kubernetes - 使用 Ansibl 创建命名空间。导出命名空间=awx

Question

您好!

我厌倦了使用安装手册创建一些用于部署“AWX Operator”和 Kubernetes 的剧本 Install AWX Operator

我有命令:

export NAMESPACE=awx
kubectl create ns ${NAMESPACE}

我创建了任务:

- name: Echo export NAMESPACE awx
  shell: "export NAMESPACE=awx"
  environment:
    NAMESPACE: awx

- name: my_env_var 
  shell: "kubectl create ns NAMESPACE"

但是我得到一个错误:

fatal: [jitsi]: FAILED! => {"changed": true, "cmd": "kubectl create ns NAMESPACE", "delta": "0:00:00.957414", "end": "2021-10-22 13:25:16.822714", "msg": "non-zero return code", "rc": 1, "start": "2021-10-22 13:25:15.865300", "stderr": "The Namespace \"NAMESPACE\" is invalid: metadata.name: Invalid value: \"NAMESPACE\": a lowercase RFC 1123 label must consist of lower case alphanumeric characters or '-', and must start and end with an alphanumeric character (e.g. 'my-name',  or '123-abc', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?')", "stderr_lines": ["The Namespace \"NAMESPACE\" is invalid: metadata.name: Invalid value: \"NAMESPACE\": a lowercase RFC 1123 label must consist of lower case alphanumeric characters or '-', and must start and end with an alphanumeric character (e.g. 'my-name',  or '123-abc', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?')"], "stdout": "", "stdout_lines": []}

你能帮我提点建议吗？ 谢谢。

你把所有的东西都写在了这个错误中:)

命令有问题

kubectl create ns NAMESPACE

您想创建一个名为 NAMESPACE 的 namespace ，这是错误的。 您不能在命名空间的名称中使用大写字母。您可以从这条消息中得到提示:

Invalid value: \"NAMESPACE\": a lowercase RFC 1123 label must consist of lower case alphanumeric characters or '-', and must start and end with an alphanumeric character (e.g. 'my-name',  or '123-abc'

如何解决？您需要更改此行:

shell: "kubectl create ns NAMESPACE"

您需要正确设置没有大写字母的命名空间。

示例:

shell: "kubectl create ns my-namespace"

shell: "kubectl create ns my-name"

shell: "kubectl create ns whatever-you-want"
