:v2).

    The Push Image dialog
  3. Click OK to run the docker push command.

Copy image to another Docker daemon

If you have several Docker daemon connections, you can copy an image from one Docker daemon to another.

  1. In the Services tool window, select the image that you want to copy and click The Copy Docker Image button or select Copy Docker Image from the context menu.

  2. In the Copy Docker Image dialog, select the Docker daemon to which you want to copy the image and click Copy.

This first runs the docker save command to save the image from the current Docker daemon as a file, and then the docker load command to load the image from the file on the target Docker daemon.

CLion stores images that you pull or build locally and lists them in the Services tool window under the Images node. When you select an image, you can view its name, ID, date of last changes, size, tags, and any containers using this image, if any. You can also create a new container from the selected image, push the image, or view the layers used by the image. Click the More button to see more actions: copy the image ID to the clipboard, run the docker image inspect command, or show labels applied to the image.

Docker image properties

Images with no tags <none>:<none> can be one of the following:

  • Intermediate images that serve as layers for other images and do not take up any space

  • Dangling images that remain when you rebuild an image based on a newer version of another image. You should regularly prune dangling images to preserve disk space.

To hide untagged images from the list, click The Filter menu on the Docker toolbar, and remove the checkmark from Untagged Images.

To delete one or several images, select them in the list and clickThe Delete Image button.

Running containers

Docker containers are runtime instances of the corresponding images. CLion uses run configurations to execute the commands that build Docker images and run containers. There are three types of Docker run configurations:

Run a container from an existing image

  1. In the Services tool window, select an image and click The Create container button or select Create Container from the context menu.

  2. In the Create Container popup, click Create....

  3. In the Create Docker Configuration dialog that opens, you can provide a unique name for the configuration and specify a name for the container. If you leave the Container name field empty, Docker will give it a random unique name.

  4. When you are done, click Run to launch the new configuration.

Run a container from a Dockerfile

  1. Open the Dockerfile from which you want to run the container.

  2. Click Run on Docker in the gutter and select to run the container from this Dockerfile.

This creates and starts a run configuration with default settings, which builds an image based on the Dockerfile and then runs a container based on this image.

To create a run configuration with custom settings, click Run on Docker in the gutter and select New Run Configuration.... You can specify a custom tag for the built image, as well as a name for the container, and a context folder from which to read the Dockerfile. The context folder can be useful, for example, if you have some artifacts outside of the scope of your Dockerfile, which you would like to add to the file system of the image.

Docker run configurations

Create a Docker run configuration

  1. From the main menu, select Run | Edit Configurations.

  2. In the Run/Debug Configurations dialog, clickThe Add New Configuration button, point to Docker, and then click the desired type of run configuration.

Use this type of configuration to run a Docker container from a locally existing image that you either pulled or built previously.

Docker uses the docker run command with the following syntax:

docker run [OPTIONS] IMAGE [COMMAND] [ARG...]

You can set all the arguments for this command using the options of the Docker Image run configuration.

By default, the Docker Image configuration has the following options:

Name

Specify a name for the run configuration to quickly identify it among others when editing or running.

Allow parallel run

Allow running multiple instances of this run configuration in parallel.

By default, it is disabled, and when you start this configuration while another instance is still running, CLion suggests stopping the running instance and starting another one. This is helpful when a run configuration consumes a lot of resources and there is no good reason to run multiple instances.

Store as project file

Save the file with the run configuration settings to share it with other team members. The default location is .idea/runConfigurations. However, if you do not want to share the .idea directory, you can save the configuration to any other directory within the project.

By default, it is disabled, and CLion stores run configuration settings in .idea/workspace.xml.

Server

Select the Docker daemon connection to use for the run configuration.

Image ID or name

Specify the identifier or the name of the Docker image from which to create the container.

Container name

Specify an optional name for the container. If empty, Docker will generate a random name for the container.

This is similar to using the --name option with the docker run command.

