Introduction ⒈
Replicationcontroller and ReplicaSet are running for the deployment of a specific number of pod on Kubermetes cluster. However, in some cases when we want to run with a specified pod on each node in the cluster will require more complex operations.
These include operations associated with the implementation of the system infrastructure pod level. For example, we want to run the log collection and resource monitors on each node. A typical example is the Kubernetes own kube-proxy process, it needs to run in order to make the service work on all nodes.
