四、部署harbor的https
在harbor 172.168.33.201上部署
#1、部署docker源 curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - sudo add-apt-repository \ "deb [arch=amd64] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu \ $(lsb_release -cs) \ stable" apt-get update #2、查看支持的docker版本 apt-cache madison docker-ce #3、安装19.03.15版的docker apt-get install docker-ce=5:19.03.15~3-0~ubuntu-focal docker-ce-cli=5:19.03.15~3-0~ubuntu-focal #4、下载docker-compose v1.24.1 wget https://github.com/docker/compose/releases/download/1.24.1/docker-compose-Linux-x86_64 chmod +x docker-compose-Linux-x86_64 mv docker-compose-Linux-x86_64 /usr/bin/docker-compose
2、下载harbor-offine-installer-v2.3.2.tgz,并解压
root@harbor:~# mkdir /apps root@harbor:~# cd /apps root@harbor:/apps# wget https://github.com/goharbor/harbor/releases/download/v2.3.2/harbor-offline-installer-v2.3.2.tgz root@harbor:/apps# tar -xf harbor-offline-installer-v2.3.2.tgz
3、创建证书
root@harbor:/apps# cd harbor/ root@harbor:/apps/harbor# mkdir certs root@harbor:/apps/harbor# cd certs root@harbor:/apps/harbor/certs# openssl genrsa -out harbor-ca.key 2048 root@harbor:/apps/harbor/certs# openssl req -x509 -new -nodes -key harbor-ca.key -subj "/CN=harbor.ywx.net" -days 3650 -out harbor-ca.crt #注意：/CN=harbor.ywx.net必须是我们用来访问harbor的域名
4、编辑harbor的配置文件
5、安装harbor
root@harbor:/apps/harbor# ./install.sh --help Note: Please set hostname and other necessary attributes in harbor.yml first. DO NOT use localhost or 127.0.0.1 for hostname, because Harbor needs to be accessed by external clients. Please set --with-notary if needs enable Notary in Harbor, and set ui_url_protocol/ssl_cert/ssl_cert_key in harbor.yml bacause notary must run under https. Please set --with-trivy if needs enable Trivy in Harbor #开启镜像扫描 Please set --with-chartmuseum if needs enable Chartmuseum in Harbor root@harbor:/apps/harbor# ./install.sh --with-trivy ...... ✔ ----Harbor has been installed and started successfully.----
6、将harbor的公钥拷贝到docker并测试
#1、在docker中创建存放公钥的目录 root@harbor:/etc/docker# mkdir -p certs.d/harbor.ywx.net #注意：存放公钥的目录必须为域名地址 #2、把harbor公钥拷贝到docker存放公钥的目录 root@harbor:/etc/docker# cp /apps/harbor/certs/harbor-ca.crt /etc/docker/certs.d/harbor.ywx.net/ root@harbor:/etc/docker/certs.d/harbor.ywx.net# ls harbor-ca.crt #3、使用docker登录harbor.ywx.net root@harbor:~# docker login harbor.ywx.net Username: admin 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-store Login Succeeded #4、拉取nginx镜像来测试 root@harbor:~# docker pull nginx #5、更改nginx镜像名称 root@harbor:~# docker tag nginx:latest harbor.ywx.net/k8s-baseimages/nginx:latest #6、上传镜像 root@harbor:~# docker push harbor.ywx.net/k8s-baseimages/nginx:v1 The push refers to repository [harbor.ywx.net/k8s-baseimages/nginx] fac15b2caa0c: Pushed f8bf5746ac5a: Pushed d11eedadbd34: Pushed 797e583d8c50: Pushed bf9ce92e8516: Pushed d000633a5681: Pushed v1: digest: sha256:6fe11397c34b973f3c957f0da22b09b7f11a4802e1db47aef54c29e2813cc125 size: 1570

在部署节点harbor 172.168.33.201
3.1下载项目源码、二进制及离线镜像
# 下载工具脚本ezdown，举例使用kubeasz版本3.0.0
export release=3.0.0
curl -C- -fLO --retry 3 https://github.com/easzlab/kubeasz/releases/download/${release}/ezdown
chmod +x ./ezdown
# 使用工具脚本下载
./ezdown -D
或者直接下载
wget https://github.com/easzlab/kubeasz/releases/download/3.1.0/ezdown
