<div class="bookmark-description">Getting started with Docker on your VPS is pretty straightforward, and once you're set up via this Docker tutorial, it's like you've "leveled up" in DevOps. Docker is a platform for designing, building, and launching "containers," which are isolated environments containing all the software and configuration files necessary to run a service or application. <a href="https://blog.ssdnodes.com/blog/getting-started-docker-vps/" target="blank" rel="noopener">Link.</a>&nbsp;</div>

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
