Summary

Adds user-facing documentation and sample manifests so new contributors
and testers can deploy the controller and configure agent workloads
without reverse-engineering the codebase.

What's included

Getting-started guide (docs/getting-started.md):

  • Prerequisites (K8s 1.33+, Agent Sandbox)
  • Deploying the controller (make deploy)
  • Creating Gateways with credentials for each provider
  • Creating an Agent and triggering an AgentRun
  • Workflow pointers, local dev, e2e testing, troubleshooting

Sample CRs (config/samples/):

  • gateway_vertex_ai.yaml — GCP Vertex AI with Claude
  • gateway_openai.yaml — OpenAI GPT-4o
  • gateway_anthropic.yaml — Anthropic direct API
  • gateway_aws_bedrock.yaml — AWS Bedrock
  • agent_example.yaml — Java migration agent referencing a gateway and skill
  • agentrun_example.yaml — Triggers the migration agent

Sample CRs are self-contained reference examples with inline
comments explaining prerequisites (e.g. secret creation commands).
They are not added to the samples kustomization since they require
user-specific credentials.

README update: Added a "Getting started" section linking to the
new guide.

Context

From team discussion: multiple people were blocked on testing because
there was no documentation on how to configure things after deploying
the controller. The LLMProvider CRD was renamed to Gateway and
some team members were still on the old version without realizing.

ADR compatibility

Reviewed all open ADR PRs (#108, #106, #138) before writing. The
guide stays at the CRD-level user interface and does not describe
internal delivery mechanisms (params.json, skill loading, ACP
transport) that are in flux. Nothing here contradicts pending
decisions.

📝 Walkthrough

Walkthrough

Added a getting-started guide and README link. Added Gateway samples for four providers. Added migration Agent and AgentRun samples. Updated the AWS Bedrock lifecycle test for Claude Sonnet 4.5.

Changes

Deployment and Agent usage

Layer / File(s) Summary
Gateway configuration samples
config/samples/gateway_*.yaml, harness/internal/goose/lifecycle_test.go
Added Gateway manifests for Anthropic, AWS Bedrock, OpenAI, and Vertex AI. Updated the Bedrock lifecycle test to expect the Claude Sonnet 4.5 model identifier.
Agent and AgentRun samples
config/samples/agent_example.yaml, config/samples/agentrun_example.yaml
Added migration Agent and immutable AgentRun resources with Gateway references, parameters, and execution instructions.
Getting-started workflow
docs/getting-started.md, README.md
Added deployment, Gateway setup, Agent execution, development, testing, cleanup, and troubleshooting instructions. Added a README link to the guide.

Estimated code review effort: 2 (Simple) | ~15 minutes

Mergeability Score: 🟠 High · up to 64273

The guide and samples change how users deploy and configure the product, but several instructions can expose provider credentials, send AWS requests to mismatched regions, leave sample resources referencing an unavailable Gateway, fail on supported Kubernetes versions, or delete unrelated resources during cleanup. These concrete security, destructive-operation, and setup-correctness risks make the PR unsafe to merge until the documentation is corrected.

Checked the samples against api/v1alpha1 and the repo's own scripts — field shapes all match, the Agent Sandbox recipe matches hack/start-kind.sh exactly, and the Makefile targets and kubectl logs $SANDBOX step all check out. Three fixes below, plus CodeRabbit's Anthropic model-ID catch.

This model ID won't resolve on Bedrock. Two things: Bedrock IDs use hyphens (4-5, not 4.5), and Sonnet 4.5 requires an inference-profile prefix rather than on-demand invocation. The string we have working on the ROKS demo cluster is:

    name: us.anthropic.claude-sonnet-4-5-20250929-v1:0

Heads up that the dotted form also appears in harness/internal/goose/lifecycle_test.go:31 — probably where it was copied from, so worth fixing both.

Worth a live check: Vertex uses an @ separator for dated model snapshots (claude-sonnet-4-5@20250929), and the bare alias form is only valid for current-generation models. If goose doesn't normalize this, the run fails at first token.

Minor, same file: endpoint on line 15 has no scheme while the other three samples do. It'd still pass the verification Job's curl, and providerEnv ignores the endpoint entirely for gcp-vertex-ai, so it's cosmetic — but it reads as an inconsistency.

following Options B–D to change both manifests to reference the Gateway they

a clear warning before the make undeploy and make uninstall commands that they
remove CRDs and matching custom resources across namespaces.
- Around line 9-11: Update the Kubernetes prerequisite in the getting-started
documentation to Kubernetes v1.36+ so it matches the stable ImageVolume support
required by corev1.ImageVolumeSource; retain the existing OpenShift and Agent
Sandbox prerequisites.

Avoid exposing provider credentials in command arguments.

When users replace the placeholders, shell history records the secret-bearing commands. Process inspection can also expose the arguments while kubectl runs. Use protected files, stdin-generated Secrets, or an external secret manager.

🛡️ Safer command pattern
 kubectl create secret generic openai-credentials \
-  --from-literal=api-key="<your-openai-api-key>"
+  --from-file=api-key=/secure/path/openai-api-key

Addressed in 521636f. Added a note at the top of the Gateway section recommending --from-file or an external secret manager for anything beyond a throwaway test cluster. Kept --from-literal in the tutorial steps for copy-paste simplicity.

@djzager, the warning is useful. However, the documented OpenAI, Anthropic, and AWS Bedrock commands still use --from-literal with secret values.

A reader who copies the tutorial still exposes credentials through shell history and process arguments. Please change those examples to use --from-file, stdin, or an external secret manager. Keep AWS_REGION as a literal because it is not a secret.

Add docs/getting-started.md with step-by-step instructions for
deploying the controller, configuring LLM credentials, creating
Gateways, Agents, and AgentRuns.

Add sample CRs to config/samples/ for all four supported providers
(Vertex AI, OpenAI, Anthropic, AWS Bedrock), plus an example Agent
and AgentRun that reference the default migration skills.

These are reference examples — not added to the samples kustomization
since they require user-specific credentials.

Update README.md to link to the new getting-started guide.
