Workshop

Connect to the OpenShift Cluster

Connect to your EC2 Instance #

We’ve prepared an Ubuntu Linux instance in AWS/EC2 for each attendee.

Using the IP address and password provided by your instructor, connect to your EC2 instance using one of the methods below:

• Mac OS / Linux
  • ssh splunk@IP address
• Windows 10+
  • Use the OpenSSH client
• Earlier versions of Windows
  • Use Putty

Set the Workshop Participant Number #

The instructor will provide each participant with a number from 1 to 30. Store this in an environment variable, and remember what it is, as it will be used throughout the workshop:

export PARTICIPANT_NUMBER=<your participant number>

Install the OpenShift CLI #

To access the OpenShift cluster, we’ll need to install the OpenShift CLI.

We can use the following command to download the OpenShift CLI binary directly to our EC2 instance:

curl -L -O https://mirror.openshift.com/pub/openshift-v4/x86_64/clients/ocp/stable/openshift-client-linux.tar.gz

Extract the contents:

tar -xvzf openshift-client-linux.tar.gz

Move the resulting files (oc and kubectl) to a location that’s included as part of your path. For example:

sudo mv oc /usr/local/bin/oc
sudo mv kubectl /usr/local/bin/kubectl

Connect to the OpenShift Cluster #

Ensure the Kube config file is modifiable by the splunk user:

chmod 600 /home/splunk/.kube/config

Use the cluster API URL and password provided by the workshop organizer to log in to the OpenShift cluster:

oc login https://api.<cluster-domain>:443 -u participant$PARTICIPANT_NUMBER -p '<password>'

Ensure you’re connected to the OpenShift cluster:

oc whoami --show-server
