Click this list to select one of the projects, opened in the same PyCharm window, where this run/debug configuration should be used. If there is only one open project, this field is not displayed.
This field shows the list of environment variables. If the list contains several variables, they are delimited with semicolons. To fill in the list, click the browse button, or press Shift+Enter and specify the desired set of environment variables in the Environment Variables dialog. To create a new variable, click, and type the desired name and value.
You might want to populate the list with the variables stored as a series of records in a text file, for example:
Variable1 = Value1
Variable2 = Value2
Just copy the list of variables from the text file and click Paste () in the Environmental Variables dialog. The variables will be added to the table. Click Ok to complete the task. At any time, you can select all variables in the Environment Variables dialog, click Copy , and paste them into a text file.
In this field, specify the string to be passed to the interpreter. If necessary, click, and type the string in the editor.

When a default run/debug configuration is created by the keyboard shortcutCtrl+Shift+F10, or by choosing Run from the context menu of a script, the working directory is the one that contains the executable script. This directory may differ from the project directory.
When this field is left blank, the bin directory of the PyCharm installation will be used.

Docker container settings
Click to open the dialog and specify the following settings:
Disable networking: select this checkbox to have the networking disabled. This corresponds to --net="none", which means that inside a container the external network resources are not available.
Network mode: corresponds to the other values of the option --net.
bridge is the default value. An IP address will be allocated for container on the bridge’s network and traffic will be routed though this bridge to the container. Containers can communicate via their IP addresses by default. To communicate by name, they must be linked.
host: use the host's network stack inside the container.
container:<name|id>: use the network stack of another container, specified via its name or id.
Links: Use this section to link the container to be created with the other containers. This is applicable to Network mode = bridge and corresponds to the --link option.
Publish all ports: Expose all container ports to the host. This corresponds to the option --publish-all.
Port bindings: Specify the list of port bindings. Similar to using the -p option with docker run.
Extra hosts: This corresponds to the --add-host option. Refer to the page Managing /etc/hosts for details.
Volume bindings: Use this field to specify the bindings between the special folders-volumes and the folders of the computer, where the Docker daemon runs. This corresponds to the -v option. See Managing data in containers for details.
Environment variables: Use this field to specify the list of environment variables and their values. This corresponds to the -e option. Refer to the page ENV (environment variables) for details.

Share through VCS
Select this checkbox to put the run/debug configuration under version control and make it available to other team members.
The shared run/debug configurations are kept in separate xml files under .idea\runConfigurations folder, while the local run/debug configurations are kept in the .idea\workspace.xml .
The tree view of run/debug configurations has a toolbar that helps you manage configurations available in your project as well as adjust default configurations templates.

Delete the selected run/debug configuration. Note that you cannot delete default configurations.
Create a copy of the selected run/debug configuration. Note that you create copies of default configurations.
The button is displayed only when you select a temporary configuration. Click this button to save a temporary configuration as permanent.
View and edit the template (that is, the default run/debug configuration settings). The templates are displayed under the Templates node and used for newly created configurations.
Move the selected run/debug configuration up and down in the list.
The order of configurations in the list defines the order, in which the configurations appear when you choose a run/debug configuration.
Default templates of run/debug configurations are always sorted alphabetically.
To create a folder, select the configurations within a category, click , and specify the folder name. If only a category is in focus, an empty folder is created.
Then, to move a configuration into a folder, between the folders or out of a folder, use drag or and buttons.
