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 two deployment types: Docker (containerized) and Native (installed directly on the OS, no Docker required).

Deployment Types

	Docker	Native
Runtime	Wallarm container on Docker engine	Wallarm NGINX module installed directly on the OS
Artifacts	Docker static binaries + Wallarm image (from Git repo or local)	Wallarm all-in-one installer (meganode.wallarm.com)
Multi-node on one host	✅ Yes (unique ports)	⚠️ One node per host (single system NGINX)
Directory	docker/	native/
Requires Docker	✅ (installed automatically)	❌ Never installed
Best for	LXC/containers, multiple nodes, air-gapped	Simple single VM, minimal footprint, no containers

Features

• Automated Preflight Checks – Validates system readiness, network connectivity, and resource availability (per deployment type)
• Smart Artifact Management – Git Repositorys-first approach with local fallback support (Docker type)
• Multiple Node Support (Docker) – Deploy multiple Wallarm instances on the same VM with unique port configurations
• Interactive Configuration – User-friendly prompts for cloud region, ports, token, and upstream applications
• Comprehensive Validation – Network tests, port availability checks, and deployment verification
• Persistence & Management – Automatic service creation (systemd/OpenRC/SysV), start scripts, and health monitoring
• Post‑Deployment Reconfiguration – Easily update trusted proxy IPs and change operation mode without redeploying
• Clean Uninstallation – Safe removal of containers, packages, and configuration files

Prerequisites

System Requirements

• Operating System: Linux (Ubuntu 20.04+, CentOS/RHEL 8+, Debian 11+, Alpine)
• Architecture: x86_64 (amd64) or aarch64 (arm64) for native; x86_64 for Docker artifacts
• 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 or wget: For downloading scripts and artifacts
• sudo: For package installation and system configuration
• systemd, OpenRC or sysvinit: For service management

Quick Start

1. Download the Scripts

Use the wrapper script to download all necessary tools. You will be asked to select the deployment type (docker or native):

curl -fsSL "https://git.sechpoint.app/customer-engineering/wallarm/raw/branch/main/setup.sh" | bash

To select non-interactively (e.g. for automation):

DEPLOYMENT_TYPE=native curl -fsSL "https://git.sechpoint.app/customer-engineering/wallarm/raw/branch/main/setup.sh" | bash

The setup script downloads the shared library and makes executable:

• common/wallarm-lib.sh – Shared functions for both deployment types
• docker/wallarm-ct-check.sh – Preflight validation (Docker)
• docker/wallarm-ct-deploy.sh – Main deployment script (Docker)
• docker/wallarm-ct-reconfigure.sh – Modify configuration after deployment (Docker)
• docker/wallarm-ct-uninstall.sh – Remove a Wallarm node (Docker)
• native/wallarm-ct-check.sh – Preflight validation (Native)
• native/wallarm-ct-deploy.sh – Main deployment script (Native)
• native/wallarm-ct-reconfigure.sh – Modify configuration after deployment (Native)
• native/wallarm-ct-uninstall.sh – Remove a Wallarm node (Native)
• native/wallarm-native.sh – Unified single-script manager for the Wallarm Native Node (connector mode)

2. Run Preflight Check

# Docker deployment
./docker/wallarm-ct-check.sh

# Native deployment
./native/wallarm-ct-check.sh

The preflight check will:

• Verify system compatibility (OS, architecture, init system)
• Test network connectivity to Wallarm cloud endpoints
• Validate artifact availability (Docker: Git repo / local files; Native: all-in-one installer)
• Validate resource availability
• Generate a .env file with results

3. Deploy Wallarm Node

# Docker deployment
sudo ./docker/wallarm-ct-deploy.sh

# Native deployment
sudo ./native/wallarm-ct-deploy.sh

The deployment script will:

