Rollback and Prune previous versions

[zaus]

Describe the feature

This may be more a pertinent to using SAM template's AutoPublishAlias or SemanticVersion rather than dotnet CLI, but deployment creates several artifacts in the S3 deployment bucket and never removes them. It's not clear how to get back to a previous version (either via CLI or in Console, as no changeset history is listed?), and I've only seen suggestions for manually cleaning up old stuff or awkward lifecycle policies or installing random 1stparty or 3rdparty plugins to do it for you.

The Serverless Framework's prune plugin handles this for the Lambda versioning, and I think it already cleans up old deployment artifacts?

Use Case

• Clearing old micro-version/minor changes from test attempts
• Reverting deployment with breaking change

Proposed Solution

Specifying a major/minor version number in template and remembering to update it when you want an explicit version, or deploying with an --autoversion flag; either should save separate changesets (is that how you're supposed to do it with Cloudformation Stacks?). Then:

dotnet lambda rollback-stack --v <EXACT_VERSION_NUMBER>

or

dotnet lambda rollback-stack --v "-<number of versions back"

or

dotnet lambda rollback-stack # just to previous version

To get back to the indicated version.

Also, specifying something like --retainVersions 5 to keep the last 5 deployments for rollback.

I'll also just settle for guidance if this is something that can be accomplished "natively"

Unsure if this is something that is available in .NET CLI Extensions tooling. Needs review with the team.

I guess I shouldn't keep my hopes up if this is so old... aws/aws-sam-cli#1654
