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?的pouch等，为了保证容器?态的标准性和健康可持续发展，包括Linux 基?会、Docker、微软、红帽、?歌和IBM等公司在2015年6?共同成?了?个叫open container（OCI）的组织，其?的就是制定开放的标准的容器规范，?前OCI?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?个镜像构建?具包，?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)，?前?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?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.

如果你给harbor添加的有service文件，也可以使用systemctl stop/start harbor来停止/启动harbor

验证harbor是否可以正常登录？

4.2、nginx实现harbor的反向代理

4.2.1、nginx安装及配置

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?录，并生成私钥，证书

4.2.1.1、创建证书?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

root@k8s-deploy:/apps/nginx/certs# cat /apps/nginx/conf/nginx.conf
worker_processes  1;
events {
    worker_connections  1024;
}
http {

root@k8s-deploy:/apps/nginx#

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?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?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?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
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: 
WARN[0005] skipping verifying HTTPS certs for "harbor.magedu.net" 
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-store

Login Succeeded
root@k8s-master01:~# nerdctl login --insecure-registry https://harbor.magedu.net 
WARN[0000] skipping verifying HTTPS certs for "harbor.magedu.net" 
WARNING: Your password will be stored unencrypted in /root/.docker/config.json.

Login Succeeded
root@k8s-master01:~#

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?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/
ca.crt                                                                                                               100% 2041     1.5MB/s   00:00    
magedu.net.cert                                                                                                      100% 1915     1.6MB/s   00:00    
magedu.net.key                                                                                                       100% 3272     2.9MB/s   00:00    
root@k8s-deploy:/apps/nginx/certs#

5.2.4、镜像构建服务器上验证证书

root@k8s-master01:~# cd /etc/containerd/certs.d/harbor.magedu.net
root@k8s-master01:/etc/containerd/certs.d/harbor.magedu.net# ll
total 20
drwxr-xr-x 2 root root 4096 May 31 17:49 ./
drwxr-xr-x 3 root root 4096 May 31 17:44 ../
-rw-r--r-- 1 root root 2041 May 31 17:49 ca.crt
-rw-r--r-- 1 root root 1915 May 31 17:49 magedu.net.cert
-rw------- 1 root root 3272 May 31 17:49 magedu.net.key
root@k8s-master01:/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
Enter Password: 
WARN[0005] skipping verifying HTTPS certs for "harbor.magedu.net" 
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-store

Login Succeeded

/usr/local/bin/nerdctl push harbor.magedu.net/magedu/nginx-base:1.22.0
root@k8s-master01:~/ubuntu#

5.4、通过脚本?动构建并把镜像上传到镜像仓库

root@k8s-master01:~/ubuntu# bash build-command.sh

5.5、验证镜像是否上传到harbor仓库？


6、基于?定义镜像创建测试容器

6.1、nerdctl命令

root@k8s-node01:~# nerdctl run -d -p 80:80 harbor.magedu.net/magedu/nginx-base:1.22.0
