Is there a supported mechanism within the CML API v2 or cmlapi to generate temporary access keys with a specified expiration time? Yes. You may consider using cmlv2 api createV2Key [1]. I am able to get a apikey created for myself with ttl as 5 days ie 30 Mar 2025.  api request: curl -X POST "https://trimmed.cloudera.site/api/v2/users/ngopinath/v2_keys" -H "accept: application/json" -H "Authorization: Bearer trimmed.trimmed" -H "Content-Type: application/json" -d "{ \"comments\": \"test\", \"expiry_date\": \"2025-03-30\", \"username\": \"ngopinath\"}" api response: { "api_key": "trimmed.trimmed", "key_id": "trimmed", "created_at": "2025-03-25", "expiry_date": "2025-03-30", "comments": "test", "audiences": [ "API" ] } Since we have solution for Q#1, I presume following queries are invalidated. Let me know if you are able to proceed with api createV2Key. [1] https://docs.cloudera.com/machine-learning/cloud/rest-api-reference-ai-workbench/index.html#api-CMLService-createV2Key ... View more

I did some testing on my test workspace, below are the steps followed: > suspended the workspace > in AWS console, EC2 Autoscaling group set the min & desired count for the liftie infra node group as 0 > after completion of the update, validated in the CDP management console workspace details, I saw the count on Platform infra went to 0  > in the EC2 auto scaling group, set desired and min count as 2 in the liftie infra node group and once update completed, validated same on Workspace details > resumed the workspace and validated session launch was successful  Observations: Indeed, I was able to scale down all the AWS instance to 0 Suggestions: Would not suggest this on PROD or any critical environments [not sure what could be the effect on workspace that run on production scale] In case of non prod, test in thoroughly and "implement on your own risk" Alternates: Why do you consider backup and restore operations? When a workspace was not required, instead of suspending and manually scaling down the nodes can you consider backup the workspace and restore the backup when required. Anyhow, since you are planning for a complete shutdown it won't be a prod workspace. Backup/Restore could be an alternate option for non-prod workspace and again it is a cost effective option.   ...
