service-ca-operator CLAUDE.md

service-ca-operator CLAUDE.md is an instructions file for coding agents from openshift/service-ca-operator. It costs 1,546 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for OpenShift's service-ca-operator, which manages an internal certificate authority and TLS certificates for services in a Kubernetes cluster.

In plain words
What is it for?
Use them when building the operator, running or selecting Go tests, testing with a cluster, checking generated files, or updating dependencies.
Why use it?
They give the exact build, unit-test, end-to-end test, verification, generation, and dependency commands, plus an overview of the operator's two processes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

service-ca-operator CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Architecture

This is an OpenShift ClusterOperator with a two-process architecture running from a single binary (service-ca-operator):

Operator Process (service-ca-operator operator)

  • Package: pkg/operator/
  • Has two main responsibilities:
    1. Operand lifecycle: Manages the controller Deployment in the openshift-service-ca namespace, syncing static resources (namespace, service account, RBAC, deployment) from embedded assets
    2. Signing CA management: Creates and rotates the signing CA keypair (Secret) and maintains the CA bundle ConfigMap
  • Reports the "service-ca" ClusterOperator status conditions

Controller Process (service-ca-operator controller)

  • Package: pkg/controller/
  • Started by the operator as a Deployment; runs three controllers:
    1. Serving Cert Signer (pkg/controller/servingcert/): Signs TLS serving certs for Services annotated with service.beta.openshift.io/serving-cert-secret-name
    2. ConfigMap CA Bundle Injector (pkg/controller/cabundleinjector/configmap.go): Injects the CA bundle into ConfigMaps annotated with service.beta.openshift.io/inject-cabundle=true
    3. Generic CA Bundle Injector (pkg/controller/cabundleinjector/): Injects the CA bundle into APIServices, MutatingWebhookConfigurations, ValidatingWebhookConfigurations, and CRDs with the same annotation

Embedded Assets

Static resource manifests are embedded using Go's native embed.FS:

  • Asset location: bindata/assets/*.yaml
  • Embed declaration: bindata/assets.go (uses //go:embed assets/*.yaml)
  • Usage: bindata.MustAsset("assets/<filename>.yaml") to read asset bytes at runtime
  • No code generation step is required — assets are embedded at compile time

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
