[LINUX] Build a Kubernetes environment for development on Ubuntu
Kubernetes Explainer Video
On our YouTube channel, we have released a video explaining Kubernetes by CTO @bunchan_k.
I am also studying with this video, but since the procedure for building the Kubernetes environment of Ubuntu was not described, I practiced it with reference to the official documents and summarized it.
Install kubectl
You can either install the binaries or install them from your package manager. I decided to use the package manager (apt) to make it easier to update the version.
sudo apt-get update && sudo apt-get install -y apt-transport-https
curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee -a /etc/apt/sources.list.d/kubernetes.list
sudo apt-get update
sudo apt-get install -y kubectl
I haven't tried it, but it can be installed with snap.

installation of minikube
You need to install kubectl in advance.
About hypervisor installation
Usually, you need a hypervisor environment that runs Kubernetes, such as KVM or VirtualBox.
Minikube also supports the --vm-driver = none option to run Kubernetes components on the host instead of the VM. You need Docker and a Linux environment to use this driver, but you don't need a hypervisor.
Since it is as above, Docker is also installed on my Ubuntu, so I will not use the hypervisor.
Installing minikube from Linux Homebrew
There are several methods, such as binary installation and package installation. In particular, it seemed easy to install from Linux Homebrew, so I will do it here.
Install Linux Homebrew
The procedure is the same as for mac.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Leave it through the path.
echo 'eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)' >> /home/takaken/.bash_profile
installation of minikube
brew install minikube
That's it!
Afterword
I was able to build a Kubernetes environment for development on Ubuntu. If you are using another Linux distribution, you can build it by the same procedure if you read the package management.
From now on, I plan to study how to run Lavavel and Node apps on K8s by referring to the video.
