In Charmed Kubeflow (CKF), as in upstream Kubeflow, a profile denotes a collection of resources, roles, and credentials.
Anything a user does within Kubeflow is associated with a profile. A profile can be for individual use or shared with multiple users, and must be owned by at least one user. A user can even have multiple profiles.
The profile name is what shows in the header of the Kubeflow dashboard. If you have access to multiple profiles, you can switch between them there.
For each profile, Kubeflow creates a namespace of the same name that encapsulates the resources specific to that profile.
See Kubeflow profiles and namespaces for more details. Refer to How to manage profiles for learning about managing profiles.
