Docker Cheatsheet

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

docker push [IMAGE]
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
