Table 4-1 SCP Configuration Parameters

Attribute Name DataType Range Default Value Mandatory(M)/Optional(O)/Conditional(C) User can change? Description
Global: Configuration used by all the micro services
domain 
<string>
Labels can be letter a-z, number 0-9, hyphen (-). Hyphen cannot be first character. Label combined with dot (.) forms domain svc.cluster.local M Y Option to configure the Service Domain of the K8 cluster.
To know cluster domain one can use command : 
kubectl -n kube-system get configmap kubeadm-config -o yaml | grep clusterName
clusterDomain 
<string>
 Labels can be letter a-z, number 0-9, hyphen (-). Hyphen cannot be first character. Label combined with dot (.) forms domain cluster.local M Y Option to configure the Domain of the K8 cluster. Ideally, it is domain attribute value by removing "svc."
ingressGWAvailable 
<boolean>
 true/false false O Y If ingress gateway is available then set ingressGWAvailable flag to true and provide ingress gateway IP and Port in publicSignalingIP and publicSignalingPort respectively, else set to false.

Note: If ingressGWAvailable flag is true then service type for scp-worker will be set to ClusterIP, otherwise it will be set to LoadBalancer.

publicSignalingIPSpecified 
<boolean>
true/false false O Y Option to enable/disable Loadbalancer IP configuration statically for Signaling interface. This parameter must be set to true if SCP needs to be used with ingress gateway. publicSignalingIP and publicSignalingPort must be set to ingress gateway IP and Port in this case. If ingressGWAvailable is set to false then setting it true will cause SCP-Worker service to be exposed as LB and ingress gateway will not be used.
publicSignalingIP 
<IPv4 Address>
 Valid IPV4 address as per RFC 791 N/A C Y Option to configure static Signaling Loadbalancer IP. Configured value will be used only if signalingloadbalanceripenabled is configured as "true".
publicSignalingPort 
<integer>
 Min- 0 , Max-65535 8000 M Y Option to configure Signaling Port
adminport 
<integer>
Min- 0 , Max-65535 8001 M Y Option to configure Admin Port (used for debugging purpose)
imageRepository

ocspf-registry.us.oracle.com:5000/ocscp

M Y User need to set imageRepository to the repository where SCP images are loaded.
scpInfo SCP Profile that will be used to by SCP register with OCNRF (Primary First and Secondary if primary Fails). Registration of SCP services is optional and can be governed vis the nfService.nfServiceStatus flag. If nfServiceStatus is set to registered than that service will get registered with OCNRF. In case of anything other than registered (i.e. SUSPENDED/UNDISCOVBERABLE) that service will not get registered with OCNRF. In any one of the case the service mentioned can be used locally by SCP as long as its present in SCP Profile. In case a service is omitted from SCP profile, SCP will neither register nor be able to use that service (or in case of SDS-APP service the sds-app service is not even deployed)

scpc-soothsayer: Configuration specific to Soothsayer Micro Service
systemOptions 
trafficPolicy:
      connectionPool:
        http:
          idleTimeout: 3600s
        tcp:
          tcpKeepalive:
            probes: 9
            time: 180s
            interval: 60s

tcpKeepalive.probes - Maximum number of keepalive probes to send without response before deciding the connection is dead.

tcpKeepalive.time - The time duration that a connection must be idle before keep-alive probes start being sent.

tcpKeepalive.interval - The time duration between keep-alive probes.

  O Y HTTP Idle timeout for upstream connections. TCP keep alive settings for upstream connections. All 3 (probe, time and interval) are required if tcpkeepalive is enabled. Following the scenarios while using these parameters:
  1. Only HTTP IdleTimeout is configured. idleTimeout must be set to a value less than kube-proxy timeout value so that before kube-proxy silently discards connection, connection gets terminated gracefully by HTTP.
  2. Only TCP keepalive is configured. TCP keepalive must be set to a value less than kube-proxy timeout value so that before kube-proxy silently discards connection, connection gets terminated by TCP RESET if no ACK is received within the defined interval.
  3. Both TCP keepalive and HTTP idleTimeout are configured. In this case idleTimeout can be more than kube-proxy timeout but TCP keepalive must be less than kube-proxy timeout. TCP keepalive keeps refreshing the connection at kube-proxy and if no HTTP request is received within the idleTimeout period, connection will get gracefully terminated by HTTP.

Logging level

The description of each logging level is as mentioned below:

Table 4-2 Logging level

Logging Level Description
ALL All levels including custom levels.
DEBUG Designates fine-grained informational events that are most useful to debug an application.
INFO Designates informational messages that highlight the progress of the application at coarse-grained level.
WARN Designates potentially harmful situations.
ERROR Designates error events that might still allow the application to continue running.
FATAL Designates very severe error events that will presumably lead the application to abort.
OFF The highest possible rank and is intended to turn off logging.
TRACE Designates finer-grained informational events than the DEBUG.
