Description: `
|
||||
This command will generate labels for each service which correspond to the
|
||||
following format:
|
||||
This command will generate labels for the main recipe service (i.e. the service
|
||||
named "app", by convention) which corresponds to the following format:
|
||||
|
||||
coop-cloud.${STACK_NAME}.${SERVICE_NAME}.version=${IMAGE_TAG}-${IMAGE_DIGEST}
|
||||
coop-cloud.${STACK_NAME}.version=${RECIPE_TAG}
|
||||
|
||||
The <recipe> configuration will be updated on the local file system. These
|
||||
labels are consumed by abra in other command invocations and used to determine
|
||||
the versioning metadata of up-and-running containers are.
|
||||
The ${RECIPE_TAG} is determined by the recipe maintainer and is retrieved by
|
||||
this command by asking for the list of git tags on the local git repository.
|
||||
The <recipe> configuration will be updated on the local file system.
