Requirements

Homebrew should be installed, if not look here

Packages

Use homebrew to install some of the fundamantels

brew install podman minikube kubectl k9s octant

The installed tools are:

  • podman => docker alternative website
  • minikube => local kunbernetes development environment website
  • kubectl => kubernetes commandline
  • k9s => terminal based kubernetes GUI website
  • octant => electron based kubernetes GUI website

The GUI tools are a work in Progress, which one feels better or if everything will be kubectl aliases.

Prerequisites - Podman

Starting and initializing podman

# Initialise podman
# minikube wants at least 2 CPUS
# minikube wants at least 2 GB RAM
podman machine init --cpus 4 --memory 8192
# creating the VM
podman machine start
#
# verify
podman info

Prerequisites - minikube

Configure minikube to work with podman. A detailed explanation can be found here

# configure minikube to use podman
minikube config set driver podman
# configure minikube to use containerd as container runtime
minikube config set container-runtime containerd
# configure minikube to use rootless podman
minikube config set rootless true
# start minikube
minikube start

Cluster check

Now a cluster should be starting. you can check on it with the following commands:

➜  ~ podman info
host:
  arch: arm64
  buildahVersion: 1.26.1
  cgroupControllers:
...

  APIVersion: 4.1.1
  Built: 1658516809

➜  ~ minikube status
minikube
type: Control Plane
host: Running
kubelet: Running
apiserver: Running
kubeconfig: Configured

➜  ~ kubectl cluster-info
Kubernetes control plane is running at https://127.0.0.1:41193
CoreDNS is running at https://127.0.0.1:41193/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
