Getting Started on Heroku with Go

1. Created a heroku account.
2. Installed heroku toolbelt.
3. Logged in to heroku using the CLI and clone the app locally.

rwatsh@Watshs-MBP  ~  heroku login heroku-cli: Installing CLI... 19.73MB/19.73MB Enter your Heroku credentials.

1. 4 Deploy the app.

1. 5.App gets deployed at - https://safe-plains-74038.herokuapp.com/ url.
2. 6The app uses the following procfile (a configuration file specific to Heroku) with the following contents, where, web = process type which tells heroku to associate a web listener with the app.

web: go-getting-started

1. 7The go app runs in a dyno = a heroku container which executes all commands specified in Procfile. A Free dyno goes to sleep after 30 mins of inactivity and a web request will wake it up (there is a delay due to this). A free dyno can be active no more than 18 hrs a day.

heroku ps Free quota left: 17h 53m === web (Free): go-getting-started (1) web.1: up 2016/05/11 17:04:54 -0700 (~ 6m ago)

1. 8.There is a Godeps.json which defines the dependency and is how heroku knows the app is a Go app. This app is dependent on Gin, a Http framework.
2. 9The app can be run locally as: heroku local web
3. 10.  Create a new route /mark, test locally and then push the changes to heroku.
