Onboarding the .Net CD Agent

These steps outline the onboarding steps needed on the environment, with the CD agent, added to each component that builds up the Application Under Test.

Configuration steps

  1. Download an Agent Token from the dashboard and make it available to each component configured with our agent.

    • This can be done by placing it in a file accessible to the agent or through an environment variable directly or through a secret manager.

  2. Download the CD agent and make it available to each component by copying it in, downloading it during startup, or mounting an external volume containing the agent. Please refer to the dedicated section below for details.

  3. Create an “Integration Build Lab ID” entry of type “CD only” in the dashboard for the tested application (see picture on the right).

    • Do so in the settings of the SeaLights dashboard, under 'Cockpit & Onboarding → Integration Build Labs → CD Only'

    • The lab ID from this integration build entry needs to be provided to the CD agent through an environment variable.

  4. Add the CD agent to your environment to attach it as a Profiler to your Application Under Test.

  5. Set the relevant parameters and/or environment variables to be used (See samples below)

When the application is up and running and the Sealights CD Agent configured, you can see it is properly running from the Cockpit -> Live Agents Monitor screen.

Windows

wget -nv -O sealights-dotnet-agent-linux.tar.gz https://agents.sealights.co/dotnetcore/latest/sealights-dotnet-agent-linux-self-contained.tar.gz
mkdir sl-dotnet-agent && tar -xzf ./sealights-dotnet-agent-linux.tar.gz --directory ./sl-dotnet-agent
echo "[Sealights] .NetCore Agent version is: `cat ./sl-dotnet-agent/version.txt`"
iwr -OutFile sealights-dotnet-agent.zip -UseBasicParsing -Uri https://agents.sealights.co/dotnetcore/latest/sealights-dotnet-agent-windows-self-contained.zip

Configuration commands

Simple Web App

This simple use case illustrates how to collect coverage with the CD agent from a web application started without parameters.

.\net6.0\SL.DotNet.exe cdAgent --appName "TestApp" --branchName "main" --buildName "$(Get-Date -Format "yyyy-MM-dd-HH-mm-ss")" --labId "integ_main_integration_TestApp_Integration" \
    --binDir "WeatherApi\bin\Debug\net6.0" --includeNamespace "WeatherApi*" \
    --target "WeatherApi\bin\Debug\net6.0\WeatherApi.exe" --workingDir "WeatherApi\bin\Debug\net6.0"  \
    --identifyMethodsByFqn
