I have multiple different, independent AWS CodeBuild projects set up. All of them are using the aws/codebuild/amazonlinux2-x86_64-standard:3.0 image.
What I expect is for them to run concurrently, whenever a BitBucket webhook triggers them on PUSH. However, what happens is that one build from one build definition runs, whereas the others, belonging to different build definition projects are in QUEUED status, waiting for the first build to complete. Only then do they get the build environment provisioned.
I have also tried the ubuntu standard 5.0 runtime.
Is there a way to instruct CodeBuild to run different build projects in parallel, not waiting for each other to finish?
