Red Hat CDK Easy Install Demo

If you are looking to develop containerized applications for Red Hat Enterprise Linux systems, the Red Hat Container Development Kit (CDK) can help you by providing a Red Hat container development environment you can install locally. It includes the same container development and run-time tools used to create and deploy containers for large data centers.

To get started with the provided pre-configured containers, see the online documentation. If you are fairly new to container development, see the online Getting Started with Container Development.

Option 1 - Install on your machine

1. Download and unzip.

2. Add products as needed, see installs directory for list, free downloads here.

3. Run 'init.sh' or 'init.bat' file. Windows init.bat will point you to the windows installer.

4. Read and follow displayed instructions and enjoy the Red Hat Container Development Kit (CDK) on your local machine!

Getting started

The following containers can be started after installing this project for you to start exploring:

OpenShift Enterprise - a containerized version of OpenShift Enterprise can be started that can be accesses through a Web console in your browser or via the OpenShift command line tools. Explore your very own private PaaS developer experience with this container.

 $ cd ./target/cdk/components/rhel/rhel-ose
 $ vagrant up

 OpenShift console available at: https://10.1.2.2:8443/console
 Login as 'admin' with password 'admin'

Kubernetes - a container to set you up for exploring a Kubernetes cluster. It is setup to run as an all-in-one Kubernetes master to manage pods and node for running multiple pods.

 $ cd ./target/cdk/components/rhel/misc/rhel-k8s-singlenode-setup
 $ vagrant up 

Notes

Should your local network DNS not handle the resolution of the above address, giving you page not found errors, you can apply the following to your local hosts file:

$ sudo vi /etc/hosts

# add host for CDK demo resolution.
10.1.2.2   10.1.2.2   10.1.2.2

If you halt your CDK image, when restarting you may encounter 'Application is not available' when trying to reach a project URL, just locate and remove the router image as follows:

$ oc get pods -n default

NAME                       READY     STATUS             RESTARTS   AGE
docker-registry-1-deploy   0/1       DeadlineExceeded   0          9h
docker-registry-2-gfgc3    1/1       Running            0          9h
router-1-9ri9d             2/2       Running            0          9h

$ oc delete pod router-1-9ri9d -n default

This will restart the router and resolve your application URLs.
