# 08 — Deploy Pipeline Update (Prod)

## Context
- **File:** `.gitea/workflows/deploy-prod.yml`
- Same changes as test pipeline (`test-env-setup/07-deploy-pipeline-update.md`),
  adapted for prod paths and prod runner.
- **Prod-specific differences from test:**
  - `SPRING_PROFILES_ACTIVE=prod` (not `test`) in Run APISIX Init
  - DB hostnames: `postgresql`, `mongodb` (Swarm overlay DNS — same as test)
  - Storagebox paths via env vars (`SWAG_CERT_DIR`, `SWAG_CONFIG_DIR`, vb.) instead of local host paths
  - Extra steps: Update DNS Records (GoDaddy API), Wait for etcd

## Step 1 — Remove manual cert scp lines from `Initialize Workspace`

```yaml
# DELETE from "Initialize Servers" step:
          scp -P 23 ${{ vars.STORAGEBOX_USER }}@${{ vars.STORAGEBOX_USER }}.your-storagebox.de:prod/app/iklim.co/ssl/STAR.iklim.co.full.crt ./STAR.iklim.co.full.crt
          scp -P 23 ${{ vars.STORAGEBOX_USER }}@${{ vars.STORAGEBOX_USER }}.your-storagebox.de:prod/app/iklim.co/ssl/STAR.iklim.co_key.pem ./STAR.iklim.co_key.pem
```

Also remove from `Prepare Init Files`:
```yaml
# DELETE or make conditional:
          sudo cp STAR.iklim.co.full.crt STAR.iklim.co_key.pem /opt/iklimco/ssl/
```

## Step 2 — Add `Update DNS Records` step

Insert **after** `Docker Login to Harbor` and **before** `Prepare SWAG Directories`.

```yaml
      - name: Update DNS Records
        run: |
          set -a; . ./.env; . ./.env.secrets.swag; set +a
          FLOATING_IP="${{ vars.PROD_FLOATING_IP }}"
          DOMAIN="iklim.co"

          for record in api apigw rabbitmq grafana; do
            CURRENT=$(curl -s \
              -H "Authorization: sso-key ${GODADDY_KEY}:${GODADDY_SECRET}" \
              "https://api.godaddy.com/v1/domains/${DOMAIN}/records/A/${record}" \
              2>/dev/null | jq -r '.[0].data // empty' 2>/dev/null || true)

            if [ "$CURRENT" = "$FLOATING_IP" ]; then
              echo "✅ ${record}.${DOMAIN} → ${FLOATING_IP} (exists, skipping)"
            else
              curl -sf -X PUT \
                -H "Authorization: sso-key ${GODADDY_KEY}:${GODADDY_SECRET}" \
                -H "Content-Type: application/json" \
                "https://api.godaddy.com/v1/domains/${DOMAIN}/records/A/${record}" \
                -d "[{\"data\":\"${FLOATING_IP}\",\"ttl\":600}]"
              echo "✅ ${record}.${DOMAIN} → ${FLOATING_IP} (added/updated)"
            fi
          done
        working-directory: /workspace/iklim.co
```

> `GODADDY_KEY` and `GODADDY_SECRET` are read from `.env.secrets.swag`.
> `PROD_FLOATING_IP` must be defined as a Gitea project variable (`terraform output prod_floating_ip`).
> `jq` is required — it must have been added to the `Update Apt Repository` step: `apt-get install -y gettext tree jq`.
> Runs on every deploy; existing and correct records are skipped (idempotent).

