# Cameleer SaaS Install Script — Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Create a professional installer (bash + PowerShell) for the Cameleer SaaS platform, preceded by consolidating all service init logic into Docker images to eliminate bind-mounted config files.

**Architecture:** Two-phase approach — first consolidate 7 services into 5 by baking init scripts into custom Docker images, then build dual-platform installer scripts that embed compose templates and generate all configuration from user input. The installer supports simple/expert/silent modes with idempotent re-run capability.

**Tech Stack:** Docker, Bash, PowerShell, Traefik v3, PostgreSQL 16, ClickHouse, Logto (OIDC)

**Spec:** `docs/superpowers/specs/2026-04-13-install-script-design.md`

## File Map

### Phase 1 — New files (image consolidation)

| File | Purpose |
|---|---|
| `docker/cameleer-postgres/Dockerfile` | PostgreSQL with init script baked in |
| `docker/cameleer-postgres/init-databases.sh` | Copied from `docker/init-databases.sh` |
| `docker/cameleer-clickhouse/Dockerfile` | ClickHouse with init + config baked in |
| `docker/cameleer-clickhouse/init.sql` | Copied from `docker/clickhouse-init.sql` |
| `docker/cameleer-clickhouse/users.xml` | From `docker/clickhouse-users.xml`, password via `from_env` |
| `docker/cameleer-clickhouse/prometheus.xml` | Copied from `docker/clickhouse-config.xml` |
| `docker/cameleer-traefik/Dockerfile` | Traefik with configs + cert generation baked in |
| `docker/cameleer-traefik/entrypoint.sh` | Cert generation + Traefik startup |
| `docker/cameleer-traefik/traefik.yml` | Copied from root `traefik.yml` |
| `docker/cameleer-traefik/traefik-dynamic.yml` | Copied from `docker/traefik-dynamic.yml` |

### Phase 1 — Modified files

| File | Change |
|---|---|
| `ui/sign-in/Dockerfile` | Add bootstrap deps + scripts, new entrypoint |
| `docker-compose.yml` | Remove bind mounts, init containers, use new images |
| `.env.example` | Simplify for new compose structure |
| `docker/logto-bootstrap.sh` | Make package install conditional (Alpine vs Debian) |
| `.gitea/workflows/ci.yml` | Add builds for postgres, clickhouse, traefik images; update Logto build context |

### Phase 1 — Deleted files

| File | Reason |
|---|---|
| `docker/clickhouse-init.sql` | Moved to `docker/cameleer-clickhouse/init.sql` |
| `docker/clickhouse-users.xml` | Moved (with modification) to `docker/cameleer-clickhouse/users.xml` |
| `docker/clickhouse-config.xml` | Moved to `docker/cameleer-clickhouse/prometheus.xml` |
| `docker/traefik-dynamic.yml` | Moved to `docker/cameleer-traefik/traefik-dynamic.yml` |
| `docker/vendor-seed.sh` | Logic already integrated in `logto-bootstrap.sh` Phase 12 |
| `traefik.yml` | Moved to `docker/cameleer-traefik/traefik.yml` |
| `docker/init-databases.sh` | Moved to `docker/cameleer-postgres/init-databases.sh` |

### Phase 2 & 3 — New files (installer)

| File | Purpose |
|---|---|
| `installer/install.sh` | Bash installer for Linux |
| `installer/install.ps1` | PowerShell installer for Windows |

---

## Phase 1: Platform Image Consolidation

### Task 1: Create cameleer-postgres image

**Files:**
- Create: `docker/cameleer-postgres/Dockerfile`
- Create: `docker/cameleer-postgres/init-databases.sh` (copy from `docker/init-databases.sh`)

- [ ] **Step 1: Create the Dockerfile**

```dockerfile
FROM postgres:16-alpine
COPY init-databases.sh /docker-entrypoint-initdb.d/init-databases.sh
RUN chmod +x /docker-entrypoint-initdb.d/init-databases.sh
```

- [ ] **Step 2: Copy the init script**

```bash
mkdir -p docker/cameleer-postgres
cp docker/init-databases.sh docker/cameleer-postgres/init-databases.sh
```

- [ ] **Step 3: Build and verify**

```bash
docker build -t cameleer-postgres:test docker/cameleer-postgres/
docker run --rm -e POSTGRES_USER=cameleer -e POSTGRES_PASSWORD=test -e POSTGRES_DB=cameleer_saas \
  cameleer-postgres:test postgres --version
```

Expected: PostgreSQL version output, no build errors.

