The Easiest Cluster? Automating Docker Swarm

[@RobertFabiano]

Super useful (and timely) video! Thanks again! 👍

[@GrollerG]

Hi Jim, Thanks for these videos!

[@Jims-Garage]

My pleasure!

[@kgottsman]

Thanks for the videos. I am glad your are moving to Ansible instead of Bash scripts. Much much easier with more flexibility and adaptability.

New watcher, however as a Linux sysadmin/devops engineer, I’ve been really enjoying not just your setup videos, but the extra “best practices” config you throw in there. You just got a sub! Completely separately, if your last video was “stop using docker swarm” why are you using docker swarm?

[@Jims-Garage]

@@KILLERTX95 thanks! It was stop using docker, i.e., use swarm instead

[@KILLERTX95]

@@Jims-Garage oh, must have misread.

[@ekekw930]

Great video. I have been migrating my Docker apps to my RKE2 cluster for learning Kubernetes. Any plans on future Kubernetes videos?

[@Jims-Garage]

@@ekekw930 yes, I will be coming back to Kubernetes in the future

[@RobertFabiano]

Would be sweet if you added Traefik as the load balancer.

Hi Jim, great video as always. Just wondering why you didn't use the swarm services ansible module for deploying portainer? Was it just easier to use your existing compose? Nice to see NFS, but how would you handle services that have sqlite files and other databases that don't play nicely over NFS? Cheers

[@ricardocosta9336]

Niceeeee one one video 🎉"🎉🎉

[@angldavd]

I think it would be an interesting combination: Proxmox HA Ceph HA Docker sawrm Dockge

[@Jims-Garage]

@@angldavd I'll have a look. I'm doing half of that at the moment with Kubernetes

[@jonip5623]

Hello Jim! Thank you for a great video! Can you ilmpelent keepalived to this setup to have LB address and do not worry about node going down? Or is there better way? Or maybe, video is already on the way? ;)

[@aldi3556]

Hi Jim, thanks for the video, Quick question havé you tried dockge from the guy that created uptime-kuma? I find it better than Portainer in so many ways

[@Jims-Garage]

Not yet! I have seen others covering it though, it does seem impressive.

[@aldi3556]

I havé both and since I installed Dockge, Portainer has been collecting dust!

[@kgottsman]

@@Jims-Garage Dockge is a great option. Komodo is another with lots of GitOPs functionality. I don't think either officially support Swarm though.

[@Jims-Garage]

@kgottsman thanks, I'll take a look at it

[@Kermit2k]

Quick question Jim. How much disk space are you allocating to your docker swarm vms?

[@Canneverdoit]

Any reason to go with docker swarm instead of kubernetes?

[@Jims-Garage]

@@Canneverdoit no. Use k3s in my lab (I have a series on it). Swarm is probably more appropriate the majority of people.

[@Canneverdoit]

@ yea I did already watch you series, which was great btw! But I see that kubernetes might be overkill compared to docker swarm for homelab usage.

[@ivanmalinovski7807]

@@Jims-Garage If there's no reason to go with Swarm over Kubernetes, why is Swarm more appropriate for most people?

[@Jims-Garage]

@@ivanmalinovski7807 swarm has its place. If you need lightweight HA with less complexity it's a good option.

[@kurtbrown7504]

How about use ceph and keep alive in this eetup.

[@Jims-Garage]

Yes, that could work. Ceph is great, I use it for my K8S cluster, however, it's not kind to consumer devices. I find the NFS to be more performant on low spec machines.

[@iscultas]

Hi, mate. You are understanding and using Ansible roles incorrectly. Even how you are naming them suggests that these must be tasks instead. If you want to use roles, you need to create only two: manager and worker, respectively, and assign them to proper hosts.

[@MarcioZbs]

I gave up on Swarm and advise any one to do the same, the Overlay Network IP Exhaustion issue will hit you sooner or later.

[@mikerthinks]

Geo-Politically motivated poster removal?

[@Jims-Garage]

Haha, good spot. No, it's already back up - cleaning!

[@ClayBellBrews]

I too tried it, but nvidia support under swarm is a nightmare; avoid it at all costs. This is NOT the same code base as Docker. It also has issues with macvlan;
