4. Services

Cloud Foundry has multiple built-in services which we can find in market place and also user can define his own service and use in application. Built-in services like mysql database, redis server and many more are found in market place. In below command we use mysql database service and use in our application

1. Getting or Provisioning MySQL Database

cf create-service p-mysql 100mb-dev attendee-mysql
 Note : p-mysql is service name, 100mb-dev is plan name, attendee-mysql is user defined database name

2. Binding Services to Application

 cf bind-service attendee-service attendee-mysql
 Note : bind-service is command, attendee-service is application Name, attendee-mysql is the service which is binding (MySQL database in this case) . If service is not working then run cf restage appName Command  or  cf restart

5. Blue Green Deployment

Application should be running in two or more instance to use blue green deployment.

  • Assume we have two version of a application appName and appName-v2
  • Using cf push we deploy first version of application(appName)
  • We need to scale application horizontally for two or more instance
  • We deploy new version of the application with different route name and then test application
  • After testing is complete use map-route command to route newer version to production domain. After executing command we see warning message saying route already exist as older version is also running

    cf map-route appName-v2 hostname -n subdomain.ashwin-shetty.com

  • Scale down older version and Scale up the new version of the application
  • Now unmap the older version of the application so that only one version is running in production

    cf unmap-route appName hostname -n subdomain.ashwin-shetty.com