- [ ] **Step 4: Commit**

```bash
git add docker/cameleer-postgres/
git commit -m "feat: create cameleer-postgres image with init script baked in"
```

---

### Task 2: Create cameleer-clickhouse image

**Files:**
- Create: `docker/cameleer-clickhouse/Dockerfile`
- Create: `docker/cameleer-clickhouse/init.sql` (copy from `docker/clickhouse-init.sql`)
- Create: `docker/cameleer-clickhouse/users.xml` (from `docker/clickhouse-users.xml`, modified)
- Create: `docker/cameleer-clickhouse/prometheus.xml` (copy from `docker/clickhouse-config.xml`)

- [ ] **Step 1: Create the Dockerfile**

```dockerfile
FROM clickhouse/clickhouse-server:latest
COPY init.sql /docker-entrypoint-initdb.d/init.sql
COPY users.xml /etc/clickhouse-server/users.d/default-user.xml
COPY prometheus.xml /etc/clickhouse-server/config.d/prometheus.xml
```

- [ ] **Step 2: Copy and modify config files**

```bash
mkdir -p docker/cameleer-clickhouse
cp docker/clickhouse-init.sql docker/cameleer-clickhouse/init.sql
cp docker/clickhouse-config.xml docker/cameleer-clickhouse/prometheus.xml
```

Create `docker/cameleer-clickhouse/users.xml` — same as original but with env-var password:

```xml
<clickhouse>
  <users>
    <default remove="remove">
    </default>

    <default>
      <profile>default</profile>
      <networks>
        <ip>::/0</ip>
      </networks>
      <password from_env="CLICKHOUSE_PASSWORD" />
      <quota>default</quota>
      <access_management>0</access_management>
    </default>
  </users>
</clickhouse>
```

Note: the `from_env` attribute makes the password configurable via the `CLICKHOUSE_PASSWORD` environment variable instead of being hardcoded.

- [ ] **Step 3: Build and verify**

```bash
docker build -t cameleer-clickhouse:test docker/cameleer-clickhouse/
docker run --rm -e CLICKHOUSE_PASSWORD=testpass cameleer-clickhouse:test clickhouse-client --version
```

Expected: ClickHouse version output, no build errors.

- [ ] **Step 4: Commit**

```bash
git add docker/cameleer-clickhouse/
git commit -m "feat: create cameleer-clickhouse image with init and config baked in"
```

---

### Task 3: Create cameleer-traefik image

**Files:**
- Create: `docker/cameleer-traefik/Dockerfile`
- Create: `docker/cameleer-traefik/entrypoint.sh`
- Create: `docker/cameleer-traefik/traefik.yml` (copy from root `traefik.yml`)
- Create: `docker/cameleer-traefik/traefik-dynamic.yml` (copy from `docker/traefik-dynamic.yml`)

- [ ] **Step 1: Copy Traefik config files**

```bash
mkdir -p docker/cameleer-traefik
cp traefik.yml docker/cameleer-traefik/traefik.yml
cp docker/traefik-dynamic.yml docker/cameleer-traefik/traefik-dynamic.yml
```

