Varnish
The Lagoon Varnish image Dockerfile. Based on the official varnish package provided by alpine:3.7 image.
By default, vmod-dynamic and vmod-bodyaccess modules are installed.

Lagoon adaptions

This image is prepared to be used on Lagoon. There are therefore some things already done:
    Folder permissions are automatically adapted with fix-permissions, so this image will work with a random user.

Included varnish modules

    vbox-dynamic - Dynamic backends from DNS lookups and service discovery from SRV records.
    vbox-bodyaccess - Varnish vmod that lets you access the request body.
