The OPA onboarding process starts with defining what you want to enforce. Map the resources, actions, and identities that matter. Write them down before touching code. This step makes every later decision faster and cleaner.
Next, install OPA in the environment where it will run. You can deploy it as a sidecar, a daemon, or in Kubernetes. Keep it close to the services making authorization decisions. The onboarding workflow here is to integrate OPA early—before writing complex policies—so you can test basic queries.
Learn Rego, OPA’s policy language. Your onboarding should introduce Rego with simple examples: allow, deny, based on user roles or request attributes. Store policies in version control. Make updates part of your CI/CD pipeline. This keeps the onboarding process tied directly to your engineering workflow.
Configure data loading. OPA works best when it has all the context it needs—user details, resource metadata, external API responses—right at decision time. During onboarding, set up secure data feeds or bundles to sync this information. Test frequently to ensure OPA sees accurate, timely data.
