Method 1 (didn't work for me):
Here is the command:
sudo dnf install kubernetes etcd
The console output should be similar to this:
[terminator@skynet ~]$ sudo dnf install kubernetes etcd

Here are the services that need to be enabled:
sudo systemctl enable --now etcd
sudo systemctl enable --now kube-apiserver
sudo systemctl enable --now kube-controller-manager
sudo systemctl enable --now kube-scheduler
sudo systemctl enable --now kubelet
sudo systemctl enable --now kube-proxy
sudo systemctl enable --now docker
Check status:
sudo systemctl status etcd
sudo systemctl status kube-apiserver
sudo systemctl status kube-controller-manager
sudo systemctl status kube-scheduler
sudo systemctl status kubelet
sudo systemctl status kube-proxy
sudo systemctl status docker
For me two things did not work after all this "easy" installation process:
- kube-apiserver
- kubelet
Of course, life is not easy. While others install it flawlessly I am always chosen to go through suffering and pain in order to learn and become stronger.
I decided to uninstall the shit by running sudo dnf uninstall kubernetes etcd and try another method.
Sources:
Method 2 (didn't work for me):
I created Kubernetes repo inside YUM repos directory:
sudo nano /etc/yum.repos.d/kubernetes.repo
I added the following content, then saved and exited.
[kubernetes]
name=Kubernetes
baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=1
repo_gpgcheck=0 #NOTE: This was originally 1 but I set it to 0 to avoid yet another stupid error! It only skips the GPG check, no big deal.
gpgkey=https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg
I then ran sudo yum install -y kubectl to install Kubernetes (apparently).
The thing worked (apparently):

However of course it had to be wrong!
[terminator@skynet yum.repos.d]$ kubectl cluster-info

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
The connection to the server localhost:8080 was refused - did you specify the right host or port?
So again I ran sudo yum remove kubectl to get out of the shit! (again).
Method 3 (worked for me):
So becuase luck seemed to never be on my side I decided to try both methods at the same time Method 1 and Method 2.
The result was the same, nothing was running well (as far as my understanding went) but this time I tried something different. After a lot of reading on the Internet and several minutes of reflection I realized that mayvbe everything was installed but not configured, I had a strong suspicion that something else was left to install/configure.
I decided to install minikube by running:
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube
This made a big difference becuase it configured kubectl to work with
minikube cluster and the default namespace by default.
Here's the output:
[terminator@skynet ~]$ minikube start
😄 minikube v1.31.2 on Fedora 38 (vbox/amd64)
✨ Automatically selected the qemu2 driver. Other choices: none, ssh
🌐 Automatically selected the builtin network
❗ You are using the QEMU driver without a dedicated network, which doesn't support `minikube service` & `minikube tunnel` commands.
