refactor: use in-cluster authentication instead of kubeconfig secret

RATIONALE: Gitea CI runner is running IN-CLUSTER, so we should use Kubernetes' built-in in-cluster authentication mechanism instead of storing kubeconfig secrets. IN-CLUSTER AUTHENTICATION: - Kubernetes automatically mounts service account token - Location: /var/run/secrets/kubernetes.io/serviceaccount/token - Location: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt - kubectl automatically detects and uses these - No need to pass credentials via secrets CHANGES: 1. Remove KUBECONFIG_B64 secret requirement 2. Add in-cluster auth detection step 3. Update Job to use actual built image (not golang base) 4. Job uses imagePullSecrets for registry auth (can be encrypted with SOPS) 5. Add regcred image pull secret reference CI FLOW: 1. Detect in-cluster authentication is available 2. kubectl commands automatically use mounted service account 3. No secrets needed in CI env vars 4. Job applies with RBAC service account 5. Registry credentials via imagePullSecrets (encrypted with SOPS) SECURITY: ✓ In-cluster auth is more secure (bound to service account) ✓ No kubeconfig stored in secrets ✓ Sensitive data encrypted with SOPS ✓ Principle of least privilege (service account RBAC)
refactor: use Kubernetes Job for integration testing instead of manual pod management

Admin Bot	1dd71de97f	refactor: use in-cluster authentication instead of kubeconfig secret CI / CI (pull_request) Failing after 2m56s Details RATIONALE: Gitea CI runner is running IN-CLUSTER, so we should use Kubernetes' built-in in-cluster authentication mechanism instead of storing kubeconfig secrets. IN-CLUSTER AUTHENTICATION: - Kubernetes automatically mounts service account token - Location: /var/run/secrets/kubernetes.io/serviceaccount/token - Location: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt - kubectl automatically detects and uses these - No need to pass credentials via secrets CHANGES: 1. Remove KUBECONFIG_B64 secret requirement 2. Add in-cluster auth detection step 3. Update Job to use actual built image (not golang base) 4. Job uses imagePullSecrets for registry auth (can be encrypted with SOPS) 5. Add regcred image pull secret reference CI FLOW: 1. Detect in-cluster authentication is available 2. kubectl commands automatically use mounted service account 3. No secrets needed in CI env vars 4. Job applies with RBAC service account 5. Registry credentials via imagePullSecrets (encrypted with SOPS) SECURITY: ✓ In-cluster auth is more secure (bound to service account) ✓ No kubeconfig stored in secrets ✓ Sensitive data encrypted with SOPS ✓ Principle of least privilege (service account RBAC)	2026-09-13 13:51:46 +09:00
Admin Bot	fa9938df8e	refactor: use Kubernetes Job for integration testing instead of manual pod management CI / CI (pull_request) Failing after 2m56s Details RATIONALE: The Kubernetes way to run integration tests is via Jobs, not manual pod management. Jobs are simpler, more idiomatic, and handle all the complexity for us. CHANGES: - Remove manual: kubectl run, kubectl wait, kubectl exec - Use Kubernetes Job (already defined in k8s/integration-test-job.yaml) - Job handles: pod creation, retry, cleanup, status reporting - CI only does: apply job, set image, wait, check status SIMPLIFIED CI FLOW: 1. go vet + go test (unit tests) 2. Build image: api-gateway:<sha> 3. Push: <sha> tag only 4. Apply Job from k8s/integration-test-job.yaml 5. Set job image to new build 6. Wait for job completion 7. Get logs 8. Check job status 9. Promote to latest (if job succeeded) 10. Cleanup job BENEFITS: ✅ More idiomatic (Kubernetes Job is the standard way) ✅ Simpler CI workflow (fewer manual steps) ✅ Job handles retries, backoff, cleanup automatically ✅ Better status reporting ✅ Declarative (job spec in git, not imperative in CI) ✅ Easier to test locally (just kubectl apply -f k8s/integration-test-job.yaml) WHAT KUBERNETES JOB HANDLES: ✓ Pod creation and lifecycle ✓ Restart policy and retries ✓ Cleanup on completion ✓ Status tracking ✓ Log aggregation ✓ Resource limits	2026-09-13 13:47:02 +09:00
Admin Bot	a700ac065b	fix: remove kubectl installation, assume available in runner CI / CI (pull_request) Failing after 3m6s Details OPTIMIZATIONS: - Remove curl-based kubectl installation (inefficient) - Assume kubectl is available in Gitea runner environment - Replace port-forward with kubectl exec for test execution - Tests now run directly inside test pod (not from runner) - Simpler, faster, more reliable CI Flow: 1. go vet + go test (unit tests) 2. Build image: api-gateway:<sha> 3. Push: <sha> tag only 4. Deploy test pod with proper labels 5. kubectl exec into pod to run tests 6. Tests run inside pod, can reach services via network policy 7. Promote to latest only if tests pass 8. Cleanup test pod	2026-09-13 13:44:15 +09:00
Admin Bot	e0622449cc	fix: ensure test pod can reach all downstream services CI / CI (pull_request) Failing after 2m58s Details Add labels to test pod to match network policy selectors: - app=api-gateway (matches network policy pod selector) - managed-by=argocd (matches network policy pod selector) - role=test (identify as test pod) - test-run=<sha> (track which test run spawned it) Network policy 'api-gateway' in api namespace already allows egress to: ✅ kube-system (DNS resolution) ✅ poimen (port 8080 - Memory service) ✅ temporal (port 7233 - Workflow service) ✅ storage (ports 80, 9000 - S3/MinIO) ✅ sqs (port 9090 - SQS service) ✅ iam (ports 9000, 9443 - Authentik/IAM) Test pod inherits same network access as production pods via labels.

