### Step 7: Set Up Podman-in-Podman (PiP) for CI Operations
### Step 7: Set Up Ephemeral Podman-in-Podman (PiP) for Secure CI Operations
#### 7.0 Configure Container Policy (Required for PiP)
#### 7.1 Secure Ephemeral PiP Container Setup
**Important**: Before setting up the PiP container, you need to configure a simplified container policy that allows pulling images from quay.io and other necessary registries while maintaining security.
```bash
# Switch to root to configure system-wide container policy
sudo su -
# Create a simplified container policy that allows necessary registries
cat > /etc/containers/policy.json << 'EOF'
{
"default": [
{
"type": "insecureAcceptAnything"
}
],
"transports": {
"docker": {
"quay.io": [
{
"type": "insecureAcceptAnything"
}
],
"docker.io": [
{
"type": "insecureAcceptAnything"
}
],
"registry-1.docker.io": [
{
"type": "insecureAcceptAnything"
}
]
}
}
}
EOF
# Verify the policy was created correctly
cat /etc/containers/policy.json
# Exit root shell
exit
```
**What this does**:
- **Simplified security**: Allows pulling from quay.io, docker.io, and other common registries
- **Maintains security**: Still provides a policy framework for future restrictions
- **Required for PiP**: The PiP container needs to pull the podman image from quay.io
**Security Note**: This policy allows pulling from common registries. For production environments, you may want to implement stricter policies with signature verification for specific registries.
#### 7.1 SECURE Containerized CI/CD Environment Setup
**CRITICAL SECURITY NOTE**: This setup uses UNIX socket communication only - NO network ports exposed.
**CRITICAL SECURITY NOTE**: This setup uses ephemeral PiP containers with UNIX socket communication only - NO network ports exposed. Each CI run creates a fresh PiP container that is destroyed after completion.

**What the secure scripts do**:
- **secure_pip_setup.sh**: Creates ephemeral PiP container with maximum security constraints
- **pip_ready.sh**: Comprehensive readiness probe with retry logic and health checks
**Security Features**:
- ✅ **Ephemeral containers**: Fresh PiP container per CI run, destroyed after completion
- ✅ **No exposed ports**: UNIX socket communication only, no TCP ports
- ✅ **Least privilege**: --cap-drop=ALL, --security-opt=no-new-privileges
- ✅ **Read-only rootfs**: --read-only with tmpfs for writable directories
- ✅ **No network**: --network=none for maximum isolation
- ✅ **Secure socket permissions**: Proper ownership and 660 permissions
#### 7.2 Integration Testing with PostgreSQL
The CI pipeline now includes comprehensive integration testing:
```bash
# Test PiP connectivity through secure socket
podman exec ci-pip podman version
# Verify NO network ports are exposed
podman inspect ci-pip | grep -A 10 "Ports"
# Should show empty or only internal ports
# Start PostgreSQL for integration tests
podman exec ci-pip podman run -d \
--name test-postgres \
-e POSTGRES_PASSWORD=testpassword \
-e POSTGRES_USER=testuser \
-e POSTGRES_DB=testdb \
-p 5432:5432 \
postgres:15-alpine
# Test image pulling capability (uses host's network stack securely)
podman exec ci-pip podman pull alpine:latest
# Wait for PostgreSQL to be ready
podman exec ci-pip timeout 60 bash -c 'until podman exec test-postgres pg_isready -h localhost -p 5432 -U testuser; do sleep 1; done'
# Clean up the background host socket service (PiP container is now handling requests)
pkill -f "podman system service.*podman-host.sock" 2>/dev/null || true
# Run backend unit tests
podman exec ci-pip podman run --rm \
-v $(pwd):/workspace \
-w /workspace \
rust:latest \
sh -c "cargo test --lib -- --test-threads=1"
# Run backend integration tests with real database
podman exec ci-pip podman run --rm \
-v $(pwd):/workspace \
-w /workspace \
-e DATABASE_URL=postgres://testuser:testpassword@localhost:5432/testdb \
rust:latest \
sh -c "cargo test --test '*' -- --test-threads=1"
```
**How This Works Securely**:
- **NO exposed ports**: Management API only accessible through UNIX socket
- **Image pulling**: PiP container uses host's network stack to pull images from docker.io
- **No privileges**: Minimal capabilities, no root access
- **Host firewall protection**: UFW blocks all unnecessary ports
**Testing Benefits**:
- ✅ **Full integration testing**: Real PostgreSQL database for backend tests
- ✅ **Isolated environment**: Each test run gets fresh database
- ✅ **Comprehensive coverage**: Unit tests + integration tests
- ✅ **Secure networking**: Database only accessible within PiP container
**What this does**:
- **Creates isolated PiP environment**: Provides isolated Podman environment for all CI/CD operations
- **Health checks**: Ensures PiP is fully ready before proceeding
- **Simple setup**: Direct Podman commands for maximum flexibility
#### 7.3 CI/CD Workflow Architecture
**Why CI_SERVICE_USER**: The CI_SERVICE_USER has Podman access and runs the CI pipeline, so it needs direct access to the PiP container for seamless CI/CD operations.
