Serverless Prune Plugin
Following deployment, the Serverless Framework does not purge previous versions of functions from AWS, so the number of deployed versions can grow out of hand rather quickly. This plugin allows pruning of all but the most recent version(s) of managed functions from AWS. This plugin targets Serverless 1.x.
Install with npm:
npm install --save-dev serverless-prune-plugin
And then add the plugin to your
Alternatively, install with the Serverless plugin command (Serverless Framework 1.22 or higher):
sls plugin install -n serverless-prune-plugin
In the project root, run:
sls prune -n <number of version to keep>
This will delete all but the
n-most recent versions of each function deployed. Versions referenced by an alias are automatically preserved.
A single function can be targeted for cleanup:
sls prune -n <number of version to keep> -f helloWorld
The previous usage examples prune the default stage in the default region. Use
--region to specify:
sls prune -n <number of version to keep> --stage production --region eu-central-1
This plugin can also be configured to run automatically, following a deployment. Configuration of automatic pruning is within the
custom property of
serverless.yml. For example:
custom:prune:automatic: truenumber: 3
To run automatically, the
automatic property of
prune must be set to
true and the
number of versions to keep must be specified.
This plugin can also prune Lambda Layers in the same manner that it prunes functions. You can specify a Lambda Layer, or add the flag,
custom:prune:automatic: trueincludeLayers: truenumber: 3
A dry-run will preview the deletion candidates, without actually performing the pruning operations:
sls prune -n <number of version to keep> --dryRun
sls prune --help
