odo is a fast, iterative, and straightforward CLI tool for developers who write, build, and deploy applications on Kubernetes and OpenShift.
Existing tools such as kubectl and oc are more operations-focused and require a deep-understanding of Kubernetes and OpenShift concepts. odo abstracts away complex Kubernetes and OpenShift concepts for the developer.
odo is designed to be simple and concise with the following key features:
-
Simple syntax and design centered around concepts familiar to developers, such as projects, applications, and components.
-
Completely client based. No additional server other than Kubernetes or OpenShift is required for deployment.
-
Official support for Node.js and Java components.
-
Detects changes to local code and deploys it to the cluster automatically, giving instant feedback to validate changes in real time.
-
Lists all the available components and services from the cluster.
- Project
-
A project is your source code, tests, and libraries organized in a separate single unit.
- Application
-
An application is a program designed for end users. An application consists of multiple microservices or components that work individually to build the entire application. Examples of applications: e-Shop, Hotel Reservation System, Online Booking
- Component
-
A component is a set of Kubernetes resources which host code or data. Each component can be run and deployed separately. Examples of components: Warehouse API Backend, Inventory API, Web Frontend, Payment Backend
- Service
-
A service is software that your component links to or depends on. Examples of services: MariaDB, MySQL.
- Devfile
-
A portable file responsible for your entire reproducible development environment.
Devfiles describe your development environment link. Click here for more information on Devfile.

We work in 3-week sprint cycles. On a week when the sprint starts we have two planning calls:
-
"Sprint Planning Preparation and Issue Triage" - on Monday
-
"Sprint Planning" - on Wednesday
On top of our sprint planning calls, we have our regular "odo contributors call" (biweekly on Tuesdays). This is where we discuss technical challenges and anything related to odo development.
All our calls are open to public. You are welcome to join any of our calls.
You can find the exact dates of all scheduled odo calls together with sprint dates in the odo calendar (iCal format).
To participate in the calls, please join odo-dev Google group. When you join the group, you will automatically get invites to all odo related calls and get permissions to all necessary documents.
Below is a roadmap for odo where 2.1, 2.2 and 2.3 are odo versions.
-
