Single Compose Setup

This setup is a very simple single compose file that does everything to start required services and a frappe-bench. It is used to start play with docker instance with a site. The file is located in the root of repo and named pwd.yml.

Services

frappe-bench components

backend, serves gunicorn backend
frontend, serves static assets through nginx frontend reverse proxies websocket and gunicorn.
queue-long, long default and short rq worker.
queue-short, default and short rq worker.
schedule, event scheduler.
websocket, socketio websocket for realtime communication.

Run once configuration

configurator, configures common_site_config.json to set db and redis hosts.
create-site, creates one site to serve as default site for the frappe-bench.

Service dependencies

db, mariadb, container with frappe specific configuration.
redis-cache, redis for cache data.
redis-queue, redis for rq data and pub/sub.

Volumes

sites: Volume for bench data. Common config, all sites, all site configs and site files will be stored here.
logs: Volume for bench logs. all process logs are dumped here. No need to mount it. Each container will create a temporary volume for logs if not specified.

Adaptation

If you understand containers use the pwd.yml as a reference to build more complex setup like, single server example, Docker Swarm stack, Kubernetes Helm chart, etc.

This serves only site called frontend through the nginx. FRAPPE_SITE_NAME_HEADER is set to frontend and a default site called frontend is created.

Change the $$host will allow container to accept any host header and serve that site. To escape $ in compose yaml use it like $$. To unset default site remove currentsite.txt file from sites directory.
