• Top Docker Commands That You Need to Master

I. Docker Image

Create an image:

1. Create a Docker file:
   .dockerfile

   mkdir Docker_images
   cd Docker_images
   vi Dockerfile
   FROM ubuntu
   MAINTAINER simpli
   RUN apt-get update
   CMD ["echo", "Welcome to Simplilearn"]
   

2. Build a Docker Image with Dockerfile and tag:
   Git Bash

   docker build -t simpli_image /D/Docker_images  => [location of your dockerfile]
   

Check the images we have:

Delete some image:

II. Docker Container

Create a container based on the image:

Git Bash

docker run --name simpli_container simpli_image

Display a list of launched containers:

Git Bash

docker ps -a

Rename an existing container:

Git Bash

docker rename [CONTAINER_NAME] [NEW_CONTAINER_NAME]

Pause a running container:

Git Bash

docker pause [CONTAINER_NAME]

**Stop a running container: **

(somehow directly deleted the container)

Git Bash

docker stop [CONTAINER_NAME]

**Restart a running container: **

(somehow directly clear the setting of container)

Git Bash

docker stop [CONTAINER_NAME]

Removes all the stopped containers:

Git Bash

docker container prune [OPTIONS] 

Quit and delete the running containers:

Git Bash

exit

Remove an existing container:

Git Bash

docker rm [CONTAINER] 

Create a new image from a container’s file changes:

Git Bash

docker container commit [OPTIONS] [CONTAINER_ID] [NEW_IMAGE_NAME]
