Here is the output from Docker-Compose Run Command in Pipeline. I don't know how to get the key from Application Insight resource in my subscription key is there but I don't know how to supply that key to pipeline at run time or substitute.

    Hi @Zafar Ahmed ,

    Welcome to Microsoft Q&A! Thanks for posting the question.

    Based on my understanding, you are trying to set the InstrumentationKey in the following method using the TelemetryConfiguration.InstrumentationKey property. Ref: TelemetryConfiguration.InstrumentationKey Property 

    LoneWolf.API.AccountsPayable.Program.<>c.<CreateHostBuilder>b_1_0(HostBuilderContext hostingContext, LoggerConfiguration loggerConfiguration) in /src/LoneWolf.API.AccountsPayable/Program.cs:line 42

    I would suggest using environment variable feature of dockerfile/docker compose to pass on the instrumentation key as environment variable in your PipeLine. More details are available here: Environment variable in Compose. This environment variable can then be read in your method and then assigned to the InstrumentationKey property.

    Please let me know if you have any questions.
