Wallarm Deployment System

A comprehensive solution for deploying Wallarm filtering nodes on virtual machines or bare metal servers. This system provides automated deployment, preflight checks, and management of Wallarm security nodes with support for multiple instances on the same server.

Features

• Automated Preflight Checks - Validates system readiness, network connectivity, and resource availability
• Smart Artifact Management - GitLab-first approach with local fallback support
• Multiple Node Support - Deploy multiple Wallarm instances on the same VM with unique port configurations
• Interactive Configuration - User-friendly prompts for cloud region, ports, tokens, and upstream applications
• Comprehensive Validation - Network tests, port availability checks, and deployment verification
• Persistence & Management - Automatic service creation, start scripts, and health monitoring
• Clean Uninstallation - Safe removal of containers, images, and configuration files

Prerequisites

System Requirements

• Operating System: Linux (Ubuntu 20.04+, CentOS/RHEL 8+, Debian 11+)
• Architecture: x86_64 (amd64)
• Memory: Minimum 2GB RAM (4GB recommended for production)
• Storage: Minimum 10GB free disk space
• Network: Outbound connectivity to Wallarm cloud endpoints

Software Dependencies

• Bash: Version 4.0+ (included with most Linux distributions)
• curl: For downloading artifacts and connectivity testing
• sudo: For Docker installation and system configuration
• systemd or sysvinit: For service management

Quick Start

1. Download the Scripts

# Download the preflight check script
curl -sL "https://git.sechpoint.app/customer-engineering/wallarm/-/raw/main/wallarm-ct-check.sh" > wallarm-ct-check.sh
chmod +x wallarm-ct-check.sh

# Download the deployment script
curl -sL "https://git.sechpoint.app/customer-engineering/wallarm/-/raw/main/wallarm-ct-deploy.sh" > wallarm-ct-deploy.sh
chmod +x wallarm-ct-deploy.sh

# Download the uninstall script (optional)
curl -sL "https://git.sechpoint.app/customer-engineering/wallarm/-/raw/main/wallarm-ct-uninstall.sh" > wallarm-ct-uninstall.sh
chmod +x wallarm-ct-uninstall.sh

2. Run Preflight Check

./wallarm-ct-check.sh

The preflight check will:

• Verify system compatibility (OS, architecture, init system)
• Test network connectivity to Wallarm cloud endpoints
• Check for existing Docker installations
• Validate resource availability
• Generate a .env file with results

3. Deploy Wallarm Node

./wallarm-ct-deploy.sh

The deployment script will:

1. Read preflight check results
2. Prompt for configuration (ports, upstream application, Wallarm token)
3. Install Docker if not present
4. Download and load Wallarm Docker image
5. Configure and start the Wallarm container
6. Verify deployment with health checks

Detailed Usage

Workflow Overview

1. Preflight Check → Deployment → Verification → Management

Configuration Requirements

Wallarm Node Token

Before deployment, you need a Wallarm Node Token from the Wallarm Console:

• Create Token: Navigate to Wallarm Console → Nodes → Create node
• Token Format: Base64 encoded string (alphanumeric with +, /, =, -, _)
• Documentation: Official Wallarm Documentation

Header Configuration for Firewalls/Ingress Controllers

To ensure proper IP address detection and metadata forwarding, configure your firewall or ingress controller to include these headers:

proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Host $host;

Note: The deployment script configures the first three headers automatically. You must manually add X-Forwarded-Host: "$host" to your existing firewall/ingress configuration.

