Like many, I’ve been looking for a way to deploy containers in our environment securely and efficiently with a minimal amount of fuss. After taking a hard look at Kubernetes, I came to the realization it might be a little too complex to roll out in our environment, so I started looking at Consul + Nomad. I’m currently using Terraform and Vault heavily in our environment, and I’m pretty comfortable with the HashiCorp way of doing things, so this seemed like a good option.
Pretty quickly, we were able to get something working, but without a load balancer doing the translation between the randomized ports Docker + Nomad gives you, fitting it into our environment would be a challenge. FabioLB seemed pretty popular, but I found the documentation really lacking in some areas, so I concentrated my efforts on Traefik.
Since getting the load balancing right was important, this is where I spent the bulk of my time.
Things we wanted from the solution:
An explanation of the magic:
The end result is that developers can build and test their apps locally, and when they commit their changes to Github they can be built and deployed to end users without needing to manually configure certificates or DNS.
