默认的registry-1.docker.io被限制次数，搞的好烦

k8s 1.24 之后默认是不支持docker的，用containerd做实验，拉取镜像多次失败及被限制

用ansible-playbook写了个脚本，批量替换

cat containerd_setup.yml
---
- hosts: u7
  become: true
  tasks:
    - name: Add mirror repositories to containerd config
      lineinfile:
        path: /etc/containerd/config.toml
        regexp: '^\s*endpoint\s*=\s*\["https://registry-1.docker.io"\]'
        line: '          endpoint = ["https://dockerproxy.com", "https://docker.m.daocloud.io", "https://docker.mirrors.sjtug.sjtu.edu.cn", "https://docker.nju.edu.cn", "http://hub-mirror.c.163.com"]'
        state: present

单机的就直接修改 /etc/containerd/config.toml

          endpoint = ["https://registry-1.docker.io", "https://mirror.baidubce.com", "https://docker.mirrors.sjtug.sjtu.edu.cn", "https://docker.nju.edu.cn", "http://hub-mirror.c.163.com"]
