In general, the right question to ask yourself when designing Pods is, “Will these containers work correctly if they land on different machines?” If the answer is “no,” a Pod is the correct grouping for the

在之前我们提到过容器有6大基本功能组成,其中就包含系统系统资源的控制组,在默认情况下,docker中的容器对资源默认利用是没有任何限制的,因此它可以耗尽docker主机之上内核可以分配给当前容器的所有资源。为了避免出现容器对资源无限制的消耗导致的问题,在此之上,docker提供了一个途径用于控制内存,cpu,io。之前我们也提到...
