Upgrade to new kubernetes versions #123

Open Rahulsharma0810 opened 2 years ago

Rahulsharma0810 commented 2 years ago

Is there a way to upgrade the Kubernetes version through this role. Actually I am stuck with older version of Kubernetes v1.20.15 and not able to upgrade to the kubernetes version now.

❯ sudo kubeadm upgrade plan

[upgrade/config] Making sure the configuration is correct:
[upgrade/config] Reading configuration from the cluster...
[upgrade/config] FYI: You can look at this config file with 'kubectl -n kube-system get cm kubeadm-config -o yaml'
[upgrade/config] In order to upgrade, a ConfigMap called "kubeadm-config" in the kube-system namespace must exist.
[upgrade/config] Without this information, 'kubeadm upgrade' won't know how to configure your upgraded cluster.

[upgrade/config] Next steps:
        - OPTION 1: Run 'kubeadm config upload from-flags' and specify the same CLI arguments you passed to 'kubeadm init' when you created your control-plane.
        - OPTION 2: Run 'kubeadm config upload from-file' and specify the same config file you passed to 'kubeadm init' when you created your control-plane.
        - OPTION 3: Pass a config file to 'kubeadm upgrade' using the --config flag.

[upgrade/config] FATAL: the ConfigMap "kubeadm-config" in the kube-system namespace used for getting configuration information was not found

❯ sudo kubeadm upgrade plan --config /etc/kubernetes/kubeadm-kubelet-config.yaml

[upgrade/config] Making sure the configuration is correct:

[preflight] If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...`

Any help is appreciated.

At the very least, it would be nice to have documentation around the best way to do upgrades. Kubernetes upgrades are a pain regardless of how automated you can make them.
