yarn missing from the aws/codebuild/standard:7.0 image

[juliannicholson]

The aws/codebuild/standard:6.0 image contained yarn. However the aws/codebuild/standard:7.0 does not. This is causing our codebuild's to fail as we rely on the yarn executable.

I can see lines in the aws/codebuild/standard:6.0 dockerfile installing yarn but these aren't in aws/codebuild/standard:7.0. Please could these lines be added back in so that the container image contains yarn.

Yes, this is a big breaking change and given that e.g. AWS CDK with projen uses yarn by default this is not a great idea.

Thanks for reporting the issue. I believe yarn was taken off due to the signature expiry issue that crops up periodically. For example, #595. When the signature expires, it breaks build for everyone using the image, irrespective of whether they needed yarn or not.

We apologize for this regression in the newer images and will look to add this back at the earliest, once we address the yarn key expiration issue in a more automated manner.

The same (yarn is missing) is for aws/codebuild/amazonlinux2-aarch64-standard:3.0. It was in the previous version as well.

Yarn is also missing from the AL2 x86_64:5.0 repo. I manually had to copy the 4.0 yarn installation lines into our buildspec in order for it to work.

EDIT: the above suggestion is not the best way to workaround this issue.

Running npm install -g yarn is as effective, and will net the same result.

NOTE: this is only for yarn 1.x. Please follow the 2.x+ docs for 2.x installation via corepack.

#657 Should resolve this.

Fixed in the latest release 3228c52#diff-c1ea454e65b48efad7d52406144e50f8459244517f0eb25a5ec3da4f865a3129

@leoherran-aws my proposed solution in #657 is much simpler and doesn't require yum and/or GPG key pulls. It also is the recommended method to install per the Yarn V1 docs.