## Step 3 — Add `Prepare SWAG Directories` step

Insert **before** `Bootstrap Vault TLS Placeholder`:

```yaml
      - name: Prepare SWAG Directories
        run: |
          set -a; . ./.env; . ./.env.secrets.swag; set +a

          mkdir -p "$SWAG_CONFIG_DIR/dns-conf" "$SWAG_SITE_CONFS_DIR"

          envsubst < template/swag/dns-conf/godaddy.ini.tpl | docker run --rm -i \
            -v "${SWAG_CONFIG_DIR}/dns-conf:/output" \
            alpine sh -c "cat > /output/godaddy.ini && chmod 600 /output/godaddy.ini"
          echo "✅ godaddy.ini written"

          export RESTRICTED_IPS_BLOCK="$(echo "$RESTRICTED_IPS" | tr ',' '\n' | sed 's|.*|        allow &;|')"

          SWAG_VARS='${API_SUBDOMAIN}${APIGW_SUBDOMAIN}${GRAFANA_SUBDOMAIN}${RABBITMQ_SUBDOMAIN}${RESTRICTED_IPS_BLOCK}'
          for tpl in template/swag/site-confs/*.conf.tpl; do
            fname=$(basename "${tpl%.tpl}")
            envsubst "$SWAG_VARS" < "$tpl" | docker run --rm -i \
              -v "${SWAG_SITE_CONFS_DIR}:/output" \
              alpine sh -c "cat > /output/${fname}"
            echo "✅ ${fname}"
          done

          cat template/swag/site-confs/default.conf | docker run --rm -i \
            -v "${SWAG_SITE_CONFS_DIR}:/output" \
            alpine sh -c "cat > /output/default.conf"

          echo "✅ SWAG directories ready"

          SWAG_CTR=$(docker ps -q -f name=iklimco_swag 2>/dev/null | head -1)
          if [ -n "$SWAG_CTR" ]; then
            docker exec "$SWAG_CTR" nginx -t && docker exec "$SWAG_CTR" nginx -s reload
            echo "✅ SWAG nginx reloaded"
          fi
        working-directory: /workspace/iklim.co
```

> `.env` is sourced first so `API_SUBDOMAIN=api.iklim.co` (prod values) are used.
> Ensure these vars are in `prod/secrets/iklim.co/.env.prod` on storagebox.

## Step 4 — Add `Wait for etcd` step

Insert **after** `Deploy Swarm Stack` and **before** `Run APISIX Init`.
APISIX reads its entire configuration from etcd; init script will fail silently if etcd is not ready.

```yaml
      - name: Wait for etcd
        run: |
          echo "⏳ Waiting for Patroni etcd..."
          for i in $(seq 1 30); do
            if docker run --rm --network iklimco-net alpine \
                sh -c "wget -qO- http://etcd-01:2379/health 2>/dev/null | grep -q '\"health\":\"true\"'"; then
              echo "✅ Patroni etcd ready"
              break
            fi
            [ "$i" -eq 30 ] && echo "❌ Patroni etcd did not become ready in time" && exit 1
            echo "  attempt $i/30 — waiting 5s..."
            sleep 5
          done
```

> **Note:** In prod, APISIX uses the 3-node Patroni etcd cluster on DB nodes (`etcd-01/02/03:2379`) via the `/apisix` prefix — resolved through `iklimco-net` overlay DNS aliases defined in `docker-stack-db.prod.yml`. The standalone `etcd` service from the base stack is disabled (`replicas: 0` in the prod overlay) and removed from the service list by a post-deploy step. This step waits for Patroni etcd (`etcd-01:2379`) to be healthy before running the APISIX init script.

## Step 5 — Add `Run APISIX Init` step

Insert **after** `Wait for etcd` and **before** `Bootstrap SWAG Certificate`.

```yaml
      - name: Run APISIX Init
        run: |
          set -a; . ./.env; . ./.env.secrets.shared; set +a
          echo "⏳ Waiting for Swarm APISIX..."
          until curl -sf -o /dev/null \
            -H "X-API-KEY: ${APISIX_ADMIN_KEY}" \
            "http://apisix:9180/apisix/admin/upstreams" 2>/dev/null; do
            sleep 5
          done
          export SPRING_PROFILES_ACTIVE=prod
          /bin/bash init/apisix-core/init.sh
          echo "✅ APISIX routes configured"
        working-directory: /workspace/iklim.co
```

> **Prod-specific:** `SPRING_PROFILES_ACTIVE=prod` — test pipeline uses `test`.
> `APISIX_ADMIN_KEY` is sourced from `.env.secrets.shared`.
> The init script is idempotent (PUT semantics); safe to re-run on subsequent deploys.
> With `replicas: 3` in prod, all APISIX instances read the same etcd state — no per-replica init needed.

