Changes to Dockerfile(s) not considered during deployment

[kainawroth]

Hi everyone,

I forked the OTel Demo repo to experiment with different instrumentations and exporters, but I'm struggling with getting my modified version deployed.

Example
I made changes to the Ad Service Dockerfile to replace the OTel Java agent with the Application Insights version:

But when I use docker compose up it always shows the image ghcr.io/open-telemetry/demo:1.4.0-adservice in Docker, no matter if I run it with or without the --no-build flag, and it doesn't consider any of the modifications I made (both files are missing):

What am I doing wrong? Any help is appreciated!

Best Regards,
Kai

Hello Kai,

To build your own image, you can run:

docker compose build <SERVICE_NAME>

Or, if you want to build all of the services, you can run the same command without the service name.

The image will have the same name though. So you will still see ghcr.io/open-telemetry/demo as repository.

After built, you can use the:

docker compose up

To start the demo.
