Docker {Tools}

From personal use

• to list all containers, including ones not currently running docker container ls -a
  • useful to restart a container running just temporarily e.g. Nextcloud local instance for pulling large video out of an iPhone
• change the ports values in docker-compose.yml if docker-compose up fails because of a used port, typically 8080
• docker stop instance_name: stop the instance
• docker start instance_name: start the instance
• docker rm instance_name: delete the instance
• docker logs instance_name: get console output if the instance
• docker inspect instance_name: get details of running instance including IP address
• docker ps: list running instances
• docker help : the MOST important command ;)

From SundayGeekBrunch2016InventingOnPrinciple3

• made first own Docker file
  • that can be directly built via PIMSREDemo-Dockerfile?action=source then run
• difference between container and images
  • an image, result of a build from a Dockerfile, is not running
• exiting container if process in daemon mode
  • depending on the target usage but if passed the -d parameter must make sure to run the target process in foreground
• docker attach to access the terminal inside a running container
  • if you need a shell instead exec –it containername /bin/bash
    • note that vi/vim might not be present, consider sed instead to edit configuration files
• docker -p 80:80 for HTTPd port mapping

Note

My notes on Tools gather what I know or want to know. Consequently they are not and will never be complete references. For this, official manuals and online communities provide much better answers.
