Docker Cheatsheet

#docker #devops #productivity #discuss

Docker is an open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure in the same ways you manage your applications. By taking advantage of Docker’s methodologies for shipping, testing, and deploying code quickly, you can significantly reduce the delay between writing code and running it in production. In this post, I will mention docker commands which we need or most of the use-cases.

Lifecycle Commands

  • Create a container (without starting it): 
docker create [IMAGE]
Enter fullscreen mode Exit fullscreen mode
  • Rename an existing container 
docker rename [CONTAINER_NAME] [NEW_CONTAINER_NAME]
Enter fullscreen mode Exit fullscreen mode
  • Run a command in a new container 
docker run [IMAGE] [COMMAND]
Enter fullscreen mode Exit fullscreen mode
  • Remove container after it exits 
docker run --rm [IMAGE]
Enter fullscreen mode Exit fullscreen mode
  • Start a container and keep it running 
docker run -td [IMAGE]
Enter fullscreen mode Exit fullscreen mode
  • Start a container and creates an interactive bash shell in the container 
docker run -it [IMAGE]
Enter fullscreen mode Exit fullscreen mode
  • Create, Start, and run a command inside the container and remove the container after executing command. 
docker run -it-rm [IMAGE]
Enter fullscreen mode Exit fullscreen mode
  • Execute command inside already running container. 
docker exec -it [container]
Enter fullscreen mode Exit fullscreen mode
  • Delete a container (if it is not running)

Enter fullscreen mode Exit fullscreen mode
  • Unpause processes in a running container 
docker unpause [CONTAINER]
Enter fullscreen mode Exit fullscreen mode
  • Block a container until others stop 
docker wait [CONTAINER]
Enter fullscreen mode Exit fullscreen mode
  • Kill a container by sending a SIGKILL to a running container 
docker kill [CONTAINER]
Enter fullscreen mode Exit fullscreen mode

docker build [URL/FILE]
Enter fullscreen mode Exit fullscreen mode

docker build -t <tag> [URL/FILE]
Enter fullscreen mode Exit fullscreen mode
  • Pull an image from a registry 
docker pull [IMAGE]
Enter fullscreen mode Exit fullscreen mode
  • Push an image to a registry

Enter fullscreen mode Exit fullscreen mode

Enter fullscreen mode Exit fullscreen mode

Enter fullscreen mode Exit fullscreen mode
  • Load an image from a tar archive or stdin 
docker load [TAR_FILE/STDIN_FILE]
Enter fullscreen mode Exit fullscreen mode

I'm missing 'docker exec -it [container] ' to execute a command inside the already running container. For example run /bin/bash
