{odo-title-full} ({odo-title}) is a fast and easy-to-use CLI tool for creating applications on {product-title}. {odo-title} allows developers to concentrate on creating applications without the need to administrate an {product-title} cluster itself.
|
|
Creating deployment configurations, build configurations, service routes and other {product-title} elements are all automated by {odo-title}.
|
|
|
|
Existing tools such as `oc` are more operations-focused and require a deep understanding of Kubernetes and {product-title} concepts. {odo-title} abstracts away complex Kubernetes and {product-title} concepts allowing developers to focus on what is most important to them: code.

* Completely client based. No server is required within the {product-title} cluster for deployment.
|
|
* Official support for Node.js and Java components.
|
|
* Partial compatibility with languages and frameworks such as Ruby, Perl, PHP, and Python.
|
