Docker

Docker is a container platform.

It's open source but if you go to the site, you won't be able to tell, you can just find out about pricing there. After looking at docker.com, go to https://github.com/docker/docker and look for installation instructions there.

I am following their instructions to install on two Debian systems, one co-located and one at home.

I want to set up containers for Geonode and Geoserver.

I know how fiddly Geoserver can be (it runs in Tomcat) and so I want to isolate it from the Debian host it will run on.

I already have PostgreSQL 9.5 running directly on the host, but my only intended use is as a backend for PostGIS/Geoserver, so I will probably follow along with the instructions here and containerize it too.

So in preparation for using Docker. I removed PostgreSQL and Tomcat from my host server.

Orchestrating Geoserver with Docker and Fig

I have no idea what Fig is, yet.
