Okera leverages Kubernetes for cluster creation and port management. The following document outlines the expected port assignments.
Okera Internal Ports
The following ports are assumed to be open between cluster nodes and are required for proper cluster creation and management as of version 0.6. SSH (port 22) is not necessary for Okera usage but may be required for node troubleshooting and administration. These ports are not customizable.
|443||Kubernetes Master Communication|
|6443||Kubernetes API Server|
|8085||Okera Master Host Port|
Okera Default Service Ports
The following list is a collection of default Okera service ports. These ports can be changed during Okera setup activities and in Okera environment configuration.
Note that Kubernetes requires a number of ports to be accessible for internal cluster activities. The default port range is the lowest bound service port + the next 2000 ports or the difference between the lowest bound port and the highest bound port; whatever range is largest.
Lowest port: 7180 (Default Okera HMS Port)
Highest port: 7187 (Default Kubernetes WebUI)
Effective Kubernetes port range: 7180-9180
Custom Setting Example:
Lowest port: 2500 (Custom Okera HMS Port)
Highest port: 10000 (Custom Okera WebUI)
Effective Kubernetes port range: 2500-10000 (7500 ports)
|7181||Okera Planner WebUI|
|7184||Okera REST Server|
