ZooKeeper ports
ZooKeeper uses three ports, one for client access, and two for internal ZooKeeper use.
-
ZooKeeper Client Portd,
2181: ZooKeeper clients—in this case CloudBees CD server hosts—connect to ZooKeeper ensemble hosts on the ZooKeeper client port.Every CloudBees CD server host needs to be able to connect to the ZooKeeper client port on every ZooKeeper ensemble host. No other hosts need access to this port.
-
ZooKeeper Leader Port
3888: Used internally by ZooKeeper. Every ZooKeeper ensemble host needs to be able to connect to the ZooKeeper leader port on all other ZooKeeper ensemble hosts. No other hosts need access to this port. -
ZooKeeper Peer Port
2888: Used internally by ZooKeeper. Every ZooKeeper ensemble host needs to be able to connect to the ZooKeeper peer port on all other ZooKeeper ensemble hosts. No other hosts need access to this port.
Call routing
In network topologies where it is not possible to route traffic directly between all hosts in the system, CloudBees CD agents can be configured as gateways to handle the routing of repository server and CloudBees Software Delivery Automation server traffic.
Because the network topology is not known in advance, the webserver and repository servers always use their local agent to route traffic to the repository and CloudBees Software Delivery Automation server endpoints.
The CloudBees CD agents use the same port, 7800, and forward calls on to the server port 8443 or repository port 8200 on the destination host, as appropriate.
