defiQUG 1fb7266469 Add Oracle Aggregator and CCIP Integration
- Introduced Aggregator.sol for Chainlink-compatible oracle functionality, including round-based updates and access control.
- Added OracleWithCCIP.sol to extend Aggregator with CCIP cross-chain messaging capabilities.
- Created .gitmodules to include OpenZeppelin contracts as a submodule.
- Developed a comprehensive deployment guide in NEXT_STEPS_COMPLETE_GUIDE.md for Phase 2 and smart contract deployment.
- Implemented Vite configuration for the orchestration portal, supporting both Vue and React frameworks.
- Added server-side logic for the Multi-Cloud Orchestration Portal, including API endpoints for environment management and monitoring.
- Created scripts for resource import and usage validation across non-US regions.
- Added tests for CCIP error handling and integration to ensure robust functionality.
- Included various new files and directories for the orchestration portal and deployment scripts.

SSH Commands from Nginx Proxy to Backend VMs

Backend VM IPs

IP Address Region Region Code
10.1.1.4 Central US cus
10.2.1.4 East US eus
10.3.1.4 East US 2 eus2
10.4.1.4 West US wus
10.5.1.4 West US 2 wus2

SSH Command Format

ssh -o StrictHostKeyChecking=no besuadmin@<IP>

Individual Commands

Central US (cus)

ssh -o StrictHostKeyChecking=no besuadmin@10.1.1.4

East US (eus)

ssh -o StrictHostKeyChecking=no besuadmin@10.2.1.4

East US 2 (eus2)

ssh -o StrictHostKeyChecking=no besuadmin@10.3.1.4

West US (wus)

ssh -o StrictHostKeyChecking=no besuadmin@10.4.1.4

West US 2 (wus2)

ssh -o StrictHostKeyChecking=no besuadmin@10.5.1.4

Batch Commands

Test connectivity to all VMs

for IP in 10.1.1.4 10.2.1.4 10.3.1.4 10.4.1.4 10.5.1.4; do
  echo "=== Testing $IP ==="
  ssh -o StrictHostKeyChecking=no -o ConnectTimeout=5 besuadmin@$IP 'echo Connected successfully' || echo "  Connection failed"
done

Execute command on all VMs

for IP in 10.1.1.4 10.2.1.4 10.3.1.4 10.4.1.4 10.5.1.4; do
  echo "=== Executing on $IP ==="
  ssh -o StrictHostKeyChecking=no besuadmin@$IP '<your-command-here>'
done

Setting Up SSH Keys (If Not Already Configured)

Step 1: Generate SSH key on Nginx proxy (if not exists)

ssh besuadmin@20.160.58.99
ssh-keygen -t rsa -b 4096 -f ~/.ssh/id_rsa -N ""
cat ~/.ssh/id_rsa.pub

Step 2: Copy public key to each backend VM

# From Nginx proxy, copy public key to each VM
for IP in 10.1.1.4 10.2.1.4 10.3.1.4 10.4.1.4 10.5.1.4; do
  ssh-copy-id -o StrictHostKeyChecking=no besuadmin@$IP
done

Step 3: Alternative - Manual key copy via Azure Run Command

# Get public key from Nginx proxy
PUBLIC_KEY=$(ssh besuadmin@20.160.58.99 "cat ~/.ssh/id_rsa.pub")

# Add to each VM's authorized_keys
for REGION in "cus" "eus" "eus2" "wus" "wus2"; do
  RG="az-p-${REGION}-rg-comp-001"
  VM=$(az vm list --resource-group "$RG" --query "[0].name" -o tsv)
  az vm run-command invoke \
    --resource-group "$RG" \
    --name "$VM" \
    --command-id RunShellScript \
    --scripts "echo '$PUBLIC_KEY' >> ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys"
done

Notes

  • Username: besuadmin (as configured in Terraform)
  • StrictHostKeyChecking: Disabled to avoid host key verification prompts
  • ConnectTimeout: 5 seconds recommended for batch operations
  • Network: VNet peerings are configured, so connectivity should work once SSH keys are set up

Troubleshooting

Permission denied (publickey)

  • SSH keys not configured between Nginx proxy and backend VMs
  • Solution: Set up SSH keys using the steps above

Connection refused

  • VM not running or port 22 blocked
  • Solution: Check VM status and NSG rules

Host key verification failed

  • Use -o StrictHostKeyChecking=no flag
  • Or manually accept host keys: ssh-keyscan <IP> >> ~/.ssh/known_hosts
