Multi-node cluster spanning different devices for homelab #12878
-
|
👋 Hello, I'm currently in the construction of my home lab, before I'm investing much time into setting up Talos, I had a question in mind: can I create Talos-in-docker nodes which can join the control node hosted on a Raspberry Pi 5 (Talos, as an OS not docker)? I did look #8819, but my purpose is in reverse: control plane as an OS (rpi5), nodes as docker (ubuntu, debian, ...). K3s would have fit the bill, but management of it doesn't feel stable for me (i.e. IP address changes of the node), but it has the major plus point of being flexible in the deployment. |

You should be able to join workers from Docker as long as they can talk to your controlplane endpoint. Please keep in mind that things like Talos Linux solves this with KubeSpan, but there might be some unknown with KubeSpan and Docker. |

Thank you for the answer, then I can have a peace of mind for future upgrades to the cluster! 🙏 Btw, I randomly found #3990 which might interest viewers of this discussion. |

Please keep in mind that things like
kubectl logs <pod>require communication from the controlplane down to your worker node IP, which might not be there for Docker.Talos Linux solves this with KubeSpan, but there might be some unknown with KubeSpan and Docker.
