Name

lua-resty-github - Lua library for using the github api

Table of Contents

Status

This library is still under early development and considered experimental.

Description

This Lua library is a github utility for the ngx_lua nginx module.

One potential use case for this is automatically filing issues for you when errors occur in your code base.

Synopsis

    lua_package_path "/path/to/lua-resty-github/lib/?.lua;;";
    
    server {
        location /test {
            content_by_lua '
                local github = require "resty.github"
                
                local gh, err = github:new("github_token")
                
                local issue_url, err = gh:safe_create_issue("github_owner", "github_repo", "issue_title", "issue_body")
                
                ngx.say("Issue created at: "..issue_url)
            ';
        }
        
        include .../lua-resty-github/conf/*.urls;
    }

Limitations

  • Only handles issues right now
  • Can't handle 2 factor auth

Installation

If you are using your own nginx + ngx_lua build, then you need to configure the lua_package_path directive to add the path of your lua-resty-github source tree to ngx_lua's LUA_PATH search path, and include the urls, as in

    # nginx.conf
    http {
    
        lua_package_path "/path/to/lua-resty-github/lib/?.lua;;";
        
        ...
        
        server {
        
            include .../lua-resty-github/conf/*.urls;
            
        }
    }

Ensure that the system account running your Nginx ''worker'' proceses have enough permission to read the .lua file.

Docker

I've also made a docker image to make setup of the nginx environment easier. View details here: https://registry.hub.docker.com/u/jamesmarlowe/lua-resty-github/

# install docker according to http://docs.docker.com/installation/

# pull image
sudo docker pull jamesmarlowe/lua-resty-github

# make sure it is there
sudo docker images

# run the image
sudo docker run -t -i jamesmarlowe/lua-resty-github
