在前面的学习中，我们可以知道，我们所使用上传的镜像全都是公共镜像，镜像如果是商业机密，只能供公司内部人员使用，怎么办，这个就涉及到我们私有仓库的搭建。
Ubantu docker学习笔记（八）私有仓库
在这一章的学习中，我们就用两台主机，分别作为服务器端和客户端，现在我们开始吧！

名称	IP地址
服务端	192.168.2.109
客户端	192.168.2.108

一、建立HTTPS链接

<registry.xinhua.com>可以替换
/opt/docker/registry/certs也地址可以进行修改

1.在仓库服务器上获取TLS证书

新建一个目录

sudo su
mkdir -p /opt/docker/registry/certs
cd /opt/docker/registry/certs
ls

1.1 生成证书颁发机构证书

生成 CA 证书私钥

openssl genrsa -out ca.key 4096

生成ca证书

openssl req -x509 -new -nodes -sha512 -days 3650 \
 -subj "/C=CN/ST=Beijing/L=Beijing/O=example/OU=Personal/CN=registry.xinhua.com" \
 -key ca.key \
 -out ca.crt

Ubantu docker学习笔记（八）私有仓库

1.2 生成服务器证书

生成私钥

openssl genrsa -out registry.xinhua.com.key 4096

生成证书签名请求（CSR）

openssl req -sha512 -new \
    -subj "/C=CN/ST=Beijing/L=Beijing/O=example/OU=Personal/CN=registry.xinhua.com" \
    -key registry.xinhua.com.key \
    -out registry.xinhua.com.csr

Ubantu docker学习笔记（八）私有仓库
生成 x509 v3 扩展文件

cat > v3.ext <<-EOF
authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
extendedKeyUsage = serverAuth
subjectAltName = @alt_names

[alt_names]
DNS.1=registry.xinhua.com
DNS.2=registry.xinhua
DNS.3=hostname
EOF

使用该文件为主机生成证书v3.ext

openssl x509 -req -sha512 -days 3650 \
    -extfile v3.ext \
    -CA ca.crt -CAkey ca.key -CAcreateserial \
    -in registry.xinhua.com.csr \
    -out registry.xinhua.com.crt

1.3 利用证书运行仓库容器

docker run -it -d --name registry-TLS -p 5000:5000 -v /opt/docker/registry/certs/:/certs -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/registry.xinhua.com.crt -e REGISTRY_HTTP_TLS_KEY=/certs/registry.xinhua.com.key registry:2

2.让私有仓库支持HTTPS

ip addr

Ubantu docker学习笔记（八）私有仓库
在仓库服务器和客户端配置域名解析

sudo gedit /etc/hosts


192.168.2.109 registry.xinhua.com
192.168.2.109 nginx.xinhua.com

Ubantu docker学习笔记（八）私有仓库
验证一下

ping registry.xinhua.com

Ubantu docker学习笔记（八）私有仓库

3.客户端端配置

在仓库服务器和客户端配置域名解析

sudo gedit /etc/hosts

<服务器ip>
192.168.2.109 registry.xinhua.com
192.168.2.109 nginx.xinhua.com

Ubantu docker学习笔记（八）私有仓库
验证一下

ping registry.xinhua.com

Ubantu docker学习笔记（八）私有仓库
客户端安装open-ssh server

apt-get install openssh-server

在客户端上创建存储证书的目录

mkdir -p /etc/docker/certs.d/registry.xinhua.com\:5000

将服务器上的所有证书/opt/docker/registry/certs(.cert .key .crt)通过scp拷贝到创建客户端存储证书的目录服务端执行

修改服务端权限：chmod 777 /opt/docker/registry/certs
修改客户机权限：chmod 777 /etc/docker/certs.d/registry.xinhua.com:5000

scp -r -p /etc/docker/certs.d/registry.xinhua.com:5000/register.xinhua.com.crt username@serverip: /opt/docker/registry/certs/register.xinhua.com.crt 

username<登录用户名你服务器的名字【就是你直接打开控制台的名字】>
serverip<客户端ip（ip addr查看）> 192.168.2.108

scp -r -p /opt/docker/registry/certs/registry.xinhua.com.crt root-u@192.168.2.108:/etc/docker/certs.d/registry.xinhua.com:5000/register.xinhua.com.crt

Ubantu docker学习笔记（八）私有仓库
客户端

下面我们就来演示吧

名称	IP地址
服务端	192.168.2.109
客户端	192.168.2.108

在客户端推送镜像
代码解释参考：Ubantu docker学习笔记（三）docker账号push及Dockerfile优化

docker tag busybox:latest registry.xinhua.com:5000/busybox:V1
docker push registry.xinhua.com:5000/busybox:V1

Ubantu docker学习笔记（八）私有仓库

curl -X GET https://registry.xinhua.com:5000/v2/_catalog -k

Ubantu docker学习笔记（八）私有仓库

二、基本身份验证

创建目录及用户密码文件

mkdir /opt/docker/registry/auth
docker run  --entrypoint htpasswd  httpd:2 -Bbn testuser testpassword > /opt/docker/registry/auth/htpasswd

这里注意testuser testpassword 就是我们后面登录的账号密码了

停止之前镜像（直接把所有关了）

docker stop $(docker ps -q) & docker rm $(docker ps -aq)

再次运行我们的服务镜像

docker run -d  \
-p 5000:5000   \
--restart=always  \
--name registry  \
-v /opt/docker/registry/auth:/auth  \
-e "REGISTRY_AUTH=htpasswd"  \
-e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm"  \
-e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd  \
-v /opt/docker/registry/certs:/certs   \
-e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/registry.xinhua.com.crt   \
-e REGISTRY_HTTP_TLS_KEY=/certs/registry.xinhua.com.key   registry:2

