Configure client custom SSL certificate

1. Have your private key and certificate in the PEM format (e.g. openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -days 365 -out certificate.pem) and create a file called custom_cert.yaml anywhere inside the cluster with the following content:

   apiVersion: v1
   kind: Secret
   metadata:
     name: custom-default-cert
     namespace: kube-system
   type: kubernetes.io/tls
   data:
     tls.crt: $CERTIFICATE_BASE64
     tls.key: $PRIVATE_KEY_BASE64
   ---
   apiVersion: traefik.containo.us/v1alpha1
   kind: TLSStore
   metadata:
     name: default
     namespace: kube-system
   spec:
     defaultCertificate:
       secretName: custom-default-cert

   1. Replace $CERTIFICATE_BASE64 with the base64 encoded content of your certificate (e.g. cat certificate.pem | base64)

   2. Replace $PRIVATE_KEY_BASE64 with the base64 encoded content of your private key (e.g. cat key.pem | base64)

2. Run kubectl apply -f custom_cert.yaml
