Command

Run a container from an image

The syntax is as follows:

docker run –name <container_name> <options> <base_image> <command_to_run>

For example, to run a container from an Ubuntu image, open a Terminal and execute the bash shell with the following command:

docker run -name my-ubuntu -it ubuntu bash

Create an image from a Dockerfile

The syntax is as follows:

docker build <options> <folder_of_dockerfile>

For example, to create my_image from a Dockerfile in the current folder, run the following Docker command:

docker build -t image_name

List currently running containers

docker ps

List all containers, including stopped containers

docker ps -a

Start (a stopped) container

The syntax is as follows:

docker start -i <container>

The -i option keeps stdin (standard input) open and allows you to run commands in the container. To identify the container, you can either use the container name or ID.

Remove a container

docker rm <container>

Execute command in running container

The syntax is as follows:

docker exec <options> <container> <command>

For example, to open a bash shell in a running container called my_container, execute the following command:

docker exec –it my_container bash

docker images

Deleting images

Image IDs are space separated in this command:

docker rmi <image_ids>

docker inspect <container>