Multiple Node Deployment on Same VM

You can deploy multiple Wallarm nodes on the same virtual machine by:

1. Unique Port Configuration: Each instance must use unique ingress and monitoring ports

   • Default ingress port: 80 (configurable during deployment)
   • Monitoring port: ingress_port + 10 (auto-calculated)
   • Example: Instance 1 (80/90), Instance 2 (8080/8090), Instance 3 (8888/8898)

2. Instance Naming: Each deployment generates a unique instance name

   • Format: wallarm-<hostname>-<date>-<random>
   • Example: wallarm-server1-20250324-ab3c

3. Isolated Configuration: Each instance has its own:

   • Docker container with unique name
   • Configuration directory (/opt/wallarm/<instance-name>/)
   • Port binding and network namespace
   • Log files and start scripts

Resource Considerations for Multiple Nodes:

• Add 500MB RAM per additional Wallarm instance
• Each instance requires ~2GB disk space
• Consider CPU allocation (1 vCPU core per 2-3 instances for moderate traffic)

Artifact Sources (Priority Order)

The system uses a smart fallback approach for artifact retrieval:

1. Primary Source: GitLab Repository

• URL: https://git.sechpoint.app/customer-engineering/wallarm
• Contains: Docker binaries and Wallarm images with SHA256 checksums
• Benefits: Version control, access control, audit trail

2. Secondary Source: Local Directories

• ./binaries/ - Docker static binaries (docker-29.2.1.tgz)
• ./images/ - Wallarm Docker images (wallarm-node-6.11.0-rc1.tar.gz)
• Benefits: Air-gapped environments, faster deployment

3. Tertiary Source: Current Directory

• Any docker-*.tgz or wallarm-node-*.tar.gz files in script location
• Benefits: Ad-hoc deployments, testing scenarios

4. Fallback Source: Internal Proxy Servers

• Original infrastructure URLs (with embedded credentials)
• Used only when other sources are unavailable

Troubleshooting

Common Issues

1. Preflight Check Fails

# Check detailed errors
cat .env

# Verify network connectivity manually
curl -I https://api.wallarm.com
curl -I https://us1.api.wallarm.com

# Check system compatibility
uname -m
cat /etc/os-release

2. Deployment Fails - Port Conflicts

# Check for listening ports
sudo ss -tlnp | grep ':80\|:90\|:8080'

# Find process using port
sudo lsof -i :80

# Configure different ports during deployment

3. Wallarm Token Issues

# Verify token format (should be base64)
echo "your_token" | base64 -d 2>/dev/null | base64

# Get new token from Wallarm Console
# https://docs.wallarm.com/admin-en/installation-docker-en/

4. Docker Installation Problems

# Check Docker service status
sudo systemctl status docker

# Verify Docker group membership
groups $USER

# Test Docker without sudo
docker run --rm hello-world

5. Header Configuration Warnings

Ensure your upstream firewall/load balancer includes:

• X-Real-IP: "$remote_addr"
• X-Forwarded-For: "$proxy_add_x_forwarded_for"
• X-Forwarded-Proto: "$scheme"
• X-Forwarded-Host: "$host"

Log Files

• Preflight Check: ~/logs/wallarm-check.log
• Deployment: ~/logs/wallarm-deployment.log
• Container Logs: /opt/wallarm/<instance-name>/container.log
• System Logs: /var/log/syslog or /var/log/messages

Security Considerations

Network Security

• Use firewall rules to restrict access to monitoring ports (default: 90, 190, 290, etc.)
• Consider VPN or private networking for management interfaces
• Implement rate limiting for ingress ports

Access Control

• Restrict sudo access to deployment scripts
• Use separate service accounts for Wallarm containers
• Implement proper secret management for Wallarm tokens

Monitoring & Auditing

• Enable Docker logging driver with rotation
• Monitor container resource usage
• Regular security updates for Docker and host OS

Maintenance

Regular Tasks

1. Log Rotation: Configure logrotate for container logs
2. Docker Updates: Periodically update Docker engine
3. Image Updates: Check for new Wallarm node versions
4. Backup: Regular backup of configuration directories

Version Updates

When updating Wallarm node version:

1. Pull new image from GitLab or official registry
2. Stop existing container
3. Deploy new container with updated image
4. Verify functionality before removing old container
