Deploy a management cluster into kind and a workload cluster using the CAPD provider and flux.
- install clusterctl
- install kind
- install kubectl
- install docker
- install fluxctl
Run the following commands in yoru terminal:
cat > kind-cluster-with-extramounts.yaml <<EOF
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
extraMounts:
- hostPath: /var/run/docker.sock
containerPath: /var/run/docker.sock
EOF
Apply this config:
kind create cluster --image kindest/node:v1.23.1 --config kind-cluster-with-extramounts.yaml
Initialize the management cluster:
# Initialize the management cluster
clusterctl init --infrastructure docker
Wait for it to complete (you should see the following message):
Your management cluster has been initialized successfully!
You can now create your first workload cluster by running the following:
clusterctl generate cluster [name] --kubernetes-version [version] | kubectl apply -f -
The CAPI cluster resources have already been generated here. Lets deploy flux to the cluster and let that manage the install.
To do this though, yoiu cna run this command:
clusterctl generate cluster capi-quickstart --flavor development \
--kubernetes-version v1.23.1 \
--control-plane-machine-count=1 \
--worker-machine-count=1 \
> ./clusters/my-cluster/capi-quickstart.yaml
Deploy flux to the cluster:
export GITHUB_TOKEN=<add github token here>
export GITHUB_USER=<add github username here>
flux bootstrap github \
--owner=$GITHUB_USER \
--repository=capi-docker-dev \
--branch=main \
--path=./clusters/my-cluster \
--personal
Wait for the workload cluster deployment to complete:
kubectl get kubeadmcontrolplane -A --watch
Once initialized, get the workload kubeconfig:
clusterctl get kubeconfig capi-quickstart > capi-quickstart.kubeconfig
When using using Docker Desktop on macOS or Docker Desktop (Docker Engine works fine) on Linux, you’ll need to take a few extra steps to get the kubeconfig for a workload cluster created with the Docker provider.
# Point the kubeconfig to the exposed port of the load balancer, rather than the inaccessible container IP.
sed -i -e "s/server:.*/server: https:\/\/$(docker port capi-quickstart-lb 6443/tcp | sed "s/0.0.0.0/127.0.0.1/")/g" ./capi-quickstart.kubeconfig
