paas-secrets-buildpack

CloudFoundry buildpack used by apps to get secrets out of Vault and in to environment variables.

Usage

---
NOTIFY_API_KEY: "$ORG_PATH/notify:api_key"
AWS_ACCESS_KEY_ID: "$APP_GUID_PATH/aws:AWS_ACCESS_KEY_ID"
AWS_SECRET_ACCESS_KEY: "$APP_GUID_PATH/aws:AWS_SECRET_ACCESS_KEY"

Add an app-secrets.yml file to the root of your app. It describes which environment variables should hold which secret value.

To map a particular secret value, provide its path, a colon, and the key within that secret. For example: path/to/secret:key.

Placeholders

Paths for secrets in GOV.UK PaaS always the org guid of the org, and can also contain the space and app guids. Since they cannot be known at development time, the buildpack provides a number of placeholders that get substituted at runtime.

Secret paths can contain a number of placeholders, which are substituted when the app starts up

  • $ORG_PATH path to the org level secrets using the org guid, without a trailing slash e.g. /cloudfoundry/orgs/guid-123
  • $SPACE_PATH path to space level secrets using the space guid, without a trailing slash e.g. /cloudfoundry/orgs/guid-123/spaces/guid-456
  • $APP_GUID_PATH path to the app level secrets using the guid, without a trailing slash e.g. /cloudfoundry/orgs/guid-123/spaces/guid-456/apps/guid-789
  • $APP_NAME_PATH path to the app level secrets using the name, without a trailing slash e.g. /cloudfoundry/orgs/guid-123/spaces/guid-456/apps/app-name

Why not secrets.yml?

Ruby on Rails got there first.
