Create IAM roles and instance profile pair
This step describes the role and instance profile pair that you will create and attach to EKS master and worker instances at runtime. This step is required in customer environments where write permissions are not provided to Cloudera Data Engineering (CDE). The roles created here are used exclusively within the customer's account. This step needs to be performed in the user’s AWS console.
Use the following CloudFormation template to create the following:
- IAM role called
cdp-eks-master-role - IAM role and Instance Profile pair called
cdp-liftie-instance-profile
- To apply the template, you need to provide values for the following parameters in the
AWS console CloudFormation wizard:
Stack Name: Provide an appropriate name. (Example: compute-precreated-roles-and-instanceprofile)TelemetryLoggingBucket: Name of the log bucket (just the name, not s3://) (Example :compute-logging-bucket)TelemetryLoggingEnabled: Set it to trueTelemetryLoggingRootDir: Keep the default value (which is cluster-logs)TelemetryKMSKeyARN: If the telemetry bucket is encrypted, give the KMS Key ARN. Default value is null.
- On the last page of the wizard, select the checkbox to allow creation of IAM resources with special names. If not selected, CloudFormation prepends the provided name with random prefixes to ensure uniqueness.
The result of this procedure resembles the following:
Use the following CloudFormation template for this process.
