Serverless Prune Plugin

Deletes old versions of functions from AWS, preserving recent and aliased versions



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.

Serverless Build Status Coverage Status


Install with npm:

npm install --save-dev serverless-prune-plugin

And then add the plugin to your serverless.yml file:

  - serverless-prune-plugin

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.

Single Function

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 --stage and --region to specify:

sls prune -n <number of version to keep> --stage production --region eu-central-1

Automatic Pruning

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:

    automatic: true
    number: 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, includeLayers:

    automatic: true
    includeLayers: true
    number: 3

Dry Run

A dry-run will preview the deletion candidates, without actually performing the pruning operations:

sls prune -n <number of version to keep> --dryRun
