It was time to update my Simple RKE2, Rancher install blog and video : youtu.be/ONes6pv_9J4
In 15 minutes you too can have a simple cluster.

@TechnoTimLive You can run VM’s and containers on the same OS. And it’s open source.

@TechnoTimLive If you are leaning into gitops, then I would build a single node k3s cluster and use either fleet/rancher or flux or argo. Not sure if WatchTower (containrrr.dev/watchtower/) or @portainerio can leverage gitpos on a local docker.

@clemenko Thanks! Rate of change really depends on when I add/remove workloads or they have container image updates. Basically I want GitOps for compose where git is the driver of change. Basically Flux for Docker.

After switching back to Docker Compose for my "Home Production" things have been remarkably stable compared to k3s, however it's definitely not as easy to manage as I would like it to be. Remoting in and configuring YAML and then restarting services just feels icky compared to what I have been use to with GitOps and Kubernetes... I am considering 3 options...
1) Build some kind of GitOps automation for Docker Compose that would allow me to commit my Compose files and CI would then create / update the workloads on the target machine (this comes with a whole host of challenges and non standard-code I would have to write.). There isn't a great pattern for doing this in the wild so it could be fun to build a solution for this and might fill a void for HomeLab for those wanting to run Docker only with GitOps.
2) Build a single node k3s cluster so I can manage it just like I do with my other Kubernetes clusters.
3) Nothing. Stay the course with Docker Compose and manage via SSH and CLI.
I am starting to lean towards option 2. This would give me the power of k8s and the entire ecosystem, but not the HA challenges (that I don't need anyway) for my "Home Production".
I would still treat it like a cluster (with load balancers, ingress controllers, and possibly even using Multus (again) - rather than using NodePort for networking, and I could use the Local Path Provisioner for storage so I don't have to bring in complex like Longhorn or Rook. There are also simple solutions like democratic-csi if I don't want to use Local Path, but then again I want this to be simple.
I think this would give me containers for services but also the management and ecosystem of k8s, without the complexity and headaches of traditional storage providers because there is only a single node to manage. This is part of the reason I like Docker for storage, it's simple because there is only 1 node and the files are on the local disk. I don't need HA for my "Home Production" and most of these workloads for home don't support HA anyway. A single node k3s cluster does have some overhead, but it might be worth the trade-off for management and ecosystem...
Have I gone full circle? (again)♻️. .
Is there another way? (GUI-less mind you)

Thanks @Jefflingguy for the article on Corporate Open-Source being Dead.
Opensource is not dead, it's broke!

Me: I moved a lot of apps that were running in Kubernetes over to a new dedicated app server that's running Docker only, using compose. So Plex, Home Assistant, and Scrypted were all moved there and they can share the same video card!
Wife: What?
Me: Plex will work better and the lights will work again.

Got a good question yesterday about Harvester and Rancher Integration, so I made a video.

It has taken me a week to realize the gravity of what the flight attendants, a nurse named Rachel and I were able to do to for a sick woman on flight 1428. @SouthwestAir please thank the flight crew from Sunday May 5th! Grateful we were able to prevent things from getting bad.

Was a blast helping a co-worker Nick Grasso ( @1tzRyuk ) understand and install Rke2, Rancher and Longhorn. This was is first time using SSH and Putty!
Let us know if there is anything you want him to learn!

@TechnoTimLive I just tested it 3 times with cilium/ubuntu and cilium/rocky.

make sure you are updating the kernel and rebooting.
