I've created docker-compose.yml file with the following content. My docker service runs ok, docker run hello-world works just fine and after running command
docker-compose build && docker-compose up -d
I see no errors but in the browser I'm getting an error Unable to connect when I go to localhost:8000

When I run command

I can see the list of files and folders

The services are named equally because those are two equal projects...
When I do:
docker-compose -f infra/local/docker-compose.yml ps
It would show me containers from the other project:
jorgee#jorgee:~/Desktop/Proyectos/sss/sss_api_mx$ docker-compose -f ./infra/local/docker-compose.yml ps

Why docker-compose gets confused and shows me data from another project?
I was trying to create a PHP development environment with PHP, MariaDB, and a tutorial suggested to use Adminer for database management. So I generate my docker-compose.yml file like this:
version : '3.1'
services:
php:
build:
context: .
dockerfile: Dockerfile
ports:
- 80:80
volumes:
- ./src:/var/www/html/
db:
image: mariadb
restart: always
environment:
MYSQL_ROOT_PASSWORD: example
volumes:
- ./mariadb-data:/var/lib/mysql
adminer:
image: adminer
environment:
ADMINER_DEFAULT_SERVER: db
restart: always
ports:
- 8080:8080
But when I set the volumes for MariaDB, I got an error in the Adminer login page. When I don't set them it seems to work well.
version : '3.1'
services:
php:
build:
context: .
dockerfile: Dockerfile
ports:
- 80:80
volumes:
- ./src:/var/www/html/
db:
image: mariadb
restart: always
environment:
MYSQL_ROOT_PASSWORD: example
volumes:
- ./mariadb-data:/var/lib/mysql
adminer:
image: adminer
environment:
ADMINER_DEFAULT_SERVER: db
restart: always
ports:

- db
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

and then
docker-compose ps
to see my container and i always get the composer contaier down with code 0. that's the screenshot
:
can someone explain me why i can't put this container up. Thanks a lot
composer isn't a program that stays alive. It's a program that does specific some work and then exits.
There's not much purpose in keeping it "up", since it's not going to do anything like the other processes do (nginx intercepts web traffic and writes response, mysql accepts database connections and reads/writes from a database, php serves web content, redis can be connected to as a cache).
I have two project using docker, in first project is laravel, and second is wordpress. In laravel I want to connect both database (to convert laravel database to wordpress database).
but I don't know how to connect it:
here is two docker-compose.yml file:
in laravel:
version: '2'
services:
# The Application
app:
build:
context: ./
dockerfile: app.dockerfile
working_dir: /var/www
volumes:
- ./:/var/www
environment:
- "DB_PORT=3306"
- "DB_HOST=database"
# The Web Server
web:
build:
context: ./
dockerfile: web.dockerfile
working_dir: /var/www
volumes_from:
- app
ports:
- 8081:80
# The Database
database:
image: mysql:5.6
volumes:
- dbdata:/var/lib/mysql
environment:
- "MYSQL_DATABASE=homestead"
- "MYSQL_USER=homestead"
- "MYSQL_PASSWORD=secret"
- "MYSQL_ROOT_PASSWORD=secret"
ports:
- "33061:3306"
volumes:
dbdata:
and my docker-compose.yml file in wordpress:
version: '2'
services:
db:
image: mysql:5.7
volumes:
- db_data:/var/lib/mysql
restart: always
environment:
MYSQL_ROOT_PASSWORD: 123456
MYSQL_DATABASE: wpshop
MYSQL_USER: root
MYSQL_PASSWORD: 123456
wordpress:
depends_on:
- db
image: wordpress:latest
volumes:
- ./:/var/www/html
ports:
- "8080:80"
restart: always
environment:
WORDPRESS_DB_HOST: db:3306
WORDPRESS_DB_USER: root
WORDPRESS_DB_PASSWORD: 123456
volumes:
db_data:
I cd to each project and run docker-compose up -d
Please help me!
Create an external network and use that network as default network for all your containers. This way you'll be able to reach all container by its name.
Take a look to Docker container networking: https://docs.docker.com/engine/userguide/networking/