- [ ] **Step 2: Create the entrypoint script**

`docker/cameleer-traefik/entrypoint.sh`:

```bash
#!/bin/sh
set -e

CERTS_DIR="/certs"

# Skip if certs already exist (idempotent)
if [ ! -f "$CERTS_DIR/cert.pem" ]; then
  mkdir -p "$CERTS_DIR"

  if [ -n "$CERT_FILE" ] && [ -n "$KEY_FILE" ]; then
    # User-supplied certificate
    echo "[certs] Installing user-supplied certificate..."
    cp "$CERT_FILE" "$CERTS_DIR/cert.pem"
    cp "$KEY_FILE" "$CERTS_DIR/key.pem"
    if [ -n "$CA_FILE" ]; then
      cp "$CA_FILE" "$CERTS_DIR/ca.pem"
    fi
    # Validate key matches cert
    CERT_MOD=$(openssl x509 -noout -modulus -in "$CERTS_DIR/cert.pem" 2>/dev/null | md5sum)
    KEY_MOD=$(openssl rsa -noout -modulus -in "$CERTS_DIR/key.pem" 2>/dev/null | md5sum)
    if [ "$CERT_MOD" != "$KEY_MOD" ]; then
      echo "[certs] ERROR: Certificate and key do not match!"
      rm -f "$CERTS_DIR/cert.pem" "$CERTS_DIR/key.pem" "$CERTS_DIR/ca.pem"
      exit 1
    fi
    SELF_SIGNED=false
    echo "[certs] Installed user-supplied certificate."
  else
    # Generate self-signed certificate
    HOST="${PUBLIC_HOST:-localhost}"
    echo "[certs] Generating self-signed certificate for $HOST..."
    openssl req -x509 -newkey rsa:4096 \
      -keyout "$CERTS_DIR/key.pem" -out "$CERTS_DIR/cert.pem" \
      -days 365 -nodes \
      -subj "/CN=$HOST" \
      -addext "subjectAltName=DNS:$HOST,DNS:*.$HOST"
    SELF_SIGNED=true
    echo "[certs] Generated self-signed certificate for $HOST."
  fi

  # Write metadata for SaaS app to seed DB
  SUBJECT=$(openssl x509 -noout -subject -in "$CERTS_DIR/cert.pem" 2>/dev/null | sed 's/subject=//')
  FINGERPRINT=$(openssl x509 -noout -fingerprint -sha256 -in "$CERTS_DIR/cert.pem" 2>/dev/null | sed 's/.*=//')
  NOT_BEFORE=$(openssl x509 -noout -startdate -in "$CERTS_DIR/cert.pem" 2>/dev/null | sed 's/notBefore=//')

  HAS_CA=false
  [ -f "$CERTS_DIR/ca.pem" ] && HAS_CA=true
  cat > "$CERTS_DIR/meta.json" <<METAEOF
{"subject":"$SUBJECT","fingerprint":"$FINGERPRINT","selfSigned":$SELF_SIGNED,"hasCa":$HAS_CA,"notBefore":"$NOT_BEFORE","notAfter":"$NOT_AFTER"}
METAEOF

  mkdir -p "$CERTS_DIR/staged" "$CERTS_DIR/prev"
  chmod 775 "$CERTS_DIR" "$CERTS_DIR/staged" "$CERTS_DIR/prev"
  chmod 660 "$CERTS_DIR"/*.pem 2>/dev/null || true
else
  echo "[certs] Certificates already exist, skipping generation."
fi

# Start Traefik
exec traefik "$@"
```

- [ ] **Step 3: Create the Dockerfile**

```dockerfile
FROM traefik:v3
RUN apk add --no-cache openssl
COPY traefik.yml /etc/traefik/traefik.yml
COPY traefik-dynamic.yml /etc/traefik/dynamic.yml
COPY entrypoint.sh /entrypoint.sh
RUN chmod +x /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]
```

- [ ] **Step 4: Build and verify**

```bash
docker build -t cameleer-traefik:test docker/cameleer-traefik/
docker run --rm cameleer-traefik:test --version
```

Expected: Traefik version output, no build errors.

- [ ] **Step 5: Commit**

```bash
git add docker/cameleer-traefik/
git commit -m "feat: create cameleer-traefik image with cert generation and config baked in"
```

---

### Task 4: Merge bootstrap into cameleer-logto

**Files:**
- Create: `docker/cameleer-logto/logto-entrypoint.sh`
- Modify: `ui/sign-in/Dockerfile`
- Modify: `docker/logto-bootstrap.sh` (make package install conditional)

- [ ] **Step 1: Create the entrypoint wrapper**

`docker/cameleer-logto/logto-entrypoint.sh`:

```bash
#!/bin/sh
set -e

echo "[entrypoint] Seeding Logto database..."
npm run cli db seed -- --swe 2>/dev/null || true

echo "[entrypoint] Starting Logto..."
npm start &
LOGTO_PID=$!

echo "[entrypoint] Waiting for Logto to be ready..."
for i in $(seq 1 120); do
  if node -e "require('http').get('http://localhost:3001/oidc/.well-known/openid-configuration', r => process.exit(r.statusCode === 200 ? 0 : 1)).on('error', () => process.exit(1))" 2>/dev/null; then
    echo "[entrypoint] Logto is ready."
    break
  fi
  if [ "$i" -eq 120 ]; then
    echo "[entrypoint] ERROR: Logto not ready after 120s"
    exit 1
  fi
  sleep 1
done

# Run bootstrap if not already done
BOOTSTRAP_FILE="/data/logto-bootstrap.json"
if [ -f "$BOOTSTRAP_FILE" ]; then
  CACHED_SECRET=$(jq -r '.m2mClientSecret // empty' "$BOOTSTRAP_FILE" 2>/dev/null)
  CACHED_SPA=$(jq -r '.spaClientId // empty' "$BOOTSTRAP_FILE" 2>/dev/null)
  if [ -n "$CACHED_SECRET" ] && [ -n "$CACHED_SPA" ]; then
    echo "[entrypoint] Bootstrap already complete."
  else
    echo "[entrypoint] Incomplete bootstrap found, re-running..."
    /scripts/logto-bootstrap.sh
  fi
else
  echo "[entrypoint] Running bootstrap..."
  /scripts/logto-bootstrap.sh
fi

echo "[entrypoint] Logto is running (PID $LOGTO_PID)."
wait $LOGTO_PID
```