Before launch

Specify a list of tasks to perform before starting the run configuration. For example, run another configuration, build the necessary artifacts, run some external tool or a web browser, and so on.

Click the Add button or press Alt+Insert to add one of the available tasks.

Move tasks in the list using the Up button and the Down button to change the order in which to perform the tasks. Select a task and click the Edit button to edit the task. Click the Remove button to remove the selected task from the list.

Show this page

Show the run configuration settings before actually starting it.

Activate tool window

Depending on the type of configuration, open the Run, Debug, or Services tool window when you start this run configuration. If this option is disabled, you can open the tool window manually:

  • View | Tool Windows | Run or Alt+4

  • View | Tool Windows | Debug or Alt+5

  • View | Tool Windows | Services or Alt+8

Use the Modify options menu to add advanced options to the run configuration:

Randomly publish all exposed ports

Publish all exposed container ports to random free ports on the host.

This is similar to using the -P or --publish-all option on the command line.

Bind ports

Map specific container ports to specific ports on the host.

This is similar to using the -p or --publish option on the command line.

Click Browse in the Bind ports field and specify which ports on the host should be mapped to which ports in the container. You can also provide a specific host IP from which the port should be accessible (for example, you can set it to 127.0.0.1 to make it accessible only locally, or set it to 0.0.0.0 to open it for all computers in your network).

Lets say you already have PostgreSQL running on the host port 5432, and you want to run another instance of PostgreSQL in a container and access it from the host via port 5433. Binding the host port 5433 to port 5432 in the container is similar to setting the following command-line option:

-p 5433:5432

You can set this option explicitly in the Run options field instead of configuring the Bind ports field.

Entrypoint

Override the default ENTRYPOINT of the image.

This is similar to using the --entrypoint option on the command line.

Command

Override the default CMD of the image.

This is similar to adding the command as an argument for docker run.

Bind mounts

Mount files and directories on the host to a specific location in the container.

This is similar to using the -v or --volume option on the command line.

Click Browse in the Bind mounts field and specify the host directory and the corresponding path in the container where it should be mounted. Select Read only if you want to disable writing to the container volume.

For example, you can mount a local PostgreSQL directory on the host (/Users/Shared/pg-data) to some directory inside the container (/var/lib/pgsql/data). Mounting volumes in this manner is similar to setting the following command-line option:

-v /Users/Shared/pg-data:/var/lib/pgsql/data

You can set this option explicitly in the Run options field instead of configuring the Bind mounts field.

Environment variables

Specify environment variables. There are environment variables associated with the base image that you are using as defined by the ENV instruction in the Dockerfile. There are also environment variables that Docker sets automatically for each new container. Use this field to override any of the variables or specify additional ones.

This is similar to using the -e or --env option on the command line.

Click Browse in the Environment variables field to add names and values for variables.

For example, if you want to connect to PostgreSQL with a specific username by default (instead of the operating system name of the user running the application), you can set the PGUSER variable to the necessary value. This is similar to setting the following command-line option:

--env PGUSER=%env-var-value

You can set this option explicitly in the Run options field instead of configuring the Environment variables field.

Run options

Set any other supported docker run options.

For example, to connect the container to the my-net network and set the my-app alias for it, specify the following:

--network my-net --network-alias my-app

Attach to container

Attach to the container's standard input, output, and error streams.

This is similar to using the -a or --attach option on the command line.

Show command preview

Preview the resulting command that will be used to execute the run configuration.

Use this type of configuration to build an image from a Dockerfile and then derive a container from this image.

Docker uses the docker build command to build an image from a Dockerfile, and then the docker run command to start a container from it.

By default, the Dockerfile configuration has the following options:

Name

Specify a name for the run configuration to quickly identify it among others when editing or running.

Allow parallel run

Allow running multiple instances of this run configuration in parallel.

By default, it is disabled, and when you start this configuration while another instance is still running, CLion suggests stopping the running instance and starting another one. This is helpful when a run configuration consumes a lot of resources and there is no good reason to run multiple instances.