1. Read preflight check results
2. Prompt for configuration (ports, upstream application, Wallarm token, trusted proxies)
3. Docker: Install Docker, download and load the Wallarm image, configure and start the container
4. Native: Download and run the Wallarm all-in-one installer, configure NGINX, reload and verify
5. Verify deployment with health checks

Required Information Before Deployment

To ensure a smooth deployment, have the following information ready before starting the script:

Item	Description	Example	Notes
Inbound Port	The port on which the Wallarm node will listen for incoming HTTP traffic.	80 (HTTP) or 8080	Must be unused on the server. If port 80 is already in use, choose another.
Application Server (Upstream) IP/Hostname	The IP address or hostname of the backend application that Wallarm will forward traffic to.	192.168.1.100 or app.internal.local	Must be reachable from the Wallarm node. If the application runs on the same physical machine, do not use 127.0.0.1 – use the host's actual IP.
Application Server Port	The port on which the backend application listens.	8080	Must be open and listening.
Wallarm Node Token	A token obtained from the Wallarm Console when creating a new "Wallarm node".	base64_encoded_string	Copy it exactly. It will be pasted during the deployment process.
Trusted Proxy IPs/CIDRs (Optional)	The IP address(es) of any load balancers, firewalls, or CDNs that sit in front of the Wallarm node and set the X-Real-IP header.	10.0.0.10 or 192.168.0.0/24	If the node is directly accessible from the internet (no proxy in front), leave empty. Multiple entries can be space-separated.
Wallarm Cloud Region	Which Wallarm cloud to use – US or EU.	US or EU	The script will test connectivity to both and only show reachable ones.
Operation Mode (Optional, can be changed later)	The initial operation mode. monitoring only logs attacks, block actively blocks.	monitoring (recommended for first deployment)	The script defaults to monitoring. You can change it later using the reconfigure script.

Additional Preparation Steps

• Ensure the backend application is running and reachable from the Wallarm server. Test with telnet <upstream_ip> <upstream_port>.
• If you plan to use a custom domain, be prepared to configure DNS to point to the server's public IP (or the load balancer) – the Wallarm node itself does not require a domain for basic setup.
• If the server is behind a firewall, open the inbound port (e.g., 80) to allow traffic from the internet or the load balancer.

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 scripts configure the first three headers automatically. You must manually add X-Forwarded-Host: "$host" to your existing firewall/ingress configuration.

Docker Deployment (docker/)

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)

Native Deployment (native/)

The native deployment installs Wallarm directly on the operating system without Docker, using the official Wallarm all-in-one installer:

• The installer is downloaded from https://meganode.wallarm.com/ (version configurable via the WALLARM_VERSION environment variable, default 6.12.7)
• It automatically detects your OS and NGINX version, adds the Wallarm repositories, installs wallarm-node + the NGINX dynamic module, and registers the node
• Node registration is performed by the installer itself in batch mode (using your Wallarm token)
• The node configuration is written to /opt/wallarm/etc/wallarm/node.yaml
• The system NGINX is configured with a wallarm-<instance>.conf server block in /etc/nginx/conf.d/

Notes on native deployment:

• One node per host: native uses the system NGINX, so multiple Wallarm nodes on one host are not supported (unlike Docker). Use unique ingress ports only if you run a single node alongside other services.
• The deploy script keeps a copy of the generated NGINX config in /opt/wallarm/<instance-name>/nginx.conf and a log of the nginx -t test.
• curl http://127.0.0.8/wallarm-status reports Wallarm module statistics after deployment.

