‘docker ps’ vs ‘docker container ls’

There is no much difference in between the docker ps and docker container ls as shown in the image below.

• docker container ls: This command lists all the currently running containers. The output shows one container with the following details:
• CONTAINER ID: 1041a2d84eff – This is the unique identifier for the container.
• IMAGE: nginx – This indicates that the container is running an nginx image, which is commonly used as a web server or reverse proxy.
• COMMAND: “/docker-entrypoint…” – This is the command that was used to start the container, and it has been truncated in the display. The full command is likely something like “/docker-entrypoint.sh nginx -g ‘daemon off;'”, which is the default command for nginx Docker images.
• CREATED: 57 minutes ago – The container was created 57 minutes before the command was run.
• STATUS: Up 57 minutes – This shows that the container has been running since it was created.
• PORTS: 80/tcp – The container has exposed port 80 for TCP traffic, which is the standard port for HTTP web services.
• NAMES: adoring_bell – Docker has automatically assigned a whimsical name to the container, in this case, “adoring_bell”.
• docker ps: This is an older command that serves the same purpose as docker container ls, which is to list all running containers. It’s commonly used for its brevity and gives the same output as docker container ls.

The output for both commands is identical, showing that there is one running container based on the nginx image. The fact that the commands have been run in sequence with identical output suggests that there has been no change in the status of running containers between the execution of the two commands. The container seems to be running normally, but without additional context, it’s not possible to determine what service it is providing or if it is part of a larger application or service.

he “docker ps” command is used to list all the running containers in the docker host. With the help of some filters, you can get the output of all the containers in the docker with are running and that are stopped. it shows the list of active containers that includes details about each one, including its name, ID, creation image, program being run inside it, creation time, and status.
