在使用容器时，避免不了会使用到私有仓库，一般都是采用 harbor 作为私有仓库，docker 对接 harbor 仓库非常简单，哪 containerd 如何对接 harbor 呢？
在内网使用 harbor 根据个人习惯，一般都是非 http 并且是通过IP 直接访问，如下：
harbor仓库地址为：http://192.168.199.102:80 ，containerd 如何上传或者下载镜像呢？
2.配置说明
2.1 生成配置文件
>mkdir -p /etc/containerd/ >containerd config default
> /etc/containerd/config.toml
2.2 修改配置
大概从144行开始 >vim +144 /etc/containerd/config.toml 144 [plugins."io.containerd.grpc.v1.cri".registry] 145 config_path = "/etc/containerd/certs.d" #修改该行的配置信息 ...
创建该目录
上面的目录+harbor仓库地址
>mkdir -p /etc/containerd/certs.d/192.168.199.102:80
编写 harbor 配置
>vim /etc/containerd/certs.d/192.168.199.102\:80/hosts.toml
server = "http://192.168.199.102:80"
[host."http://192.168.199.102:80"]capabilities = ["pull", "resolve", "push"]skip_verify = true重启服务
>systemctl restart containerd
3.验证上传下载
3.1 准备镜像
首先，从网络上下载一个镜像
>nerdctl pull nginx:alpine
>nerdctl images
REPOSITORY TAG IMAGE ID CREATED PLATFORM SIZE BLOB SIZE
nginx alpine c94a22b036af 2 seconds ago linux/amd64 42.7 MiB 16.0 MiB为该镜像打TAG
>nerdctl tag nginx:alpine 192.168.199.102:80/library/nginx:alpine
>nerdctl images

nginx alpine c94a22b036af 7 minutes ago linux/amd64 42.7 MiB 16.0 MiB3.2 登录harbor
>nerdctl login 192.168.199.102:80

上传到 harbor 仓库
>nerdctl push 192.168.199.102:80/library/nginx:alpine

3.5 删除本地镜像
>nerdctl rmi 192.168.199.102:80/library/nginx:alpine nginx:alpine
>nerdctl images
REPOSITORY TAG IMAGE ID CREATED PLATFORM SIZE BLOB SIZE3.6 启动容器
目前本地是没有镜像的，直接通过 nerdctl run 启动容器。当本地没有镜像时，会直接从 harbor 拉取镜像。
>nerdctl images

4.配置镜像加速
通过上面的配置，不难启发我们配置国内镜像加速的方式，例如为 docker.io 配置镜像加速
>mkdir -p /etc/containerd/docker.io
>vim /etc/containerd/docker.io/hosts.toml
server = "https://docker.io"
[host."https://xxx.mirror.aliyuncs.com"] #注册阿里云可查看个人加速源重启服务
>systemctl restart containerd测试拉取镜像
>nerdctl pull mysql
>nerdctl images