## Step 6 — Add `Bootstrap SWAG Certificate` step

Insert **after** `Run APISIX Init`:

```yaml
      - name: Bootstrap SWAG Certificate
        run: |
          set -a; . ./.env; set +a
          echo "Waiting for SWAG container to start..."
          SWAG_CTR=""
          for i in $(seq 1 24); do
            SWAG_CTR=$(docker ps -q -f name=iklimco_swag 2>/dev/null | head -1)
            [ -n "$SWAG_CTR" ] && break
            sleep 10
          done

          if [ -z "$SWAG_CTR" ]; then
            echo "❌ SWAG container did not start"
            exit 1
          fi

          CERT_PATH="/config/etc/letsencrypt/live/iklim.co/fullchain.pem"
          echo "Waiting for cert (up to 10 min)..."
          for i in $(seq 1 20); do
            if docker exec "$SWAG_CTR" test -f "$CERT_PATH" 2>/dev/null; then
              echo "✅ Cert obtained"
              break
            fi
            echo "  attempt $i/20 — waiting 30s..."
            sleep 30
          done

          if ! docker exec "$SWAG_CTR" test -f "$CERT_PATH" 2>/dev/null; then
            echo "❌ SWAG did not obtain cert. Logs:"
            docker service logs iklimco_swag --tail 50
            exit 1
          fi

          docker exec "$SWAG_CTR" cat "$CERT_PATH" | \
            docker run --rm -i -v "${SWAG_CERT_DIR}:/output" alpine \
              sh -c "cat > /output/STAR.iklim.co.full.crt && chmod 644 /output/STAR.iklim.co.full.crt"
          docker exec "$SWAG_CTR" cat "/config/etc/letsencrypt/live/iklim.co/privkey.pem" | \
            docker run --rm -i -v "${SWAG_CERT_DIR}:/output" alpine \
              sh -c "cat > /output/STAR.iklim.co_key.pem && chmod 644 /output/STAR.iklim.co_key.pem"
          echo "✅ Cert bootstrapped to ${SWAG_CERT_DIR}/"
        working-directory: /workspace/iklim.co
```

## Step 7 — Add `Run Database Init Scripts` step

Insert **after** `Bootstrap SWAG Certificate` and **before** `Review Environment`.

```yaml
      - name: Run Database Init Scripts
        run: |
          set -a; . ./.env; . ./.env.secrets.shared; set +a

          echo "⏳ Waiting for PostgreSQL..."
          until docker run --rm --network iklimco-net \
            -e PGPASSWORD="${DATABASE_POSTGRES_ROOT_PASSWD}" \
            postgis/postgis:18-3.6 \
            pg_isready -h postgresql -U "${DATABASE_POSTGRES_ROOT_USER}" -q 2>/dev/null; do
            sleep 5
          done
          for sql_file in $(ls ./init/postgresql/*.sql 2>/dev/null | sort); do
            echo "▶ $(basename "$sql_file")"
            docker run --rm -i --network iklimco-net \
              -e PGPASSWORD="${DATABASE_POSTGRES_ROOT_PASSWD}" \
              postgis/postgis:18-3.6 \
              psql -h postgresql -U "${DATABASE_POSTGRES_ROOT_USER}" < "$sql_file"
          done

          echo "⏳ Waiting for MongoDB..."
          until docker run --rm --network iklimco-net mongo:8.3.2 \
            mongosh "mongodb://${DATABASE_MONGODB_ROOT_USER}:${DATABASE_MONGODB_ROOT_PASSWD}@mongodb/admin" \
            --eval "db.runCommand({ping:1})" --quiet 2>/dev/null; do
            sleep 5
          done
          for js_file in $(ls ./init/mongodb/*.js 2>/dev/null | sort); do
            echo "▶ $(basename "$js_file")"
            docker run --rm -i --network iklimco-net mongo:8.3.2 \
              mongosh "mongodb://${DATABASE_MONGODB_ROOT_USER}:${DATABASE_MONGODB_ROOT_PASSWD}@mongodb/admin" \
              --quiet < "$js_file"
          done
          echo "✅ Database init scripts completed"
        working-directory: /workspace/iklim.co
```

