Purpose of cbgateway node in cloudbreak

mliem — Wed, 14 Sep 2016 21:15:46 GMT

Hello,

Can someone briefly explain the purpose of the cbgateway node when using cloudbreak?

- Any recommendations around minimum aws instance sizes to satisfy its requirements?

- Can this node be turned into an edge node with client libraries?

Thanks,

Hi @mliem,

From Cloudbreak version 1.4 we don't use cbgateway node. It's function was running Ambari, in newer versions of Cloudbreak one designated hostgroup - with one node - will be the Ambari server node. You can configure it when you start a cluster (under 'Choose Blueprint' tab).

Valid for Release 1.3

Any recommendations around minimum aws instance sizes to satisfy its requirements?

We use m3.large for this node with 100GB mount used for logs and postgres database of ambari-server.

Can this node be turned into an edge node with client libraries?

No, this node does not have ambari-agent installed it only have ambari-server and its database.

"Any recommendations around minimum aws instance sizes to satisfy its requirements?" It is hardly depends on for example your cluster size and load. I suggest to ask Ambari experts, they know much more about Ambari server system requirements.
