Environment Variables

All of the commands are directly passed to container as per type of service. Only environment variables used in image are for nginx-entrypoint.sh command. They are as follows:

• BACKEND: Set to {host}:{port}, defaults to 0.0.0.0:8000
• SOCKETIO: Set to {host}:{port}, defaults to 0.0.0.0:9000
• UPSTREAM_REAL_IP_ADDRESS: Set Nginx config for ngx_http_realip_module#set_real_ip_from, defaults to 127.0.0.1
• UPSTREAM_REAL_IP_HEADER: Set Nginx config for ngx_http_realip_module#real_ip_header, defaults to X-Forwarded-For
• UPSTREAM_REAL_IP_RECURSIVE: Set Nginx config for ngx_http_realip_module#real_ip_recursive Set defaults to off
• FRAPPE_SITE_NAME_HEADER: Set proxy header X-Frappe-Site-Name and serve site named in the header, defaults to $host, i.e. find site name from host header. More details below
• PROXY_READ_TIMEOUT: Upstream gunicorn service timeout, defaults to 120
• CLIENT_MAX_BODY_SIZE: Max body size for uploads, defaults to 50m

To bypass nginx-entrypoint.sh, mount desired /etc/nginx/conf.d/default.conf and run nginx -g 'daemon off;' as container command.

Configuration

We use environment variables to configure our setup. docker-compose uses variables from the environment: section of the services defined within and the.env file, if present. Variables defined in the .env file are referenced via ${VARIABLE_NAME} within the docker-compose .yml file. example.env contains a non-exhaustive list of possible configuration variables. To get started, copy example.env to .env.

FRAPPE_VERSION

Frappe framework release. You can find all releases here.

DB_PASSWORD

Password for MariaDB (or Postgres) database.

DB_HOST

Hostname for MariaDB (or Postgres) database. Set only if external service for database is used or the container can not be reached by its service name (db) by other containers.

DB_PORT

Port for MariaDB (3306) or Postgres (5432) database. Set only if external service for database is used.

REDIS_CACHE

Hostname for redis server to store cache. Set only if external service for redis is used or the container can not be reached by its service name (redis-cache) by other containers.

REDIS_QUEUE

Hostname for redis server to store queue data and socketio. Set only if external service for redis is used or the container can not be reached by its service name (redis-queue) by other containers.

ERPNEXT_VERSION

ERPNext release. This variable is required if you use ERPNext override.

LETSENCRYPT_EMAIL

Email that used to register https certificate. This one is required only if you use HTTPS override.

FRAPPE_SITE_NAME_HEADER

This environment variable is not required. Default value is $$host which resolves site by host. For example, if your host is example.com, site's name should be example.com, or if host is 127.0.0.1 (local debugging), it should be 127.0.0.1 This variable allows to override described behavior. Let's say you create site named mysite and do want to access it by 127.0.0.1 host. Than you would set this variable to mysite.

There is other variables not mentioned here. They're somewhat internal and you don't have to worry about them except you want to change main compose file.
