Options to migrate from Swarm to K8s
Back in 2017, I decided that our applications should be deployed in a Swarm cluster. Fast forward to 2020, we have more than 50 stacks running and the number is still counting on. I have no regret of that decision: (1) The simplicity of docker-compose file format allows us to deploy a new stack very quickly, skipping the ops part. Any developer can have a look at the stack file and say exactly what’s going on.