Store as project file

Save the file with the run configuration settings to share it with other team members. The default location is .idea/runConfigurations. However, if you do not want to share the .idea directory, you can save the configuration to any other directory within the project.

By default, it is disabled, and CLion stores run configuration settings in .idea/workspace.xml.

Server

Select the Docker daemon connection to use for the run configuration.

Dockerfile

Specify the name and location of the Dockerfile used to build the image.

Image tag

Specify an optional name and tag for the built image.

This can be helpful for referring to the image in the future. If you leave the field blank, the image will have only a random unique identifier.

Container name

Specify an optional name for the container. If empty, Docker will generate a random name for the container.

This is similar to using the --name option with the docker run command.

Before launch

Specify a list of tasks to perform before starting the run configuration. For example, run another configuration, build the necessary artifacts, run some external tool or a web browser, and so on.

Click the Add button or press Alt+Insert to add one of the available tasks.

Move tasks in the list using the Up button and the Down button to change the order in which to perform the tasks. Select a task and click the Edit button to edit the task. Click the Remove button to remove the selected task from the list.

Activate tool window

Depending on the type of configuration, open the Run, Debug, or Services tool window when you start this run configuration. If this option is disabled, you can open the tool window manually:

  • View | Tool Windows | Run or Alt+4

  • View | Tool Windows | Debug or Alt+5

  • View | Tool Windows | Services or Alt+8

Use the Modify options menu to add advanced options to the run configuration:

Context folder

Specify a local directory that the daemon will use during the build process. All host paths in the Dockerfile will be processed relative to this directory. By default, if you leave it blank, Docker uses the same directory where the Dockerfile is located.

Build args

Specify values for build-time variable that can be accessed like regular environment variables during the build process but do not persist in the intermediate or final images.

This is similar to using the --build-args option with the docker build command.

These variables must be defined in the Dockerfile with the ARG instruction. For example, you can define a variable for the version of the base image that you are going to use:

ARG PGTAG=latest FROM postgres:$PGTAG

The PGTAG variable in this case will default to latest and the Dockerfile will produce an image with the latest available version of PostgreSQL, unless you redefine it as a build-time argument. If you set, PGTAG=9, Docker will pull postgres:9 instead, which will run a container with PostgreSQL version 9.

Redefining the PGTAG argument is similar to setting the following command-line option:

--build-arg PGTAG=9

Build options

Set any other supported docker build options.

For example, you can specify metadata for the built image with the --label option.

Enable BuildKit (experimental)

Use the BuildKit backend when building the images.

This is similar to setting the DOCKER_BUILDKIT=1 environment variable when invoking the docker build command.

Randomly publish all exposed ports

Publish all exposed container ports to random free ports on the host.

This is similar to using the -P or --publish-all option on the command line.

Bind ports

Map specific container ports to specific ports on the host.

This is similar to using the -p or --publish option on the command line.

Click Browse in the Bind ports field and specify which ports on the host should be mapped to which ports in the container. You can also provide a specific host IP from which the port should be accessible (for example, you can set it to 127.0.0.1 to make it accessible only locally, or set it to 0.0.0.0 to open it for all computers in your network).

Lets say you already have PostgreSQL running on the host port 5432, and you want to run another instance of PostgreSQL in a container and access it from the host via port 5433. Binding the host port 5433 to port 5432 in the container is similar to setting the following command-line option:

-p 5433:5432

You can set this option explicitly in the Run options field instead of configuring the Bind ports field.

Entrypoint

Override the default ENTRYPOINT of the image.

This is similar to using the --entrypoint option on the command line.

Command

Override the default CMD of the image.

This is similar to adding the command as an argument for docker run.

Bind mounts

Mount files and directories on the host to a specific location in the container.

This is similar to using the -v or --volume option on the command line.

Click Browse in the Bind mounts field and specify the host directory and the corresponding path in the container where it should be mounted. Select Read only if you want to disable writing to the container volume.