- [ ] **Step 2: Make bootstrap script package-install conditional**

In `docker/logto-bootstrap.sh`, replace line 51:

```bash
# Install jq + curl
apk add --no-cache jq curl >/dev/null 2>&1
```

With:

```bash
# Install jq + curl if not already available (deps are baked into cameleer-logto image)
if ! command -v jq >/dev/null 2>&1 || ! command -v curl >/dev/null 2>&1; then
  if command -v apk >/dev/null 2>&1; then
    apk add --no-cache jq curl >/dev/null 2>&1
  elif command -v apt-get >/dev/null 2>&1; then
    apt-get update -qq && apt-get install -y -qq jq curl >/dev/null 2>&1
  fi
fi
```

- [ ] **Step 3: Update ui/sign-in/Dockerfile**

Replace the entire Dockerfile content with:

```dockerfile
# syntax=docker/dockerfile:1

# Stage 1: Build custom sign-in UI
FROM --platform=$BUILDPLATFORM node:22-alpine AS build
ARG REGISTRY_TOKEN
WORKDIR /ui
COPY ui/sign-in/package.json ui/sign-in/package-lock.json ui/sign-in/.npmrc ./
RUN --mount=type=cache,target=/root/.npm echo "//gitea.siegeln.net/api/packages/cameleer/npm/:_authToken=${REGISTRY_TOKEN}" >> .npmrc && npm ci
COPY ui/sign-in/ .
RUN npm run build

# Stage 2: Logto with sign-in UI + bootstrap
FROM ghcr.io/logto-io/logto:latest

# Install bootstrap dependencies (curl, jq for API calls; postgresql-client for DB reads)
RUN apt-get update && apt-get install -y --no-install-recommends \
    curl jq postgresql-client \
    && rm -rf /var/lib/apt/lists/*

# Custom sign-in UI
COPY --from=build /ui/dist/ /etc/logto/packages/experience/dist/

# Bootstrap scripts
COPY docker/logto-bootstrap.sh /scripts/logto-bootstrap.sh
COPY docker/cameleer-logto/logto-entrypoint.sh /scripts/entrypoint.sh
RUN chmod +x /scripts/*.sh

ENTRYPOINT ["/scripts/entrypoint.sh"]
```

Note: This Dockerfile now requires the **repo root** as build context (not `ui/sign-in/`). The CI workflow update in Task 6 handles this.

- [ ] **Step 4: Build and verify**

```bash
mkdir -p docker/cameleer-logto
docker build -f ui/sign-in/Dockerfile -t cameleer-logto:test .
```

Expected: successful build (sign-in UI + bootstrap deps installed).

- [ ] **Step 5: Commit**

```bash
git add docker/cameleer-logto/ ui/sign-in/Dockerfile docker/logto-bootstrap.sh
git commit -m "feat: merge bootstrap into cameleer-logto image

Adds logto-entrypoint.sh that seeds DB, starts Logto, waits for health,
runs bootstrap, then keeps Logto running. Eliminates the separate
logto-bootstrap init container."
```

### Task 5: Update docker-compose.yml and clean up old files

**Files:**
- Modify: `docker-compose.yml`
- Modify: `.env.example`
- Delete: `docker/init-databases.sh`, `docker/clickhouse-init.sql`, `docker/clickhouse-users.xml`, `docker/clickhouse-config.xml`, `docker/traefik-dynamic.yml`, `docker/vendor-seed.sh`, `traefik.yml`

- [ ] **Step 1: Replace docker-compose.yml**

Replace the entire `docker-compose.yml` with:

Key changes from original:
- `traefik-certs` init container removed (merged into `cameleer-traefik` entrypoint)
- `logto-bootstrap` init container removed (merged into `cameleer-logto` entrypoint)
- All bind-mounted config files removed
- All images use `${*_IMAGE:-gitea.siegeln.net/cameleer/...}` pattern
- Logto healthcheck includes `test -f /data/logto-bootstrap.json` (passes only after bootstrap)
- `cameleer-saas` depends on `logto: service_healthy` (not `logto-bootstrap: service_completed_successfully`)
- Ports configurable via env vars (`HTTP_PORT`, `HTTPS_PORT`, `LOGTO_CONSOLE_PORT`)
- `NODE_TLS_REJECT` configurable via env var

- [ ] **Step 2: Update .env.example**

Replace the entire `.env.example` with:

```bash
# Cameleer SaaS — Environment Configuration
# Copy to .env and fill in values for production

reduced from 7 to 5. All configuration via environment variables."
```

