Hey there! So, I recently had to tackle the challenge of identifying all of our AWS CodeBuilds that were using soon-to-be-deprecated Linux images. Given the large number of builds in our project, manually sifting through each one would have taken forever.

To save time, I turned to the AWS CLI and crafted a command that would help me list out all of our CodeBuilds alongside their corresponding Linux images. This way, I could quickly identify the builds that needed updating.

Here's the command I used:

aws codebuild list-projects | jq '.projects[]' | xargs -I{} sh -c 'aws codebuild batch-get-projects --names "$1" | jq -r "\"\(.projects[].name) : \(.projects[].environment.image)\"" ' _ {} >> list.txt

It's a bit of a mouthful, but essentially what it does is use the list-projects command to fetch all CodeBuild projects, pipe them to jq to extract the project names, and then use xargs to pass each project name to the batch-get-projects command, which fetches the full project details including the Linux image. Finally, I used jq again to format the output as "project name : Linux image", and wrote the results to a file called list.txt.

Hope this helps you save some time too!
