error with docker compose

[koebel]

When I build the app according to the instructions given in the README.md I get the following error message regarding the connectivity on endpoint of 3d_viewer. However the app seems to be running correctly in the browser.

Bind for 0.0.0.0:3000 failed: port is already allocated

The problem is this one. Could you find out what is running at port 3000?

[koebel]

sorry, ports were not listed in the code I copied above. but it's the app listed there. I didn't had anything else running on docker, only the app which was started using this command
docker run --rm -p3000:80 sawjan/web-app-3dmodel-viewer
which obviously does uses port 3000. Maybe I misunderstood the README... Is the docker container a precondition for building and running the app or an alternative?

[saw-jan]

Ah, now I see the problem.

docker run --rm -p3000:80 sawjan/web-app-3dmodel-viewer

This command is only meant to run when you are manually setting up the extension server and ocis separately.
If you are using docker compose setup then no need to start extension server separately using docker run ...

When setting locally for development, only follow this section https://github.com/saw-jan/web-app-3dmodel-viewer?tab=readme-ov-file#build-and-run. Then all should be fine

Docker Image is a separate topic

I've made some small changes in the documentation to make this clearer, see #14
