General Troubleshooting Solutions

This section describes general troubleshooting solutions to some issues you might encounter.

Restarting Processes

Restarting processes is a frequent solution to issues especially on older clusters.

  1. Check running processes.
  2. Kill all processes.
  3. Start roles one by one in this order: Docker Daemon (all hosts), Master, Application, Worker (all hosts)
  4. Look at kubectl between each role start to ensure pods are starting.
  5. Check Role logs for errors.
