Question

我正在尝试使用新的an k8s模块（基于2.6的ok k8_raw）来维护aks k8集群。虽然我可以使用kubectl使用集群，但是使用k8s集群的任何命令都会失败，并显示503错误。

例如，此任务：

- name: deploy kured daemonset
  k8s:
    state: present
    context: "{{ cluster_name}}"
    host: "redacted"# tried specifying this, but does not help
    kubeconfig: "~/.kube/config"
    src: "aks/utils/kured-ds.yaml"

失败：

可用的版本：2.7 / 8（dev）

我想念什么？

更新：当我将打印语句添加到下面的模块所使用的库中时，我发现在管道中的某处/ version / openshift附加到了主机名，这当然会失败，因为它是一个非openshift集群有没有解决此错误的方法？

Answer 1

答案：原来有两个失败的请求。首先是版本/ openshift被客户端捕获，不会导致崩溃。该崩溃实际上是由于我的集群指标服务器发生错误而发生的，尽管ansible使用的k8客户端并没有真正需要它，但仍然对该请求失败。因此，如果有人碰碰它，可能会有所帮助

ansible k8s模块无法使用503连接到集群-将/ version / openshift附加到非openshift集群
