In the interest of time we have deployed everything required to run Karpenter for this workshop. All the pre-requisites and dependencies have been deployed. The resources deployed can befound in this CloudFormation Template (eks-spot-workshop-quickstarter-cnf.yml). The template deploys resourcess such as (a) An AWS Cloud9 workspace with all the dependencies and IAM privileges to run the workshop (b) An EKS Cluster with the name eksworkshop-eksctl and (c) a EKS managed node group with 2 on-demand instances.

Getting access to Cloud9

In this workshop, you’ll need to reference the resources created by the CloudFormation stack.

  1. On the AWS CloudFormation console, select the stack name eks-spot-workshop-quickstart-cnf in the list.

  2. In the stack details pane, click the Outputs tab.

cnf_output

It is recommended that you keep this tab / window open so you can easily refer to the outputs and resources throughout the workshop.

you will notice additional Cloudformation stacks were also deployed which is the result of the stack that starts with mod-. One to deploy the Cloud9 Workspace and two other to create the EKS cluster and managed nodegroup.

Launch your Cloud9 workspace

Note: Cloud9 normally manages IAM credentials dynamically. This isn’t currently compatible with the EKS IAM authentication, so we will disable it and rely on the IAM role instead. To do so, run the following commands in the Cloud9 workspace:

aws cloud9 update-environment --environment-id ${C9_PID} --managed-credentials-action DISABLE
rm -vf ${HOME}/.aws/credentials

Validate the IAM role

Use the GetCallerIdentity CLI command to validate that the Cloud9 IDE is using the correct IAM role.

aws sts get-caller-identity

If the Arn contains the role name from above and an Instance ID, you may proceed.
