Learn how to use the OpenShift Container Platform to build and deploy an application with a data backend and a web frontend.
- OpenShift Web Console and Perspectives
occommand line tool
- Building applications from source on OpenShift
- OpenShift REST API
- Public URLs and OpenShift Routes
Be able to provide a great experience for both Developers and System Administrators to develop, deploy, and run containerized applications using OpenShift. Developers should love using OpenShift because it enables them to take advantage of both containerized applications and orchestration without having to know the details. Developers are free to focus on their code instead of spending time writing Dockerfiles and running docker builds.

Getting Started with OpenShift for Developers
Step 1 - Exploring The Command Line
Command Line Interface (CLI)
The OpenShift CLI is accessed using the command oc. From here, you can administrate the entire OpenShift cluster and deploy new applications.
The CLI exposes the underlying Kubernetes orchestration system with the enhancements made by OpenShift. Users familiar with Kubernetes will be able to adapt to OpenShift quickly. oc provides all of the functionality of kubectl, along with additional functionality to make it easier to work with OpenShift. The CLI is ideal in situations where you are:
1) Working directly with project source code
2) Scripting OpenShift operations
3) Restricted by bandwidth resources and cannot use the web console
In this tutorial, we're not focusing on the OpenShift CLI, but we want you to be aware of it in case you prefer using the command line. You can check out our other courses that go into the use of the CLI in more depth. Now, we're just going to practice logging in so you can get some experience with how the CLI works.
Exercise: Logging in with the CLI
Let's get started by logging in. Your task is to enter the following into the console:
oc login -u developer
When prompted, enter the following password:
Next, you can check if it was successful:
oc whoami should return a response of:
In the next step, we'll get started with creating your first project using the web console.
