Comment on GitOps for docker compose stacks
chakli@lemmy.world 1 day ago
Wondering, Just after how many containers does ops make sense? I have a dozen containers, I check for updates once a month manually. I update the compose/docker files manually and up my containers. In stages, because my git and my container registry are also containers. Also my dev is my prod env.
I think it depends on the rate of change, rather than the amount of containers.
At home I do things manually as things change maybe 3 or 4 times a year.
Professionally I usually do setup automated devops because updates and deployments happen almost daily.

If feel like, for me at least, GitOps for containers is peace of mind. I run a small Kubernetes cluster as my home lab, and all the configs are in git. If need be, I know (because i tested it) if something happens to the cluster and I lose it all, I can spin up a new cluster and apply the configs from git and be back up and running. Because I do deployments directly from git, I know that everything in git is up to date and versioned so i can roll back.
I previously ran a set of docker containers with compose and then swarm, and I always worried something wouldn’t be recoverable. Adding GitOps here reduced my “What If?” Quotient tremendously.

How many hosts do you manage? What k8 tools do you use? I have just one host, I use bind mounts for container generated config/data/cache in docker compose, for which I dont have backup, and if gone, I have to start from scratch. But i try to keep most config in git.

Currently, I have a 3 node Proxmox cluster with 6 kube nodes on it (3 masters, 3 workers). Lets me do things like migrate services off of a host so I can take it out, do upgrades/maintenance, and put it back without hearing about downtime from the family/friends.
For storage, I’ve got a Synology NAS with NFS setup and then the pods are configured to use that for their storage if they need it (So, Jellyfin, Immich, etc). I do regular backups of the NAS with rsync. So, if that goes down, I can restore or standup a new NAS with NFS and it’ll be back to normal.
