We used to be able to change the RAG image using the ragImage
field in our CR, but we removed it and said we would make a consistent
interface to modify ALL possible images via the CRD.

In this PR we add functionality to change the images used by the
operator for the following:

  • lighspeed-core
  • OGX / llama-stack
  • exporter
  • postgres
  • console
  • OKP
  • RHOS MCP server
  • RAG

As agreed instead of having a single location for all the images we create different groups for the different elements of the application.

In each of this sections we have their configuration options, such as:

  • Resource limits
  • Logging configuration
  • Container image override

This also helps with functionality with configuration options still living in the dev section (like the rhoso mcp) as the container image change does not need to be exposed in a top level image changing section.

The name of the image field is imageContainer for consistency with other openstack-k8s-operators.

To keep the CRD consistent we allow overriding the OGX and Lightspeed container images separately, which is a change from the current behavior that forced them to have the same image.

As part of this we add a new environmental variable for OGX, named RELATED_IMAGE_OGX_IMAGE_URL_DEFAULT.

Now lightspeed and OGX have the same initial default, but they are not tied together, so changing the lightspeed image (via env vars or CR) will not make OGX use the same image.

Jira: OSPRH-34773

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository. I understand the commands that are listed here.

Instead of having a section for the logs and a section for the resource
limits we start having sections for different compoments like other
OpenStack Operators do.

The new groupings are:

- lightspeed
- ogx
- database
- okp
- console
- dataverseExporter

Within the `dev` section we change the `rhosMCP` field so we can hold
both the YAML configuration override and the resource limit.

📝 Walkthrough

Walkthrough

The API now supports per-component resources, log levels, feedback settings, RHOS MCP configuration, and container image overrides. Controllers consume the new fields, and CRD, documentation, unit tests, and KUTTL tests reflect the updated configuration structure.

Changes

Component configuration

Layer / File(s) Summary
API contracts and generated support
api/v1beta1/openstacklightspeed_types.go, api/v1beta1/zz_generated.deepcopy.go, config/crd/*, config/manifests/*
The API defines component-scoped configuration, structured rhosMCP, OGX defaults, and matching deepcopy methods. The CRD and manifests expose the new fields and related image.
Image resolution and workload wiring
api/v1beta1/openstacklightspeed_images.go, internal/controller/*deployment.go, internal/controller/*reconciler.go, internal/controller/*images_test.go
Image accessors resolve overrides or defaults. Workload builders use component-specific images and resources. Console image overrides apply to both console containers.
Controller configuration behavior
internal/controller/common.go, internal/controller/lcore_*.go, internal/controller/mcp_server.go, internal/controller/postgres_*.go, internal/controller/okp_reconciler.go
Controllers read component log levels, resources, exporter settings, and RHOS MCP configuration from the new API fields.
Configuration examples and migration coverage
config/samples/*, docs/*.rst, test/kuttl/common/*, test/kuttl/tests/{application-credentials,dynamic-crd-watch-recovery,persistent-database,rhoso-mcps-configuration,update-openstacklightspeed}/*
Samples, documentation, and existing KUTTL scenarios use component-scoped configuration and structured RHOS MCP settings.
End-to-end image override tests
test/kuttl/tests/container-image-overrides/*
KUTTL tests create image overrides and verify workload images, console updates, readiness conditions, and cleanup behavior.

Merge Risk: 🟡 Moderate · up to 9aab2

RHOS MCP image customization does not work, and misleading documentation or weak end-to-end coverage can hide unintended configuration behavior. The functional override gap should be resolved before merge.

Explanation

Docstring coverage is 45.45% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 44 functions across 17 files. (28 skipped: 28 unsupported.)

Full details: Keep Documentation Current

Explanation

The pull request adds user-facing containerImage overrides for rag, ogx, lightspeed, dataverseExporter, database, okp, and console in the CRD. The controller uses these fields to select deployed images. However, README.md and all docs/*.rst files contain no containerImage or imageContainer documentation. docs/configuration.rst states that it documents every spec field, but it omits all seven new image fields. The pull request updates logging, resources, feedback, and RHOS MCP configuration documentation, but not this new image configuration.

Resolution

Add a section to docs/configuration.rst for container image overrides. List all seven supported paths, explain that an unset field uses the operator or OCP-version default, and include a YAML example. Document the console image fallback behavior and the RAG init-container scope. Update docs/install_guide.rst if image registry or pull-credential requirements change for custom images.

Use distinct, pullable image references for all override fields.

rag, OGX, Lightspeed, exporter, PostgreSQL, and OKP use the defaults injected by config/manager/manager.yaml. The KUTTL assertions repeat those values, so a regression that drops these CR fields before reconciliation can pass. Unit tests cover distinct inputs in the builders, but not the CR-to-Deployment path.

Akrog and others added 2 commits September 11, 2026 22:41
The MCP container is missing an MCP startup probe like other containers,
so we add it in this patch.
Add functionality to allow changing the image for the different
containers.

Image is set in the `imageContainer` field that lives in each of the
different sections with a new section named `rag` being added and
allowing to set a different image for ogx/llama-stack and the lightspeed
service itself.

New environmental variable for OGX is also added named
RELATED_IMAGE_OGX_IMAGE_URL_DEFAULT.

This changes the behavior of the OGX image which previously would
*always* be the same as for lightspeed.

Now they have the same initial default, but they are not tied together,
so changing the lightspeed image (via env vars or CR) will not make OGX
use the same image.