### Task 6: Update CI workflows

**Files:**
- Modify: `.gitea/workflows/ci.yml`

- [ ] **Step 1: Add image builds for postgres, clickhouse, traefik**

Add these build steps after the existing "Build and push Logto image" step in the `docker` job:

```yaml
      - name: Build and push PostgreSQL image
        run: |
          TAGS="-t gitea.siegeln.net/cameleer/cameleer-postgres:${{ github.sha }}"
          for TAG in $IMAGE_TAGS; do
            TAGS="$TAGS -t gitea.siegeln.net/cameleer/cameleer-postgres:$TAG"
          done
          docker buildx build --platform linux/amd64 \
            $TAGS \
            --provenance=false \
            --push docker/cameleer-postgres/

      - name: Build and push ClickHouse image
        run: |
          TAGS="-t gitea.siegeln.net/cameleer/cameleer-clickhouse:${{ github.sha }}"
          for TAG in $IMAGE_TAGS; do
            TAGS="$TAGS -t gitea.siegeln.net/cameleer/cameleer-clickhouse:$TAG"
          done
          docker buildx build --platform linux/amd64 \
            $TAGS \
            --provenance=false \
            --push docker/cameleer-clickhouse/

      - name: Build and push Traefik image
        run: |
          TAGS="-t gitea.siegeln.net/cameleer/cameleer-traefik:${{ github.sha }}"
          for TAG in $IMAGE_TAGS; do
            TAGS="$TAGS -t gitea.siegeln.net/cameleer/cameleer-traefik:$TAG"
          done
          docker buildx build --platform linux/amd64 \
            $TAGS \
            --provenance=false \
            --push docker/cameleer-traefik/
```

- [ ] **Step 2: Update Logto build to use repo root context**

Change the existing "Build and push Logto image" step. Replace the `docker buildx build` line:

```yaml
      - name: Build and push Logto image
        run: |
          TAGS="-t gitea.siegeln.net/cameleer/cameleer-logto:${{ github.sha }}"
          for TAG in $IMAGE_TAGS; do
            TAGS="$TAGS -t gitea.siegeln.net/cameleer/cameleer-logto:$TAG"
          done
          docker buildx build --platform linux/amd64 \
            --build-arg REGISTRY_TOKEN="$REGISTRY_TOKEN" \
            -f ui/sign-in/Dockerfile \
            $TAGS \
            --cache-from type=registry,ref=gitea.siegeln.net/cameleer/cameleer-logto:buildcache \
            --cache-to type=registry,ref=gitea.siegeln.net/cameleer/cameleer-logto:buildcache,mode=max \
            --provenance=false \
            --push .
        env:
          REGISTRY_TOKEN: ${{ secrets.REGISTRY_TOKEN }}
```

Key change: build context is now `.` (repo root) instead of `ui/sign-in/`, and `-f ui/sign-in/Dockerfile` is added.

- [ ] **Step 3: Commit**

```bash
git add .gitea/workflows/ci.yml
git commit -m "ci: add builds for cameleer-postgres, cameleer-clickhouse, cameleer-traefik

Update Logto build to use repo root context for bootstrap script access."
```

---

### Task 7: Validate consolidated stack

**Files:** None (testing only)

- [ ] **Step 1: Start the consolidated stack**

```bash
docker compose up -d
```

- [ ] **Step 2: Verify all services start and become healthy**

```bash
docker compose ps
```

Expected: 5 services, all "Up" or "Up (healthy)". No `traefik-certs` or `logto-bootstrap` containers.

- [ ] **Step 3: Verify bootstrap completed**

```bash
docker compose exec logto cat /data/logto-bootstrap.json | jq .
```

Expected: JSON with `spaClientId`, `m2mClientId`, `m2mClientSecret`, `tradAppId`, `tradAppSecret`.

- [ ] **Step 4: Verify Traefik routing**

```bash
curl -sk https://localhost/platform/api/config | jq .
```

Expected: JSON with `logtoEndpoint`, `spaClientId`, `scopes`.

- [ ] **Step 5: Verify certs were generated**

```bash
docker compose exec traefik cat /certs/meta.json | jq .
```

Expected: JSON with `selfSigned: true`, `subject` containing localhost.

- [ ] **Step 6: Clean up test and commit any fixes**

```bash
docker compose down
```

If any issues were found and fixed, commit the fixes.

## Phase 2: Bash Installer

> **Note:** Phase 2 can be developed in parallel with Phase 1. The installer generates files and runs docker commands — it doesn't need the actual images until Task 17 (end-to-end testing).

