基于nerdctl+buildkitd+containerd实现镜像构建
1、容器技术简介
容器技术除了的docker之外，还有coreOS的rkt、google的gvisor、以及docker开源的containerd、redhat的podman、阿⾥的pouch等，为了保证容器⽣态的标准性和健康可持续发展，包括Linux 基⾦会、Docker、微软、红帽、⾕歌和IBM等公司在2015年6⽉共同成⽴了⼀个叫open container（OCI）的组织，其⽬的就是制定开放的标准的容器规范，⽬前OCI⼀共发布了两个规范，分别是runtime spec和image format spec，有了这两个规范，不同的容器公司开发的容器只要兼容这两个规范，就可以保证容器的可移植性和相互可操作性。
containerd官网：https://containerd.io/
gvisor官网：https://gvisor.dev/
podman官网：https://podman.io
pouch项目地址：https://github.com/alibaba/pouch
buildkit: 从Docker公司的开源出来的⼀个镜像构建⼯具包，⽀持OCI标准的镜像构建,项目地址https://github.com/moby/buildkit
2、buildkitd组成部分
buildkitd(服务端)，⽬前⽀持runc和containerd作为镜像构建环境，默认是runc，可以更换为containerd。
buildctl(客户端)，负责解析Dockerfile⽂件，并向服务端buildkitd发出构建请求。
3、部署buildkitd
3.1、下载二进制包
wget https://github.com/moby/buildkit/releases/download/v0.11.6/buildkit-v0.11.6.linux-amd64.tar.gz
解压压缩包，将二进制文件软连接至path环境变量
root@k8s-master01:/usr/local/src# ls
buildkit-v0.11.6.linux-amd64.tar.gz
root@k8s-master01:/usr/local/src# tar xf buildkit-v0.11.6.linux-amd64.tar.gz
root@k8s-master01:/usr/local/src# ls
bin buildkit-v0.11.6.linux-amd64.tar.gz
root@k8s-master01:/usr/local/src# cd bin
root@k8s-master01:/usr/local/src/bin# ls
buildctl buildkit-qemu-arm buildkit-qemu-mips64 buildkit-qemu-ppc64le buildkit-qemu-s390x buildkitd
buildkit-qemu-aarch64 buildkit-qemu-i386 buildkit-qemu-mips64el buildkit-qemu-riscv64 buildkit-runc
root@k8s-master01:/usr/local/src/bin# ln -s /usr/local/src/bin/* /usr/local/bin/
root@k8s-master01:/usr/local/src/bin# buildctl --help
NAME:
buildctl - build utility
USAGE:
buildctl [global options] command [command options] [arguments...]
VERSION:
v0.11.6
COMMANDS:
du disk usage
prune clean up build cache
build, b build
debug debug utilities
help, h Shows a list of commands or help for one command
GLOBAL OPTIONS:
--debug enable debug output in logs
--addr value buildkitd address (default: "unix:///run/buildkit/buildkitd.sock")
--tlsservername value buildkitd server name for certificate validation
--tlscacert value CA certificate for validation
--tlscert value client certificate
--tlskey value client key
--tlsdir value directory containing CA certificate, client certificate, and client key
--timeout value timeout backend connection after value seconds (default: 5)
--help, -h show help
--version, -v print the version
root@k8s-master01:/usr/local/src/bin#
能够正常在bash中执行buildkit --help ，表示对应命令已经正常软连接至path环境中。
3.2、提供buildkit.socket文件
root@k8s-master01:/usr/local/src/bin# cat /lib/systemd/system/buildkit.socket
[Unit]
Description=BuildKit
Documentation=https://github.com/moby/buildkit
[Socket]
ListenStream=%t/buildkit/buildkitd.sock
[Install]
WantedBy=sockets.target
root@k8s-master01:/usr/local/src/bin#
3.3、提供buildkit.service文件
root@k8s-master01:/usr/local/src/bin# cat /lib/systemd/system/buildkitd.service
[Unit]
Description=BuildKit
Requires=buildkit.socket
After=buildkit.socketDocumentation=https://github.com/moby/buildkit
[Service]
ExecStart=/usr/local/bin/buildkitd --oci-worker=false --containerd-worker=true
[Install]
WantedBy=multi-user.target
root@k8s-master01:/usr/local/src/bin#
3.4、启动buildiktd服务
root@k8s-master01:/usr/local/src/bin# systemctl daemon-reload
root@k8s-master01:/usr/local/src/bin# systemctl enable buildkitd
Created symlink /etc/systemd/system/multi-user.target.wants/buildkitd.service → /lib/systemd/system/buildkitd.service.
root@k8s-master01:/usr/local/src/bin# systemctl restart buildkitd
root@k8s-master01:/usr/local/src/bin# systemctl status buildkitd

