Planning Your Development Process
Overview
OKD is designed for building and deploying applications. Depending on how much you want to involve OKD in your development process, you can choose to:
focus your development within an OKD 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 OKD.
Using OKD as Your Development Environment
You can begin your application’s development from scratch using OKD 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 OKD
- OKD should be installed by this point, either by yourself or an administrator within your organization.
Develop
Using your editor or IDE of choice, create a basic skeleton of an application. It should be developed enough to tell OKD what kind of application it is.
Push the code to your Git repository.
Generate
- Create a basic application using the
oc new-app
command. OKD 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 OKD to rebuild and redeploy your application. Alternatively, you can hot deploy using
rsync
to synchronize your code changes into a running pod.
Bringing an Application to Deploy on OKD
Another possible application development strategy is to develop locally, then use OKD 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 OKD 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 OKD
- OKD should be installed by this point, either by yourself or an administrator within your organization.
Generate
- Create a basic application using the
oc new-app
command. OKD 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 OKD.
Manage
Continue to develop your application code until you are happy with the results.
Rebuild your application in OKD to accept any newly pushed code.
