That's the thing, we use k8s in production and I just used docker-compose for testing in my device environment for the sake of simplicity. Though over time it became not so simple to maintain two parallel config as the system grown up.

that's one of the reason we decided to jump on swarm. And seeing how Swarm has matured and added features, we are very happy.

Azure also comes with a Swarm-mode deployment template which is pretty great (https://github.com/Azure/acs-engine/blob/master/docs/swarmmo...). However, setting up and running Swarm has been a pleasure.

This is very interesting. I've been looking for middle ground between Dokku and Kubernetes, I'll give swarm a try. Does it handle ingress at all? vhosts, TLS certificates, etc?

If you're paying for EE, then UCP can do a lot for you. We're using the HRM heavily, and it's very handy.

ingress is the most beautiful part of Swarm - it is built in.

however, it does not do termination. You should trivially include a haproxy/nginx pod/service/vm to do the termination for you.

One of the cool new infrastructure features is Docker Cloud - which allows you to "bring your own nodes" for 15$/node/month and setup Swarm. https://docs.docker.com/docker-cloud/cloud-swarm/using-swarm...

Helm makes this easy. It’s great, just use the templating features and not the package management stuff.

We found the same thing after the package management stuff caused issues in prod.

We rolled our own go program that just does go tpl substitution in yaml with overrides like helm. Works on charts out of the box, but instead of talking to a service, it outputs a yaml manifest ready to kubectl apply.

We've thought about open sourcing it. It took us literally a day to put together and had worked without flaw for 8 months in production.

Cool! I just don't use the package management stuff. My workflow also has local manifest template rendering, but I use helm-template[0]. My chart is just a local directory, not a package or anything. Then, to release:

* Render the chart and run it through kube-cloud-build[1] to make sure my containers are all built before I deploy: `helm template /path/to/chart | kube-cloud-build -r repo`

* Deploy with helm: `helm upgrade RELEASE_NAME /path/to/chart`

Has been working really well for me.
