I’m trying to setup rancher on AWS.
My current setup is the following :
- 1 host with rancher/server:0.51.0 provisioned with docker-machine
- 3 hosts with rancher/agent provisioned via the rancher UI.
The hosts live in a VPC, in the same subnet and can communicate (SG allows all traffic inside the SG)
When everything is up, the cross host networking doesn’t seems to work. When two containers in a network are on the same host, they can communicate whether when they are on different ones they can’t.
Here is the infrastructure page :
I don’t know where the 172.31.25.41 ip address comes from : it’s not a private or public ip… Sometimes, two hosts have the same IP !
I tryed to re-register the agent by forcing the CATTLE_IP to the private’s VPC IP but it doesn’t work either.
Where can I try to have some logs about the IPSec networking to try to guess what’s going wrong ? Any advice ?
