Artifacts Migration Tool
TeamCity provides a command-line tool dedicated to automatic migration of build artifacts from one storage to another. Currently, the tool supports migration from a local storage to Amazon S3.
To get the tool, go to Project Settings | Artifacts Storage and use the Download artifacts migration tool link in the top right corner of the page.
The tool has to be installed on the same machine where the TeamCity server is installed.
The address of the TeamCity server, TeamCity authentication token, and the list of artifact directories must be provided in the configuration file.
By default, the tool expects them to be located in
To use S3 storage as the target, the tool needs AWS credentials on the machine.
The AWS credentials can be supplied using any supported method.
Command Line Options
The tool supports the following command line arguments:
-p) — (required) the external ID of the project that needs to be migrated.
-r) — (optional) indicates whether the tool should recursively process all subprojects of the selected project.
By default, the tool runs in the interactive mode. During the first run, the tool creates a migration plan listing all artifacts in the source storage. Then, the tool asks you to select the next step:
Update the migration plan.
Show the migration plan.
Copy artifacts from the source storage to the target storage.
Revert the migration — in case of incomplete or interrupted migration, the tool will remove the copied artifacts from the target storage.
Delete artifacts from the source storage.
Forget the migration plan — discard the current migration plan.
If the tool fails, you can choose to update the migration plan to continue the interrupted migration.
If the tool finds an existing migration plan, it will ask you to select the next step right away.
Alternatively to the interactive mode, migration steps can be specified as additional command line arguments:
--create-migration-plan— creating or updating the migration plan.
--show-migration-plan— showing the migration plan.
--start-migration— copying artifacts from the source storage to the target storage.
--revert-migration— in case of incomplete or interrupted migration, removing copied artifacts from the target storage.
--remove-artifacts-in-source— deleting artifacts from the source storage.
--reset-migration-plan— discard the current migration plan.
If one or more of these steps are provided, the tool goes through them without asking for confirmation or input.
teamcity.storage.migration.host— the address (protocol, host, and port) of the TeamCity server.
teamcity.storage.migration.access.token— the TeamCity authentication token.
teamcity.storage.migration.artifact.directories— the list of TeamCity artifact directories separated with
teamcity.storage.migration.processing.threadCount— the number of threads that the tool should use for processing (by default, 4 threads).
teamcity.storage.migration.s3.threadCount— the number of threads that the tool should use for uploading data to S3 (by default, 4 threads).
teamcity.storage.migration.s3.forceVirtualHostAddressing— use the virtual hosted style of S3 URL addresses instead of deprecated path style (by default, true).
teamcity.storage.migration.s3.upload.numberOfRetries— the number of attempts the tool does when uploading data to S3 if it encounters errors (by default, 5).
teamcity.storage.migration.s3.upload.retryDelayMs— the initial delay between attempts in milliseconds (by default, 1000).
