kubernetes - k8s replicaSet 状态困惑

Question

我有两项服务:

bayonetta:后端 clusterIp 服务，replicaset=2

隐藏:前端节点端口服务，replicaset=1

我跑了 kubectl get all .我看到 replicaSet 部分的第 3 行和第 4 行所有内容都为 0，为什么在没有可用内容时我们有这两行？

replicaset.apps/bayonetta-deployment-5b75868d89   2         2         2       3h36m
replicaset.apps/bayonetta-deployment-5c65f74c8b   0         0         0       176m
replicaset.apps/hide-deployment-575b6bc68d        0         0         0       3h12m
replicaset.apps/hide-deployment-66d955986b        1         1         1       155m

Answer 1

您可能更新了您的 Deployments ，这导致扩大新的 ReplicaSets并缩小现有的规模。查看 Kubernetes 文档 here ，举个例子:

Run kubectl get rs to see that the Deployment updated the Pods by creating a new ReplicaSet and scaling it up to 3 replicas, as well as scaling down the old ReplicaSet to 0 replicas.

kubectl get rs

The output is similar to this:

NAME                          DESIRED   CURRENT   READY   AGE
nginx-deployment-1564180365   3         3         3       6s
nginx-deployment-2035384211   0         0         0       36s
