The purpose of this article is to show how quickly and easily deploy Grails application to Cloud Foundry platform.
What is Cloud Foundry?
Cloud Foundry is an open platform as a service, providing a choice of clouds, developer frameworks and application services. Initiated by VMware, with broad industry support, Cloud Foundry makes it faster and easier to build, test, deploy and scale applications. It is an open source project and is available through a variety of private cloud distributions and public cloud instances, including CloudFoundry.com.
To make a use of this article you’ll need to have Grails framework installed.
To check if Grails is properly installed, use
You should see something like
Grails version: 2.0.0
If you haven’t, just follow the Grails Getting Started Guide.
Let’s the fun begin
The whole process is extraordinary simple! Just do the following steps.
1. Create Grails app
grails create-app cloud_foundry_example
2. Change your working directory to a new application directory
3. Install Cloud Foundry plug-in
grails install-plugin cloud-foundry
4. Configure your Cloud Foundry credentials
You can configure it in both grails-app/conf/Config.groovy and in ~/.grails/settings.groovy. Since the file will contain sensitive, it’s not recommended to put it in source control. That’s why the second option is considered the best practice.
So, configure your credentials using
grails.plugin.cloudfoundry.username = "<your_username>" grails.plugin.cloudfoundry.password = "<pass>"
5. Test your config
The output should look like
VMware's Cloud Application Platform For support visit http://support.cloudfoundry.com Target: http://api.cloudfoundry.com (v0.999) User: <your_username> Usage: Memory (0B of 2.0G total) Services (0 of 16 total) Apps (0 of 20 total)
6. Deploy your app!
grails prod cf-push
You’ll be asked about the application URL, and also about some persistence services (in the time of writing: MySQL and PostgreSQL). I advise to accept default address and chose one of these services.
If you want to re-deploy after some changes, just do
grails prod cf-update
The app is deployed and ready to work. A proof? PartyPlanner app.
In next part I’ll describe how to configure different services in Cloud Foundry.
