goStatic

A really small static web server for Docker

The goal

My goal is to create to smallest docker container for my web static files. The advantage of Go is that you can generate a fully static binary, so that you don't need anything else.

Features

• A fully static web server in 5MB
• Web server build for Docker
• HTTPS by default
• Can generate certificate on his onw
• Light container
• More security than official images (see below)
• Log enabled

Why?

Because the official Golang image is wayyyy to big (around 1/2Gb as you can see below) and could be unsecure.

For me, the whole point of containers is to have a light container... Many links should provide you with additionnal info to see my point of view:

• Over 30% of Official Images in Docker Hub Contain High Priority Security Vulnerabilities
• Create The Smallest Possible Docker Container
• Building Docker Images for Static Go Binaries
• Small Docker Images For Go Apps

How to use

// HTTPS server
docker run -d -p 443:8043 -v path/to/website:/srv/http --name goStatic pierrezemb/gostatic
// HTTP server
docker run -d -p 80:8043 -v path/to/website:/srv/http --name goStatic pierrezemb/gostatic --forceHTTP

Wow, such container! What are you using?

I'm using echo as a micro web framework because he has great performance, and golang-builder to generate the static binary (command line in the makefile)

I'm also using the centurylink/ca-certs image instead of the scratch image to avoid this error:

x509: failed to load system roots and no roots provided

The centurylink/ca-certs image is simply the scratch image with the most common root CA certificates pre-installed. The resulting image is only 258 kB which is still a good starting point for creating your own minimal images.