上述报错没有找到http模块依赖的PCRE库
解决办法：安装libpcre3 libpcre3-dev
root@k8s-deploy:/usr/local/src/nginx-1.22.0# apt install libpcre3 libpcre3-dev -y
安装上述依赖后，重新configure
上述报错没有找到ssl模块依赖的openssl库
解决办法：安装openssl libssl-dev
root@k8s-deploy:/usr/local/src/nginx-1.22.0# apt install openssl libssl-dev -y
执行上述./configure 没有报错，并且能够看到上述截图，表示编译环境通过检查，可以进行下一步编译和安装
编译安装nginx
root@k8s-deploy:/usr/local/src/nginx-1.22.0# make && make install
创建证书⽬录，并生成私钥，证书
4.2.1.1、创建证书⽬录,并生成ca私钥
root@k8s-deploy:/apps/nginx/sbin# mkdir /apps/nginx/certs
root@k8s-deploy:/apps/nginx/sbin# cd /apps/nginx/certs
root@k8s-deploy:/apps/nginx/certs# openssl genrsa -out ca.key 4096
4.2.1.2、用ca私钥生成ca自签名证书
root@k8s-deploy:/apps/nginx/certs# openssl req -x509 -new -nodes -sha512 -days 3650 \
> -subj "/C=CN/ST=Beijing/L=Beijing/O=Personal-CA/OU=Personal/CN=CA.com" \
> -key ca.key \
> -out ca.crt
root@k8s-deploy:/apps/nginx/certs# ls
ca.crt ca.key
root@k8s-deploy:/apps/nginx/certs#
4.2.1.3、生成harbor服务器私钥
root@k8s-deploy:/apps/nginx/certs# openssl genrsa -out magedu.net.key 4096
root@k8s-deploy:/apps/nginx/certs# ls
ca.crt ca.key magedu.net.key
root@k8s-deploy:/apps/nginx/certs#
4.2.1.4、用harbor服务器私钥生成生成证书签名请求csr文件
root@k8s-deploy:/apps/nginx/certs# openssl req -sha512 -new \
> -subj "/C=CN/ST=Beijing/L=Beijing/O=test/OU=Personal/CN=magedu.net" \
> -key magedu.net.key \
> -out magedu.net.csr
root@k8s-deploy:/apps/nginx/certs# ls
ca.crt ca.key magedu.net.csr magedu.net.key
root@k8s-deploy:/apps/nginx/certs#
4.2.1.5、使用ca证书和私钥为harbor服务器签发证书
root@k8s-deploy:/apps/nginx/certs# openssl x509 -req -sha512 -days 3650 \
> -CA ca.crt -CAkey ca.key -CAcreateserial \
> -in magedu.net.csr \
> -out magedu.net.crt
Certificate request self-signature ok
subject=C = CN, ST = Beijing, L = Beijing, O = test, OU = Personal, CN = magedu.net
root@k8s-deploy:/apps/nginx/certs# ls
ca.crt ca.key magedu.net.crt magedu.net.csr magedu.net.key
root@k8s-deploy:/apps/nginx/certs#
编辑nginx配置文件，配置证书和反向代理harbor

4.2.2、浏览器访问测试nginx 看看是否反向代理给harbor？是否为https？
查看证书信息
4.2.3、buildkitd配置⽂件
root@k8s-master01:/usr/local/src/bin# cat /etc/buildkit/buildkitd.toml
[registry."harbor.magedu.net"]
http = true
insecure = true
root@k8s-master01:
4.2.4、nerdctl配置⽂件
root@k8s-master01:/usr/local/src/bin# cat /etc/nerdctl/nerdctl.toml
namespace = "k8s.io"
debug = false
debug_full = false
insecure_registry = true
root@k8s-master01:/usr/local/src/bin#
5、测试镜像构建
5.1、nerdctl常⽤命令
5.1.1 给nerdctl添加命令补全
root@k8s-master01:~# echo "source <(nerdctl completion bash)" >> /etc/profile
root@k8s-master01:~# cat /etc/profile
# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).
if [ "${PS1-}" ]; then
if [ "${BASH-}" ] && [ "$BASH" != "/bin/sh" ]; then
# The file bash.bashrc already sets the default PS1.
# PS1='\h:\w\$ '
if [ -f /etc/bash.bashrc ]; then
. /etc/bash.bashrc
fi
else
if [ "$(id -u)" -eq 0 ]; then
PS1='# '
else
PS1='$ '
fi
fi

if [ -d /etc/profile.d ]; then
for i in /etc/profile.d/*.sh; do
if [ -r $i ]; then
. $i
fi
done
unset i
fi
source <(nerdctl completion bash)
root@k8s-master01:~# source /etc/profile
5.1.2、登录harbor仓库
root@k8s-master01:~# nerdctl login harbor.magedu.net
Enter Username: admin
Enter Password:

自签名证书一般通过--insecure-registry 选项来指定该仓库是一个不安全的仓库
5.2、自签名harbor证书分发
5.2.1、创建证书⽬录
root@k8s-master01:~# mkdir -pv /etc/containerd/certs.d/harbor.magedu.net
mkdir: created directory '/etc/containerd/certs.d'
mkdir: created directory '/etc/containerd/certs.d/harbor.magedu.net'
root@k8s-master01:~#
5.2.2、证书格式转换
root@k8s-deploy:~# cd /apps/nginx/certs/
root@k8s-deploy:/apps/nginx/certs# openssl x509 -inform PEM -in magedu.net.crt -out magedu.net.cert
root@k8s-deploy:/apps/nginx/certs#
5.2.3、开始分发证书至镜像构建服务器
root@k8s-deploy:/apps/nginx/certs# scp ca.crt magedu.net.cert magedu.net.key 192.168.0.31:/etc/containerd/certs.d/harbor.magedu.net/

5.2.5、删除原有登录信息，重新登录harbor
root@k8s-master01:~# rm -rf .docker/config.json
root@k8s-master01:~# nerdctl login harbor.magedu.net
Enter Username: admin
