OpenShift Online is designed for building and deploying applications. Depending on how much you want to involve OpenShift Online in your development process, you can choose to:
focus your development within an OpenShift Online project, using it to build an application from scratch then continuously develop and manage its lifecycle, or
bring an application (e.g., binary, container image, source code) you have already developed in a separate environment and deploy it onto OpenShift Online.
You can begin your application’s development from scratch using OpenShift Online directly. Consider the following steps when planning this type of development process:
Initial Planning
What does your application do?
What programming language will it be developed in?
Access to OpenShift Online
Access OpenShift Online by logging in and creating an account at https://openshift.com/get-started/.
Develop
Using your editor or IDE of choice, create a basic skeleton of an application. It should be developed enough to tell OpenShift Online what kind of application it is.
Push the code to your Git repository.
Generate
Create a basic application using the oc new-app
command. OpenShift Online generates build and deployment configurations.
Manage
Start developing your application code.
Ensure your application builds successfully.
Continue to locally develop and polish your code.
Push your code to a Git repository.
Is any extra configuration needed? Explore the Developer Guide for more options.
Verify
You can verify your application in a number of ways. You can push your changes
to your application’s Git repository, and use OpenShift Online to rebuild and redeploy
your application. Alternatively, you can hot deploy using rsync
to synchronize
your code changes into a running pod.
Another possible application development strategy is to develop locally, then use OpenShift Online to deploy your fully developed application. Use the following process if you plan to have application code already, then want to build and deploy onto an OpenShift Online installation when completed:
Initial Planning
What does your application do?
What programming language will it be developed in?
Develop
Develop your application code using your editor or IDE of choice.
Build and test your application code locally.
Push your code to a Git repository.
Access to OpenShift Online
Access OpenShift Online by logging in and creating an account at https://www.openshift.com/get-started/.
Generate
Create a basic application using the oc new-app
command. OpenShift Online generates build and deployment configurations.
Verify
Ensure that the application that you have built and deployed in the above Generate step is successfully running on OpenShift Online.
Manage
Continue to develop your application code until you are happy with the results.
Rebuild your application in OpenShift Online to accept any newly pushed code.
