The below steps will guide you through the process of integrating the APM Insight .NET agent into your Kubernetes deployment using init containers. 

1. Create a secret for the Applications Manager Apminsight license key in your application namespace
   
   1. kubectl create secret generic s247licensekey --fromliteral=S247_LICENSE_KEY=YOUR_LICENSE_KEY_HERE
      

   Note:
   Replace YOUR_LICENSE_KEY_HERE with the appropriate apminsight license key value from the Applications Manager  console.


2. Create an empty volume mount that will be used to copy the agent files during the InitContainers process.
   

   Example:
   

   1. volumeMounts: 
   2.       - name: s247dotnetcoreagent



3. Include the following InitContainers command and mount the volume in both initContainer and your application container in your helm chart/deployment YAML file:
   

   1. kind: Deployment
   2.   spec:
   3.     containers:
   4.       - name: dotnet-app
   5.         image: microsoft/dotnet-samples:aspnetapp 
   6.         volumeMounts:
   7.           - mountPath: /home/APMDotNetAgent
   8.             name: s247dotnetcoreagent 
   9.     initContainers:
   10.       - name: init-site24x7-agent
   11.         image: site24x7/apminsight-dotnetagent:latest
   12.         command: ['cp', '-r', '/opt/site24x7/APMDotNetAgent', '/home'] 
   13.         volumeMounts: 
   14.           - name: s247dotnetcoreagent 
   15.             mountPath: /home/APMDotNetAgent



4. Add the following environment variables to application containers.
   

   1. spec:  
   2.   containers:
   3.     - name: dotnet-app
   4.       env:    
   5.         - name: S247_LICENSE_KEY
   6.           valueFrom:
   7.             secretKeyRef: 
   8.               name: s247licensekey
   9.               key: S247_LICENSE_KEY
   10.         - name: CORECLR_ENABLE_PROFILING
   11.           value: "1"
   12.         - name: CORECLR_PROFILER
   13.           value: "{9D363A5F-ED5F-4AAC-B456-75AFFA6AA0C8}"
   14.         - name: DOTNETCOREAGENT_HOME
   15.           value: "/home/APMDotNetAgent"
   16.         - name: CORECLR_PROFILER_PATH_64 
   17.           value: "/home/APMDotNetAgent/x64/libClrProfilerAgent.so"
   18.         - name: CORECLR_PROFILER_PATH_32
   19.           value: "/home/APMDotNetAgent/x86/libClrProfilerAgent.so" 
   20.         - name: DOTNET_STARTUP_HOOKS
   21.           value: "/home/APMDotNetAgent/netstandard2.0/DotNetAgent.Loader.dll"
   22.         - name: MANAGEENGINE_COMMUNICATION_MODE
   23.           value: "direct"
   24.         - name: SITE24X7_APP_NAME
   25.         value: "YOUR_APM_APPLICATION_NAME"
       
   26.         - name: APMINSIGHT_HOST
   27.         value: "APPLICATIONS_MANAGER_URL"

   Note:

   Replace your application name with YOUR_APM_APPLICATION_NAME value, and apm url with APPLICATIONS_MANAGER_URL.
