[Fiware-lab-help] Help Multiple Orion Instances on FiLab

[Sándor Laki]

Dear Gioacchino,

I've forwarded your question to the Orion developers, and they will 
answer if it is possible to launch two Orion instances in the same VM or 
not.

However, if you create two VMs with Orion in the same virtual network, 
and assign a floating IP to one of them. You can simply add a forwarding 
rule to the machine having the public IP address so that you can reach 
the second orion instance (running in the VM with local address only) 
through the public ip.

For that:
1. add the following iptables rules on the VM with public IP address:
iptables -t nat -A PREROUTING -p tcp -m tcp --dport 1027 -j DNAT 
--to-destination <private IP of the second orion vm>:1026
iptables -t nat -A POSTROUTING -p tcp -m tcp --dport 1027 -j MASQUERADE

2. and enable packet forwarding:
sysctl -w net.ipv4.ip_forward=1

3. After that add a new security rule in the cloud portal so that port 
1027 would be open.
After that the second Orion can be accessed on <public ip>:1027

Another option to use a proxy like PEPProxy or something similar on the 
machine with public ip:

I hope it helps you,
Best,
Sandor
