Common commands in Docker
Docker is a computer program that performs OS-level virtualization, also known as "containerization".

- 7. See the running processes in a container
- 8. List all commands with the help command
- 9. List all containers
- 10. Delete container by container ID
- 11. Force removal of running containers
- 12. Delete all containers with wildcards instead
1. Export nginx server container with a single command
docker container run --publish 80:80 nginx
Executing the above command will work as follows:
- Download the 'nginx' image from the Docker hub.
- Start a new container from that image.
- Open port 80 on the server IP.
- Routing traffic to IP containers, port 80.
2. Run a container in the background
docker container run --publish 80:80 --detach nginx
This command runs on nginx server in the background. Option to detach Docker running container in the background.
3. List all running containers
docker container ls
The above command lists all containers in Docker and their status.
4. Stop a container
docker container stop {containerID}
ContainerID can be found using the ls command listing the list of all containers. The container ID may be several digits, as long as it is unique.
5. Run the new container with the specified name
docker container run --publish 80:80 --detach --name linuxhost nginx
A new container with nginx web server image starts with the name linuxhost.
6. View container log
docker container logs {containerName}
The above command displays the log for the specified container. The name of the container can be obtained using the ls command listing the list of all containers.
7. See the running processes in a container
docker container top {containerName}
This command lists all running processes in the container. The name of the container can be obtained using the ls command listing the list of all containers.
8. List all commands with the help command
docker container --help
This command lists all user commands that can be performed on a container.
9. List all containers
docker container ls -a
This command lists all containers with any status in Docker.
10. Delete container by container ID
docker container rm {containerID1} {containerID2} .
This command will delete all non-running ID containers specified by spaces.
11. Force removal of running containers
docker container rm -f {containerID}
The -f option allows the rm command to remove a container running in Docker.
12. Delete all containers with wildcards instead
docker stop $(docker ps -a -q) docker rm $ (docker ps -a -q)
This command stops all containers first and then removes all of them. On Windows 10, use Powershell instead of the Command Prompt and the above commands will work.
Good luck!
