I’m having real troubles getting Rancher HA running ( 3 Hosts )
- All ports open both ingress and egress ( 0.0.0.0/0 ) on all hosts ( hosts are in the SAME AWS region but separate AZs )
- External database which HAS connections established
- 16GB RAM on the hosts
- 50GB volumes on the hosts
- I’ve followed the specific documentation around setting up HA - have run the generated script against the latest container and keep seeing errors :
time=“2016-11-08T11:52:12Z” level=info msg=“Waiting for 3 host(s) to be active” component=cert
time=“2016-11-08T11:52:14Z” level=info msg=“Waiting for 3 host(s) to be active” component=cert
time=“2016-11-08T11:52:17Z” level=fatal msg=“Failed while waiting for 3 host(s) to be active: Get http://172.17.0.1:18080/v1/projects/1a7/hosts?state=active: read tcp 172.17.0.1:52114->172.17.0.1:18080: read: connection reset by peer” component=service
Can someone tell me please what rancher is doing on boot up
I assume there is cross container networking at the host level but what containers are trying to communicate with each other - is there a list ?
Also is there any cross host communication going on - if so what ?
The documentation is generally pretty good, however when you get down to this level I can’t find anything to help me out so any guidance would be much appreciated. This has been burning me for the best part of a week now, and I really don’t want to use another Orchestrator
