How to activate and setup full page caching using Varnish from command line

Question

Is there a way to activate the Varnish use using the command line, not the admin interface? In the bin/magento comand line tool there are options for cache but nothing specific for Varnish.

I am building an Ansible script that automatizes the installation and configuration of the M2EE and this step seems that has to be done manually (which I did and works well). I would prefer a command line action than changed direct values in the mySql, but maybe you have other suggestions.

Answer 1

Use:

php bin/magento config:set system/full_page_cache/caching_application 2

And follow the same patterns for the other paths, like so:

php bin/magento config:set system/full_page_cache/varnish/access_list localhost
php bin/magento config:set system/full_page_cache/varnish/backend_host localhost
php bin/magento config:set system/full_page_cache/varnish/backend_port 8080

Answer 2

How about adding mysql script.sql with the following contents:

insert into core_config_data(scope,scope_id,path,value) values ('default',0,'system/full_page_cache/caching_application',2), ('default',0,'system/full_page_cache/varnish/access_list','localhost'), ('default',0,'system/full_page_cache/varnish/backend_host','localhost'),('default',0,'system/full_page_cache/varnish/backend_port','8080');

You can change localhost and 8080 to your varnish settings.
