Latex development container for VS-Code Desktop/Code-Server in Coder

Help needed!
This devcontainer is not production ready!

Code-server latest does not currently work with the Google Chrome browser. Please use firefox.

Please read first my Coder installation guide in this repository.

1. Login in coder
2. Use the template Docker (Devcontainer)
3. Clone this repo https://github.com/joergklein/devcontainer-latex.git

Help needed

1. Visit https://github.com/joergklein/devcontainer-latex
2. Please take a look at the Dockerfile and docker-compose.yaml. Are they correct?
3. In the devcontainer.yaml I want to install the extensions and settings per default. Unfortunately, the extensions and settings are not installed in the code server. What is wrong?
4. Compile some of your LaTeX code. Tables, pictures etc.
5. What can be improved in the configuration?
