Unable to start container.

[Trouble123]

Hi

Can you advise how we need to run the docker image? I tried to just run 'docker run -it ronalddddd/slackgun' but i get the following error. I can imagine i need to specify some of the variables shown on https://github.com/slickplaid/node-slack-mailgun, but as i have no idea on node, i am not sure what i need to do.

npm info it worked if it ends with ok
npm info using npm@3.10.8
npm info using node@v6.9.1
npm info lifecycle mailgun-slack-webhooks@1.0.0prestart: mailgun-slack-webhooks@1.0.0
npm info lifecycle mailgun-slack-webhooks@1.0.0start: mailgun-slack-webhooks@1.0.0

mailgun-slack-webhooks@1.0.0 start /usr/src/app
node slackgun.js

/usr/src/app/slackgun.js:7
if (!apikey) throw new Error('Missing mailgun api key');
^

Hi @Trouble123,

These are the environment variables used in the code, along with the port to use:

const apikey = process.env.npm_config_mailgun_key;
const hook = process.env.npm_config_slack_hook;
const channel = process.env.npm_config_slack_channel|| '#general';

// ...

app.listen(8080);

Feel free to help me update the readme, cheers!
