[QUESTION/HELP] Kubectl cannot connect to 0.0.0.0? 127.0.0.1 works instead (MacOS)

[southwolf]

Not sure if it's a bug or what,
K3d creates a cluster ( k3d cluster create k3d-default ) with a kubeconfig file saying server: https://0.0.0.0:57156.
When I try kubectl get pods -A it just times out.
Later I changed the server address to https://127.0.0.1:57156 and everything works.

OS: MacOS Monterey 12.2
Docker: Docker for desktop MacOS 4.5.0
K3d: 5.3.0

Hi @southwolf , thanks for opening this issue!
You can specify the use host in the k3d config file:

kubeAPI:
  host: "127.0.0.1"

k3d does a lot of guessing to get the correct value there and falls back to the default 0.0.0.0 if it can't determine a valid value, which happens from time to time in Docker for Desktop environments.
