# List Running Docker Containers
The `docker` CLI has a `ps` command that will list all running container by
default.
When I run it, I can see that I have a container running a Postgres database
and another running a MySQL database.
```bash
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
ba792e185734 postgres:latest "docker-entrypoint.s…" 12 days ago Up 12 days 0.0.0.0:9876->5432/tcp better_reads-postgres-1
7ca7c1e882e0 mysql:8.0 "docker-entrypoint.s…" 19 months ago Up 8 seconds 33060/tcp, 0.0.0.0:3309->3306/tcp some-app-db-1
```
It lists several pieces of info about the containers: the container id, the
image it is based off, when it was created, the running status, the port
configuration, and the name of the container
If I run `docker ps --help` I can see some additional options. One option is
the `--all` flag which will display all known docker container instead of just
the running ones.