### Task 8: Installer skeleton and utility functions

**Files:**
- Create: `installer/install.sh`

- [ ] **Step 1: Create the installer with header, constants, and utilities**

```

- [ ] **Step 2: Make executable and verify syntax**

```bash
mkdir -p installer
chmod +x installer/install.sh
bash -n installer/install.sh
```

Expected: no syntax errors.

- [ ] **Step 3: Commit**

```bash
git add installer/install.sh
git commit -m "feat(installer): scaffold install.sh with constants and utilities"
```

# Cameleer SaaS — Installation Documentation

## Installation Summary

| | |
|---|---|
| **Version** | ${VERSION} |
| **Date** | $(date -u '+%Y-%m-%d %H:%M:%S UTC') |
| **Installer** | v${CAMELEER_INSTALLER_VERSION} |
| **Install Directory** | ${INSTALL_DIR} |
| **Hostname** | ${PUBLIC_HOST} |
| **TLS** | ${tls_desc} |

## Service URLs

- **Platform UI:** ${PUBLIC_PROTOCOL}://${PUBLIC_HOST}/platform/
- **API Endpoint:** ${PUBLIC_PROTOCOL}://${PUBLIC_HOST}/platform/api/
EOF

  if [ "$LOGTO_CONSOLE_EXPOSED" = "true" ]; then
    echo "- **Logto Admin Console:** ${PUBLIC_PROTOCOL}://${PUBLIC_HOST}:${LOGTO_CONSOLE_PORT}" >> "$f"
  fi

  cat >> "$f" << 'EOF'

## First Steps

1. Open the Platform UI in your browser
2. Log in with the admin credentials from `credentials.txt`
3. Create your first tenant via the Vendor console
4. The platform will provision a dedicated server instance for the tenant

## Architecture

| Container | Purpose |
|---|---|
| `traefik` | Reverse proxy, TLS termination, routing |
| `postgres` | PostgreSQL database (SaaS + Logto + tenant schemas) |
| `clickhouse` | Time-series storage (traces, metrics, logs) |
| `logto` | OIDC identity provider + bootstrap |
| `cameleer-saas` | SaaS platform (Spring Boot + React) |

Per-tenant `cameleer-server` and `cameleer-server-ui` containers are provisioned dynamically when tenants are created.

## Networking

EOF

  cat >> "$f" << EOF
| Port | Service |
|---|---|
| ${HTTP_PORT} | HTTP (redirects to HTTPS) |
| ${HTTPS_PORT} | HTTPS (main entry point) |
EOF

  if [ "$LOGTO_CONSOLE_EXPOSED" = "true" ]; then
    echo "| ${LOGTO_CONSOLE_PORT} | Logto Admin Console |" >> "$f"
  fi

  if [ -n "$MONITORING_NETWORK" ]; then
    cat >> "$f" << EOF

### Monitoring

Services are connected to the \`${MONITORING_NETWORK}\` Docker network with Prometheus labels for auto-discovery.
EOF
  fi

  cat >> "$f" << EOF

## TLS

**Mode:** ${tls_desc}
EOF

  if [ "$TLS_MODE" = "self-signed" ]; then
    cat >> "$f" << 'EOF'

The platform generated a self-signed certificate on first boot. To replace it:
1. Log in as admin and navigate to **Certificates** in the vendor console
2. Upload your certificate and key via the UI
3. Activate the new certificate (zero-downtime swap)
EOF
  fi

  cat >> "$f" << 'EOF'

## Data & Backups

| Docker Volume | Contains |
|---|---|
| `pgdata` | PostgreSQL data (tenants, licenses, audit) |
| `chdata` | ClickHouse data (traces, metrics, logs) |
| `certs` | TLS certificates |
| `bootstrapdata` | Logto bootstrap results |

### Backup Commands

```bash
# PostgreSQL
docker compose exec postgres pg_dump -U cameleer cameleer_saas > backup.sql

# ClickHouse
docker compose exec clickhouse clickhouse-client --query "SELECT * FROM cameleer.traces FORMAT Native" > traces.native
```

## Upgrading

Re-run the installer with a new version:

```bash
curl -sfL https://install.cameleer.io | bash -s -- --install-dir DIR --version NEW_VERSION
```

The installer preserves your `.env`, credentials, and data volumes. Only the compose file and images are updated.

## Troubleshooting

| Issue | Command |
|---|---|
| Service not starting | `docker compose logs SERVICE_NAME` |
| Bootstrap failed | `docker compose logs logto` |
| Routing issues | `docker compose logs traefik` |
| Database issues | `docker compose exec postgres psql -U cameleer -d cameleer_saas` |

## Uninstalling

