Secrets in Google Secret Manager

This document describes how to set up Spinnaker secrets in a Google Secret Manager.

This example uses secrets - mysecret1, mysecret2 - to store GitHub credentials and secret - mykubeconfig - to store kubeconfig file.


Since you’re storing sensitive information you protect the secret by restricting access to it through IAM roles . Encryption at rest is already provided by default.

Remember to run Halyard’s daemon and Spinnaker services with a service account that allows them to read that content.

Storing secrets

Storing credentials

Store your GitHub token in a secret named mysecret either as a complete secret or as a value of one of the json keys:

  • secret mysecret1:
  • secret mysecret2:
      "github-token": "<TOKEN>",
      "some-other-key": "<some-other-secret>"

Note: You could choose to store the token under different key than github-token. You’d just need to change how to reference the secret .

Storing sensitive files

Some Spinnaker configuration uses information stored as files. For example, upload the kubeconfig file of your Kubernetes account directly to mykubeconfig secret:

gcloud secrets versions add mykubeconfig --data-file="/path/to/kubeconfig"

Referencing secrets

Now that secrets are safely stored in the Secret Manager, you reference them from your config files using the format below. The Secret Manager specific parameters (p:<project number>, s:<secret id>, k:<optional json key>, v:<optional secret version>) can be in any order. To reference secret literal values:

encrypted:google-secrets-manager!p:<project number>!s:<secret id>!k:<optional json key>!v:<optional secret version>

To reference secret files:

encryptedFile:google-secrets-manager!p:<project number>!s:<secret id>!v:<optional secret version>

To reference the latest version of secret from mysecret1, use:


The k:<key> parameter is only necessary when storing secret values in a json file. Also, the v:<secret version> parameter is required only when the secret is not from the latest version. To reference github-token from the secret above having version 2, use:


But to reference your kubeconfig file, you must leave off the k parameter and use encryptedFile prefix:
