Secrets with S3
This document describes how to set up Spinnaker secrets in an encrypted S3 bucket. See the S3 Getting Started Guide for more information on encryption in S3.
This example uses a bucket (
mybucket) in the
us-west-2 region to store GitHub credentials and a kubeconfig file. You reference the bucket by its URL
Since you’re storing sensitive information, make sure to protect the bucket by restricting access and enabling encryption.
Remember to run the Operator (or Halyard’s daemon) and Spinnaker services with IAM roles that allow them to read the keys stored in the AWS S3 Bucket.
Store your GitHub credentials in
github: password: <PASSWORD> token: <TOKEN>
Note: You could choose to store the password under different keys than
github.token. You’d just need to change how to reference the secret further down.
Storing sensitive files
Some Spinnaker configuration uses information stored as files. For example, upload the
kubeconfig file of your Kubernetes account directly to
aws s3 cp /path/to/mykubeconfig s3://mybucket/mykubeconfig
Now that secrets are safely stored in the bucket, you reference them from your config files with the following format. The S3 specific parameters (
b:<bucket>, etc) can be in any order:
encrypted:s3!r:<region>!b:<bucket>!f:<path to file>!k:<optional yaml key>
For example, to reference
github.password from the file above, we’ll use:
And to reference the content of our kubeconfig file:
