> [Umbrella] Improvements for user identity retrieval and ACLs
> ------------------------------------------------------------
>
> Key: YUNIKORN-649
> URL: https://issues.apache.org/jira/browse/YUNIKORN-649
> Project: Apache YuniKorn
> Issue Type: Improvement
> Components: shim - kubernetes
> Reporter: Amit Sharma
> Assignee: Amit Sharma
> Priority: Critical
> Fix For: 0.11
>
>
> The Kubernetes metadata does not carry user information by design. This can
> be referred here.
> [https://kubernetes.io/docs/reference/access-authn-authz/authentication/]
> Here is how Yunikorn determines the user from k8s metadata (Service Account)
> [https://github.com/apache/incubator-yunikorn-k8shim/blob/7648f29e50692fbb760480c586f8e3a1110eb15b/pkg/appmgmt/general/general.go#L126]
> The only thing close to any identity is a ServiceAccount. However, this is
> not the ideal way of looking at identities as there is no authentication
> mechanism for the service account directly. It relies on the authentication
> mechanism deployed on the cluster. The cluster authentication mechanism
> varies from deployment to deployment.
> There are 2 possible ways of doing this.
> 1) One generic solution can be to modify the source of the user from
> ServiceAccount to a Label/Annotation.
> 2) Extending point 1, instead of changing from service account to
> label/annotation, it can be a configurable field which defaults to
> Label/Annotation.
> While point 2 provides more user flexibility, it also reduces the structure
> or clear path that Yunikorn can follow in determining a user.
> Since Yunikorn is expected to be primarily deployed by owners of a Kubernetes
> platform rather than individual applications, we can share a structure using
> point 1 as a solution.
> Please share your thoughts.
