Discovery Service

Global configuration

The Discovery Global Configuration, acts as central configuration, shared by all consumers of the Discovery service. Configuration setting such as discovery timeouts and heartbeat intervals can be defined here and will therefore be consistent across consumers.

global:
  discovery:
    enabled: true
    useProxy: true
    localReg: true
    registry: "kxi-discovery-service:8761"
    heartbeatSecs: 10
    leaseExpirySecs: 30
    callTimeoutSecs: 10
    maxPeriodRetrySecs: 20
    refreshServicesSecs: 30

enabled

Variable	Type	Example	Default
enabled	bool	true	false

Enable the use of Service Discovery in all services within the KX Insights Platform where applicable.

registry

Variable	Type	Example	Default
registry	string	kxi-discovery-service:8761	""

Target address of the Discovery registry. This is an optional entry to override the default value created during installation. Set localReg to false and provide the new registry location value to use a Discovery Service external to your deployment. This information will bubble into all services utilizing Service Discovery within the KX Insights Platform.

useProxy

Variable	Type	Example	Default
useProxy	bool	true	true

Enable or disable the use of the discovery proxy instance.

With registry undefined, localReg set to true and useProxy set to true, helpers will build a url for registry targeting the Discovery Proxy service. If false, will target the Discovery registry service.

localReg

Variable	Type	Example	Default
localReg	bool	true	false

Flag to indicate that the Discovery Registry is being deployed as part of this release.

With registry undefined, and localReg set to true, helpers will build a url for registry. If false, will create a registry url from the registry variable, which may be an empty string.

heartbeatSecs

Variable	Type	Example	Default
heartbeatSecs	long	10	30

Defines the rate at which KX Insights Platform services will heartbeat to the Discovery registry.

leaseExpirySecs

Variable	Type	Example	Default
leaseExpirySecs	long	30	90

Defines the period of time (in seconds) the Discovery registry will wait before evicting a Service after a failed heartbeat.

callTimeoutSecs

Variable	Type	Example	Default
callTimeoutSecs	long	10	10

Set the timeout value (in seconds) for kurl calls to the Discovery registry/proxy service. Used by all services to ensure timely responses between themselves and the Discovery Registry

maxPeriodRetrySecs

Variable	Type	Example	Default
maxPeriodRetrySecs	long	20	30

Maximum period of time (in seconds) a service will wait between connection attempts to the Discovery Registry.

refreshServicesSecs

Variable	Type	Example	Default
refreshServicesSecs	long	30	30

Period of time (in seconds) each service will refresh its local cache of services from the registry.

Service configuration

Service configuration allows the user to override defaults provided for the Discovery service.
