Im trying to deploy with docker compose an app; mi yml is:
version: '3.9'
services:
db:
image: mongo
restart: always
volumes:
- 'dbdata:/data/db'
container_name: database
server:
build: .
restart: always
ports:
- '2000:2000'
depends_on:
- db
container_name: api
links:

frontend:
build: ./client
restart: always
ports:
- '3000:3000'
depends_on:
- server
container_name: client

When i docker compose up -d this in my PC it works correctly, but when i do the same thing in a oracle linux 8.6 fedora; seems like is working fine until came to the lines:
Network soccer_default Created
no such service: database
And stop the process. Is something related with the machine or docker version?

I have this docker-compose file where I have a couple of services:
version: "3.8"
services:
app:
container_name: mobile_app_api
env_file:
- .env.development
command: npm run watch:dev
build:
context: .
target: development
dockerfile: ./Dockerfile
restart: always
volumes:
- /usr/src/app/node_modules
- ./:/usr/src/app
depends_on:
- postgres
- redis
extra_hosts:
- host-machine:host-gateway
network_mode: host
redis:
image: "redis:alpine"
container_name: mobile_app_cache
postgres:
image: postgres
container_name: mobile_app_database
restart: "unless-stopped"
environment:
TZ: 'GMT'
PGTZ: 'GMT'
POSTGRES_USER: postgres
POSTGRES_PASSWORD: postgres
POSTGRES_DB: mobile_app_database
volumes:
- /:/data/postgres
network_mode: host
Api is supposed to work on localhost:3333, but when I start this with docker-compose up --build in terminal I get this:
mobile_app_api | server running on http://[::1]:3333
And here is 2 things.
Why does it work on IPv6?
How can I change host and make it work on localhost?
PS. My computer is MacOS, but in settings I have turned off IPv6.
I was trying to use host.docker.internal (and gateway.docker.internal) in my compose file, but it didn't work:
extra_hosts:
- host.docker.internal:host-gateway
I am beginner in Docker and can not get response from my project that running in docker. I have a Go project with 4 services.

I am developing a workflow service as a training project. Abstracting from the details, everything you need to know for this question is in the image. For deployment, I rented a server and ran docker-compose on it. Everything works well, but what I'm worried about is that ports 8000 and 5432 are open.
The first question is, is it worth worrying? And if so, how to get rid of it?
Docker-compose file content below
version: "3"
services:
db:
container_name: 'emkk-db'
image: postgres
volumes:
- ./backend/data:/var/lib/postgresql/data
env_file:
- ./backend/db.env
ports:
- "5432:5432"
backend:
container_name: 'emkk-backend'
image: emkk_backend
build: ./backend
volumes:
- ./backend:/emkk/backend
env_file:
- ./backend/.env
ports:
- "8000:8000"
depends_on:
- db
frontend:
container_name: 'emkk-frontend'
image: emkk_frontend
build: ./frontend
command: npm run start
env_file:
- ./frontend/.env
volumes:
- /emkk/frontend/node_modules
- ./frontend:/emkk/frontend
ports:
- "80:80"
depends_on:

I also want to configure HTTPS protocol. I tried installing nginx and putting a certificate on it using a certbot, and then proxying requests to containers. I sat with this for several hours and I still did not manage to achieve anything better than a HTTPS for the nginx start page.
Maybe I'm doing completely wrong things, but I'm new to this, I haven't had to deal with deployments before. I would be grateful for your answers, which will contain an idea or an example of how you can do this.
If you don't have a connection to 8000 (probably WAS) or 5432 (database) from an external server, you can change docker-compose.yml to:
you have to expose only necessary ports for external clients.
when you connect to backend from web, you should use service name like backend:8000
when you connect to db from backend, you should use service name like db:5432
version: "3"
services:
db:
container_name: 'emkk-db'
image: postgres
volumes:
- ./backend/data:/var/lib/postgresql/data
env_file:
- ./backend/db.env
backend:
container_name: 'emkk-backend'
image: emkk_backend
build: ./backend
volumes:
- ./backend:/emkk/backend
env_file:
- ./backend/.env
depends_on:
- db
frontend:
container_name: 'emkk-frontend'
image: emkk_frontend
build: ./frontend
command: npm run start
env_file:
- ./frontend/.env
volumes:
- /emkk/frontend/node_modules
- ./frontend:/emkk/frontend
ports:
- "80:80"
depends_on:
- backend
And, you can use nginx proxy manager to service with HTTPS and a certificate from the certbot.
I am currently working on a mobile app that connects to a server instance in docker through a docker-compse instance that can be see by an emulator on my developemnt machine fine, but if I try and use my mobile I can't see the server as it is not on the same network. is there easy way I can set this up to so it can be seen by both my emulator and my mobile at the same time.
