A really small, multi-arch, static web server for Docker

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.

Yeah, decided to drop support of unsecured HTTPS. Two-years ago, when I started GoStatic, there was no automatic HTTPS available. Nowadays, thanks to Let's Encrypt, it's really easy to do so. If you need HTTPS, I recommend caddy.

• A fully static web server embedded in a SCRATCH image
• No framework
• Web server built for Docker
• Light container
• More secure than official images (see below)
• Log enabled
• Specify custom response headers per path and filetype (info)

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

For me, the whole point of containers is to have a light container... Many links should provide you with additional 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

docker run -d -p 80:8043 -v path/to/website:/srv/http --name goStatic ghcr.io/tkw1536/ts:latest

./goStatic --help
Usage of ./goStatic:
  -append-header HeaderName:Value
        HTTP response header, specified as HeaderName:Value that should be added to all responses.
  -context string
        The 'context' path on which files are served, e.g. 'doc' will serve the files at 'http://localhost:<port>/doc/'
  -default-user-basic-auth string
        Define the user (default "gopher")
  -enable-basic-auth
        Enable basic auth. By default, password are randomly generated. Use --set-basic-auth to set it.
  -enable-health
        Enable health check endpoint. You can call /health to get a 200 response. Useful for Kubernetes, OpenFaas, etc.
  -enable-logging
        Enable log request
  -fallback string
        Default fallback file. Either absolute for a specific asset (/index.html), or relative to recursively resolve (index.html)
  -header-config-path string
        Path to the config file for custom response headers (default "/config/headerConfig.json")
  -https-promote
        All HTTP requests should be redirected to HTTPS
  -password-length int
        Size of the randomized password (default 16)
  -path string
        The path for the static files (default "/srv/http")
  -port int
        The listening port (default 8043)
  -set-basic-auth string
        Define the basic auth. Form must be user:password

The fallback option is principally useful for single-page applications (SPAs) where the browser may request a file, but where part of the path is in fact an internal route in the application, not a file on disk. goStatic supports two possible usages of this option:

1. Using an absolute path so that all not found requests resolve to the same file
2. Using a relative file, which searches up the tree for the specified file

The second case is useful if you have multiple SPAs within the one filesystem. e.g., / and /admin.
