#解压containerd到根目录
tar zxvf cri-containerd-cni-1.6.0-linux-amd64.tar.gz -C /
#生成containerd配置
mkdir -p /etc/containerd
containerd config default > /etc/containerd/config.toml
#启动containerd
systemctl daemon-reload
systemctl enable containerd
systemctl start containerd
systemctl status containerd
#把cni命令ln到/usr/local/bin目录下

四、测试
mkdir test
cd test
cat > Dockerfile << 'EOF'
FROM alpine
EOF

测试动行时
docker run -d -p 80:80 nginx
iptables -t nat -nvL
五、配置私有仓库
vim /etc/containerd/config.toml
[plugins."io.containerd.grpc.v1.cri".registry]
config_path = ""
<span class="token punctuation">[</span>plugins.<span class="token string">"io.containerd.grpc.v1.cri"</span>.registry.auths<span class="token punctuation">]</span>

key_file <span class="token operator">=</span> <span class="token string">"/home/data/cert/harbor-key.pem"</span>
六、nerdctl 使用http 的harbor
nerdctl login harbor.cadp.com --insecure-registry -u admin -p Harbor123456
WARN[0000] WARNING! Using --password via the CLI is insecure. Use --password-stdin.
WARN[0000] skipping verifying HTTPS certs for "harbor.cadp.com"
WARNING: Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See

#拉取镜像
docker pull harbor.cadp.com/smartgate/gwit:v5 --insecure-registry
#这个为ctr 下载镜像命令
ctr -n k8s.io i pull --plain-http harbor.cadp.com/smartgate/gwit:v5
# --plain-http 表示使用http下载
#推送镜像
docker push harbor.cadp.com/public/elasticsearch:7.13.1 --insecure-registry
