Serve Varnish on port 80, use bundled config and forward Varnish requests to a webserver on
192.168.0.1 on port 8080 (which accepts HTTP and not HTTPS):
docker run -it -d --rm \
-e BACKEND_HOST=192.168.0.1 \
-e BACKEND_PORT=8080 \
-p "80:6081" \
devilbox/varnish:6Important:
When using a custom config, the BACKEND_HOST and BACKEND_PORT variables will have no effect
and you need to ensure to hard-code this in your custom config.

and forward Varnish requests to a webserver on 192.168.0.1 on port 8080 (which accepts HTTP and not HTTPS).
docker run -it -d --rm \ -e BACKEND_HOST=192.168.0.1 \ -e BACKEND_PORT=8080 \ -e VARNISH_CONFIG=/etc/varnish.d/my-varnish.vcl \ -v "/home/users/varnish/:/etc/varnish.d/" \ -p "80:6081" \ devilbox/varnish:6
