Webhook

The webhook Issuer is a generic ACME solver. The actual work is done by an external service. Look at the respective documentation of dns-providers.

View more webhook solvers at https://github.com/topics/cert-manager-webhook.

Here is an example of how webhook providers are to be configured. All DNS01 providers will contain their own specific configuration however all require a groupName and solverName field.

apiVersion: cert-manager.io/v1
kind: Issuer

  name: example-issuer
spec:
  acme:
   ...
    solvers:
    - dns01:
        webhook:
          groupName: $WEBHOOK_GROUP_NAME
          solverName: $WEBHOOK_SOLVER_NAME
          config:
            ...