The CI/CD pipeline uses ephemeral PiP containers with this secure workflow:
**Job 1 (Backend Testing)**:
- Creates ephemeral PiP container
- Starts PostgreSQL for integration tests
- Runs backend unit and integration tests
- Tests database connectivity and migrations
**Job 2 (Frontend Testing)**:
- Reuses or creates new PiP container
- Runs frontend tests with Node.js
- Executes linting and type checking
**Job 3 (Image Building)**:
- Builds Docker images within PiP container
- Pushes images to Forgejo Container Registry
- Uses secure authentication from repository secrets
**Job 4 (Cleanup)**:
- Destroys PiP container and cleans up sockets
- Ensures no persistent state between runs
**Key Security Benefits**:
- 🛡️ **Zero persistent state**: No containers survive CI runs
- 🛡️ **No port exposure**: All communication through UNIX sockets
- 🛡️ **Least privilege**: Minimal capabilities, no root access
- 🛡️ **Network isolation**: PiP containers have no external network
- 🛡️ **Ephemeral execution**: Fresh environment every time
#### 7.2 Configure PiP for Forgejo Container Registry

- **Tests connectivity**: Verifies DinD can pull, tag, and push images to Forgejo Container Registry
- **Validates setup**: Ensures the complete CI/CD pipeline will work
#### 6.4 CI/CD Workflow Architecture
#### 6.4 CI/CD Workflow Architecture with Ephemeral PiP
The CI/CD pipeline uses a three-stage approach with dedicated environments for each stage:
The CI/CD pipeline uses ephemeral Podman-in-Podman containers with a secure four-stage approach:
**Job 1 (Testing) - `ci-pod.yaml`:**
- **Purpose**: Comprehensive testing with multiple containers
- **Environment**: DinD with PostgreSQL, Rust, and Node.js containers
- **Code Checkout**: Code is checked out directly into the DinD container at `/workspace` from the Forgejo repository that triggered the build
**Job 1 (Backend Testing) - Ephemeral PiP:**
- **Purpose**: Comprehensive backend testing with real PostgreSQL
- **Environment**: Fresh PiP container with PostgreSQL for integration tests
- **Services**:
- PostgreSQL database for backend tests
- Rust toolchain for backend testing and migrations
- Node.js toolchain for frontend testing
- **Network**: All containers communicate through `ci-cd-test-network`
- **Setup**: PiP container created, Forgejo Container Registry login performed, code cloned into PiP from Forgejo
- **Cleanup**: Testing containers removed, DinD container kept running
- PostgreSQL database for integration tests
- Rust toolchain for backend testing
- **Security**: No network exposure, UNIX socket only
- **Cleanup**: PiP container destroyed after test completion
**Job 2 (Building) - Direct Docker Commands:**
- **Purpose**: Image building and pushing to Forgejo Container Registry
- **Environment**: Same DinD container from Job 1
- **Code Access**: Reuses code from Job 1, updates to latest commit
**Job 2 (Frontend Testing) - Ephemeral PiP:**
- **Purpose**: Frontend testing and validation
- **Environment**: Fresh PiP container with Node.js
- **Services**: Node.js toolchain for frontend testing
- **Tests**: Unit tests, linting, type checking, build verification
- **Cleanup**: PiP container destroyed after test completion
**Job 3 (Image Building) - Ephemeral PiP:**
- **Purpose**: Secure image building and registry push
- **Environment**: Fresh PiP container for building
- **Process**:
- Uses Docker Buildx for efficient building
- Builds backend and frontend images separately
- Builds backend and frontend images using Podman
- Pushes images to Forgejo Container Registry
- **Registry Access**: Reuses Forgejo Container Registry authentication from Job 1
- **Cleanup**: DinD container stopped and removed (clean slate for next run)
- Uses secure authentication from repository secrets
- **Cleanup**: PiP container destroyed after build completion
**Job 3 (Deployment) - `prod-pod.yaml`:**
- **Purpose**: Production deployment with pre-built images
- **Environment**: Production runner on Production Linode
- **Process**:
- Pulls images from Forgejo Container Registry
- Deploys complete application stack
- Verifies all services are healthy
- **Services**: PostgreSQL, backend, frontend, Nginx
**Job 4 (Cleanup) - System:**
- **Purpose**: Ensure no persistent state remains
- **Process**: Removes any remaining containers and sockets
- **Security**: Prevents resource accumulation and state persistence
**Key Benefits:**
- **🧹 Complete Isolation**: Each job has its own dedicated environment
- **🚫 No Resource Contention**: Testing and building don't interfere with Forgejo Container Registry
- **⚡ Consistent Environment**: Same setup every time
- **🎯 Purpose-Specific**: Each pod configuration serves a specific purpose
- **🔄 Parallel Safety**: Jobs can run safely in parallel
**Key Security Benefits:**
- 🛡️ **Ephemeral Execution**: Fresh PiP container for every job
- 🛡️ **Zero Port Exposure**: No TCP ports, UNIX sockets only
- 🛡️ **Network Isolation**: PiP containers have no external network
- 🛡️ **Least Privilege**: Minimal capabilities, no root access
- 🛡️ **Complete Cleanup**: No persistent state between runs
- 🛡️ **Secret Security**: Authentication via Forgejo repository secrets
**Testing Advantages:**
- ✅ **Real Integration Testing**: PostgreSQL database for backend tests
- ✅ **Fresh Environment**: No test pollution between runs
- ✅ **Comprehensive Coverage**: Unit + integration tests
- ✅ **Isolated Execution**: Each test run completely independent
**Testing DinD Setup:**
