Doppler

Doppler is a secrets management tool that has been used extensively with this project.

Development

Running locally

doppler run -- deno run --allow-net --allow-env --allow-read=./src main.ts

Kubernetes

Prerequisites

• Kubernetes cluster with the Doppler operator installed
• A doppler configuration has been created for the environment you are deploying to (in this case we will refer to it as stg but it could be anything)
• A service token has been created for the doppler configuration

Steps

1. Create a new namespace in your cluster for the test

   kubectl create namespace keys-test

2. Create the doppler access token secret Replace dp.st.dev.XXXX with the service token for the target doppler environment

   kubectl create secret generic keys-local-helm-test \
    --namespace doppler-operator-system \
    --from-literal=serviceToken=dp.st.dev.XXXX

3. Create the secret mapping

   kubectl apply -f - <<EOF
   apiVersion: secrets.doppler.com/v1alpha1
   kind: DopplerSecret
   metadata:
     name: local-helm-test
     namespace: doppler-operator-system
   spec:
     tokenSecret:
       name: keys-local-helm-test
     managedSecret:
       name: keys-secret
       namespace: keys-test
       type: Opaque
   EOF

4. The doppler operator should now automatically create a secret called keys-secret. You can confirm this with the following command:

   kubectl describe -n keys-test secret keys-secret

5. You can now deploy the application using helm as documented in the README
