+# 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.

+# Run A Hello World Program In Eclipse
+
+First, you'll need to create a new Java Project if you don't already have one
+to work in.
+
+From there, you can add a new _Class_ to the `src` folder of that project. I'll
+call mine `Greeting.java` and the only thing it will contain is a `main`
+method.
+
+```java
+public class Greeting {
+    public static void main(String[] args) {
+    	String name = args.length > 0 ? args[0] : "World";
+
+        System.out.println("Hello, " + name + "!");
+    }
+}
+```
+
+This method tries to read a name from the arguments given to the program at
+time of execution. If one wasn't provided the ternary falls back to `"World"`
+as the default name. It then prints the greeting to stdout.
+
+To run this program, we can either select _Run_ from the _Run_ menu (which will
+result in `Hello, World!`) or we can select _Run Configurations..._ from the
+same menu and add a custom name to _Program Arguments_ under the _Arguments_
+tab.
