Create secret

To create such a Kubernetes secret first get base64 encoded value of the certificate.

cat .ca/c2/c2.crt | base64 -w 0 > /tmp/secret.txt

Create YAML file for example cert.yml 

apiVersion: v1
kind: Secret
metadata:
  name: c2-root-cert
data:
  c2.crt: <base64-encoded certificate text>

Create the secret in namespace kube-system so it can be used by all pods in the cluster.

vagrant ssh c2d-ks1
kubectl config set-context --current --namespace=kube-system
kubectl apply -f /vagrant/doc/howto-kubernetes-cert/c2-cert.yml
Show me
vagrant@c2d-ks1:~/scripts/microk8s/gitlab/gitlab-runner$ kubectl get secrets
