Building a Container Cluster
As part of my certification journey, I am going to need to setup a small networking lab. I could easily do this with virtual machines, but that wouldn't be as fun. So I am joining everyone else and I am going to build me a small container cluster to play with. Lots of advantages to building one of these.
- Use Docker more
- Learn about Swarm or Kubernetes
- Learn about networking
- Play with tiny computers.
I can't really think of any disadvantages to doing it. I do have a list of decisions to make. I am going to list them out.
Since I will be using Docker, I have choices. I do not know if Apache Marathon w/Mesos works with ARM. I will do some research. The only tutorials I have found cover Kubernetes and Docker Swarm. I will do a little research and make a decision.
Most tutorials use the LAN ports and connect the cluster to a hub. There is tutorial that covers using the WIFI. I think to start I will go with WIFI in my build. It saves a little cost and looks cleaner, although not as cool.
Ah, the real question. I haven't did a lot of research on alternatives to the Raspberry Pi, so I am going to stick to the well known. So it is a choice between the Pi 3 Model B or Pi Zero W. The cost difference isn't much and I think having more compute would be better.
I will be posting up all the decisions that I made and why I made them. The shopping list will be posted also with a total cost. Expect more posts as I go about building my cluster.
