Merge 295fe153ad into 475f125f4b

Hello, I've added a small blockquote below the description to indicate that this method of accessing an indefinite number of function arguments has been superseded by the use of the spread operator via rest parameters for ES6+ compatibility.

+# 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.