Example: Version Pinning

WALLARM_VERSION=6.12.7 sudo ./native/wallarm-ct-deploy.sh

Unified Node Manager (native/wallarm-native.sh)

For the Wallarm Native Node product (go-node, connector-server mode, no NGINX module), the repository provides a unified single-script manager. It manages multiple isolated nodes under /opt/wallarm/nodes/ via a systemd template unit (wallarm-node@<name>.service):

sudo ./native/wallarm-native.sh --preflight     # preflight checks only
sudo ./native/wallarm-native.sh --install       # interactive multi-node install (parallel)
sudo ./native/wallarm-native.sh --config --node node1 --address 0.0.0.0:9090
sudo ./native/wallarm-native.sh --remove --node node2
sudo ./native/wallarm-native.sh --status [NODE] # node status (all or one)

Key characteristics:

• Preflight checks run automatically before --install and are available standalone via --preflight (root, systemd, architecture, required commands, installer + Wallarm cloud connectivity, disk/memory, listen-port availability)
• Per-node isolated directories (etc/, var/log/, var/run/), with the Wallarm token stored in a chmod 600 env file
• All-in-one installer is downloaded from https://repo.wallarm.com/linux/wallarm-native-node/latest/all-in-one/ (override with WALLARM_INSTALLER_URL, architecture with WALLARM_INSTALLER_ARCH)
• Parallel installation with per-node install logs (install.log)

Note: This script targets the Wallarm Native Node (connector mode). The native/wallarm-ct-*.sh scripts target the NGINX-module native deployment. Both are no-Docker options; choose the one that matches your Wallarm product.

Reconfiguration Script (wallarm-ct-reconfigure.sh)

After deployment, you may need to adjust:

• Trusted proxy IPs/CIDRs – When the network topology changes (new load balancer, CDN, firewall)
• Operation mode – Switch from monitoring to block after verifying correct operation

The reconfigure script safely modifies the configuration of an existing instance, creates a backup, and applies the changes (Docker: restarts the container; Native: tests and reloads NGINX).

Usage:

# Docker
sudo ./docker/wallarm-ct-reconfigure.sh

# Native
sudo ./native/wallarm-ct-reconfigure.sh

It will detect installed instances, show current settings, and guide you through the changes.

Uninstallation (wallarm-ct-uninstall.sh)

To completely remove a Wallarm node:

# Docker: remove container/image and optionally Docker
sudo ./docker/wallarm-ct-uninstall.sh

# Native: remove NGINX config, Wallarm packages, and node data
sudo ./native/wallarm-ct-uninstall.sh

Artifact Sources

Docker Deployment (Priority Order)

The Docker deployment uses a smart fallback approach for artifact retrieval:

1. Primary Source: Git Repositorys

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

2. Secondary Source: Local Directories

   • docker/binaries/ – Docker static binaries (docker-29.2.1.tgz)
   • docker/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

Native Deployment (Source)

The native deployment downloads the Wallarm all-in-one installer directly from https://meganode.wallarm.com/. No Docker artifacts are required. Current versions are listed at node-artifact-versions.

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\|: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/

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. Native Installer Fails

# The all-in-one installer logs its output to the terminal and to files
# Check the current version at https://docs.wallarm.com/updating-migrating/node-artifact-versions/

# Verify node registration
ls -la /opt/wallarm/etc/wallarm/node.yaml

# Check Wallarm module status
curl http://127.0.0.8/wallarm-status

6. 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 (Docker) / ~/logs/wallarm-check-native.log (Native)
• Deployment: ~/logs/wallarm-deployment.log (Docker) / ~/logs/wallarm-deployment-native.log (Native)
• Docker Container Logs: /opt/wallarm-<instance-name>/container.log
• NGINX Logs (Native): /var/log/nginx/error.log
• System Logs: /var/log/syslog or /var/log/messages

Security Considerations

Network Security

• Use firewall rules to restrict access to monitoring endpoints
• 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 services
• Implement proper secret management for Wallarm tokens

Monitoring & Auditing

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

Maintenance

Regular Tasks

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

Version Updates

When updating Wallarm node version:

1. Docker: Pull new image from Git Repositorys or official registry, stop existing container, deploy new container with updated image, verify functionality before removing old container
2. Native: Set WALLARM_VERSION to the new version and re-run the deploy script, or follow the official upgrade guide
