1.安装Docker

1.1 安装必要的一些系统工具

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

1.2 添加软件源信息

sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

1.3 更新并安装

sudo yum makecache fast
sudo yum -y install docker-ce

1.4 开启Docker服务

sudo service docker start

1.5 启动docker

systemctl enable docker
systemctl start docker

1.6 设置阿里云镜像加速

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{"registry-mirrors": ["https://u4svfmjb.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

2.安装docker-compose

Harbor是通过docker-compose来管理镜像的，所以在Harbor主机安装docker-compose是必须的首要的一步。

curl -L "https://github.com/docker/compose/releases/download/1.25.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
或
curl -L https://dn-dao-github-mirror.daocloud.io/docker/compose/releases/download/1.25.4/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-composechmod +x /usr/local/bin/docker-compose
ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
docker-compose --version[root@edge-01 opt]# docker-compose --version
docker-compose version 1.25.4, build 8d51620a
[root@edge-01 opt]#

3.安装Harbor1.10.1

3.1 Harbor的域名

如果没有域名的话，可以自己定义一个域名，并在Harbor主机和Docker主机通过向/etc/hosts文件添加条目完成自定义域名与Harbor主机IP的映射关系。本文中自定义的域名是harbor.cn，配置如下：

[root@edge-01 opt]# more /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6#### harbor server ############
10.20.73.69  harbor.cn
[root@edge-01 opt]#

3.2 生成自签证书

Docker默认通过HTTPS与Harbor通信的，虽然可以改为HTTP方式，但需要修改的配置项会很多，而且也不安全。

有了域名了，配套的CA证书自然是少不了的。

mkdir -p /home/k8s/cert_harbor
cd /home/k8s/cert_harbor

3.2.1 生成根证书私钥（无加密）

openssl genrsa -out ca.key 4096

3.2.2 生成自签名证书（使用已有私钥ca.key自行签发根证书）生成ca.crt

openssl req -x509 -new -nodes -sha512 -days 3650 \-subj "/C=CN/ST=Beijing/L=Beijing/O=ccx/OU=plat/CN=10.20.73.69" \-key ca.key \-out ca.crt
#添加-subj参数可以免去交互过程

3.2.3 生成服务器端自己域名的key

openssl genrsa -out harbor.cn.key 4096

3.2.4 生成服务器端自己域名的CSR签名请求

openssl req -sha512 -new \-subj "/C=CN/ST=Beijing/L=Beijing/O=ccx/OU=plat/CN=10.20.73.69" \-key harbor.cn.key \-out harbor.cn.csr

3.2.5 生成一个 openssl 命令需要的外部配置文件 externalfile.ext

文件内容中主要是subjectAltName这一项

如果配IP就写IP.1=10.20.xxx.xxx

如果配域名就写 DNS.1=xxx.cn

vim externalfile.ext

authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
extendedKeyUsage = serverAuth 
subjectAltName = @alt_names
[alt_names]
DNS.1=harbor.cn

3.2.6 通过外部配置文件 externalfile.ext和 csr 生成 crt

openssl x509 -req -sha512 -days 3650 -extfile externalfile.ext \-CA ca.crt \-CAkey ca.key \-CAcreateserial \-in harbor.cn.csr \-out harbor.cn.crt

3.2.7 将服务端的 crt 转换成客户端用的 cert

openssl x509 -inform PEM -in harbor.cn.crt -out harbor.cn.cert[root@edge-01 cert_harbor]# ll
总用量 32
-rw-r--r--. 1 root root 2004 3月  17 14:22 ca.crt
-rw-r--r--. 1 root root 3243 3月  17 14:21 ca.key
-rw-r--r--. 1 root root   17 3月  17 14:41 ca.srl
-rw-r--r--. 1 root root  228 3月  17 14:41 externalfile.ext
-rw-r--r--. 1 root root 2033 3月  17 14:42 harbor.cn.cert
-rw-r--r--. 1 root root 2033 3月  17 14:41 harbor.cn.crt
-rw-r--r--. 1 root root 1691 3月  17 14:26 harbor.cn.csr
-rw-r--r--. 1 root root 3243 3月  17 14:24 harbor.cn.key
[root@edge-01 cert_harbor]#

3.3 为各个docker客户端分发证书

将Harbor主机上带域名的.cert和.key证书文件拷贝到docker客户端所在主机的/etc/docker/certs.d/xxx.xxx.com/目录下。下面以10.20.73.73这台docker客户端主机上的操作为例进行介绍。

