Admission controller ServiceAccount is enabled
Set up the kubernetes integration.
Description
Automate service accounts management.
Rationale
When you create a pod, if you do not specify a service account, it is automatically assigned the default service account in the same namespace. You should create your own service account and let the API server manage its security tokens.
Audit
Run the following command on the master node:
ps -ef | grep kube-apiserver
Verify the --disable-admission-plugins argument is set to a value that does not include ServiceAccount.
Follow the documentation and create ServiceAccount objects as per your environment. Then, edit the API server pod specification file /etc/kubernetes/manifests/kube-apiserver.yaml on the master node and ensure that the –disable-admission-plugins parameter is set to a value that does not include ServiceAccount.
Impact
None.
Default value
By default, ServiceAccount is set.