For example, you can mount a local PostgreSQL directory on the host (/Users/Shared/pg-data) to some directory inside the container (/var/lib/pgsql/data). Mounting volumes in this manner is similar to setting the following command-line option:

-v /Users/Shared/pg-data:/var/lib/pgsql/data

Attach to the container's standard input, output, and error streams.

This is similar to using the -a or --attach option on the command line.

Show command preview

Preview the resulting command that will be used to execute the run configuration.

Use this type of configuration to run multi-container Docker applications.

Docker uses the docker-compose command to define, configure, and run multi-container applications. The main command that builds, creates, starts, and attaches to containers is docker-compose up.

By default, the Docker-compose configuration has the following options:

Name

Specify a name for the run configuration to quickly identify it among others when editing or running.

Allow parallel run

Allow running multiple instances of this run configuration in parallel.

By default, it is disabled, and when you start this configuration while another instance is still running, CLion suggests stopping the running instance and starting another one. This is helpful when a run configuration consumes a lot of resources and there is no good reason to run multiple instances.

Store as project file

Save the file with the run configuration settings to share it with other team members. The default location is .idea/runConfigurations. However, if you do not want to share the .idea directory, you can save the configuration to any other directory within the project.

By default, it is disabled, and CLion stores run configuration settings in .idea/workspace.xml.

Server

Select the Docker daemon connection to use for the run configuration.

Compose files

Specify the compose files that define the necessary services. Docker Compose builds the configuration in the specified order, so any subsequent files override and add to the fields of the same service in previous files.

This is similar to using the -f option with the docker-compose command.

Services

Specify the services to build, create, and start.

Click the Browse icon (The Browse icon) to select services that are listed in the YML file.

docker-compose browse icon

Before launch

Specify a list of tasks to perform before starting the run configuration. For example, run another configuration, build the necessary artifacts, run some external tool or a web browser, and so on.

Click the Add button or press Alt+Insert to add one of the available tasks.

Move tasks in the list using the Up button and the Down button to change the order in which to perform the tasks. Select a task and click the Edit button to edit the task. Click the Remove button to remove the selected task from the list.

  • View | Tool Windows | Run or Alt+4

  • View | Tool Windows | Debug or Alt+5

  • View | Tool Windows | Services or Alt+8

Use the Modify options menu to add advanced options to the run configuration:

Project name

Specify an alternate project name for Docker Compose. By default, it is the name of the current directory.

This is similar to using the -p option with the docker-compose command.

Environment variables

Specify the Docker Compose environment variables. These are used only by the Docker Compose process. They are not passed on to any of the containers.

Environment variables file

Specify the path to a custom environment file that defines the Docker Compose environment variables.

By default, Docker Compose looks for a file named .env in the project directory.

This is similar to using the --env-file option with the docker-compose command.

Enable BuildKit (experimental)

Use the BuildKit backend when building the images.

This is similar to setting the DOCKER_BUILDKIT=1 environment variable when invoking the docker build command.

Remove volumes on `down`

When stopping and removing containers, also delete named volumes declared in the Docker Compose file and anonymous volumes attached to containers.

This is similar to using the -v or --volumes option with the docker-compose down command.

Enable compatibility mode

Convert v3 service definitions into v2 compatible parameters.

This is similar to using the --compatibility option with the docker-compose command.

Remove images on `down`

Configure which images should be removed when stopping and removing containers. You can choose to remove all images used by any service or only images that don't have a custom tag set in the image field.

This is similar to using the --rmi option with the docker-compose down command.

Timeout

Set a timeout in seconds to forcefully terminate containers that won't shutdown gracefully.

Docker usually tries to gracefully terminate any container with SIGTERM, but it might end up running indefinitely. Set a timeout after which Docker should send SIGKILL to force the shutdown.

This is similar to using the -t or --timeout option with the docker-compose up command.

Exit code

Return the exit code of the selected service container.

Whenever a container in the selected service stops, return its exit code and stop all other containers in the service.

This is similar to using the --exit-code-from option with the docker-compose up command.