3.3.1 在Docker主机上执行

 mkdir -p /etc/docker/certs.d/harbor.cn/

3.3.2 在Harbor主机执行

scp ./harbor.cn.cert ./harbor.cn.key root@10.20.73.73:/etc/docker/certs.d/harbor.cn/

3.3.3 在Docker主机修改 /etc/docker/daemon.json

主要是增加"insecure-registries":["http://harbor.cn"]

vim /etc/docker/daemon.json

{"registry-mirrors": ["https://u4svfmjb.mirror.aliyuncs.com"],"insecure-registries":["http://harbor.cn"]
}

3.3.4 重启Docker

systemctl daemon-reload
systemctl restart docker

3.4 下载&解压Harbor

cd /opt
wget https://github.com/goharbor/harbor/releases/download/v1.10.1/harbor-offline-installer-v1.10.1.tgz
mkdir -p /home/k8s/harbor

-rwxr-xr-x. 1 root root      1749 2月  10 14:18 prepare
[root@edge-01 harbor]#

3.5 修改配置文件harbor.yml

hostname: 10.20.73.69 #IP地址或域名
http:port: 80
https:port: 443certificate: /home/k8s/cert_harbor/harbor.cn.crt # 这里是证书信息private_key: /home/k8s/cert_harbor/harbor.cn.key # 这里是证书信息
harbor_admin_password: Harbor12345#  根据需要修改Web端admin用户的密码，默认为Harbor12345
database:password: Harbor12345 #  为harbor内置数据库root用户的密码，默认为root123
data_volumn: /data
log:level: infolocation: /var/log/harbor # harbor日志存放路径

3.5.1 更新参数

当你看到Harbor has been installed and started successfully时，我要恭喜你安装成功了

4.使用Harbor

4.1 访问Harbor WebUI

使用浏览器，通过https://域名或https://ip:port两种方式都可以访问Harbor的WebUI。因为是自签CA证书，浏览器会拦截，需要添加信任即可。

https://10.20.73.69/harbor/sign-in?redirect_url=%2Fharbor%2Fprojects

用户名：admin

密码：即harbor.yml文件中harbor_admin_password参数的值。默认是:Harbor12345

4.2 push镜像：docker ==> harbor

要想将镜像push到Harbor仓库中，必须先要在Harbor中创建自己的项目，即project，当然也可以使用Harbor自带的项目：library

下面看看如何做才能吧nginx镜像推送到Harbor镜像中去。

4.2.1 docker拉取一个镜像并修改tag

docker pull nginx
docker tag nginx:latest harbor.cn/library/nginx:latest

4.2.2 docker login 登录Harbor

# harbor_user_name - Harbor用户名
# harbor_password - 该Harbor用户的密码
# harbor_domain - Harbor的域名
docker login -u<harbor_user_name> -p<harbor_password> <harbor_domain>#执行命令，及输出
[root@edge-01 harbor]# docker login -uadmin -pHarbor12345 harbor.cn
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
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-storeLogin Succeeded
[root@edge-01 harbor]#

查看docker中保存的登录信息

[root@edge-01 harbor]# cat ~/.docker/config.json 
{"auths": {"harbor.cn": {"auth": "YWRtaW46SGFyYm9yMTIzNDU="}},"HttpHeaders": {"User-Agent": "Docker-Client/19.03.7 (linux)"}
}[root@edge-01 harbor]#

4.2.3 docker推送镜像到Harbor

# harbor_domain - Harbor的域名
# project_name - Harbor中的项目名称
# image_name - 镜像名称
# image_tag - 镜像tag
docker push <harbor_domain>/<project_name>/<image_name>:<image_tag>#执行命令，及输出
[root@edge-01 harbor]# docker push harbor.cn/library/nginx:latest
The push refers to repository [harbor.cn/library/nginx]
55a77731ed26: Pushed 
71f2244bc14d: Pushed 
f2cb0ecef392: Pushed 
latest: digest: sha256:3936fb3946790d711a68c58be93628e43cbca72439079e16d154b5db216b58da size: 948
[root@edge-01 harbor]#

4.2.4 登录Harbor查看镜像

4.3 pull镜像： docker <== harbor

Docker想从Harbor拉取镜像，只需要：

docker login 登录harbor
docker pull时，在镜像名称前加上Harbor的域名，就像这样：

docker login -uadmin -pHarbor12345 harbor.cn
docker pull harbor.cn/library/nginx:latest

4.4 重启harbor

docker-compose down
./prepare
docker-compose up -d
