Question

i have created one wordpress site using docker. to open it i need to open browser in got to localhost:8000. But if i want to make multiple wordpress sites how and where and what i need to configure to reach every each of them seperatly, becouse i cant get to them using only the same link. i am noob at docker.
i have created .yaml file from tutorial in youtube
version: '3'
# Database
services:
db:
image: mysql:5.7
platform: linux/amd64
volumes:

MYSQL_DATABASE: wordpress
MYSQL_USER: wordpress
MYSQL_PASSWORD: wordpress
networks:

# phpmyadmin
phpmyadmin:
depends_on:

# Wordpress
wordpress:
depends_on:

ports:
- '8000:80'
restart: always
volumes: ['./:/var/www/html']
environment:
WORDPRESS_DB_HOST: db:3306
WORDPRESS_DB_USER: wordpress
WORDPRESS_DB_PASSWORD: wordpress
networks:
- wpsite

wpsite:
volumes:
db_data:
and then i run the dockeer command
docker-compose up -d
which made all wordpress files
to open it i need to open link localhost:8000
how do i open another wordpress site? becouse i cant open them both with the same link.

If you want to be able to access multiple services then just assign them different ports.
In your example you configured wordpress to be exposed on port 8000 using:
ports:
- '8000:80'
So just assign to another wordpress instance(s) different port(s) (eg 8001, 8002, ...) using:
ports:
- '8001:80'
Example docker-compose.yaml
version: '3'
services:
db:
image: mysql:5.7
platform: linux/amd64
volumes:
- db_data:/var/lib/mysql
restart: always
environment:
MYSQL_ROOT_PASSWORD: password
MYSQL_DATABASE: wordpress-site1
MYSQL_USER: wordpress-site1
MYSQL_PASSWORD: wordpress-site1
networks:
- wpsite
phpmyadmin:
depends_on:
- db
image: phpmyadmin/phpmyadmin
restart: always
ports:
- '8080:80'
environment:
PMA_HOST: db
MYSQL_ROOT_PASSWORD: password
networks:
- wpsite
wordpress-site1: # Wordpress site 1
depends_on:
- db
image: wordpress:latest
ports:
- '8000:80' # This site will be accessible on localhost:8000
restart: always
volumes: ['./site-1:/var/www/html'] # Set different path on host
environment:
WORDPRESS_DB_HOST: db:3306
WORDPRESS_DB_NAME: wordpress-site1
WORDPRESS_DB_USER: wordpress-site1
WORDPRESS_DB_PASSWORD: wordpress-site1
networks:
- wpsite
wordpress-site2: # Wordpress site 2
depends_on:
- db
image: wordpress:latest
ports:
- '8001:80' # This site will be accessible on localhost:8001
restart: always
volumes: ['./site-2:/var/www/html'] # Set different path on host
environment:
WORDPRESS_DB_HOST: db:3306
WORDPRESS_DB_NAME: wordpress-site2
WORDPRESS_DB_USER: wordpress-site2
WORDPRESS_DB_PASSWORD: wordpress-site2
networks:
- wpsite
# Other wordpress instances
networks:
wpsite:
volumes:
db_data:
Don't forget that every wordpress service will need it's own database.
You can either define for each wordpress service it's own database service or use single (shared) DB service and create on it multiple databases (one for each wordpress service).
To do so first start up only db and phpmyadmin services using:
$ docker-compose up -d db phpmyadmin
Since PhpMyAdmin is set to be exposed on port 8080 go to http://localhost:8080, log in and create for each wordpress service it's own database and user.
Once done, update WORDPRESS_DB_* env variables (if needed) in docker-compose.yaml to match databases and user credentials you just created and if everything is ok start all wordpress services.
Based on example docker-compose.yaml you should be able to access:
wordpress-site1 on hppt://localhost:8000
wordpress-site2 on hppt://localhost:8001