```bash
# Stop and remove containers
docker compose down

# Remove data volumes (DESTRUCTIVE)
docker compose down -v

# Remove install directory
rm -rf INSTALL_DIR
```
EOF

  # Replace INSTALL_DIR placeholder
  sed -i "s|INSTALL_DIR|${INSTALL_DIR}|g" "$f"

  log_info "Generated INSTALL.md"

### Task 16: Re-run and upgrade logic

**Files:**
- Modify: `installer/install.sh`

- [ ] **Step 1: Add re-run menu and handlers**

Append:

```bash
# --- Re-run and upgrade ---

show_rerun_menu() {

### Task 17: Main function and end-to-end testing

**Files:**
- Modify: `installer/install.sh`

- [ ] **Step 1: Add main function**

Append:

```bash
# --- Main ---

main() {
  parse_args "$@"

  print_banner

  # Load config sources (CLI already loaded via parse_args)
  if [ -n "$CONFIG_FILE_PATH" ]; then
    load_config_file "$CONFIG_FILE_PATH"
  fi
  load_env_overrides

  # Check for existing installation
  detect_existing_install
  if [ "$IS_RERUN" = true ]; then
    show_rerun_menu
    handle_rerun
  fi

  # Prerequisites
  check_prerequisites

  # Auto-detect defaults
  auto_detect

  # Interactive prompts (unless silent)
  if [ "$MODE" != "silent" ]; then
    select_mode
    if [ "$MODE" = "expert" ]; then
      run_expert_prompts
    else
      run_simple_prompts
    fi
  fi

  # Merge remaining defaults and validate
  merge_config
  validate_config

  # Generate passwords for any empty values
  generate_passwords

  # Create install directory
  mkdir -p "$INSTALL_DIR"

  # Copy custom certs if provided
  if [ "$TLS_MODE" = "custom" ]; then
    copy_certs
  fi

  # Generate configuration files
  generate_env_file
  generate_compose_file
  write_config_file

  # Pull and start
  docker_compose_pull
  docker_compose_up

  # Verify health
  verify_health

  # Generate output files
  generate_credentials_file
  generate_install_doc

  # Print results
  print_credentials
  print_summary
}

main "$@"
```

- [ ] **Step 2: Verify the complete script has no syntax errors**

```bash
bash -n installer/install.sh
```

- [ ] **Step 3: Test silent mode with defaults (dry-run inspection)**

Create a test that generates files without actually pulling/starting:

```bash
# Temporarily disable docker operations for testing
bash -c '
  source <(sed "s/docker_compose_pull/# &/;s/docker_compose_up/# &/;s/verify_health/# &/" installer/install.sh | head -n -2)
  INSTALL_DIR="/tmp/cameleer-test"
  MODE="silent"
  merge_config
  generate_passwords
  mkdir -p "$INSTALL_DIR"
  generate_env_file
  generate_compose_file
  write_config_file
  generate_credentials_file
  echo "=== Generated .env ==="
  cat "$INSTALL_DIR/.env"
  echo ""
  echo "=== Generated compose (first 20 lines) ==="
  head -20 "$INSTALL_DIR/docker-compose.yml"
  rm -rf /tmp/cameleer-test
'
```

Expected: .env and docker-compose.yml generated with default values.

- [ ] **Step 4: Full end-to-end test (requires Phase 1 complete and images available)**

```bash
bash installer/install.sh --silent --install-dir /tmp/cameleer-e2e --public-host localhost
# Wait for health checks to pass
# Verify: curl -sk https://localhost/platform/api/config
# Cleanup: cd /tmp/cameleer-e2e && docker compose down -v && rm -rf /tmp/cameleer-e2e
```

- [ ] **Step 5: Commit**

```bash
git add installer/install.sh
git commit -m "feat(installer): add main function and complete install.sh

Fully functional bash installer with simple/expert/silent modes,
idempotent re-run, health verification, and documentation generation."
```

## Phase 3: PowerShell Installer

### Task 18: PowerShell implementation

**Files:**
- Create: `installer/install.ps1`

The PowerShell script mirrors the bash installer's structure and logic exactly. It produces identical output files (docker-compose.yml, .env, credentials.txt, INSTALL.md, cameleer.conf).

