Microk8s ImagePullBackOff 无法通过修改配置修复

编程问答 2022-05-18

问题描述

我已经在 ubuntu（arm64 位版本）上安装了 microk8s，我想访问 microk8s enable registry 提供的本地镜像注册表。但是我收到 ImagePullBackOff 错误，我尝试修改 /var/snap/microk8s/current/args/containerd.toml 配置，但它不起作用：

[plugins.cri.registry]
  [plugins.cri.registry.mirrors]
    [plugins.cri.registry.mirrors."docker.io"]
      endpoint = ["https://registry-1.docker.io"]
    [plugins.cri.registry.mirrors."localhost:32000"]
      endpoint = ["http://localhost:32000"]
    [plugins.cri.registry.mirrors."192.168.0.45:32000"]
      endpoint = ["http://192.168.0.45:32000"]
    [plugins.cri.registry.configs."192.168.0.45:32000".tls]
      insecure_skip_verify = true

好像是想用https代替http。

如何在带有 containerd 的 microk8s 中使用不安全选项？
