Running garie-browsertime

You can get setup with the basics in a few minutes.

First clone the repo.

git clone https://github.com/eea/garie-browsertime.git

Next setup you're config. Edit the config.json and add websites to the list.

{
  "plugins":{
        "browsertime":{
            "cron": "0 */4 * * *"
        }
    },
  "urls": [

    }
  ]
}

Once you finished edited your config, lets build our docker image and setup our environment.

docker build -t garie-browsertime . && docker-compose up

This will build your copy of garie-browsertime and run the application.
