Question

Is it possible to use docker compose to build a swarm kubernetes cluster

Answer 1

Yes, one can deploy a stack on Kubernetes with docker stack deploy command, the docker-compose.yml file, and the name of the stack.

Here's an example:

$docker stack deploy --compose-file /path/to/docker-compose.yml mystack

$docker stack services mystack

You can see the service deployed with the kubectl get services command 

$kubectl get svc,po,deploy
