How to run a Docker container on SCALE for dummies?

[Jip-Hop]

Personally I find running Docker containers with docker-compose the most "dummy friendly" way of running Docker containers. I'm looking forward to migrate the containers I currently run on a Synology NAS to TrueNAS SCALE. If I could just use/tweak my existing docker-compose file, that would awesome. But reading through this thread I understand docker-compose isn't supported and may even be removed in a future update...

What are your ideas about the future & dummy proof way to deploy an existing stack of containers?

An existing stack? None, hard manual labor.


SCALE is mostly focussed around Apps and the road from docker-compose to apps really is a manual one.
Either manually creating the compose containers using the Apps UI or rewrithing them into Apps yourself.

Just start docker with an init-script.

I'm using this init-script to run Docker (and not Kubernetes) in combination with Portainer.

What's the best way to learn Kubernetes? I've been using using Docker for many years but just simple CLI stuff like "docker run", "docker ps -a", "docker image pull ...", "docker image prune" etc - stuff like that. Plus using Portainer to monitor containers and recreate them with the latest updates. Have avoided orchestration tools for the most part, other than dabbling with RancherOS once or twice. Thanks.

Thanks for sharing this! I was curious what docker only would look like and this seems like a pretty straightforward setup.

I'm in the middle of doing this myself. This is what I've found so far however I'm sure this is just the tip of the iceberg. Hope it helps!

Google has a very high level resource explaining Kubernetes or k8s https://kubernetes.io/
You mentioned Rancher, I started reading up on K3s which is Rancher's light weight version of k8s https://rancher.com/docs/k3s/latest/en/
Read up on helm https://helm.sh/
Use helm to install prebuilt containers listed at https://docs.k8s-at-home.com/
