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.


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.

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.

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

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.

Then I installed K9S by running curl -sS | bash and this was the output:

[terminator@skynet ~]$ curl -sS | bash

Thanks for using webi to install 'k9s@stable' on 'Linux/6.4.15-200.fc38.x86_64/x86_64'.
Have a problem? Experience a bug? Please let us know:

Lovin' it? Say thanks with a Star on GitHub:
