DigitalOcean

This provider uses a Kubernetes Secret resource to work. In the following example, the Secret will have to be named digitalocean-dns and have a sub-key access-token with the token in it. For example:

apiVersion: v1
kind: Secret
metadata:
  name: digitalocean-dns
data:
  # insert your DO access token here
  access-token: "base64 encoded access-token here"

The access token must have write access.

To create a Personal Access Token, see DigitalOcean documentation.

To encode your access token into base64, you can use the following

echo -n 'your-access-token' | base64

apiVersion: cert-manager.io/v1
kind: Issuer
metadata:
  name: example-issuer
