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, a personal github 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!

Portainer

Traefik

Keycloak

Automatic backups

TODOs

• 2FA the control dashboards through keycloak
• geoblocking the control dashboards
• start the article with a demo of what we'll be making
• MAYBE:
  • portainer introduction (maybe)
  • traefik introduction (maybe)
  • add a "skip if you already know portainer and traefik"
