I do not mean it in a bad way and I understand this can be overwritten:), but I believe the introduction of the OpenStackAssistant feature as it is can be detrimental to the feedback gathering mechanism currently in place for OpenStack Lightspeed.
As of now, there is no mechanism in place that can differentiate transcripts gathered from the goose part and the OpenStackLightspeed part. If both the goose part and the OpenStackLightspeed part are deployed in an environment, then both transcripts get mixed up, and at the end of the transcript gathering pipeline, it won't be possible for us to distinguish between them. It will be hard for us to find lessons to be learned for both OpenStackLightspeed and the OpenStackAssistant.
I believe we should find a way how to resolve this nicely.
Would it be reasonable to file your suggestion as a new feature and work on it separately? This PR is already quite large and implements the basis of a CLI. In the meantime if a user really wanted isolated transcripts they could deploy 2 separate OpenStackLightspeed stacks and approach it that way as well. |

@dprince I did a little investigation today and I have to admit I need to tone down my concerns a bit. Sorry about that. I still think the transcript/feedback gathering story is something we should look at, but it is less urgent (blocking) than I initially thought.
This resolves my main concern -> that transcripts from OpenStack Lightspeed and Goose would be mixed together. Since Goose skips transcripts gathering entirely ( [1] https://github.com/lightspeed-core/lightspeed-stack/blob/main/src/app/endpoints/responses.py#L302 The transcript and feedback gathering feature would probably require (as already discussed + additional new things based on the investigation)
No. 1. and no 2. gets as to the point where we are collecting transcripts and feedback but then we face this problem:

Introduces a new OpenStackAssistant custom resource (assistant.openstack.org/v1beta1) that deploys a managed Goose AI agent pod for cluster diagnostics via Lightspeed Stack. OpenStackAssistant CRD and controller: - New CRD with spec fields for provider type, container image, Lightspeed Stack backend configuration, node selectors, and additional environment variables - GooseConfig supports model selection, recipe ConfigMaps (registered as Goose slash commands), hints ConfigMaps (written to .goosehints), and MCP server references - Controller creates a ServiceAccount, ClusterRole with read-only RBAC for cluster diagnostics, ClusterRoleBinding, ConfigMap with Goose configuration and entrypoint script, and the assistant Pod - Watches referenced Secrets and ConfigMaps; reconciles on changes and tracks input hashes to detect drift - Defaulting webhook sets the container image from an environment variable fallback - Condition-based status reporting (ServiceAccount, RBAC, ConfigMap, Pod readiness) MCP server sidecar support for OpenStackClient: - New MCPConfig struct (enabled flag, containerImage) on the OpenStackClient CR spec - When enabled, the OpenStackClient controller adds a rhos-mcps MCP server sidecar container sharing the same clouds.yaml/secure.yaml credential mounts - Controller creates a ConfigMap with rhos-mcps config (openstack enabled, openshift disabled, allow_write: false) and a Service on port 8080 for the MCP endpoint - OpenStackAssistant can reference an OpenStackClient CR by name via the openstackClientRef field; the controller auto-computes the service URL and TLS CA configuration Tests: - Unit tests for the OpenStackAssistant controller covering reconciliation, pod creation, config generation, and status conditions - Unit tests for helper functions (entrypoint script generation, config building, hash computation) 44 files changed, ~4,300 lines added.

The MCP server sidecar on the OpenStackClient pod is exposed via a ClusterIP Service with no caller authentication, so any pod that could resolve its DNS name — in any namespace — could reach it. Add a NetworkPolicy, generated per OpenStackClient instance alongside the existing MCP Service, that only allows ingress on port 8080 from OpenStackAssistant pods in the same namespace. Also add support for skills to the assistant

Estimated code review effort: 5 (Critical) | ~120 minutes
Merge Risk: 🟠 High · up to f7a15
The new assistant and MCP support can fail to start in the default configuration, reject the bundled sample, lose TLS connectivity or retain stale MCP resources, and deploy changing images or overly broad authorization permissions. These issues can leave diagnostics unavailable and increase security and deployment risk, so the PR should not merge until the concrete problems are fixed or explicitly accepted.

Pin the fallback assistant image to a digest.
When RELATED_IMAGE_OPENSTACK_ASSISTANT_IMAGE_URL_DEFAULT is unset, SetupDefaults uses quay.io/dprince/goose:oc-fedora. This mutable tag can change the deployed agent image without an operator release. Use the approved immutable image digest for this fallback.

Enforce the MCP server reference and name contract at admission.
MCPServerRef currently allows both endpoint fields or neither, so an entry can be ambiguous or silently omitted. Names containing characters such as - are also converted into invalid environment-variable names, preventing pod creation. Require exactly one of url or openstackClientRef, and reject or normalize names to a Kubernetes-compatible form in the API schema.

Clear the MCP image when the source is removed.
When version.Status.ContainerImages.OpenstackMcpImage becomes nil, this callback leaves openstackclient.Spec.MCPContainerImage unchanged. CreateOrPatch retains the existing object, so the previous image can remain in the persisted spec and keep the MCP sidecar configured. Clear the field to its zero value when the source image is nil.

Guard SSL_CERT_FILE against set -u.
The script runs with set -eu. Line 144 expands $SSL_CERT_FILE without a default. SSL_CERT_FILE is only exported at line 132 when service-ca.crt exists, or through the container env when hasCombinedCA is true or LightspeedStack.CaBundleSecretName is set. In the default configuration (no combined CA, no CA bundle secret, no service-ca.crt) the variable is unset, so set -u aborts the script with SSL_CERT_FILE: unbound variable and the pod never reaches exec sleep infinity.

Narrow allowed_hosts and allowed_origins, or record why the wildcards are safe.
The config sets enable_dns_rebinding_protection: false with allowed_hosts: ["*:*"] and wildcard origins. These three settings together remove the MCP transport security checks. The NetworkPolicy limits which pods can connect, so this is defense in depth rather than an open path. Restrict the values to the MCP Service hostname, for example <name>-mcp.<namespace>.svc:8080, so a compromised assistant pod cannot use the server as a rebinding target.
