Run `kubectl apply` using yaml stored in a variable - powershell

Question

I have a resource I want to apply as part of an automated script (running in powershell). I would rather not have to write it out to a file then have to deal with cleaning it up.
Is it possible to apply the yaml as part of a script?
Something similar to this:
$myYaml = #'
apiVersion: "rbac.authorization.k8s.io/v1"
kind: RoleBinding
metadata:
name: ServiceAccount-clusteradmin
roleRef:
apiGroup: "rbac.authorization.k8s.io"
kind: ClusterRole
name: ClusterAdmin
subjects:
- apiGroup: "rbac.authorization.k8s.io"
kind: User
name: "MyAdminServiceAccount"
'#
kubectl apply #myYaml
Clearly, the kubectl command above does not work.
My question is: Is a way to apply this yaml without creating a file (using powershell)?

Answer 1

myYaml is a variable having the data:
$myYaml = #'
apiVersion: "rbac.authorization.k8s.io/v1"
kind: RoleBinding
metadata:
name: ServiceAccount-clusteradmin
roleRef:
apiGroup: "rbac.authorization.k8s.io"
kind: ClusterRole
name: ClusterAdmin
subjects:
- apiGroup: "rbac.authorization.k8s.io"
kind: User
name: "MyAdminServiceAccount"
'#
Perform the following to echo the contents of $myYaml variable and pipe it to kubectl apply -f -, here last - is for piped input.
$myYaml |kubectl.exe apply -f -
rolebinding.rbac.authorization.k8s.io/ServiceAccount-clusteradmin created
kubectl.exe get rolebindings
NAME ROLE AGE
ServiceAccount-clusteradmin ClusterRole/ClusterAdmin 18s
This is very similar to linux environment where echo "$var" |kubectl apply -f - is used to perform same action.
