Introduction

Because Varnish doesn't support SSL, most people choose a setup where Nginx SSL will forward all traffic to Varnish and Varnish will forward will forward the traffic it cannot handle back to nginx. Or worse, bind Varnish on port 80 and direct all traffic into Varnish. This will already degrade performance, because Varnish will purge more because static files are also taking up room in the cache.

Default configuration

Next up, the Nginx configuration of Magento will handle static files.

Docker issues are frequently logged for DNS resolution in containers because it doens't inhert or get values for DNS from NetworkManager which leverages a built in dnsmasq to inteligently manage DNS.
