Add a lightweight CI step that sends deploy context to your tenant and gets an allow, warn, or deny decision back without self-hosting OPA.

Destinatari: Platform engineers, release managers, and security engineersTempo stimato: 10 minutes

Prima di iniziare

  • Install the managed starter pack in Policies and keep it in advisory mode for the first rollout.
  • Choose an enforcement point in Policies → Settings; the wizard creates the scoped credential.
  • Identify the service ID, target environment, artifact name, and branch values your deploy pipeline already exposes.

Passo 1

Install the managed starter pack in the tenant

Open the Policies console, keep the starter pack in advisory mode first, and tune thresholds before enforcing production blocks.

  • Open Policies in the dashboard and review Starter Deploy Guardrails.
  • Confirm environments, severity thresholds, freshness window, and fail-open or fail-closed behavior.
  • Run a simulation with a representative production payload before wiring CI.
  • Save at least one assertion and run all tests against the exact draft before publication.
  • Tenant Rego runs in disposable workers with source/test-size, timeout, memory, and concurrency limits.

Passo 2

Connect an enforcement point

Use the managed integration wizard to create a ten-minute single-use bootstrap token. Its command creates and stores a policies:read key without exposing it in browser state or shell history.

  • Choose GitHub Actions, GitLab CI, Kubernetes admission, or generic REST in Policies → Settings.
  • Run the generated command on a machine where gh, glab, or kubectl is already authenticated.
  • Map service, environment, branch, artifact, and actor metadata from your pipeline variables.
  • Start with advisory rollout mode so warn outcomes surface without blocking releases.

Passo 3

Add the policy client job to your deploy pipeline

Run the policy client before the real deployment step. It posts the deploy request, prints reasons, and exits non-zero only when the final decision is deny.

  • Bootstrap the GitHub Actions or GitLab source bundle from this guide, then commit it to your repo.
  • Set `POLICY_SERVICE_ID`, `POLICY_TARGET_ENVIRONMENT`, and any optional repository or artifact fields.
  • Pass reviewer, ticket, or promotion metadata through `POLICY_CONTEXT_JSON` when your tenant policies expect it.
  • Place the job immediately before the production deploy so the decision reflects the current release candidate.

Criteri di successo

Place the job immediately before the production deploy so the decision reflects the current release candidate.

Deploy the Pipeline Scanner

Criteri di successo

  • The policy client returns `allow` or `warn` for a healthy sample deploy and exits with code 0.
  • A seeded or simulated high-risk release returns `deny` and blocks the deploy stage with clear reasons.
  • Decision history in Policies records the request summary, matched policies, and final outcome.

Continua

Keep your rollout moving with the next recommended step.
