Description hiraku.sugiura 2022-07-24 01:20:13 UTC
Please add crictl as dependecies to kubernetes-kubeadm.
I can not  execute "kubeadm init" for now.

Comment 1 Brad Smith 2022-07-24 15:02:48 UTC
Could you please provide an example of the error or response you see from 'kubeadm init'?

Steps to Reproduce:

# Install Fedora 36
...
$ sudo dnf install kubernetes-node kubernetes-kubeadm
...
$ sudo systemctl enable --now kubelet.service
Created symlink /etc/systemd/system/multi-user.target.wants/kubelet.service → /usr/lib/systemd/system/kubelet.service.
$ sudo emacs /etc/sysctl.d/k8s.conf
$ sudo cat /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables  = 1
net.ipv4.ip_forward                 = 1
$ sudo systemctl reboot
...
$ sudo kubeadm init

Comment 3 Anthony Rabbito 2022-07-25 14:44:02 UTC
It looks like crictl isn't currently packaged. I would think this should usually be a dependency on containerd/cri-o but maybe there's usecases where they don't need it. Either way we will need to get it packaged for Kubernetes.

Comment 4 Anthony Rabbito 2022-07-25 15:29:40 UTC
cri-tools does exist in Fedora. Max plans on getting it up to date today.

Comment 5 Brad Smith 2022-08-17 20:07:34 UTC
Added requires for kubernetes-kubeadm rpm in version 1.24.3-3. Should show up in  rawhide tomorrow (18 Aug 2022).
