Python pykube-RollingUpdater规模副本

利用pykube模块

有人知道如何利用RollingUpdate#缩放功能来增加部署副本吗

---

我正在努力从代码库中找到解决方法。

成功地解决了这个问题-要将副本增加到3个，您可以执行以下操作：

deployments = pykube.Deployment.objects(kubernetesApi).filter(namespace="my-namespace")

for dp in deployments:
    if dp.obj["metadata"]["name"] == "my-deployment":
        dp.replicas = 3
        pykube.Deployment(kubernetesApi, dp.obj).update()

@eggsy84的答案会起作用，但并不优雅，因为您不需要检查所有

Deployment

来进行更新

如果您想使用

pykube

进行更新，下面是一个实际示例

import pykube
import operator

api = pykube.HTTPClient(pykube.KubeConfig.from_file("~/.kube/config"))

name = "ms-999-ear2-071625"
deployment_obj = {
          "apiVersion": "extensions/v1beta1",
          "kind": "Deployment",
          "metadata": {
              "name": name,
          }
      }

deployment = pykube.Deployment(api, deployment_obj)
deployment.update()
deployment.replicas = 2
deployment.update()

---

以下方法更简单：

import pykube
import operator

api = pykube.HTTPClient(pykube.KubeConfig.from_file("/root/.kube/config"))

deployment = pykube.Deployment.objects(api).filter(namespace="kube-system").get(name="test-busybox")

deployment.replicas = 1
deployment.update()
