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

Deleting a container will delete its associated volume.

This writable layer of local storage is managed on every Docker host by a _____________. 

This writable layer of local storage is managed on every Docker host by a _____________.

Volumes enable multiple containers on different Docker hosts to access and share the same data.

Volumes can be mapped to specialized external storage systems.

Volumes are independent objects that are not tied to the lifecycle of a container.

Volumes are tied to the lifecycle of a container to enable memory handling.

Why are volumes recommended to persist data in containers? 

Why are volumes recommended to persist data in containers?

This will throw an error since we need to first create the `vol_educative` before mounting it onto a container.

Docker will create a volume named `vol_educative` for you on the Docker host.

Suppose a Docker host has no existing volumes in it. What will this command do then?
```shell
$ docker container run -dit --name educative --mount source=vol_educative,target=/vol alpine
```


Suppose a Docker host has no existing volumes in it. What will this command do then?
<pre><code class="language-shell">$ docker container run -dit --name educative --mount source=vol_educative,target=/vol alpine
</code></pre>
