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
REPOSITORY                          TAG       IMAGE ID        CREATED          PLATFORM       SIZE        BLOB SIZE
192.168.199.102:80/library/nginx    alpine    c94a22b036af    6 minutes ago    linux/amd64    42.7 MiB    16.0 MiB
nginx                               alpine    c94a22b036af    7 minutes ago    linux/amd64    42.7 MiB    16.0 MiB

3.2 登录harbor

>nerdctl login 192.168.199.102:80
Enter Username: admin
Enter Password:
WARNING: Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-storeLogin Succeeded

3.3 上传镜像

上传到 harbor 仓库

>nerdctl push 192.168.199.102:80/library/nginx:alpine
INFO[0000] pushing as a reduced-platform image (application/vnd.docker.distribution.manifest.list.v2+json, sha256:3d7805c209c8f28a172fc1b6adea4db8d68ca54d0e1696a655ef0c75333add45)

3.4 harbor仓库查看镜像

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 SIZE

3.6 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
REPOSITORY    TAG    IMAGE ID    CREATED    PLATFORM    SIZE    BLOB SIZE
>nerdctl run --name ngx -d -p 80:80 192.168.199.102:80/library/nginx:alpine

3.7 验证查看

>curl -I localhost
HTTP/1.1 200 OK
Server: nginx/1.23.4
Date: Thu, 06 Apr 2023 06:41:25 GMT
Content-Type: text/html
Content-Length: 615
Last-Modified: Tue, 28 Mar 2023 17:09:24 GMT
Connection: keep-alive
ETag: "64231f44-267"
Accept-Ranges: bytes

OK，nginx启动成功。

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
REPOSITORY    TAG                 IMAGE ID        CREATED           PLATFORM       SIZE         BLOB SIZE
busybox       stable              5acba83a746c    17 minutes ago    linux/amd64    1.2 MiB      758.9 KiB

mysql         latest              e9027fe4d91c    2 seconds ago     linux/amd64    504.6 MiB    144.4 MiB
nginx         alpine              eb05700fe7ba    23 minutes ago    linux/amd64    25.2 MiB     9.7 MiB
