Container healthcheck loop

A year ago I was figuring out the topic and simultaneously practicing with puml. Sometimes it is very useful in a graphic form, it seems clear to me.

• Script

    FROM ubuntu 
    HEALTHCHECK --interval=12s --timeout=3s \ 
    CMD curl -f http://localhost/ || exit 1 
  

• Args

  • --interval=DURATION (default: 30s)
  • --timeout=DURATION (default: 30s)
  • --retries=N (default: 3)
  • --start-period=DURATION (default: 0s)
  • --start-interval=DURATION (default: 5s)

• Loop
