Goal
Learn how to deploy an application on OpenShift with the web console and with the oc
command line tool.
Concepts
- Deploying existing container images on an OpenShift cluster
- OpenShift Web Console’s Topology view
- OpenShift Projects and Applications
- OpenShift
oc
tool’snew-app
subcommand
Use case
You can deploy a container image on an OpenShift cluster to make the application easier to manage, scale, connect and monitor.
This OpenShift cluster will self-destruct in one hour.
In this course you learned about deploying an existing container image to OpenShift.
Continue Learning
You can continue learning more about OpenShift and how to develop applications on the platform by completing other tutorials at https://learn.openshift.com.

Run OpenShift Locally with CodeReady Containers
CodeReady Containers allows you to run a minimal, pre-configured OpenShift 4 cluster on your local machine. The project supports Windows 10, macOS, and Linux. To find out more or download CodeReady Containers, visit https://developers.redhat.com/products/codeready-containers/overview

Steps
Deploying Applications From Images
Topic 1 - Creating an Initial Project
Before we get started, you need to login and create a project in OpenShift to work in.
To login to the OpenShift cluster used for this course from the Terminal, run:
oc login -u developer -p developer
This will log you in using the credentials:
- Username:
developer
- Password:
developer
You should see the output:
Login successful.
You don't have any projects. You can try to create a new project, by running
oc new-project <projectname>
To create a new project called myproject
run the command:
oc new-project myproject
You should see output similar to:
Now using project "myproject" on server "https://openshift:6443".
You can add applications to this project with the 'new-app' command. For example, try:
oc new-app django-psql-example
to build a new example application in Python. Or use kubectl to deploy a simple Kubernetes application:
kubectl create deployment hello-node --image=gcr.io/hello-minikube-zero-install/hello-node
Switch to the Console and login to the OpenShift web console using the same credentials you used above.
This should leave you at the list of projects you have access to. As we only
created the one project, all you should see is myproject
.
Click on myproject
and you should then be at the Overview page for
the project. Select the Developer perspective for the project instead of the Adminstrator perspective in the left hand side menu. If necessary click on the hamburger menu icon top left of the web console to expose the left hand side menu.
As the project is currently empty, no workloads should be found and you will be presented with various options for how you can deploy an application.
