    Article summary

    Follow the instructions here on how to add our profiler to your Dockerfile.

    Environment Variables

    Set the StackifyPrefix environment variable to 1 to set the profiler to Prefix mode.
    This will put Prefix compatible traces in /usr/local/prefix/log (Unices) or %ALLUSERSPROFILE%\Stackify\Agent\log (Windows).

    Binding the Host Trace directory to the Guest Trace directory

    To get Prefix to read the traces from your app in docker, you need to use bind-mounts as mentioned in this article.

    Example

    If the host OS is Windows and you have a Linux OS in the container, you need to bind %ALLUSERSPROFILE%\Stackify\Agent\log to /usr/local/prefix/log for Prefix to see the logs.

    Fixed Logging Directories for Java traces

    Linux: /usr/local/prefix/log

    Windows: %ALLUSERSPROFILE%\Stackify\Agent\log
    %ALLUSERSPROFILE is an environment variable. This is usually located at C:\ProgramData but may be on another drive.
    In Powershell, this would be $Env:ALLUSERSPROFILE.

    This will work on Docker Desktop because it detects Windows style paths.

    To bind these directories

    We use the --mount argument for the docker run command as follows:
    docker run -it --rm -p 8000:80 \ --mount type=bind,source="$Env:ALLUSERSPROFILE",target=/usr/local/prefix/log \ --name java_sample java-apm
