Kubernetes Pod含义
官网文档 https://kubernetes.io/docs/concepts/workloads/pods/pod/
什么是Pod?
Pod的本身含义是一群鲸鱼的意思, 而Docker的Logo刚好是🐳。所以简单说pod就是一组容器。(不一定是docker container) pod里的容器共享存储,网络和运行的容器环境。共享的东西包括cgroup, 命名空间, Ip, 端口和其他隔离方面的东西
pod内部通讯
由于pod里面的容器共享ip, 容器间的通讯可以通过内部进程通信(SystemV semaphores, POSIX shared memory)或localhost.
