I executed docker-compose up and my services worked as well but unfortunately when i hit the url " http://localhost:3000 " it gives me an error I'll paste the docker-compose.yml here.
version: "3.7"
services:
db:
image: postgres
container_name: psql
environment:
POSTGRES_DB: ${DB_DATABASE}
POSTGRES_USER: ${DB_USERNAME}
POSTGRES_PASSWORD: ${DB_PASSWORD}
volumes:
- postgres:/var/lib/postgresql/data
- ./postgresql/conf:/etc/postgresql/
restart: always
ports:
- '5432:5432'
api:
build: .
container_name: api
restart: always
command: yarn start
depends_on:
- db
ports:
- "3000:3000"
volumes:
- .:/usr/app
volumes:
postgres:
When I get into the container and execute curl localhost:3000 it works fine.
My problem was solved after I changed the host in my node api to '0.0.0.0' it was 'localhost' so I think the application was running only inside the container and after that change it was visible from all the created network.

I am using the following docker configuration:
version: "3"
services:
database:
image: mysql
ports:
- "3306:3306"
environment:
MYSQL_ROOT_PASSWORD: 1009
restart: "always"
phpmyadmin:
image: phpmyadmin
ports:
- "8080:80"
environment:
PMA_HOST: database
restart: "always"
depends_on:
- database
It works, but if I change the mysql port for my PC to - "3360:3306" (for example 3306 may be busy with the main mysql service running on the computer) - it stops working. If I do this, I will be able to connect to mysql from my computer in CMD like mysql -u root -P 3360 -p, but phpmyadmin will give the error - connection refused.
No matter what I do, I see this error. For example I used the following docker configuration:
version: "3"
services:
database:
image: mysql
networks:
- my-network
ports:
- "3360:3306"
environment:
MYSQL_ROOT_PASSWORD: 1009
restart: "always"
phpmyadmin:
image: phpmyadmin
links:
- database
networks:
- my-network
ports:
- "8080:80"
environment:
PMA_HOST: database
PMA_PORT: 3360
restart: "always"
depends_on:
- database
networks:
my-network:
Even all of this didn't work. Phpmyadmin gave out one inscription when trying to connect - Connection refused all the time. But it still worked in the terminal.
Why can't I use a different port for phpmyadmin in docker?
I have this docker-compose file where I have a couple of services:

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:

So I am creating an application that is running in a docker container on port 3000 of my local machine. I can open the app at localhost:3000, I can also open it on another device but on the same network by using 192.168.68.100:3000. However, I can't access the app by visiting my_public_ip:3000. I added port forwarding on my router for port 3000. I am running the app using docker-compose up and this is my docker-compose file:
version: '3.7'
services:
main:
container_name: main
build:
context: .
target: development
volumes:
- .:/usr/src/app
- /usr/src/app/node_modules
ports:
- 3000:3000
command: npm run start:dev
env_file:
- .env
networks:
- webnet
depends_on:
- db
db:
container_name: db
image: mysql
command: --default-authentication-plugin=mysql_native_password
restart: always
environment:
MYSQL_DATABASE: "..."
MYSQL_USER: "..."
MYSQL_PASSWORD: "..."
MYSQL_ROOT_PASSWORD: "..."
adminer:
container_name: adminer
image: adminer
restart: always

Any suggestions what am I missing?
