## Mounting CA Certificates on kind

If you need to mount custom CA certificates into the kind cluster, follow the steps below:

Modify your kind cluster configuration file (cluster.yaml) to include the CA certificate mount:

```

kind: Cluster

apiVersion: kind.x-k8s.io/v1alpha4

nodes:

  - role: control-plane

    extraMounts:

      - hostPath: /path/to/your/ca-certificate.crt

        containerPath: /path/to/your/ca-certificate.crt

```

Once the cluster is up, you need to update the CA certificates inside the kind nodes. Run the following script:

```

CERT=/path/to/your/ca-certificate.crt

CLUSTER=oop-cluster

kind get nodes --name "$CLUSTER" | while read -r n; do

  echo "==> Configuring CA on $n"

  docker exec "$n" sh -lc "

    set -e

    test -f $CERT || { echo 'CA cert not found'; exit 1; }

    update-ca-certificates

    systemctl restart containerd

    systemctl restart kubelet

    echo 'CA trust updated'

  "

done

```
