Deploy in a Google Cloud Function

You can deploy the webhook to a Google cloud function using the following steps:

  1. Clone this repository and make it your working directory:
    git clone && cd secrethub-kubernetes-mutating-webhook
  2. Deploy the webhook to a Google Cloud Function:
    gcloud functions deploy secrethub-mutating-webhook --runtime go113 --entry-point F --trigger-http --allow-unauthenticated

    The function is configured to allow unauthenticated requests. The function doesn’t give access to any resources or data. It only allows you to mutate provided data.

  3. Set the Google Cloud Function URL in the deploy.yaml:
    URL=$(gcloud functions describe secrethub-mutating-webhook --format 'value(httpsTrigger.url)') sed -i "s|YOUR_CLOUD_FUNCTION_URL|$URL|" deploy/gcloud-function/config.yaml
  4. Enable the webhook on your Kubernetes cluster:
    kubectl apply -f deploy/gcloud-function
