Problem: Connecting PHP-FPM and Nginx Docker Containers
Linking PHP-FPM and Nginx Docker containers can be difficult. This setup is needed for running PHP applications in a containerized environment, but it requires correct configuration for good communication between the two services.
Configuring Nginx and PHP-FPM Containers
Docker Compose Configuration
To connect Nginx and PHP-FPM containers, update your docker-compose.yml file:
nginx:
build: .
ports:
- "80:80"
volumes:
- ./:/complex/path/to/files/
links:
- fpm
fpm:
image: php:fpm
ports:
- ":9000"
volumes:
- ./:/complex/path/to/files/This configuration links the Nginx and PHP-FPM containers and sets up volume mounts for shared files.
Tip: Environment Variables for Flexibility
Use environment variables in your docker-compose.yml file to make your configuration more flexible and easier to manage across different environments:
nginx:
build: .
ports:
- "${NGINX_PORT:-80}:80"
volumes:
- ${APP_PATH:-./}:/complex/path/to/files/
links:
- fpm
fpm:
image: php:fpm
ports:
- "${PHP_FPM_PORT:-9000}"
volumes:
- ${APP_PATH:-./}:/complex/path/to/files/This allows you to easily change ports and file paths by setting environment variables or using a .env file.
Nginx Configuration
Update your Nginx virtual host configuration (default.conf) as follows:
server {
listen 80;
root /complex/path/to/files;
location / {
try_files $uri /index.php$is_args$args;
}
location ~ ^/.+\.php(/|$) {
fastcgi_pass fpm:9000;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}This configuration updates the fastcgi_pass directive to use the container name 'fpm' and port 9000. It also sets the correct root path for handling PHP scripts.
PHP-FPM Container Setup
The PHP-FPM container listens on port 9000 by default. Make sure the file paths in the PHP-FPM container match those in the Nginx container. Both containers should have access to the files at '/complex/path/to/files/'.
By aligning the file paths and configurations between Nginx and PHP-FPM containers, you allow proper communication and execution of PHP scripts.
