How to deploy Grails to Jelastic cloud

Grails is an innovative, high-productivity framework that follows the principle of "Convention over Configuration," making it quite popular. It provides a stand-alone development environment while maintaining a simplicity that allows the developer to focus on what really matters: creating high quality, easy to use applications that users love. Grails supplients Java application development quite easily because it is built on Spring and based on Groovy.

So, how do you get all the benefits of using Grails and the Cloud? Easy. Use Jelastic!


A. Create the Application

  1. Go to grails.org and download the lastest version of Grails.


  2. Unzip the package you have just downloaded.
  3. Add the environment variables (this step is optional):
    • GRAILS_HOME (...\grails-2.0.0) specifies to the path where you extracted the archive;
    • PATH (...\grails-2.0.0\bin) contains the path to the bin directory.

  4. Create your app using the command line.

  5. With environment variables (C:\grails on Windows,~/grails on Linux):
    ...\grails-1.3.7 grails create-app {app_name}
    Without environment variables:
    ...\grails-1.3.7\bin\grails create-app {app_name}
    NOTE: application will be created in directory C:\grails-1.3.7\bin\5
  6. Create .war archive with just one command:

With environment variables (C:\grails on Windows,~/grails on Linux):
...\grails-1.3.7\{app_name} grails war {app_name}.war
Without environment variables (C:\grails on Windows,~/grails on Linux):
...\grails-1.3.7\bin\{app_name} ...\grails-1.3.7\bin\grails war {app_name}.war
WAR archive will be saved at C:\grails-1.3.7\bin\{app_name}\
B. Create the Environment

  1. Log into the
    Jelastic Manager
  2. Use Jelastic to create a new environment.

  3. In the Environment topology dialog pick your application server (e.g. Tomcat 6) and type your environment name, for example, Grails, then click on Create button.


  4. It will take just a minute for your environment to be created.


C. Upload the Java Package
  1. Upload your WAR file to the Deployment manager.

  2. Once the package uploaded to Jelastic, deploy it to your environment.


That's it. Launch your application and enjoy!
