## Context
BeadBoard is the Next.js task visualization dashboard shipped in this
stack. We want users to trigger headless Claude agent runs directly from
a beads task row — "one-click dispatch" — instead of copy-pasting `bd`
IDs into a terminal. The agent runs in-cluster as claude-agent-service
(see stacks/claude-agent-service/), protected by a bearer token in
Vault at secret/claude-agent-service/api_bearer_token.
For BeadBoard to POST to /execute we need the service URL and the
bearer token available inside the pod as env vars. The URL is static
(cluster DNS); the token must come through External Secrets Operator
so rotation in Vault propagates without re-applying Terraform.
Secondary cleanup: the container was still pinned to :latest which
violates the 8-char-SHA convention and causes stale pulls through the
registry cache (see .claude/CLAUDE.md, Docker images). The image tag
is now variable-driven; the GHA pipeline will override the default
once it publishes the first SHA.
## This change
- Adds an ExternalSecret `beadboard-agent-service` in the
`beads-server` namespace, mirroring the pattern in
stacks/claude-agent-service/main.tf (same Vault path
`secret/claude-agent-service`, same `vault-kv` ClusterSecretStore,
same 15m refresh). Exposes exactly one key: `api_bearer_token`.
- Adds two env vars to the `beadboard` container:
- `CLAUDE_AGENT_SERVICE_URL` — static cluster URL
(`http://claude-agent-service.claude-agent.svc.cluster.local:8080`)
- `CLAUDE_AGENT_BEARER_TOKEN` — `secret_key_ref` pointing at the
ESO-managed Secret, key `api_bearer_token`
- Adds `reloader.stakater.com/auto = "true"` on the Deployment's
top-level metadata — matches the convention used by rybbit,
claude-memory, onlyoffice. When ESO refreshes the K8s Secret
because Vault rotated the token, Reloader restarts the pod so the
new token is picked up (env vars are read once at boot).
- Adds `variable "beadboard_image_tag"` (default `"latest"`, with a
one-line comment flagging the temporary default). The image
reference now interpolates `${var.beadboard_image_tag}`. No tfvars
file is touched — orchestrator will flip the default to the first
real 8-char SHA once GHA publishes it.
## What is NOT in this change
- No GHA workflow additions. The pipeline that builds
`registry.viktorbarzin.me:5050/beadboard` lives in the BeadBoard
repo and is out of scope here.
- No Vault-side changes. `secret/claude-agent-service/api_bearer_token`
already exists (it powers the claude-agent-service deployment
itself).
- No Terraform `apply`. Orchestrator applies.
## Data flow
Vault (secret/claude-agent-service)
│ refresh every 15m
▼
ESO → K8s Secret `beadboard-agent-service` (beads-server ns)
│ envFrom.secretKeyRef
▼
BeadBoard pod (CLAUDE_AGENT_BEARER_TOKEN env)
│ Authorization: Bearer <token>
▼
claude-agent-service.claude-agent.svc:8080 /execute
On Vault rotation: ESO picks up new value at next refresh → K8s
Secret data changes → Reloader sees annotation + referenced Secret
changed → rolling-recreates the beadboard pod with the new token.
## Test Plan
### Automated
- `terraform fmt -recursive stacks/beads-server/` — clean (formatted
the file once; subsequent run is a no-op).
- `terraform -chdir=stacks/beads-server validate` (after
`terraform init -backend=false`) — `Success! The configuration is
valid`. The 14 "Deprecated Resource" warnings are pre-existing
(`kubernetes_namespace` vs `_v1` etc.) and unrelated to this
change.
### Manual Verification
1. Orchestrator applies:
`scripts/tg -chdir=stacks/beads-server apply`
2. Verify the ExternalSecret synced:
`kubectl -n beads-server get externalsecret beadboard-agent-service`
Expected: `Ready=True`, `SyncedAt` recent.
3. Verify the K8s Secret exists with one key:
`kubectl -n beads-server get secret beadboard-agent-service -o jsonpath='{.data.api_bearer_token}' | base64 -d | head -c 8`
Expected: first 8 chars of the bearer token.
4. Verify the deployment picked up the env vars:
`kubectl -n beads-server get deploy beadboard -o yaml | grep -A2 CLAUDE_AGENT`
Expected: both env entries present, bearer via `secretKeyRef`.
5. Verify the reloader annotation is on the Deployment metadata:
`kubectl -n beads-server get deploy beadboard -o jsonpath='{.metadata.annotations.reloader\.stakater\.com/auto}'`
Expected: `true`.
6. Verify the image tag resolved to the variable default (for now):
`kubectl -n beads-server get deploy beadboard -o jsonpath='{.spec.template.spec.containers[0].image}'`
Expected: `registry.viktorbarzin.me:5050/beadboard:latest`
(will become `...:<sha>` once `beadboard_image_tag` default is
updated).
7. Smoke-test the env var inside the pod:
`kubectl -n beads-server exec deploy/beadboard -- sh -c 'printenv CLAUDE_AGENT_SERVICE_URL; printenv CLAUDE_AGENT_BEARER_TOKEN | head -c 8'`
Expected: URL printed, first 8 chars of token printed.
