I am running API Gateway 10.15.0.7.266 on Azure Kubernetes Services (AKS) deployed using Helm charts with the image from containers.softwareag.com. I have added the following configuration for the Control Plane agent:

cp-agent.yml:
----
enabled: true
runtimeConfig:
  runtimeName: "API_Gateway_THES_CONFIG"
  deploymentType: "PRIVATE_CLOUD"
  description: "A demo deployment of SAG API Gateway CONFIG environment"
  heartBeatIntervalInSeconds: 30
  metricsSynchIntervalInSeconds: 30
  assetSynchIntervalInSeconds: 30
  region: "azure-westeurope"
  location: "Hamburg"
  host: "http://config-apigateway-ui.azuredemo-softwareag.com/"
  tags:
     - thes-demo
     - config
  capacity:
     value: 1000
     units: "per second"
controlPlaneConfig:
  controlPlaneURL: "https://presalesdemos.apicp-az-eu.webmethods.io"
  username: "thomas.hesse@softwareag.com"
  password: "***"

But the API Gateway does not show up in the Control Plane. In server.log, I found the following NullPointerException:

2023-08-14 16:27:17 GMT [YAI.0015.8889I] (tid=297) [default][azure-demo-apigateway-78d78df5bd-rjc6r]  Control plane agent  not configured with environment properties.So trying to read from file.

com.softwareag.apigateway.is.init.ISPackageManager.startup(ISPackageManager.java:218)
apigateway.startup(apigateway.java:57)
...

PFA the full server.log file.

I also tried with just the mandatory parameters:

cp-agent.yml:
----
enabled: true
runtimeConfig:
  runtimeName: "API_Gateway_THES_CONFIG"
  # deploymentType: "PRIVATE_CLOUD"
  # description: "A demo deployment of SAG API Gateway CONFIG environment"

controlPlaneConfig:
  controlPlaneURL: "https://presalesdemos.apicp-az-eu.webmethods.io"
  username: "thomas.hesse@softwareag.com"
  password: "***"

Same result. What am I doing wrong? How can I increase the log level for the agent? Maybe the user does not have enough rights in the Control Plane?

In trace mode, the log does not reveal much more:

FYI: I managed to make it work using environment variables instead of cp-agent.yml ConfigMap. But it would be much more convenient (and closer to Kubernetes best practices, I believe) to inject the configuration using ConfigMap. Why is that not working?

The agentConfig key is missing in the YAML file. It should be as `below.

cp-agent.yml:
----
agentConfig:
  enabled: true
  runtimeConfig:
    runtimeName: "API_Gateway_THES_CONFIG"
    # deploymentType: "PRIVATE_CLOUD"
    # description: "A demo deployment of SAG API Gateway CONFIG environment"
    # heartBeatIntervalInSeconds: 30
    # metricsSynchIntervalInSeconds: 30
    # assetSynchIntervalInSeconds: 30
    # region: "azure-westeurope"
    # location: "Hamburg"
    # host: "http://config-apigateway-ui.azuredemo-softwareag.com/"
    # tags:
    #    - thes-demo
    #    - config

@MadhavanKidambiVaradan Thanks for your help! It is working fine with the agentConfig key. Thanks!
