We need to completely remove Kubernetes from Ubuntu 18.04 server.
For that we tried
kubeadm reset
sudo apt-get purge kubeadm kubectl kubelet kubernetes-cni kube*
It gives
Package 'kubeadm' is not installed, so not removed
Package 'kubectl' is not installed, so not removed
Package 'kubelet' is not installed, so not removed
Package 'kubernetes-cni' is not installed, so not removed
If we run kubeadm version
kubeadm version: &version.Info{Major:"1", Minor:"21", GitVersion:"v1.21.3", GitCommit:"ca643a4d1f7bfe34773c74f79527be4afd95bf39", GitTreeState:"clean", BuildDate:"2021-07-15T21:03:28Z", GoVersion:"go1.16.6", Compiler:"gc", Platform:"linux/amd64"}
which kubeadm
/usr/local/bin/kubeadm
dpkg -S /usr/local/bin/kubeadm
dpkg-query: no path found matching pattern /usr/local/bin/kubeadm
snap list --all
No snaps are installed yet. Try 'snap install hello-world'
We had installed Kubernetes using no source compiling locally.
curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key
add
sudo apt-add-repository "deb http://apt.kubernetes.io/ kubernetes-xenial main"
sudo apt update
sudo apt install kubeadm kubelet kubectl
sudo apt-mark hold kubeadm kubelet kubectl
What is the issue here? How can I properly remove Kubernetes from this node?
kubeadm resetsettings are removed (however some traces can be left). There are different options what can be done withbrokenpackages, e.g. try with dpkg or other options from this answer or I've seen it's possible to install them and then remove properly. Also! Sounds obvious, but nowadays it's much faster to recreate a VM.
