Docker is the most useful web development tool you’re not using. This course is your guide for building all kinds of web applications with Docker.

You will be introduced to Docker basics including its architecture, images, and containers. Then you'll run various databases and view them via CLI or Adminer. Next, you will learn how easy it is to use WordPress with Docker. After that is the Node.js app and its live editing and debugging with Chrome's devTools. Finally, you will make your own project to practice your Docker knowledge.

By the end of the course, you will be able to confidently use Docker in any of your further projects.

Docker for Web Developers

## Solution

The following command will run the `PostgreSQL`:
```text
docker run \
  -it --rm --name postgres \
  -p 3000:5432 \
  --mount "src=postgresdata,target=/var/lib/postgresql/data" \
  -e POSTGRES_PASSWORD=mysecret \
  postgres
```


* `-it` runs an interactive session.

* `--rm` removes the container after 
the container stops.

* `--name` is used to name the container as `postgres`.

* `-p` is used to define both the exposed port (left side of `:`) and the default port (right side of `:`) on which `postgres` is running.

* `--mount` is used to define a persistent Docker volume named `postgresdata`.

* `-e` allows the setting of required environmental variables. The default `postgres` user is created when not defining any user and the password is set using `POSTGRES_PASSWORD`.

> 📌 Connect the terminal to see the above command in action.
