Kubernetes - how to create a DEV instance?

WARNING : Like docker, a local Kubernetes installer may create many virtual networks (see ip link). You may use a VM to avoid IP conflict with school/enterprise network.

Using local installers

• kind (Kubernetes in docker)

See docker-devbox - kind folder providing kind/quickstart.sh script to start a kind cluster with an ingress controller, network policy supports, a dashboard,...

• K3S comes with an easy setup for a single node cluster

See mborne/vagrantbox and mborne/k3s-deploy to create a K3S cluster with multiple nodes using Vagrant and Ansible.

• Note that alternatives (k3s, microk8s, minikube,...) exists

See landscape.cncf.io - Certified Kubernetes - Distribution and thechief.io - K3d vs k3s vs Kind vs Microk8s vs Minikube

Managed Kubernetes

Note that it is sometimes to use free credits or student accounts to create Kubernetes clusters managed by cloud providers like :

• Google Kubernetes Engine (GKE)

See mborne/gke-playground aiming at quickly provisioning a GKE cluster with Terraform.

• OVH - Managed Kubernetes Services (MKS)

See Creating a cluster through Terraform

• Note that alternatives like AKS, EKS,... exists :

See landscape.cncf.io - Certified Kubernetes - Hosted
