Ansible: Kubectl snap安装失败

Question

下面是我从snap包管理器安装kubectl的过程

- name: Install the kubectl snap package
  snap:
    name: kubectl
    channel: "1.13/stable"
    classic: yes
    state: present

但是我得到了以下错误

> {"changed": false, "channel": "1:13/stable", "classic": true, "cmd":

这出戏按预期上演了。

- name: Install the kubectl snap package
  snap:
    name: kubectl
    channel: "1.13/stable"
    classic: yes
    state: present

$ kubectl version
Client Version: version.Info{Major:"1", Minor:"13", GitVersion:"v1.13.12", GitCommit:"a8b52209ee172232b6db7a6e0ce2adc77458829f", GitTreeState:"clean", BuildDate:"2019-10-17T19:01:20Z", GoVersion:"go1.12.10", Compiler:"gc", Platform:"linux/amd64"}

您的错误消息说明安装kubectl的1:13/stable版本失败。

Ooops! Snap installation failed while executing 'sh -c \"/usr/bin/snap install --classic --channel 1:13/stable kubectl\"', please examine logs and error output for more details.

可能是您在执行攻略时键入了错误的频道版本。通道必须是列出的here通道之一。
