Discovery Service configuration parameters
Discovery Service configuration parameters
#
Zowe runtime configuration parametersAs an application developer who wants to run Zowe, set the following parameters during the Zowe runtime configuration by modifying the <Zowe install directory>/components/discovery/bin/start.sh
file:
#
API ML configurationapiml.discovery.userid
The Discovery service in HTTP mode protects it's endpoints with basic authentication instead of client certificate. This parameter specifies the userid. The default value is
eureka
.apiml.discovery.password
This parameter specifies the password for the basic authentication used by the Discovery Service in HTTP mode. The default value is
password
.apiml.discovery.allPeersUrls
This parameter contains the list of URLs of the Discovery Service in case of multiple instances of the service on different host. Example:
apiml: discovery: allPeersUrls: https://localhost2:10021/eureka/,https://localhost3:10031/eureka/
Note: Each URL within the list must be separated by a comma.
apiml.discovery.staticApiDefinitionsDirectories
The static definition directories can be specified as a parameter at startup and will be scanned by the Discovery Service. These directories contains the definitions of static services. Example:
```yaml apiml: discovery: staticApiDefinitionsDirectories: config/local/api-defs;config/local2/api-defs
#
Eureka configurationThe Discovery Service contains a configuration for implementing the client-side service discovery and for defining a Eureka Server for service registry. Such configuration is shown below:
eureka: instance: hostname: ${apiml.service.hostname} ipAddress: ${apiml.service.ipAddress} port: ${server.port} securePort: 0 nonSecurePortEnabled: true securePortEnabled: false preferIpAddress: ${apiml.service.preferIpAddress} statusPageUrl: http://${apiml.service.hostname}:${apiml.service.port}/application/info healthCheckUrl: http://${apiml.service.hostname}:${apiml.service.port}/application/health client: registerWithEureka: true fetchRegistry: true region: default serviceUrl: defaultZone: ${apiml.discovery.allPeersUrls} server: useReadOnlyResponseCache: false
eureka.client.registerWithEureka If we make this property as true then while the server starts the inbuilt client will try to register itself with the Eureka server.
eureka.client.registerWithEureka The inbuilt client will try to fetch the Eureka registry if we configure this property as true.
eureka.client.serviceUrl.defaultZone A fallback value that provides the Eureka service URL for any client that does not express a preference (in other words, it is a useful default).
More information about the other Eureka parameters can be found in the Spring Cloud Netflix Eureka documentation.
