I am getting following errors in syslog while trying to systemctl start kube-apiserver
Dec 8 16:29:42 mySystem systemd8722: kube-apiserver.service: Failed to execute command: Permission denied Dec 8 16:29:42 mySystem systemd8722: kube-apiserver.service: Failed at step EXEC spawning /usr/local/bin/kube-apiserver: Permission denied Dec 8 16:29:42 mySystem systemd1: kube-apiserver.service: Main process exited, code=exited, status=203/EXEC Dec 8 16:29:42 mySystem systemd1: kube-apiserver.service: Failed with result 'exit-code'.
MY sysd config looks like this:

For a background I am doing a manual kube deployment for some learning purpose.
Within the information that you provided I suspect that you have some permission/privileges issue which indicates this error:
"Failed at step EXEC spawning /usr/local/bin/kube-apiserver: Permission denied"
You are trying to start the service with User=kube-apiserver
which I think don`t have enough privileges.

If you wish to learn how to bootstrap Kubernetes cluster by yourself there are two good ways to do that:
1 . With Kubeadm
which allows you to create and manage Kubernetes clusters. It performs the actions necessary to get a minimum viable, secure cluster up and running in user friendly way.
Here's how to install it, and here is information how to create your cluster.
It has a section about manual bootsrapping kubernetes cluster with usage of Kubernetes binaries and section about API server.
