After recent update of Che addon before GA build the Che stopped to work in CDK 3.7.0 GA. When we try to start a workspace, it ends with an error:
Fails to start: Java on Ubuntu, Go on Ubuntu.
Starts well: CentOS JDK, CentOS Go.
After root cause analysis we found that it is failing because docker exec command is failing with laster docker bits in RHEL for non-Red Hat containers i.e. Ubuntu , busybox etc. Hence Che workspaces based on Ubuntu are failing. So this issue is not specific to Che but more widespread than that.
