• All containers have default routes configured
• No interfaces in DOWN state

3. Gateway Connectivity

✅ 97-100% Success Rate

• 32-33 containers can successfully reach gateway (192.168.11.1)
• 0-1 container may have transient issues (resolves on restart)
• All critical containers have reliable gateway connectivity

4. Inter-Container Connectivity

✅ 100% Success Rate

All tested connectivity paths are working:

• ✅ DBIS PostgreSQL → Order PostgreSQL
• ✅ DBIS PostgreSQL → DBIS Redis

Configuration Status

Hookscript Configuration

✅ Applied to All 33 Containers

Hookscript: local:snippets/configure-network.sh

Function:

• Automatically configures network on container start (post-start phase)
• Extracts IP and gateway from Proxmox config
• Configures network interface inside container
• Brings interface UP and adds IP/routes

Status: All containers have hookscript set for persistent network configuration

Issues Resolved

Issue 1: Missing Hookscripts ✅ RESOLVED

Problem: 14 containers did not have hookscript set, preventing automatic network configuration.

Resolution: Applied hookscript to all 33 containers.

Issue 2: Network Interfaces Down ✅ RESOLVED

Problem: Containers with missing hookscript had DOWN network interfaces.

Resolution:

1. Applied hookscript to all containers
2. Manually configured network interfaces
3. Verified all interfaces are UP

Issue 3: Gateway Connectivity Issues ✅ MOSTLY RESOLVED

Problem: Some containers could not reach gateway due to DOWN interfaces.

Resolution:

• Fixed network interfaces for all affected containers
• Restarted containers to apply configuration
• 32-33 containers now have reliable gateway connectivity
