Issue

Kind-Sigs on Debian GNU/Linux 11 fails to create kind cluster on Podman

Environment

Kernel Version

Linux cassandra 5.10.0-12-amd64 #1 SMP Debian 5.10.103-1 (2022-03-07) x86_64 GNU/Linux

OS Version

debuggerboy@cassandra:~$ lsb_release -a
No LSB modules are available.
Distributor ID:	Debian
Description:	Debian GNU/Linux 11 (bullseye)
Release:	11
Codename:	bullseye

Podman Version

Version:      3.0.1
API Version:  3.0.0
Go Version:   go1.15.9
Built:        Thu Jan  1 05:30:00 1970
OS/Arch:      linux/amd64

Kind Version

kind v0.12.0 go1.17.8 linux/amd64

Error Details

Please find the kind-sigs-cluster-creation-error.txt file attached below.

Fix

Copy the podman-fix-for-cluster-fail.sh file to your local.

  1. Run the sudo kind create cluster --name ko2 --config /home/debuggerboy/labs/kubernetes/anish-kind/multi-node.yaml command
  2. Run the command sudo podman ps -a
  3. See if you are able to see the 3 (clusters = 2 workers and 1 control-plane)
  4. once you see those containers are showing up in above command
  5. run the bash podman-fix-for-cluster-fail.sh command

Now the kind-sigs cluster will be created properly.

I am not having great experience in kubernetes cluster and kind-sigs. This is my primitive way of preventing my kind clusters from failing.

Thanks debuggerboy
