odo is a CLI tool for creating applications on Kubernetes and OpenShift .
odo allows developers to concentrate on creating applications without the need to administer a cluster itself. Creating deployment configurations, build configurations, service routes and other Kubernetes or OpenShift elements are all automated by
Existing tools such as
oc are more operations-focused and require a deep understanding of Kubernetes and OpenShift concepts.
odo abstracts away complex Kubernetes and OpenShift concepts allowing developers to focus on what is most important to them: code.
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.
A project is your source code, tests, and libraries organized in a separate single unit.
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
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
A service is software that your component links to or depends on. Examples of services: MariaDB, MySQL.
A portable file responsible for your entire reproducable development environment.
Devfiles describe your development environment link. Click here for more information on Devfile.
