What happened:

What you expected to happen:

kind create cluster
enabling experimental podman provider
Creating cluster "kind" ...
 ✓ Ensuring node image (kindest/node:v1.20.2) 🖼
 ✓ Preparing nodes 📦
 ✓ Writing configuration 📜
 ✓ Starting control-plane 🕹️

Set kubectl context to "kind-kind"
You can now use your cluster with:

kubectl cluster-info --context kind-kind

Have a nice day! 👋

How to reproduce it (as minimally and precisely as possible):

Use a distro with >=Podman 3.0 with short-name-mode="enforcing" enabled in /etc/containers/registries.conf

Install kind as per the documentation. Try to create a cluster.

Anything else we need to know?:

Container short name mode for Podman has been set to enforcing by default for Fedora 34 and newer. This brakes the current scripts.

To fix this you can set the setting to short-name-mode="permissive". This should be added to the known issues page.

As a more robust fix, kind should fully specify image sources in its scripts.

Environment:

  • kind version: (use kind version): kind v0.10.0 go1.15.7 linux/amd64
  • Kubernetes version: (use kubectl version): N/A
  • Docker version: (use docker info): Podman Version: 3.1.0
  • OS (e.g. from /etc/os-release): Fedora IoT 34 Beta