Override scale

Set the number of containers to start for each service.

This option overrides the scale parameter in the Docker Compose file, if it's present.

This is similar to using the --scale option with the docker-compose up command.

Recreate dependencies

Recreate dependent containers when starting a service.

This is similar to using the --always-recreate-deps option with the docker-compose up command.

Recreate anonymous volumes

Recreate anonymous volumes instead of retrieving data from the previous containers.

This is similar to using the -V or --renew-anon-volumes option with the docker-compose up command.

Remove orphans

Remove containers for services not defined in the Docker Compose file.

This is similar to using the --remove-orphans option with the docker-compose up command.

Start

Configure which services to start:

  • Selected and dependencies: By default, Docker Compose starts all of the specified services and linked services.

  • Start: none: Don't start any services after creating them. This is similar to using the --no-start option with the docker-compose up command.

  • Start: selected services: Don't start any of the linked services. This is similar to using the --no-deps option with the docker-compose up command.

Attach to

Configure for which containers to show output streams:

  • Selected services: By default, Docker Compose attaches to all started containers of the specified services.

  • Attach to: none: Don't attach to any containers. This is similar to using the -d or --detach option with the docker-compose up command.

  • Attach to: selected and dependencies: Attach to containers of the specified services and linked services. This is similar to using the --attach-dependencies option with the docker-compose up command.

Recreate containers

Configure which containers to stop and replace by new ones:

  • Changed configuration: By default, Docker Compose recreates containers only if the corresponding configuration or image has changed.

  • Recreate containers: all: Recreate all containers in the services, even if the corresponding configuration or image hasn't changed. This is similar to using the --force-recreate option with the docker-compose up command.

  • Recreate containers: none: Don't recreate any containers in the services, even if the corresponding configuration has changed. This is similar to using the --no-recreate option with the docker-compose up command.

Build

Configure which images to build before starting containers:

  • Only missing images: By default, Docker Compose only builds images that are not available and uses previously built ones when possible.

  • : Don't build any images. Always use previously built images or throw an error if some image is not available. This is similar to using the --no-build option with the docker-compose up command.

  • Build: always: Always build images before starting containers. This is similar to using the --build option with the docker-compose up command.

Stop Containers

Configure how to stop containers in a service. By default, Docker Compose doesn't stop other containers in a service. You have to stop them manually.

However, you can choose to stop all containers if any container in a service stops. This is similar to using the --abort-on-container-exit option with the docker-compose up command.

Interacting with containers

Created containers are listed in the Services tool window. By default, the Services tool window displays all containers, including those that are not running. To hide stopped containers from the list, click The Filter button in the toolbar, select Docker, and then click Stopped Containers to remove the checkbox.

When you select a container, you can view the Build Log tab that shows the deployment log produced by the corresponding Docker run configuration while creating and starting the container.

The Build Log tab of a container selected in the Services tool window

The Dashboard tab provides important information about the container. Besides its name and hash ID, it also lists the environment variables, ports, and volume bindings. You can add, edit, and remove the environment variables, ports, and volume bindings. However, these changes require you to recreate the container and do not change in the Docker run configuration that is used to create this container. This means that the changes will not persist when you run the configuration next time.

The Dashboard tab of a container selected in the Services tool window

For more information, see Container dashboard.

Execute a command inside a running container

  1. In the Services tool window, right-click the container name and then click Exec.

  2. In the Run Command in Container popup, click Create and Run... to create and execute a new command.

    Alternatively, you can select one of the commands that you ran previously.

  3. In the Exec dialog, type the command and click OK. For example:

    ls /tmp

    List the contents of the /tmp directory

    mkdir /tmp/my-new-dir

    Create the my-new-dir directory inside the /tmp directory

    /bin/bash

    Start a bash session

For more information, see the docker exec command reference.

View detailed information about a running container

  • In the Services tool window, right-click the container name and then click Inspect.

    The output is rendered as a JSON object on the Inspection tab.

