kindest-node-crio

Custom kind config and node image to work with cri-o

Tested on CentOS 8 w/ podman 1.9. Make sure cgroupsv1 is used, as runc/k8s requires that for now.

1. Build the image

[root@localhost ~]# podman build -t localhost/vrutkovs/kindest-node-crio:v1.17.2 .
...

2. Build kind from the master

[root@localhost ~]# GO111MODULE="on" go get sigs.k8s.io/kind@master
...

3. Start a new cluster

[root@localhost ~]# export PATH=$PATH:/root/go/bin/
[root@localhost ~]# export KIND_EXPERIMENTAL_PROVIDER=podman
[root@localhost ~]# kind create cluster --config=2workers.yaml 
using podman due to KIND_EXPERIMENTAL_PROVIDER
enabling experimental podman provider
Creating cluster "kind" ...
