So I have two different applications one wordpress and other is api. And both running on docker containers and have their own configurations. This is their docker-compose settings:
version: "3.8"
services:
app:
container_name: ${APP_NAME}_app
build:
context: .
dockerfile: ./.docker/php/Dockerfile
expose:
- 9000
volumes:
- .:/usr/src/app
- ./public:/usr/src/app/public
depends_on:
- db
networks:
- app_network
nginx:
container_name: ${APP_NAME}_nginx
build:
context: .
dockerfile: ./.docker/nginx/Dockerfile
volumes:
- ./public:/usr/src/app/public
ports:
- "8081:8081"
expose:
- 8081
environment:
NGINX_FPM_HOST: app
NGINX_ROOT: /usr/src/app/public
depends_on:
- app
networks:
- app_network
db:
container_name: ${APP_NAME}_db
image: mysql:5.7
volumes:
- db_data:/var/lib/mysql
ports:
- "3307:3306"
environment:
MYSQL_ROOT_PASSWORD: ${DB_PASSWORD}
MYSQL_PASSWORD: ${DB_PASSWORD}
MYSQL_DATABASE: ${DB_DATABASE}
MYSQL_ALLOW_EMPTY_PASSWORD: "yes"
networks:
- app_network
networks:
app_network:
driver: bridge
volumes:
db_data:
driver: local
And this is my wordpress configuration:
version: '3.8'
services:
mysql:
image: mysql:5.7
environment:
- MYSQL_ROOT_PASSWORD=somewordpress
- MYSQL_DATABASE=wordpress
- MYSQL_USER=wordpress
- MYSQL_PASSWORD=wordpress
expose:

healthcheck:
test: mysqladmin ping -h 127.0.0.1 -u $$MYSQL_USER --password=$$MYSQL_PASSWORD

timeout: 3s
retries: 30
networks:
- app_network
wordpress:
build:
context: .
dockerfile: Dockerfile
depends_on:
mysql:
condition: service_healthy
volumes:
- .:/var/www/html/wp-content/plugins/name
ports:
- "80:80"
restart: always
environment:
- WORDPRESS_URL=http://localhost
- WORDPRESS_DB_HOST=mysql
- WORDPRESS_DB_USER=wordpress
- WORDPRESS_DB_PASSWORD=wordpress
- WORDPRESS_DB_NAME=wordpress
networks:
- app_network
networks:
app_network:
driver: bridge
And when I try to make request to api to this URL http://localhost:8081 well nothing happens. Locally works everything fine but on docker it doesn't.
Would appreciate some help how to make this work :)
If you have a docker container and you do http://localhost:8081, you wont go to your host pc, but to the container itself.
In docker-compose you need to replace localhost with the service name:
For example if you want to access 8081 of the nginx, you need to connect to http://nginx:8081

I'm having a problem persisting data with docker-compose.
I want my service chatmysql to persist data I put inside a database, but everytime i run docker-compose down it all vanishes.
I checked directory /var/lib/docker/volumes to see if it stores data there when containers are running and the volume was completely empty.
I didn't have that issue when I was running containers with docker run command so I guess its fault of my docker-compose.yaml file. Can someone help me?
I'm running this on Ubuntu 20.04.
version: '3'

You need to change the mounted volume, try this :
version: '3.7'
services:

image: mysql/mysql-server
container_name: chatmysql
hostname: db

Context
Our solution send emailing campaign, and some email provider makes temporary blacklist because we used inexistant email addresses (they may be created/imported by any user)
Solution
I try to implement a email checker based on https://www.codexworld.com/verify-email-address-check-if-real-exists-domain-php/
Problem
From my local computer, this script works (when my IP is not temporary blacklisted) but from my Docker Container stream_socket_client or even telnet always times out.
As I see, MX servers always time out non verified requester but how can I make it work from my docker container?
I've no specific docker configuration for the port 25.
Thank you

I have a container with RabbitMQ, it has to connect to the external IP of the application container, the problem is that this external IP is dynamic and changes every time. Accordingly, I have to manually change the configuration of my RabbitMQ every time. Maybe you can somehow set a static ip for the "App" container so that it does not change or somehow connect these two containers?

If they are in the same networks You can simply use the service name instead of the IP, just use the app, You can ping the app service name inside the rabbitMQ container and it works.
as you are using docker-compose all your containers are already on the same network. You can access a container from another container using the name you have specified:
i.e for rabbitmq it is rabbit
for redis it will be redis

I have four services. Three of them work fine and no problem at all, but phpmyadmin doesn't work at all. The thing is all is work fine, database, webserver, but not phpMyAdmin. When I try to go to localhost:8080, it says site can't be reached. I don't know what's going on. What am I missing?
I have one docker-compose file that have nginx, mysql and phpmyadmin.
phpmyadmin is open in port 8080 in this address mydomain.com:8080 as well.
How can I convert this address to http://phpmyadmin.mydomain.com or http://pma.mydomain.com in my server?

I don't know how to configure nginx file to achieve this goal.
You can use the repo -> https://github.com/jwilder/nginx-proxy
This is what I'm using to create new local domain name for each project.
You have to add "VIRTUAL_HOST" to the environment, expose the ports ("expose: 80") and also add the new domain in your /etc/hosts.
