If you want to thrive in the modern cloud-first world, you need to know Docker. But don’t stress, this course will give you all the skills you need.

To kick things off, you will learn how to deploy apps with Docker Compose, a key tool for managing multi-container applications running in single-engine mode. You will then move onto Docker Swarm which will allow you to stand up containers and orchestrate them at scale.

Towards the back half of the course, you will take a deep dive into Docker Networking, deploying apps with Docker Stacks, and some of the industry tools used for keeping Docker secure.

By the end of this course, you will be equipped with the knowledge and tools to run Docker at scale, no matter how many containers you have.

Docker Deep Dive: Advanced Techniques

Which of the following file formats can be used to define compose files?

Which of the following file formats can be used to define compose files?

Map port 8000 inside the container to port 8080 on the Docker host.

Map port 8080 inside the container to port 8000 on the Docker host.

What does the following command in the Compose file do?

```YAML
ports:
    - target: 8000
      published: 8080
```

What does the following command in the Compose file do?
<pre><code class="language-YAML">ports:
 - target: 8000
 published: 8080
</code></pre>

If you want to specify an alternate file other than `docker-compose.yml`, you need to specify it with the `-f` flag.

It is used to specify an alternate working directory.

What is the purpose of the `-f` flag in the command below?

```shell
docker-compose -f educative.yml up
```


What is the purpose of the <code>-f</code> flag in the command below?
<pre><code class="language-shell">docker-compose -f educative.yml up
</code></pre>

The lifecycle of volumes depends on the applications they serve.

The lifecycle of volumes depends on the applications they serve.

It stops the Compose app without deleting its resources.

It stops and then deletes the Compose app.

It shows the current state of the Compose app.

What does the <code>docker-compose down</code> command do?
