List of environment variables for containers

frappe-worker and erpnext-worker

Following environment variables are set into sites volume as common_site_config.json. It means once the file is created in volume, the variables won't have any effect, you need to edit the common_site_config.json to update the configuration

• DB_HOST: MariaDB host, domain name or ip address.
• DB_PORT: MariaDB port.
• REDIS_CACHE: Redis cache host, domain name or ip address.
• REDIS_QUEUE: Redis queue host, domain name or ip address.
• REDIS_SOCKETIO: Redis queue host, domain name or ip address.
• SOCKETIO_PORT: : Port on which the SocketIO should start.
• WORKER_CLASS: Optionally set gunicorn worker-class. Supports gevent only, defaults to gthread.

frappe-nginx and erpnext-nginx

These variables are set on every container start. Change in these variables will reflect on every container start.

• FRAPPE_PY: Gunicorn host to reverse proxy. Default: 0.0.0.0
• FRAPPE_PY_PORT: Gunicorn port to reverse proxy. Default: 8000
• FRAPPE_SOCKETIO: SocketIO host to reverse proxy. Default: 0.0.0.0
• SOCKETIO_PORT: SocketIO port to reverse proxy. Default: 9000
• HTTP_TIMEOUT: Nginx http timeout. Default: 120
• UPSTREAM_REAL_IP_ADDRESS : The trusted address (or ip range) of upstream proxy servers. If set, this will tell nginx to trust the X-Forwarded-For header from these proxy servers in determining the real IP address of connecting clients. Default: 127.0.0.1
• UPSTREAM_REAL_IP_RECURSIVE: When set to on, this will tell nginx to not just look to the last upstream proxy server in determining the real IP address. Default: off
• UPSTREAM_REAL_IP_HEADER: Set this to the header name sent by your upstream proxy server to indicate the real IP of connecting clients. Default: X-Forwarded-For
• FRAPPE_SITE_NAME_HEADER: NGINX X-Frappe-Site-Name header in the HTTP request which matches a site name. Default: $host
• HTTP_HOST: NGINX Host header in the HTTP request which matches a site name. Default: $http_host
• SKIP_NGINX_TEMPLATE_GENERATION: When set to 1, this will not generate a default NGINX configuration. The config file must be mounted inside the container (/etc/nginx/conf.d) by the user in this case. Default: 0

frappe-socketio

This container takes configuration from common_site_config.json which is already created by erpnext gunicorn container. It doesn't use any environment variables.
