Fiat is the authorization server for the Spinnaker system.

It exposes a RESTful interface for querying the access permissions for a particular user. It currently supports three kinds of resources:

• Accounts
• Applications
• Service Accounts

Accounts are setup within Clouddriver and queried by Fiat for its configured requiredGroupMembership restrictions.

Applications are the combination of config metadata pulled from Front50 and server group names (e.g., application-stack-details). Application permissions sit beside application configuration in S3/Google Cloud Storage.

Fiat Service Accounts are groups that act as a user during automated triggers (say, from a GitHub push or Jenkins build). Authorization is built in by making the service account a member of a group specified in requiredGroupMembership.

Currently supported user role providers are:

• Google Groups (through a Google Apps for Work organization)
• GitHub Teams
• LDAP
• File based role provider

By default, Fiat is built with all authorization providers included. To build only a subset of providers, use the includeProviders flag:

./gradlew -PincludeProviders=google-groups,ldap clean build

You can view the list of all providers in gradle.properties.

To start the JVM in debug mode, set the Java system property DEBUG=true:

./gradlew -DDEBUG=true

The JVM will then listen for a debugger to be attached on port 7103. The JVM will not wait for the debugger to be attached before starting Fiat; the relevant JVM arguments can be seen and modified as needed in build.gradle.
