Notes

• Configured aws-arm-core-2-default which seems to be sufficient. It finishes about the same time as the x64 build.
  • aws-arm-core-2-default: Ubuntu Linux, 2 ARM CPUs, cheap without durability guarantee
  • Available self hosted runners.
• Removed the cache arguments as docker build doesn't support the --cache-to only the --cache-from which is not that useful in the first build.

Issues

• multi platform docker build (release.sh) seems to fail during amd64 mvn dependency:get with timeout (download.sh).
• Docker.io too many requests
  • 429 Too Many Requests - Server message: toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading
• Self hosted runner isn't picking up the job, sometimes for a whole hour.
  • Waiting for a runner to pick up this job...
