How to prune only one AWS lambda function if there are multiple lambdas configured in one serverless.yml file?
Closed this issue · 3 comments
Problem Statement :
In serveless.yml we can configure multiple lambda functions under the functions key.
But now if we use the serverless-prune-plugin then the prune setting would get applied to all the lambdas.
How to restrict the pruning to just a specific lambda inside this serverless.yml file.?
Note : This needs to be done for automatic pruning.
Hi @bsk25
Right, currently automatic pruning is applied at the project-level, not function level. Can you describe a specific use-case for wanting to prune with differing parameters between functions?
I'm trying to gauge if this is best handled in the plugin because it's a relatively common need, or if you have a bit of an edge-case best handled externally: for example, you could have your CI/CD pipeline use the sls prune -f functionName
CLI command with specific configurations for each function and achieve your desired result.
Hello @claygregory ,
Wanted to test this for one lambda first in dev before deploying to PROD.
So, was checking if there is a configuration to restrict this to just one function.
Eventually, will be doing it at project-level.
Ah. Got it. Well then:
- I assume you're separating dev/prod by Serverless
stage
. Good news: prune always acts on the target stage within a target region. So in the case of automatic pruning, it will only prune to the stage/region to which you just deployed. - If manually pruning, you can specifically test pruning against a single function. You can also target a specific region or stage from the cli.
Hope this helps.
