Troubleshooting section

Rate limiting issues

  • Issue:

Rate limiting in DockerHub sometimes prevent to pull the images if your cluster reach the DockerHub limit.

For example:

Failed to pull image "centos": rpc error: code = Unknown desc = Error reading manifest latest in
docker.io/library/centos: toomanyrequests: You have reached your pull rate limit. You may increase
the limit by authenticating and upgrading:
  • Resolution:

To prevent this you can authenticate your docker hub account

On the other hand, we'll move all the images to quay.io / registry.redhat.io to prevent this issue.

Code Analysis Failures

  • Issue:

Sometimes Code Analysis raises an error when mvn is running the maven install 'sonar:sonar':

  • Resolution:

Just rerun the pipeline and will succeed without changing anything additional. The results will succeed afterwards:
