- Only Keycloak and the Portal get NodePorts by default. To reach OEG, SRM or Federation Manager from

  outside, set their `service.type` and `service.nodePort` (as `environments/kind/values.yaml` does).

- SRM has no control paths or topology by default, so it can't deploy anything until you set

  `srm.controlPaths`, `topology` and `workloads.namespaces`; see the

  the complete `srm.topology` bootstrap and `workloads.namespaces`; see the

  [SRM README](oop-platform-chart/charts/srm/README.md).

- Federation partners must reach FM's callback links: set

  `federation-manager.publicUrl`; see the

    nodePort: 32415

  workloads:

    namespaces: [oop-apps]

  controlPaths:

    - control_path_ref: k8s-local

It is meant to be installed through the umbrella chart `oop-platform`.

## Status

## Release compatibility

This chart targets SRM branch `refactor/tf-sdk-wiring`. Two things are still pending in the SRM

repository before it works end to end:

- **The image doesn't build as-is**: that branch pulls tf-sdk from a local path (`../tf-sdk`),

  which the official Dockerfile can't resolve.

- **The image has no `helm` binary**, which the `kubernetes` adapter runs to install workloads.

The chart is written for the image you get once both are fixed.

Use the SRM single-bootstrap change with SDK 2.0.0rc3 and its matching image.

The current release integration base is `refactor/tf-sdk-srm-bug-fixes`; its

Dockerfile already installs Helm 3.18.6 and uses the SDK package index. The new

candidate package/image must be available before deployment. Upgrade or roll

back SDK, SRM, chart and configuration together.

## What SRM needs

| `federationManager.url` | string | `""` | Federation Manager internal API address; empty = `http://<global.federationManager.host>:<port>` (`http://federation-manager-internal:8083`) |

| `federationManager.timeout` | number | `5` | Seconds per Federation Manager call |

| `zoneProviderName` | string | `""` | Provider name SRM reports for its zones; empty = SRM's default (`oop-provider`) |

| `controlPaths` | list | `[]` | tf-sdk adapters SRM can use (see [Control paths](#control-paths)) |

| `controlPaths` | list | `[]` | Retired; nonempty input fails with a migration error |

| `controlPathCredentials` | list | `[]` | Generated references to existing credential Secret mounts |

| `topology` | string | `""` | Bootstrap topology YAML (see [Bootstrap topology](#bootstrap-topology)) |

| `workloads.namespaces` | list | `[]` | Namespaces SRM may deploy workloads into (kind: `[oop-apps]`) |

| `workloads.createNamespaces` | bool | `true` | Create those namespaces |

| `serviceAccount.create` | bool | `true` | Create SRM's ServiceAccount |

| `serviceAccount.name` | string | `""` | ServiceAccount name; empty = `name` |

## Control paths

A control path is one configured tf-sdk adapter, known by a name you choose

(`control_path_ref`). SRM builds its adapters from this list at startup; topology bindings (below)

point at them by that name. The chart passes the list to SRM as JSON in

`CONTROL_PATH_SETTINGS__ENTRIES`.

## One bootstrap for control paths and topology

Each entry has three fields:

| Field | Meaning |

|---|---|

| `control_path_ref` | Name of this control path |

| `adapter` | tf-sdk adapter type: `kubernetes`, `oai`, `open5gs`, `open5gcore`, `i2cat_ric` or `i2edge` |

| `config` | Adapter settings, different per adapter |

Put the complete SDK bootstrap in `topology`. SRM loads one

revision and derives discovery and its execution registry from it. Remove the

old independent `controlPaths` list. Instance identity is derived from each

`control_paths[].ref`; do not repeat it in infrastructure configuration.

A Kubernetes cluster (the one SRM runs in) and a 5G core:

For the cluster SRM runs in:

```yaml

srm:

  topology: |

    version: openop.srm.bootstrap/v1

    control_paths:

      - ref: local-workloads

        adapter_type: kubernetes

        infrastructure:

          in_cluster: true

          namespace: applications

    zones: []  # Add the declared zones/domains/capabilities/bindings for execution.

  workloads:

    namespaces: [oop-apps]

  controlPaths:

    - control_path_ref: k8s-local

      adapter: kubernetes

      config:

        namespace: oop-apps

    - control_path_ref: open5gs-lab

      adapter: open5gs

      config:

        base_url: http://nef.core.example:8000

        scs_as_id: oop

    namespaces: [applications]

```

- `kubernetes`: `namespace` is where workloads go. The adapter runs the `helm` CLI with the pod's

  own ServiceAccount, so the namespace must also be listed in `workloads.namespaces` for SRM to

  have permission there.

- Network adapters (`oai`, `open5gs`, `open5gcore`, `i2cat_ric`): `base_url` and `scs_as_id`,

  plus an optional `notification_url`.

- `i2edge`: `base_url` and `flavour_id`.

## Bootstrap topology

The topology file tells SRM which zones, domains and capabilities the platform has, and which

control path serves each capability. Put the whole YAML in `topology` as a string; the chart

mounts it and sets `BOOTSTRAP_TOPOLOGY_PATH`. With `topology` empty SRM discovers no topology.

- Format: `version: openop.srm.bootstrap/v1`. A full example with every field is tf-sdk's

  [`tests/contract/bootstrap_example.yaml`](https://labs.etsi.org/rep/oop/code/tf-sdk/-/blob/refactor/tfsdk-architecture-alignment/tests/contract/bootstrap_example.yaml);

  `environments/kind/values.yaml` has a small working one (one zone, one Kubernetes domain).

- **Refs must match.** Every `control_path_bindings[].control_path_ref` in the topology must be a

  `control_path_ref` in `controlPaths`. SRM only logs a warning when one isn't, and requests routed

  through that binding then fail.

- At startup SRM **only adds** zones, domains, capabilities and bindings that aren't in its

  database yet; it never updates or deletes existing ones. Changing an existing entry in the file

  has no effect on a running installation.

- Changing `topology` restarts the pod (the Deployment carries a checksum of it).

For a remote cluster, declare `kubeconfig_path`, `kube_context` and namespace

in the bootstrap. Supply matching mount metadata:

```yaml

controlPathCredentials:

  - controlPathRef: athens

    existingSecret: athens-credentials

    key: config

    mountPath: /etc/openop/kubeconfigs/athens

```

The matching bootstrap path is `/etc/openop/kubeconfigs/athens/config`. The

Secret must already exist in SRM's namespace. Its other files are available

alongside the config for relative certificate/token paths. The directory is

mounted read-only without `subPath`, allowing projected token files to rotate.

Kubeconfig changes require a new SDK instance/Pod; the SDK pins the selected

profile on first use. The SDK does not resolve Secret URIs.

The chart rejects missing, duplicate or mismatched credential mounts and

retired registry values before deployment. The existing Ansible `oop-platform`

role can generate bootstrap and mount metadata from one operator declaration,

avoiding manual duplication of file paths. Chart rendering validates mapping;

it does not establish that remote credentials or backends work.

A disk-backed `emptyDir` at `/var/run/openop-tfsdk` holds private SDK execution

files. This chart supports that runtime directory. Credential-provider plugins,

ambient connection defaults and independent `api_server` overrides are

unsupported by the paired SDK candidate. `endpoint_host`, if needed, addresses

the deployed application rather than the Kubernetes API server.

Bootstrap is declared topology, not backend health. SRM keeps create-missing

seeding: existing DB entries are not updated or deleted by this change.

Changing `topology` restarts the Pod through its existing checksum annotation.

Offline chart verification:

```sh

HELM_BINARY=/path/to/helm python -m pytest tests/test_srm_bootstrap.py

```

## Workload namespaces and RBAC

- Pod stuck in `Init`: the `srm` database or role isn't there yet, or the password in

  `postgres-credentials` → `srm-password` doesn't match.

- `bootstrap_binding_unknown_control_path` in the logs: a topology binding names a control path

  that isn't in `controlPaths`.

  that isn't declared in bootstrap `control_paths`.

- Deploys fail with "forbidden": the adapter's namespace isn't in `workloads.namespaces`.
