Deploying doccano under prefix

[singles]

Is there an instruction how to run doccano under prefix? So no doccano.example.com and apps.example.com/doccanoinstead.

After some digging into codebase I've managed to run frontend under prefix by using router setting in nuxt.config.js:

 router: {
    base: '/doccano/'
  },

Unfortunately, login doesn't work as it still sends request to /v1/auth/login.

I also tried changing PUBLIC_PATH, but due then files are put in different subdirectory inside frontent/client/dist which requires adapting Dockerfile.

I have I feeling that there's an easier way to achieve what I'm trying to achieve and I'm just doing something wrong 🤔

EDIT:

I went a little bit further with these nuxt.config.js settings:

export default {
  router: {
    base: '/doccano/'
  },
  // other settings
  env: {
    baseUrl: '/doccano/v1' 
  },
}

Frontend renders correctly, favicon still doesn't work, but that's a minor stuff. What doesn't work is Django admin, also import seems to call a path without /doccano prefix.

PS. I think it would be useful to add such instructions to README :)
