In this post, we will be going over how to set up a [portainer]() managed docker environment, and how to use it.
This is ideal if you want to host a personal website, a [blog](/posts/how-to-blog), a personal [github](git.gtz.dk) or whatever your development heart desire.
If you choose to follow along, by the end of it, you will have an environment where you can just add or remove docker based services. It's even quite secure!
