This repository allows you to quickly install the Varnish reverse proxy into a DDEV project using just ddev get ddev/ddev-varnish.
ddev get ddev/ddev-varnishddev restart
The Varnish service inserts itself between ddev-router and the web container, so that calls
to the web container are routed through Varnish first. The docker-compose.varnish.yaml
installs Varnish and uses the default domain as its own host name. A docker-compose.varnish-extras.yaml file is generated on install which replaces the VIRTUAL_HOST variable of the web container with a sub-domain of the website URL. For example, mysite.ddev.site, would be accessible via Varnish on mysite.ddev.site and directly on novarnish.mysite.ddev.site.
If you use a project_tld other than ddev.site or additional_fqdns DDEV will help add hosts entries for the hostnames automagically; however, you'll need to add entries for the novarnish.* sub-domains yourself, e.g. ddev hostname novarnish.testaddfqdn.random.tld 127.0.0.1.
Run ddev get ddev/ddev-varnish after changes to name, additional_hostnames, additional_fqdns, or project_tld in .ddev/config.yml so that .ddev/docker-compose.varnish-extras.yaml is regenerated.
This addon also providers several helper commands. These helpers allow developers to run Varnish commands from the host, however, the commands are actually run inside the Varnish container.
