You have access to a Linux server with a few Docker containers. Some containers are running, some have exited successfully, and one appears to have crashed. Your goal is to list all containers and inspect their statuses.
Explore the environment and answer the questions below.
Hint 1: Listing currently running containers 💡
Listing containers is one of the most basic operations in Docker.
You can use docker ps (alluding to the ps command from Unix) or a longer but more explicit docker container ls command for it.
Hint 2: Listing all containers in the system 💡
By default, docker ps shows only running containers.
Run docker ps --help to see if there is a way to show all containers,
including exited and crashed ones.
Hint 3: Enhancing the "docker ps" output 💡
The nicely-looking short IDs that you get from the default docker ps output are actually just prefixes of the full container IDs.
You can use docker ps with the --no-trunc flag to see the full IDs.
Hint 4: Inspecting container details 💡
While some attributes of containers can be found from the docker ps output,
it's often useful to inspect the container in more detail.
You can use the following command to inspect the container's details:
docker inspect CONTAINER_ID|NAME
Or its more explicit variant:
docker container inspect CONTAINER_ID|NAME
