learning kubernetes

a repo created in order to learn the basics of kubernetes with my personal notes

Kubernetes is an open-source container-orchestration system for automating application deployment, scaling, and management.

Reference materials: https://cloudowski.com/kubernetes-po-polsku/ [PL]

installation

sudo pacman -S minikube
sudo pacman -S kubectl

overview:

• minikube is local instance of kubernetess cluster running as VM in VirtualBox
• kubectl is kube controller used for controlling things inside kubernetess cluster

requirements for minikube (arch linux specific):

sudo pacman -S virualbox
sudo pacman -S virtualbox-host-modules-arch
sudo modprobe vboxdr
sudo modprobe vboxnetadp
sudo modprobe cboxnetflt
sudo /sbin/rcvboxdrv setup

note: not all the things above are probably required, but I had to play around with VirtualBox in order to make minikube work on arch linux

basic commands:

• minikube start starts the cluster
• minikube stop stops the cluster
• minikube dashboard opens dashboard in the web browser
• minikube shows help
• kubectl shows help
• VBoxManage list runningvms show running VMs
• VBoxManage list vms shows all VMs
