Lab Environment

This lab utilizes Red Hat Product Demo System (RHPDS) to provision the lab environment. RHPDS uses Red Hat CloudForms to deploy infrastructure needed for our lab.

The infrastructure consists of 5 VMs as well as the overall network configuration. Red Hat OpenShift Container Platform 3.9 has already been deployed for this lab.

OpenShift environment for this lab consists of the following systems:

Access Your Lab Environment

Request an OPENTLC Account
Get access to filling the form at: https://account.opentlc.com/account/requestAccessForm.php

Set Password
After you have been notified by email that your account has been created, set your password using the temporary password provided in the email at: https://account.opentlc.com/account/setPasswordForm.php

Your username will be your Red Hat email address with "@" replaced by "-" (E.g if your Red Hat email address is jdoe@redhat.com, your login will be jdoe-redhat.com)

Provision Your Demo Environment

Log in to the Red Hat Product Demo System with your provided credentials.

RHPDS Login
If you have problems with access to the lab environment, send an email to internal-enablement@redhat.com.

Go to Services → Catalogs

Choose Catalog

Under Service Catalog → Red Hat Summit 2018, select IoT Solutions with Serverless arch.

On the right pane, click Order.

Order Lab

Review the information about lifecycle of the lab environment and how to extend it. Check box to confirm, click Submit

Start Lab
It takes ~30 minutes for lab to be provisioned and become accessible. You can get real-time status of the lab environment at https://www.opentlc.com/rhpds-status

You will be getting an email with information about how to access the lab environment.

The email will also provide the unique GUID needed to access the lab environment.

Access Lab environment

Interaction with the environment will be facilitated using several mechanisms listed below:

SSH

The primary method is using SSH to a workstation (bastion) host.

Upload your SSH key to www.opentlc.com/update to login and get into bastion.

$ ssh -i <your-private-key> lab-user@workstation-<GUID>.rhpds.opentlc.com

Change user to cloud-user

$ sudo -i -u cloud-user

OpenShift CLI

OpenShift features a Command Line Interface for interacting with the Platform. The executable has been already installed and is available from the bastion host.

Login to OpenShift with the following credentials

User: admin
Password: r3dh4t1!

oc login infranode-<GUID>.generic.opentlc.com:8443 +

You will see a warning related to insecure certificates. Given that this is a lab environment, it is OK to safely ignore these warnings. Type Y and hit Enter.

If successful, you will see the following output:

Login successful.

You don't have any projects. You can try to create a new project, by running

    oc new-project <projectname>

Welcome! See 'oc help' to get started.

The OpenShift CLI has been successfully configured and ready for use in the lab!

OpenShift Web Console

OpenShift features a rich user interface for managing resources on the platform.

Open a web browser and navigate to the following location

https://infranode-<GUID>.generic.opentlc.com:8443

Similar to the CLI, a warning will appear stating that insecure certificates are being utilized. Ignore the certificate warning and continue on to the login page.

Once again, use the following credentials at the login page

User: admin
Password: r3dh4t1!

The OpenShift catalog should be shown upon successful authentication
