Use Exoscale ClusterAPI

Prerequisite

• https://github.com/exoscale/cluster-api-provider-exoscale#prerequisite

Create bootstrap cluster

Use an existing k8s cluster or bootstrap it

With kind:

% kind create cluster --name=clusterapi

% export KUBECONFIG="$(kind get kubeconfig-path --name="clusterapi")"

Deploy custom resources

Configuration is done via the following environement variables.

export EXOSCALE_API_KEY=EXO...
export EXOSCALE_SECRET_KEY=...
export EXOSCALE_COMPUTE_ENDPOINT=https://api.exoscale.com/compute

run make

% kubectl --kubeconfig=$KUBECONFIG \
            apply -f \
            provider-components.yaml

You can use the kubeconfig of your bootstrap cluster, $KUBECONFIG in our case with kind

Deploy your cluster

use cluster.yaml and machine.yaml in the repo:

• cmd/clusterctl/examples/exoscale/

% kubectl --kubeconfig=$KUBECONFIG \
            create -f \
            cmd/clusterctl/examples/exoscale/cluster.yaml

% kubectl --kubeconfig=$KUBECONFIG \
            create -f \
            cmd/clusterctl/examples/exoscale/machine.yaml

Follow the cluster bootstrap.

% kubectl --kubeconfig=$KUBECONFIG \
            logs -f -n exoscale-provider-system \
            exoscale-provider-controllers-...

have a look to your new cluster

Get your new kubeconfigfrom the new bootstrapped cluster

% ./bin/clusterctl --kubeconfig=$KUBECONFIG  \
             alpha phases  \
             get-kubeconfig \
             --provider exoscale \
             --cluster-name my-exoscale-cluster \
             --kubeconfig-out kubeconfig-newcluster

% kubectl --kubeconfig kubeconfig-newcluster get nodes
