Nice! The only difference is that we dont have a custom 404 page.

[unclekingpin]

actually we need the 404 handler for sure, which we will customize later

[edde746]

The current dockerfile does not have a custom 404 page either, it just has a comment saying it should be added later. To add a custom 404 page, a 404.html would need to be created and passed as the fallback argument to goStatic.

Have you considered using caddy instead?
That way you can make it super super simple for people to also auto gen tls etc?
https://caddyserver.com/

Also has a 17mb base image size for caddy

TLS should be handled by the user IMO, gives them control of how they want to do it. The purpose of the Docker image should just be to serve the static files and nothing more.

As for the size, while ~16 MB difference does not matter, the base size of pierrezemb/gostatic is only ~2 MB. 18 MB is for goStatic + the static files.

While I agree with the statement TLS should be handled by the user, I have to add it still would be. They'd still have to mount a caddy file to enable it, configure their load balancing, cache settings, rewrites etc if they wanted to opt into the features. The point is they'd have the option to.

Just gives users who are hosting in something like azure container apps / instances, where they probably wouldn't want to pay for azure gateway or introduce a second container instance as a load balancer the ability to have easily opt-in features, with the use of a single file server rather than a static file server reverse proxied by a second file server.

That's ok I did say "considered" 😛
