这里指定“同一位置” 是通过 topologyKey 来定义的,topologyKey 对应的值是 node 上的一个标签名称,比如各别节点zone=A标签,各别节点有zone=B标签,pod affinity topologyKey定义为zone,那么调度pod的时候就会围绕着A拓扑,B拓扑来调度,而相同拓扑下的node就为“同一位置”。 如果基于各个节点kubernetes.io/hostname标...
~~~ 比如说这个拓扑域的key是按照主机名来区分的, ~~~ 在亲和力配置中,配置了拓扑域的概念, ~~~ 这个拓扑域的key是这个/kubernetes.io/hostname,是按照这个key来划分的拓扑域 ~~~ 又因为它的key是这个值,只有key和value是同样的值,才属于同一个拓扑域, ~~~ 但是又因为每一个主机名不可能是不一样的,...

With all of the key edge loops placed, we need to work on reducing the number of loops coming fro mthe toe area towards the ankle. Reducing the number of loops is necessary so that we don’t end up with overly dense topology at the ankle and legs where such high density topology isn...
the use of a star topology within a hybrid network can enhance fault tolerance, while including a mesh topology can improve data routing efficiency. however, keep in mind that a poorly designed hybrid network can also lead to performance issues, so careful planning is key. can i use a hybrid...
