With network policies, which permit access within the namespace, microservices can communicate with one another. This is common for bootstrap, master and worker nodes. Static IP addresses and MAC addresses do not have to be used at the same time, you may use them Four basic network communication flows arise within every cluster: Pod communication over the local host network (127.0.0.1) Containers that communicate within their pod use the local host network address. However, the concept of sidecar containers gives developers an easy tool to attach containers, with the needed development tools and utilities, to a microservice pod.
