Question: Does Nooba supports Security Token Service ?

[anuj812]

Does S3 compatible storage through Nooba supports Security Token Service ? We tried using aws sts commands on OCS object storage on Openshift 4.5 but didn't get any success. We were looking to migrate from minio to ocs but seeems to be a problem as it doesn't seems to be supporting STS . We tried from AWS Java sdk as well as aws cli as well 'aws sts' commands. Please confirm.

@jindong-ibm @anuj812 Hello, We do not have STS. Previously, I've created a POC that implements STS and IAM in NooBaa. The POC allowed configuring Azure's AD with NooBaa and using it (Azure AD) as a web identity provider. Sadly due to other higher priority tasks, we've dropped the POC and didn't advance with it.

I would like to get more input on your use cases and the flows that you are interested in.

1. What operations are you using in the STS (if possible with a deep dive details of the configurations and options as well), do you use SAML, web identity, or other methods?
2. Do you need anything besides STS (IAM for example to manage the rules for the STS?)
3. Who is the identity provider for your STS and how do you configure it? (AWS AD FS, Azure AD, others?)
4. How do you sync NooBaa's IAM roles (if you have any) with the identity providers?

Basically, I'm interested in any info that I can get regarding your plans and current usage. This will allow me to understand the gaps and what are the actual use cases that interest you. Thank you.

1. We create a subuser and then just use the AssumeRole feature to get the session creds which consist of temporary access key, secret key and session token. I can share pseudo code of Java client leverage STS from AWS SDK to confirm the capability we are using. We are not using any web identity so far and usage restricted to assume role only.
2. No IAM
3. No identity provider so far, we create subuser directly in atleast in MinIO using add user commands. We use admin user similar to [email protected] in OCS. in nooba, problem is we are not able to create a subuser. We try to leverage the Nooba Management Console to create one account/subuser but we were not able to apply permission at sub-user level and later when tried to assume role operation , getting 403 issue.
4. Since no IAM so no sync. Pseudo Code for Current Usage.

@jeniawhite and @nimrod-becker Please check above post ^^ Can you help to give any suggestion/workaround? Team need to evaluate this situation and come up with "plan B" if Nooba can not work around the issue. So I hope we can have a final "yes, can do" or "no, cannot" answer today or tomorrow, to help team make decision. Thanks for your help.

[nimrod-becker]

@jindong-ibm thanks for the info, it does scope what's needed and help us understand he exact request.

It's not available now, but assessing the needed work, there isn't a lot in order to support this. We won't be able to pick this up in the immediate future but can tackle it a little further down the road. On the other hand, we can help if you want to give it a stab and add this support.

[jindong-ibm]

Thanks much for reply @nimrod-becker . We are planning to use Red Hat OCS (openshift container storage) which using noobaa for object storage. Yes, we are happy to give a try when you have it support.

If it is alright, I hope to keep this item open so to track this support and communicate. But if you have any other channel or other way, please let us know, we are happy to follow. Thanks

[nimrod-becker]

We will keep the bug open of course :)
