I came across this post:
Is anyone using this? Does it still work?

Speaking of systemd services, here’s my systemd unit file:
[Unit]
Description=Erlang release startup
[Service]
Type=simple
User=webserver
Group=webserver
ExecStart=/opt/webserver/web/bin/web start
ExecStop=/opt/webserver/web/bin/web stop
# read environment variables from this file, including secrets
EnvironmentFile=/opt/webserver/web_env
# shouldn't matter. whatever
WorkingDirectory=/opt/webserver
[Install]
WantedBy=multi-user.target
Just dump in /etc/systemd/system/webserver.service (after adjusting paths, of course). IIRC this was mostly copy-pasta from somewhere else, so I can’t take credit for anything but the EnvironmentFile line.

I use Distillery and Edeliver to help deploy on an Ubuntu VPS, it’s worked pretty well so far. This guide was really useful for me: https://medium.com/@zek/deploy-early-and-often-deploying-phoenix-with-edeliver-and-distillery-part-one-5e91cac8d4bd.
This guide (https://dreamconception.com/tech/phoenix-automated-build-and-deploy-made-simple/) has a more involved setup but is probably more robust as it uses Ansible and handles other aspects of managing deployments.
There are more managed services, like Heroku or Gigalixir worth exploring.

I am using libcluster in GCP Kubernetes. I don’t recall any specific tutorials, but I know there are a few that cover it. If you hit a dead-end, let me know and I can share how I do it.

I have two deployment strategies:
-
Quick-and-Dirty
Deploy to Heroku. Many downsides, but the upside is how fast / simple it is. You can always use ngrok for something really quick and dirty, but Heroku is pretty convenient. -
For everything else…
I deploy to GCP Kubernetes. A much more powerful setup, with each Elixir container connected on a private network via libcluster k8s DNS. Kubernetes and Elixir go VERY well together. In some respects, k8s container orchestration feels familiar to how the BEAM / actor model works, but higher-level. I have two apps currently in production on this setup, both with essentially zero downtime due to rolling updates (no need for hot updates). Receiving a SIGTERM from Kubernetes can be caught in Elixir, giving you the ability to gracefully kill off processes in the reverse order they were created. This gives you time to stash things in cache, wait for any HTTP responses, and hand off processes to other container.
For what it’s worth, I don’t think I have come across a deployment / devops solution that checks as many boxes as Google hosted Kubernetes.
