we have different aws accounts, only set users in one main account and developers will perform their development on to another account, in the second account, we need to set up a kubernetes cluster, and developers could be able to spawn namespace as they need. In kubernetes access rule, only the one who created the cluster has access to the cluster, other users has to be added to configmap one by one, is there any quick way that after I create a cluster, the other users could automaticlly get access and create namespace as they needed?

Thanks!
