blue-green-deployment's Introduction

Pivotal Cloud Foundry Blue Green Deployment Example

Steps:

    - Build the application using Maven: mvn clean package
    - Set your pivotal api end point. run >>cf api <give api endpoint here>
    - Login with your pivotal credentials : >> cf login -u  <login email>
    - Deploy your "Blue" Application: >>cf push -f manifest-blue.yml      //(-f to select given manifest file and not default manifest file)
    - Deploy your "Green" Application: >>cf push -f manifest-green.yml

Now Map Application Route to both Blue and Green Routes

After pushing both the applications to Pivotal Cloud Foundry we need to create an application route url and configure it as a domain to both green and blue url's.

In this example, we have pcf-blue-${random-word} and pcf-green-${random-word} url's where random-word is generated automatically. Let's create an application route url as like below, Application Url: pcf-blue-or-green-${random-word}-domain-name

Run the below commands

Blue:
cf map-route pcf-blue-${random-word}-domain-name -n pcf-blue-or-green-${random-word}

Green:
cf map-route pcf-green-${random-word}-domain-name -n pcf-blue-or-green-${random-word}

run the below command to check the application routes
>>cf routes

use the below command to unmap an url from the application url
>>cf unmap-route blue-url -n application-route-url
