Is it possible to run kubectl within a container within the cluster?

I have a kubernetes cluster, and I basically have an authenticated api for deploying tasks within the cluster without having kubectl etc set-up locally. I'm aware of the client libraries etc for the Kubernetes api, however they don't seem to support all of the different primatives etc (including some custom ones like Argo). So I just wondered if there was a way I could effectively run $ kubectl apply -f ./file.yml within a container on the cluster?

Obviously I can create a container with kubectl installed, but I just wondered how that could then 'connect' to the Kubernetes controller?

I found that the roffe/kubectl image works well for running a kubectl apply -f to deploy to my cluster. However, you do need to use a ClusterRole and ClusterRoleBinding "attached" to your ServiceAccount, (and the serviceAccount named in your kubectl container), to deploy to any other namespaces.
