How do you pass environment variables to the build container?

[jcavalieri]

Hi logandk,

I need to use a different container other than the default or lambci/lambda:build-ruby2.7 to target the aarch64-Linux architecture. So I'm using public.ecr.aws/sam/build-ruby2.7:latest-arm64.

I also have private gems I need to bring into the bundle. And there are two ways I know how to do that. Either by using a bundle config command or by environment variables, as explained here: https://bundler.io/man/bundle-config.1.html#CREDENTIALS-FOR-GEM-SOURCES

I've tried this, but I don't think the environment variables are being passed to the container.

provider:
  name: aws
  stage: ${opt:stage}
  region: ${opt:region}
  runtime: ruby2.7
  architecture: arm64
  environment:
    BUNDLE_GEMS__LONGEROUS__COM: "claudette:s00pers3krit"

And looking at this, it doesn't look like there is a way to do custom docker args: https://github.com/logandk/serverless-rack/blob/7364305bcbbf7f6cc6851497069a5a4cb91936b1/index.js#L42-L48

Is what I'm trying to do possible via configuration instead of needing to create a custom image?

Thanks, John

It looks like there is only one environment variable allowed and that is BUNDLER_ARGS.

@logandk would you be okay with a PR that allowed for more environment variables to be passed to the docker container?

Sorry, I missed this issue - would definitely accept a PR

Hi @logandk,

I'm no longer on the project where that was using serverless. Feel free to close this.

I'll reach out to my former group and let them know they could create a PR if they wanted.

Thanks, John