- [ ] **Step 1: Create install.ps1**

Create `installer/install.ps1` with the same function structure as install.sh, adapted for PowerShell idioms:

| Bash function | PowerShell equivalent | Key differences |
|---|---|---|
| `generate_password` | `New-SecurePassword` | Uses `[System.Security.Cryptography.RandomNumberGenerator]` |
| `parse_args` | `param()` block | PowerShell native parameter handling |
| `prompt` / `prompt_password` | `Read-Host` / `Read-Host -AsSecureString` | Native PowerShell prompts |
| `check_prerequisites` | `Test-Prerequisites` | Uses `Get-Command`, `Test-NetConnection` |
| `auto_detect` | `Get-AutoDetectedDefaults` | Uses `[System.Net.Dns]::GetHostEntry()` |
| `generate_compose_file` | `New-ComposeFile` | Uses here-strings (`@'...'@`) |
| `generate_env_file` | `New-EnvFile` | Same format, `Set-Content` |
| `docker_compose_pull/up` | `Invoke-DockerCompose` | Same docker commands |
| `verify_health` | `Test-ServiceHealth` | Same docker exec + curl checks |
| `check_port_available` | `Test-PortAvailable` | Uses `Test-NetConnection -Port` |

Key structural differences for PowerShell:
- Parameters declared via `param()` block (replaces manual arg parsing)
- Docker socket default: `//./pipe/docker_engine` (Windows named pipe)
- Password generation: `[System.Security.Cryptography.RandomNumberGenerator]::GetBytes(24)` → Base64
- Port checking: `Test-NetConnection -ComputerName localhost -Port $port`
- Hostname detection: `[System.Net.Dns]::GetHostEntry([System.Net.Dns]::GetHostName()).HostName`
- Color output: `Write-Host -ForegroundColor` instead of ANSI escape codes
- Here-strings for templates: `@'...'@` (literal) and `@"..."@` (expanding)

The compose template content must be identical to the bash version — same YAML, same variable references, same conditional sections. Use the same `>> $file` append pattern with PowerShell here-strings.

```powershell
#Requires -Version 5.1
[CmdletBinding()]
param(
    [switch]$Silent,
    [switch]$Expert,
    [string]$Config,
    [string]$InstallDir,
    [string]$PublicHost,
    [string]$PublicProtocol,
    [string]$AdminUser,
    [string]$AdminPassword,
    [ValidateSet('self-signed', 'custom')]
    [string]$TlsMode,
    [string]$CertFile,
    [string]$KeyFile,
    [string]$CaFile,
    [string]$PostgresPassword,
    [string]$ClickhousePassword,
    [int]$HttpPort,
    [int]$HttpsPort,
    [int]$LogtoConsolePort,
    [string]$LogtoConsoleExposed,
    [string]$VendorEnabled,
    [string]$VendorUser,
    [string]$VendorPassword,
    [string]$MonitoringNetwork,
    [string]$Version,
    [string]$ComposeProject,
    [string]$DockerSocket,
    [string]$NodeTlsReject,
    [switch]$Reconfigure,
    [switch]$Reinstall,
    [switch]$ConfirmDestroy,
    [switch]$Help
)

$InstallerVersion = "1.0.0"
$DefaultVersion = "latest"
$Registry = "gitea.siegeln.net/cameleer"

# ... implement all functions following the bash structure ...
# Each function mirrors its bash equivalent exactly.
# The generated files (.env, docker-compose.yml, etc.) must be identical.
```

Implement each function following the bash structure. The implementing agent should read `installer/install.sh` and translate each function to PowerShell, maintaining identical behavior and output.

- [ ] **Step 2: Verify PowerShell syntax**

```powershell
$null = [System.Management.Automation.PSParser]::Tokenize((Get-Content installer/install.ps1 -Raw), [ref]$null)
```

Or on Linux with PowerShell Core:

```bash
pwsh -Command "& { \$null = [System.Management.Automation.PSParser]::Tokenize((Get-Content 'installer/install.ps1' -Raw), [ref]\$null); Write-Host 'Syntax OK' }"
```

- [ ] **Step 3: Commit**

```bash
git add installer/install.ps1
git commit -m "feat(installer): add PowerShell installer for Windows

Mirrors install.sh structure and produces identical output files.
Uses native PowerShell idioms for parameters, prompts, and crypto."
```

## Task Dependencies

```
Tasks 1,2,3,4 ─── can run in parallel (independent images)
         │
    Task 5 ─────── depends on 1-4 (compose update)
    Task 6 ─────── depends on 1-4 (CI update)
         │
    Task 7 ─────── depends on 5,6 (stack validation)

Tasks 8-16 ────── can run in parallel with Phase 1
                  (installer generates files, doesn't need images)
         │
    Task 17 ────── depends on Task 7 + Task 16
                   (E2E test needs working images + complete installer)

    Task 18 ────── depends on Task 16
                   (PowerShell mirrors completed bash)
```

## Follow-up (out of scope)

- Bake `docker/server-ui-entrypoint.sh` into the `cameleer-server-ui` image (separate repo)
- Set up `install.cameleer.io` distribution endpoint
- Create release automation (tag → publish installer scripts to distribution endpoint)
- Add `docker-compose.dev.yml` overlay generation for the installer's expert mode
