• Container commands:
  • Always use command: ['sh', '-c', 'command'] for safety.
  • Do not put your command and parameters in a single string: command: ['cowsay Welcome to CKAD!']
    • The whole string 'cowsay Welcome to CKAD!' is considered as a command which will throw error
  • Common bash script with loop:

    # writes output of command to a file
    while true; do date >> /opt/time/time-check.log; sleep 2 ;done
