npx skillscat add terrylica/cc-skills/infra-deploy Install via the SkillsCat registry.
This skill automates the deployment of Cal.com self‑hosted to Google Cloud Run using Supabase PostgreSQL, while also supporting local development with Docker Compose. It verifies GCP project and authentication settings, Supabase configuration, required secrets, and API enablement before building and pushing the container.
Infrastructure Deployment
Deploy Cal.com self-hosted to GCP Cloud Run with Supabase PostgreSQL, or run locally via Docker Compose.
Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
Mandatory Preflight
Step 1: Check GCP Project Configuration
echo "CALCOM_GCP_PROJECT: ${CALCOM_GCP_PROJECT:-NOT_SET}"
echo "CALCOM_GCP_ACCOUNT: ${CALCOM_GCP_ACCOUNT:-NOT_SET}"
echo "CALCOM_GCP_REGION: ${CALCOM_GCP_REGION:-us-central1}"If NOT_SET: These must be configured in .mise.local.toml. Run the setup command.
Step 2: Verify GCP Authentication
gcloud auth list --filter="status=ACTIVE" --format="value(account)" 2>/dev/nullStep 3: Check Supabase Configuration
echo "SUPABASE_PROJECT_REF: ${SUPABASE_PROJECT_REF:-NOT_SET}"
echo "SUPABASE_DB_URL_REF: ${SUPABASE_DB_URL_REF:-NOT_SET}"Step 4: Verify Cal.com Secrets
echo "CALCOM_NEXTAUTH_SECRET_REF: ${CALCOM_NEXTAUTH_SECRET_REF:-NOT_SET}"
echo "CALCOM_ENCRYPTION_KEY_REF: ${CALCOM_ENCRYPTION_KEY_REF:-NOT_SET}"
echo "CALCOM_CRON_API_KEY_REF: ${CALCOM_CRON_API_KEY_REF:-NOT_SET}"All 1Password references must be SET. Secrets are stored in Claude Automation vault.
Deploy Target: GCP Cloud Run
Step 1: Verify GCP APIs Enabled
gcloud services list --enabled \
--project="$CALCOM_GCP_PROJECT" \
--account="$CALCOM_GCP_ACCOUNT" 2>/dev/null | grep -E "run|artifact|build"Required APIs: Cloud Run, Artifact Registry, Cloud Build.
Step 2: Build Container
# From the cal.com fork directory
cd ~/fork-tools/cal.com
# Build Docker image
docker build -t calcom-self-hosted .Step 3: Push to Artifact Registry
# Tag for Artifact Registry
docker tag calcom-self-hosted \
"${CALCOM_GCP_REGION}-docker.pkg.dev/${CALCOM_GCP_PROJECT}/calcom/calcom:latest"
# Push
docker push \
"${CALCOM_GCP_REGION}-docker.pkg.dev/${CALCOM_GCP_PROJECT}/calcom/calcom:latest"Step 4: Deploy to Cloud Run

Lightweight Cloud Run service bridging Cal.com webhooks to Pushover emergency alerts. Zero dependencies (Python stdlib only).
Step 1: Verify Pushover Credentials
echo "PUSHOVER_APP_TOKEN: ${PUSHOVER_APP_TOKEN:+SET}"
echo "PUSHOVER_USER_KEY: ${PUSHOVER_USER_KEY:+SET}"
echo "PUSHOVER_SOUND: ${PUSHOVER_SOUND:-dune}"All must be SET. See pushover-setup.md for credential setup.
Step 2: Deploy Webhook Relay to Cloud Run
RELAY_SOURCE="$HOME/.claude/plugins/marketplaces/cc-skills/plugins/calcom-commander/scripts/webhook-relay"
gcloud run deploy calcom-pushover-webhook \
--source "$RELAY_SOURCE" \
--project="$CALCOM_GCP_PROJECT" \

--min-instances=0 \
--max-instances=1 \
--timeout=30 \
--quietNote the Service URL from the output. Store in .mise.local.toml as WEBHOOK_RELAY_URL.
Step 3: Verify Health
curl -s "$WEBHOOK_RELAY_URL" | python3 -m json.tool
# Expected: {"status": "healthy", "service": "calcom-pushover-webhook"}Step 4: Register Cal.com Webhook
CALCOM_API_KEY=$(op item get "$CALCOM_OP_UUID" --vault "Claude Automation" --fields password --reveal)
curl -s -X POST "https://api.cal.com/v1/webhooks?apiKey=$CALCOM_API_KEY" \
-H "Content-Type: application/json" \
-d "{\"subscriberUrl\":\"$WEBHOOK_RELAY_URL\",\"eventTriggers\":[\"BOOKING_CREATED\",\"BOOKING_RESCHEDULED\",\"BOOKING_CANCELLED\"],\"active\":true}"Step 5: Test with Simulated Booking
curl -s -X POST "$WEBHOOK_RELAY_URL" \
-H "Content-Type: application/json" \
-d '{"triggerEvent":"BOOKING_CREATED","payload":{"title":"Test Meeting","attendees":[{"name":"Test User"}],"startTime":"2026-01-01T10:00:00Z","endTime":"2026-01-01T10:30:00Z"}}'Expected: Pushover emergency alert with "dune" sound on your device.
Supabase Database Management
Check Connection
DATABASE_URL=$(op read "$SUPABASE_DB_URL_REF")
psql "$DATABASE_URL" -c "SELECT version();"Run Migrations
cd ~/fork-tools/cal.com
DATABASE_URL=$(op read "$SUPABASE_DB_URL_REF") npx prisma migrate deploy1Password Secret References
All secrets in Claude Automation vault (biometric-free access):
| Secret | 1Password Reference |

- YAML frontmatter valid (no colons in description)
- Trigger keywords current
- Path patterns use $HOME not hardcoded paths
- 1Password references are agnostic (no hardcoded UUIDs)
Post-Execution Reflection
After this skill completes, reflect before closing the task:
- Locate yourself. — Find this SKILL.md's canonical path before editing.
- What failed? — Fix the instruction that caused it.
- What worked better than expected? — Promote to recommended practice.
- What drifted? — Fix any script, reference, or dependency that no longer matches reality.
- Log it. — Evolution-log entry with trigger, fix, and evidence.
Do NOT defer. The next invocation inherits whatever you leave behind.
