k3d cluster deploy

Create docker network

#!/usr/bin/env pwsh
docker network create `
  --driver=bridge `
  --subnet=172.28.0.0/16 `
  --ip-range=172.28.5.0/24 `
  k3d

#!/usr/bin/env bash
docker network create \
  --driver=bridge \
  --subnet=172.28.0.0/16 \
  --ip-range=172.28.5.0/24 \
  k3d

Deploy cluster

#!/usr/bin/env pwsh
k3d cluster create `
  --network k3d `
  --servers 2 `
  --agents 3 `
  --no-lb `
  --k3s-arg "--disable=traefik@servers:0" `
  --k3s-arg "--disable=traefik@servers:1" `
  --k3s-arg "--disable=servicelb@servers:0" `
  --k3s-arg "--disable=servicelb@servers:1"

#!/usr/bin/env bash
k3d cluster create \
  --network k3d \
  --servers 2 \
  --agents 3 \
  --no-lb \
  --k3s-arg "--disable=traefik@servers:0" \
  --k3s-arg "--disable=traefik@servers:1" \
  --k3s-arg "--disable=servicelb@servers:0" \
  --k3s-arg "--disable=servicelb@servers:1"

Get cluster config

cp $(k3d kubeconfig write) ./.kube/config

Now start devcontainer

In VScode:

> Dev Containers: Reopen in Contsainer

Check cluster

kubectl get nodes

The command output (like this):