> **Prod-specific:** DB hostnames are `postgresql` and `mongodb` (Swarm VIP service names).
> Test pipeline uses `postgresql` / `mongodb` (unqualified aliases within the same stack).
> SQL and JS files are generated by `Prepare Init Files` step via `init_postgresql` / `init_mongodb` functions in `common-functions-prod.sh`.
> Step is idempotent — scripts use `CREATE IF NOT EXISTS` / `createCollection` semantics.

## Step 8 — Microservice prod deploy overlay

Each microservice has its own `docker-stack-service.prod.yml` overlay file. This file contains prod-specific `replicas: 3` and `max_replicas_per_node: 1` settings.

In microservice deploy pipelines (`deploy-prod.yml`), the `docker stack deploy` command should be:

```bash
docker stack deploy \
  -c BE-<ServiceName>/docker-stack-service.yml \
  -c BE-<ServiceName>/docker-stack-service.prod.yml \
  iklimco
```

For example, for `BE-Authentication`:

```bash
docker stack deploy \
  -c BE-Authentication/docker-stack-service.yml \
  -c BE-Authentication/docker-stack-service.prod.yml \
  iklimco
```

> When a new microservice is added, `BE-<ServiceName>/docker-stack-service.prod.yml` must be created and the pipeline must include this overlay.

## Step 9 — Ensure subdomain env vars are in prod `.env`

Add to `prod/secrets/iklim.co/.env.prod` on storagebox:

```bash
API_SUBDOMAIN=api.iklim.co
APIGW_SUBDOMAIN=apigw.iklim.co
RABBITMQ_SUBDOMAIN=rabbitmq.iklim.co
GRAFANA_SUBDOMAIN=grafana.iklim.co
```

## Step 10 — Final step order for prod pipeline

To prevent concurrent deploys, a Gitea Actions `concurrency` block is added per pipeline:

```yaml
concurrency:
  group: prod-deploy
  cancel-in-progress: false
```

With `cancel-in-progress: false`, a new run waits in the queue until the previous one finishes; Gitea UI shows it as "queued" and does not return an error.

1. Checkout Branch
2. Prepare Folders
3. Set up SSH Key and Add to known_hosts
4. Update Apt Repository and Install Required Tools (`gettext tree jq`)
5. Fetch Service Secret Files
6. Initialize Workspace ← cert scp lines removed
7. Upload Updated Secrets to Storagebox
8. Provision Vault AppRole IDs and Docker Secrets
9. Upload Updated Env to Storagebox
10. Prepare Init Files ← cert copy lines removed
11. Initialize Docker Swarm
12. Docker Login to Harbor
13. **Update DNS Records** ← NEW (GoDaddy API, idempotent)
14. **Prepare SWAG Directories** ← NEW (`$SWAG_CONFIG_DIR/dns-conf`; renders nginx conf templates)
15. Bootstrap Vault TLS Placeholder
16. Deploy Swarm Stack
17. **Wait for etcd** ← NEW (Patroni etcd `etcd-01:2379` overlay DNS)
18. **Run APISIX Init** ← NEW (`SPRING_PROFILES_ACTIVE=prod`)
19. **Bootstrap SWAG Certificate** ← NEW
20. **Run Database Init Scripts** ← NEW (`postgresql`, `mongodb`)
21. Review Environment