For more information, see the docker inspect command reference.

View processes running in a container

  • In the Services tool window, right-click the container name and then click Show Processes.

    The output is rendered as a JSON array on the Processes tab.

For more information, see the docker top command reference.

Attach a console to the container output

  • In the Services tool window, right-click the container and then click Attach.

    The console is attached to the output of the ENTRYPOINT process running inside a container, and is rendered on the Attached Console tab.

For more information, see the docker attach command reference.

Docker Compose

Docker Compose is used to run multi-container applications. For example, you can run a web server, a backend database, and your application code as separate services. Each service can be scaled by adding more containers if necessary. This enables you to perform efficient development and testing in a dynamic environment, similar to production.

Run a multi-container Docker application

  1. Define necessary services in one or several Docker Compose files.

  2. From the main menu, select Run | Edit Configurations.

  3. ClickThe Add icon, point to Docker and then click Docker-compose.

  4. Specify the Docker Compose files that define services which you want to run in containers. If necessary, you can restrict the services that this configuration will start, specify environment variables, and force building of images before starting corresponding containers (that is, add the --build option for the docker-compose up command).

    For more information about the available options, seeDocker-compose.

  5. Click OK to save the Docker Compose run configuration, select it in the main toolbar and click the Run button or press Shift+F10 to start the configuration.

When Docker Compose runs your multi-container application, you can use the Services tool window to control specific services and interact with containers. The containers are listed under the dedicated Compose nodes, not under the Containers node (which is only for standalone containers).

Scale a service

  1. In the Services tool window, select the service you want to scale and click The Scale button or select Scale from the context menu.

    The Scale context menu item
  2. Specify how many containers you want for this service and click OK.

Stop a running service

  • In the Services tool window, select the service and click The Stop button or select Stop from the context menu.

    The Stop context menu item

Stop all running services

  • In the Services tool window, select the Compose node and click The Stop button or select Stop from the context menu.

Bring your application down

  • In the Services tool window, select the Compose node and click The Down button or select Down from the context menu.

This stops and removes containers along with all related networks, volumes, and images.

Open the Docker Compose file that was used to run the application

  • In the Services tool window, right-click the Compose node or a nested service node and then click Jump to Source in the context menu or pressF4.

The Docker-compose run configuration will identify environment files with the .env suffix if they are located in the same directory as the Docker Compose file.

Troubleshooting

If you encounter one of the following problems, try the corresponding suggested solution.

Unable to connect to Docker

Make sure that:

If you are using Docker for Windows, enable the Expose daemon on tcp://localhost:2375 without TLS option in the General section of your Docker settings.

If you are using Docker Toolbox, make sure that Docker Machine is running and its executable is specified correctly in the Settings/Preferences dialog Ctrl+Alt+S under Build, Execution, Deployment | Docker | Tools.

Unable to use Docker Compose

Make sure that the Docker Compose executable is specified correctly in the Settings/Preferences dialog Ctrl+Alt+S under Build, Execution, Deployment | Docker | Tools.

Unable to use port bindings

Make sure that the corresponding container ports are exposed. Use the EXPOSE command in your Dockerfile.

Unable to associate existing Dockerfiles or Docker Compose files with relevant types

When you create new Dockerfiles or Docker compose files, CLion automatically identifies their type. If a file type is not evident from its name, you will be prompted to select the file type manually. To associate an existing file with the correct type, right-click it in the Project tool window and select Associate with File Type from the context menu.

If the Associate with File Type actions is disabled, this probably means that the filename is registered as a pattern for current file type. For example, if you have a Dockerfile with a custom name that is recognized as a text file, you cannot associate it with the Dockerfile type. To remove the file type pattern, do the following:

  1. Press Ctrl+Alt+S to open the IDE settings and select Editor | File Types.

  2. Select the relevant file type (in this case: Text) and remove the pattern with the name of the file.

  3. Click OK to apply the changes.

Now you should be able to set the correct file type using Associate with File Type in the context menu.
