Kubernetes architecture typically consists of master nodes and worker nodes, with the master nodes managing the cluster and worker nodes running applications.
kubectl create is used to create new resources in Kubernetes, while kubectl apply is used to create or update resources based on a configuration file.
To give access to a new user on Kubernetes, you can create a Role or ClusterRole to define permissions and then create a RoleBinding or ClusterRoleBinding to associate the user with the Role or ClusterRole.
Kubernetes certificates include client certificates for authentication, server certificates for securing communication, and CA certificates for signing other certificates.
