一、安装 buildkit 客户端
buildkit 可执行文件: 下载地址
解压：
tar -zxvf buildkit-v0.10.6.linux-amd64.tar.gz
复制到 /usr/bin
cp build/buildctl /usr/bin/
二、验证安装
buildkit -version
- 可以看到已经安装成功了
三、安装buildkitd 服务
- 复制
buildkitd到/usr/bin
cp build/builkitd /usr/bin/
- 配置 systemd 服务
创建/usr/lib/systemd/system/buildkitd.service文件：
cat > /usr/lib/systemd/system/buildkitd.service <<EOF [Unit] Description=/usr/bin/buildkitd ConditionPathExists=/usr/bin/buildkitd After=containerd.service [Service] Type=simple ExecStart=/usr/bin/buildkitd User=root Restart=on-failure RestartSec=1500ms [Install] WantedBy=multi-user.target EOF
- 开机自启动
systemctl daemon-reload && systemctl restart buildkitd && systemctl enable buildkitd
验证运行状态
systemctl status buildkitd
四、构建镜像
未运行 buildkitd 之前：会报下面的错误：
[root@k8s0 cbbpa-server-utils]# nerdctl build -t test/testimage:0.0.1 . ERRO[0000] `buildctl` needs to be installed and `buildkitd` needs to be running, see https://github.com/moby/buildkit error="2 errors occurred:\n\t* failed to ping to host unix:///run/buildkit-default/buildkitd.sock: exit status 1\n\t* failed to ping to host unix:///run/buildkit/buildkitd.sock: exit status 1\n\n" FATA[0000] no buildkit host is available, tried 2 candidates: 2 errors occurred: * failed to ping to host unix:///run/buildkit-default/buildkitd.sock: exit status 1 * failed to ping to host unix:///run/buildkit/buildkitd.sock: exit status 1
运行 buildkitd 执行：就跑通了：
