Simple static http server

The aim of this project is to offer a simple http server with :

• just one feature : serve static files.
• simple to be configured : command line arguments.
• light : small binary size.
• very easy to deploy : copy the binary and that it ! No package, no node or python are required.

To realize this aim, the server is written in go with no additional modules.

Because of that, for example, under a Linux OS the required dependencies are only :

$ ldd simple-static-http-server 
	linux-vdso.so.1 (0x00007ffd3d8e6000)
	libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f1c79ab6000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f1c796c5000)
	/lib64/ld-linux-x86-64.so.2 (0x00007f1c79cd5000)

The size is also very small. For example, under Ubuntu 18.04 :

$ ll simple-static-http-server 
-rwxrwxr-x 1 ubuntu01 ubuntu01 6.5M Feb 12 13:53 simple-static-http-server

How to download the binary

Go to the releases page and download the last version version for your operating system.

How to build from sources

Prerequisites

• go binary (tested with go 1.11 et go 1.12).

Build

go build -o simple-static-http-server
go get github.com/stretchr/testify/assert
go test

Usage

All configurations are defined by command line arguments. These arguments is printed by the flag -h :

$ ./simple-static-http-server -h
Usage of ./simple-static-http-server:
  -d string
    	Directory which contains static files to be served (default "/home/ubuntu01/workspace-go/simple-static-http-server")
  -p int
    	Port (default 8080)

The default directory to be served is the current directory and the default is 8080.

To change it, use the flag -d and -p.

For example, to serve the directory /staic on port 9090.

$ ./simple-static-http-server -d /static -p 9090

In case of error, logs are printed.

$ ./simple-static-http-server -d /static -p 80  
2019/02/12 14:17:04 Cannot start the http server : listen tcp :80: bind: permission denied

In addition, the following exit codes are available.

• 1 : Error during get of current directory.
• 2 : Error during starting of the http server.

Deployment

Just copy the binary !

Docker

A docker image is available on dockerhub squareitservices/static-http-server.

The docker image is based on alpine with just the only one required dependecy libc6-compat.

Build image from dockefile

The dockerfile is a multi stage build which build the binary from sources and then create the docker image :

docker build -t static-http-server:tag .

The docker image is also light :

$ docker images | grep squareitservices/static-http-server
