04/18/2025, 3:22 PMHi! I've had success running k3d on Rocky Linux, however, no luck at all on RHEL. Is this a known issue or am I missing something that would need to be done specifically for getting k3d working on RHEL?
Currently getting the following from k3d-server-0:
Copy code
The connection to the server 127.0.0.1:6443 was refused - did you specify the right host or port? Copy code
E0418 15:20:24.037687 240 memcache.go:265] couldn't get current server API group list: Get "<http://localhost:8080/api?timeout=32s>": dial tcp [::1]:8080: connect: connection refused

Likely firewalld or ufw blocking?

04/21/2025, 11:54 AMI repeated the same steps multiple times over the weekend on Rocky and Redhat. Rocky works every time and Redhat fails with the above errors every time. They're a 1:1 so I assumed what works of Rocky would work on RHEL. That does not seem to be the case. I would have hoped there would have been some sort of mention in the FAQ or something. I think there is a 2 year old open ticket on github issues that might be related..

04/21/2025, 4:45 PMI never got to test it on RHEL, so I really have no clue.
You're running a single node setup and the k3d cluster create command succeeds?
What are the versions? (OS, Docker, k3d, K3s)

04/21/2025, 4:59 PMI got it working with docker as root. Will try a rootless docker setup now. Maybe podman support is to oexperimental.
