Docker

If your repository contains a Dockerfile, Webgune can use it to build the image. Pick the Dockerfile mode when creating the service or in its settings: the auto builder then steps aside and your Dockerfile takes precedence. In auto build, it is only used when no framework or language is recognized.

The port, once again

Whether in your Dockerfile's CMD or in your application code, the listening port must follow the PORT variable provided by Webgune:

CMD ["sh", "-c", "uvicorn main:app --host 0.0.0.0 --port $PORT"]

.dockerignore

Systematically exclude anything that bloats the build context without being useful to the final image:

node_modules
.git
.env
dist
*.log
