ec2 discovery


(Barak Yaish) #1

Hi,

I've 3 nodes on ec2, each of them run 0.90.9. With default config, none of
them discover each other. Now I want 2 of them to form a cluster, so I
installed on those 2 nodes aws-cloud plugin, changed the related
configuration and restarted. The 2 nodes indeed discovered each other as
expected, but also the 3rd node... Only after changing the cluster name of
that 3rd node, it left the cluster. Is it OK that node without aws-cloud
plugin got discovered by the others?

Thanks!

As I understand it, the ec2 plugin simply does ec2 API calls to list
instances, filtered as per your config. It plays no actual part in the
connectivity or clustering part - just discovery.
So yes it makes sense what you saw.
