Docker setup doesn't work and gives all Cachet config pages in one page

[AIndoria]

Essentially, this, I have gotten this after multiple reinstalls:

Here's my docker-compose file:

version: "3"
 
services:
  postgres:
    image: postgres:12-alpine
    volumes:
      - /var/lib/postgresql/data
    environment:
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=833d4aa3d852c583
    restart: always
  cachet:
    image: cachethq/docker:latest
    ports:
      - 8787:8000
    links:
      - postgres:postgres
    environment:
      - DB_DRIVER=pgsql
      - DB_HOST=postgres
      - DB_PORT=5432
      - DB_DATABASE=postgres
      - DB_USERNAME=postgres
      - DB_PASSWORD=833d4aa3d852c583
      - DB_PREFIX=chq_
      - APP_KEY=base64:UWLlBazkwP3z9G7a4Qb/Xkx4Q3FNSVhv0ClqBppPggo=
      - APP_LOG=errorlog
      - APP_ENV=${APP_ENV:-production}
      - APP_DEBUG=false
      - DEBUG=false
    depends_on:
      - postgres
    restart: on-failure

most likely cachet js and css are still served to the localhost:8000 , but your entry point is 8787 . can you map it to 8000?
(or having nginx in front with something like this)

server {
  listen 80;
  # the servername
  server_name _;
  location / {
    proxy_pass http://localhost:8000/;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
  }
}

Hm, what happens if I already have services being served on :8000?
