Docker Compose Access Container From Another Machine

Question

I deployed Spring Boot application using Jenkins by docker-compose.yml. I can access the created container, but I cannot access the container from another machine on the same.network.

The command I used:

docker-compose run -d app 

docker-compose.yml

version: '3.1'
services:
  app:
    container_name: xxxxxx
    image: xxxxxx
    build: ./
    ports:
      - "8000:8000"
    restart: always
    environment:
      - POSTGRES_DB_HOST="xxxxxxxxx"
      - POSTGRES_PASSWORD="xxxxx"
      - POSTGRES_USER="postgres"
      - POSTGRES_DB="db_name"

How to solve the problem? Thanks in advance.

EDIT:

After Jenkins deployed the application successfully, I used docker inspect to check the container's IP and then I accessed on the host machine(Let's say the container has IP 1.2.3.4) with the following URL:

http://1.2.3.4:8000

I try to access another machine in the.network with the host machine by accessing URL like following(Let's say host machine has IP 2.3.4.5):

http://2.3.4.5:8000

But I could not see deployed web page like on the host machine, the error was like below:

This site can’t be reached
x.x.x.x refused to connect.

Your problem is the use of the docker-compose run command. From the documentation :

The second difference is that the docker-compose run command does not create any of the ports specified in the service configuration. This prevents port collisions with already-open ports.

Because you're using run , the port mapping between the host port 8000 and the container port 8000 isn't configured.

The normal way you bring up a docker-compose stack is through the use of the up command:

docker-compose up -d

You can specify a single service if you're trying to avoid bringing up all the services in your docker-compose.yaml file:

docker-compose up -d app
