inter-hub on Railiance01 — Runbook

Architecture

• Cluster: Railiance01 (K3s, 92.205.62.239)
• Namespace: inter-hub
• Image registry: 92.205.130.254:32166/coulomb/inter-hub:<sha> (Gitea on CoulombCore)
• Database: CloudNativePG cluster net-kingdom-pg in databases namespace
  • RW endpoint: net-kingdom-pg-rw.databases.svc.cluster.local:5432
  • Database: interhub, User: interhub
• Ingress: Traefik → hub.coulomb.social (TLS via letsencrypt-prod)
• Secrets: inter-hub-env Secret in inter-hub namespace

Deployment

# From workstation (image already built and pushed):
helm upgrade --install inter-hub deploy/helm/inter-hub \
  --namespace inter-hub --create-namespace \
  --set image.tag=<sha>

Image Build (on haskelseed)

ssh root@192.168.178.135
cd /root/inter-hub
git pull  # (requires Gitea auth — see Gitea credentials section)
nix build .#docker --accept-flake-config --option lazy-trees false
# Push to Gitea registry:
skopeo copy docker-archive:result \
  docker://92.205.130.254:32166/coulomb/inter-hub:<sha> \
  --dest-creds "tegwick:<GITEA_TOKEN>" \
  --dest-tls-verify=false

Gitea Registry Credentials

The Gitea token for registry push is stored in ~/.config/tea/config.yml on the workstation. If the token has expired, generate a new one:

1. Go to http://92.205.130.254:32166 → Settings → Applications → Generate new token
2. Scope: package:write
3. Update ~/.config/tea/config.yml on the workstation
4. Update the GITEA_TOKEN in any CI/CD secrets

Database Migration

IHP migrations run automatically on startup via the init container in the Deployment. To run migrations manually:

kubectl exec -n inter-hub deploy/inter-hub -- /bin/App migrate

To check migration status:

kubectl exec -n databases net-kingdom-pg-1 -- psql -U postgres interhub -c "\dt"

Logs

kubectl logs -n inter-hub -l app=inter-hub --tail=100 -f
# Previous pod logs:
kubectl logs -n inter-hub -l app=inter-hub --previous --tail=50

Restart / Rollback

# Restart:
kubectl rollout restart deployment/inter-hub -n inter-hub
kubectl rollout status deployment/inter-hub -n inter-hub

# Rollback to previous image:
kubectl rollout undo deployment/inter-hub -n inter-hub

# Rollback to specific version:
helm rollback inter-hub 1 --namespace inter-hub

Secret Rotation

To rotate the session secret:

kubectl create secret generic inter-hub-env \
  --namespace inter-hub \
  --from-literal=DATABASE_URL='...' \
  --from-literal=IHP_SESSION_SECRET='<new-64-char-hex>' \
  --from-literal=IHP_BASEURL='https://hub.coulomb.social' \
  --from-literal=PORT='8000' \
  --from-literal=IHP_ENV='Production' \
  --dry-run=client -o yaml | kubectl apply -f -
kubectl rollout restart deployment/inter-hub -n inter-hub

To rotate the database password:

1. Update the password in PostgreSQL (via kubectl exec to the CNPG pod)
2. Update the inter-hub-env secret
3. Restart the deployment

Smoke Test

curl -s https://hub.coulomb.social/ | grep "Inter-Hub"           # Landing 200
curl -s https://hub.coulomb.social/capabilities | grep "Capabilities"
curl -s https://hub.coulomb.social/api/v2/hubs                   # 401 expected
curl -H "Authorization: Bearer <api-key>" https://hub.coulomb.social/api/v2/hubs  # 200

Database Connection Check

kubectl exec -n inter-hub deploy/inter-hub -- \
  /bin/sh -c 'psql $DATABASE_URL -c "SELECT version();"'