Admin Bot	52c36e587b	feat: proper CI/CD workflow with integration testing BREAKING CHANGE: CI now requires kubeconfig to run integration tests Changes: - Build image with commit SHA tag (NOT latest yet) - Deploy dedicated test pod from new image - Run full integration test suite against test pod - Only promote to latest tag AFTER tests pass - Cleanup test pod after run CI/CD Flow: 1. go vet + go test (unit tests) 2. Build image: api-gateway:<sha> 3. Push to registry 4. Deploy test pod with <sha> image 5. Run integration tests (memory, S3, SQS, workflow, IAM, health) 6. If tests pass: tag as latest and push 7. If tests fail: keep <sha> tag, don't promote to latest 8. Cleanup test pod This ensures: - New code is tested in cluster before production deployment - ArgoCD only pulls latest after tests pass - Failed builds don't get promoted to production - Full test coverage of all adapters Requires: KUBECONFIG_B64 secret in Gitea for cluster access	2026-09-13 11:46:46 +09:00
Admin Bot	0943df8a42	feat: add comprehensive integration tests and CI pipeline CI / CI (push) Failing after 5m44s Details Add integration test suite that tests against production cluster: - Memory service (ingest, query) - S3 adapter (list, put objects) - SQS adapter (list queues with auth enforcement) - Workflow adapter (gRPC ListWorkflowExecutions) - IAM adapter (list users) - Health endpoints (liveness, readiness) Update CI/CD pipeline: - Build new docker image from commit - Push to registry with commit SHA and latest tags - Deploy test job to cluster to run integration tests - Tests run against actual production services - Cleanup test resources after completion Add Kubernetes Job manifest: - Runs integration tests in dedicated pod - Waits for gateway to be ready before testing - Tests all adapters and downstream services - Can be run manually: kubectl apply -f k8s/integration-test-job.yaml	2026-09-13 11:42:55 +09:00

Existing encrypted files will be re-encrypted with the new key during next sync. SECURITY: Private keys must NEVER be exposed in terminal output or git history.	2026-09-13 11:00:14 +09:00
Admin Bot	b8f95506ca	feat: add Temporal config and update routing with memory service integration - Add TemporalConfig struct to internal/config - Update gateway config with Temporal frontend service (port 7233) - Update router with memory service adapter support - Add config.local.yaml with memory service configuration - Encrypt production config with SOPS (AES256_GCM) - Support X-Service header routing pattern for service discovery - Keep legacy path-based routes with deprecation warnings - All 5 adapters preserved: workflow, memory, sqs, s3, iam	2026-09-13 10:56:18 +09:00
Admin Bot	67f24ea763	docs: improve .sops.yaml with public key and encryption guidance - Document public AGE key for developers - Add encrypted_regex to only encrypt data fields - Keep Kubernetes structure readable (apiVersion, kind, metadata) - Add usage examples in comments	2026-09-13 09:20:05 +09:00

Changes made: - auth.jwksUrl: port 80 → 9000 - auth.tokenUrl: port 80 → 9000 - iam.upstream: port 80 → 9000 This fixes JWKS refresh and JWT token validation. --------- Co-authored-by: rock <[email protected]> Reviewed-on: #22 Co-authored-by: poimen <[email protected]>	2026-09-13 00:07:58 +00:00
