Docker Managed by Portainer
This Blog post is meant to give you a better understanding of the process to get Portainer up and running. It will also allow you to see how it interacts with docker, and to learn how Portainer works from a ground roots level. We are installing the latest version of Ubuntu Server and the most recent version of docker. We are also installing an instance of Portainer as a delivery platform for microservices / apps.
Portainer and Docker will make your day-to-day duties easy.
