What is the maximum number of containers allowed in a single Pod in Kubernetes?

There is no hard limit on the number of containers in a single Pod in Kubernetes, but in practice, it is recommended to use no more than 2-3 containers. The main idea of a Pod is a group of tightly coupled containers that share resources and network. Too many containers in one Pod complicate management and reduce flexibility. Usually, one main container and several auxiliary (sidecar) containers are the optimal approach.
