Affected Area¶

• DevOps / Infrastructure
• Server Management
• Network & Security
• Container Management

---

Description¶

This task involves setting up core infrastructure components to improve secure access, centralized container management, and network connectivity across all systems.

The scope includes:

• SSH Tunnel setup for secure remote access
• Portainer setup for container monitoring and management
• VPN configuration for secure internal network access

---

SSH Tunnel Setup¶

---

Objective¶

Establish a secure SSH Tunnel to access internal services (DB, APIs, dashboards) without exposing them publicly.

---

Requirements¶

• Configure SSH tunneling between:

  • Local machine ↔ Remote server

• Allow secure port forwarding

---

Expected Behavior¶

• Internal services accessible via localhost
• No direct public exposure of services
• Secure encrypted communication

---

Sample Command¶

ssh -L 5432:localhost:5432 user@server-ip

---

Use Cases¶

• Access private database
• Secure API debugging
• Internal service access

---

Portainer Setup (Centralized Container Management)¶

---

Objective¶

Deploy Portainer in the main server and connect all Docker environments for centralized monitoring.

---

Requirements¶

• Install Portainer on main server

• Connect:

  • Local Docker
  • Remote Docker hosts

• Enable container monitoring and control

---

Expected Features¶

• Container status monitoring
• Logs access
• Resource usage tracking
• Container start/stop/redeploy
• Multi-node management

---

Sample Setup¶

docker volume create portainer_data

docker run -d \
  -p 9000:9000 \
  -p 9443:9443 \
  --name portainer \
  --restart=always \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v portainer_data:/data \
  portainer/portainer-ce

---

Outcome¶

• Single dashboard for all systems
• Easier DevOps operations
• Reduced manual server access

---

VPN Configuration¶

---

Objective¶

Set up a secure Virtual Private Network (VPN) to connect all servers and users within a private network.

---

Requirements¶

• Configure VPN server

• Allow secure access to:

  • Internal services
  • Databases
  • Admin panels

---

Recommended VPN Options¶

• WireGuard (Lightweight & fast)
• OpenVPN (Widely used & stable)

---

Expected Behavior¶

• Only authorized users can access internal systems
• Encrypted communication between nodes
• No need to expose services publicly

---

Example Use Cases¶

• Secure remote developer access
• Internal system communication
• Protect admin endpoints

---

Business Impact¶

• Improved security for infrastructure
• Centralized container management
• Secure remote access for developers
• Reduced risk of unauthorized access
• Better operational efficiency

---

Proposed Implementation Plan¶

Phase	Task
Phase 1	Setup SSH tunnel access
Phase 2	Deploy Portainer on main server
Phase 3	Connect all Docker nodes to Portainer
Phase 4	Setup VPN server
Phase 5	Configure user access & testing