Ubantu docker学习笔记（八）私有仓库
去我们客户端进行镜像上传

docker push registry.xinhua.com:5000/busybox:V1

Ubantu docker学习笔记（八）私有仓库
可以看到我们上传不了，接着我们登录

docker login registry.xinhua.com:5000

账号：testuser
密码：testpassword
Ubantu docker学习笔记（八）私有仓库

我们再去上传我们的镜像

docker push registry.xinhua.com:5000/busybox:V1

三、对外隐藏仓库服务器

3.1 在服务器端

安装nginx

apt install nginx

为nginx创建SSL秘钥和证书到/etc/nginx/certs/目录下

mkdir -p /etc/nginx/certs/
cd /etc/nginx/certs/
ls

开始参考https的方式啦，也就是相当于把registry.xinhua.com全都替换成nginx.xinhua.com

生成ca证书私钥

openssl genrsa -out ca.key 4096

生成ca证书

openssl req -x509 -new -nodes -sha512 -days 3650 \
 -subj "/C=CN/ST=Beijing/L=Beijing/O=example/OU=Personal/CN=nginx.xinhua.com" \
 -key ca.key \
 -out ca.crt

生成服务器证书,私钥

openssl genrsa -out nginx.xinhua.com.key 4096

生成证书签名请求（CSR）

openssl req -sha512 -new \
    -subj "/C=CN/ST=Beijing/L=Beijing/O=example/OU=Personal/CN=nginx.xinhua.com" \
    -key nginx.xinhua.com.key \
    -out nginx.xinhua.com.csr

生成 x509 v3 扩展文件

cat > v3.ext <<-EOF
authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
extendedKeyUsage = serverAuth
subjectAltName = @alt_names

[alt_names]
DNS.1=nginx.xinhua.com
DNS.2=nginx.xinhua
DNS.3=hostname
EOF

使用该文件为主机生成证书v3.ext

openssl x509 -req -sha512 -days 3650 \
    -extfile v3.ext \
    -CA ca.crt -CAkey ca.key -CAcreateserial \
    -in nginx.xinhua.com.csr \
    -out nginx.xinhua.com.crt

Ubantu docker学习笔记（八）私有仓库
在客户端上创建存储证书的目录

mkdir -p /etc/docker/certs.d/nginx.xinhua.com\:443

将服务器上的所有证书/opt/docker/registry/certs(.cert .key .crt)通过scp拷贝到创建客户端存储证书的目录服务端执行

修改服务端权限：
chmod 777 /etc/nginx/certs/
修改客户机权限：
chmod 777 /etc/docker/certs.d/nginx.xinhua.com:443
chmod 777 /usr/local/share/ca-certificates

username<登录用户名你服务器的名字【就是你直接打开控制台的名字】>
serverip<客户端ip（ip addr查看）> 192.168.2.108

scp -r -p /etc/nginx/certs/nginx.xinhua.com.crt root-u@192.168.2.108:/etc/docker/certs.d/nginx.xinhua.com:443/nginx.xinhua.com.crt
scp -r -p /etc/nginx/certs/nginx.xinhua.com.crt root-u@192.168.2.108:/usr/local/share/ca-certificates/nginx.xinhua.com.crt

修改nginx配置/etc/nginx/nginx.conf让nginx的支持SSL的反向代理和身份验证

使用htpasswd去生成用户账号，设置密码

mkdir /etc/nginx/auth
cd /etc/nginx/auth
apt install apache2-utils
htpasswd -c htpasswd.txt user

输入你的密码

重启Nginx服务

sudo /etc/init.d/nginx restart

注意！！！
一定要打全
https://192.168.2.109:443
直接输入域名可能出现以下错误

没有打端口号
Ubantu docker学习笔记（八）私有仓库
没有用http连接

正确！！！

3.2 在客户端进行

配置

sudo vi /etc/docker/daemon.json

{  
   "registry-mirrors": ["https://8f6a79wk.mirror.aliyuncs.com"],
   "insecure-registries":["私库地址（可以域名也可以ip）"]
}



我的配置
{
   "registry-mirrors": ["https://8f6a79wk.mirror.aliyuncs.com"],
   "insecure-registries":["https://nginx.xinhua.com"]
}

如果不配置就会出现
Error response from daemon: Get "https://nginx.xinhua.com/v2/": x509: certificate signed by unknown authority

update-ca-certificates
systemctl daemon-reload
systemctl restart docker

第一种：
docker login https://192.168.2.109:443 -u user -p "123456"

第二种：
#设置环境变量
export PASSWORD=123456
#以环境变量的方式读入
echo "$PASSWORD" | docker login https://https://nginx.xinhua.com --username user --password-stdin

Ubantu docker学习笔记（八）私有仓库

我们再去上传我们的镜像

docker tag busybox:latest 192.168.2.109:443/busybox:V1
docker push 192.168.2.109:443/busybox:V1

四、仓库可视化

http:

docker run --name registry -d  -p 5000:5000 --restart=always  -v /opt/data/registry:/var/lib/registry registry


docker run -it -d -p 8080:8080 --name registry-web --link registry   \
-e REGISTRY_URL=http://192.168.2.109:5000/v2            \
-e REGISTRY_TRUST_ANY_SSL=true            \
-e REGISTRY_BASIC_AUTH="cm9vdDoxMjM0NTY"            \
-e REGISTRY_NAME=192.168.2.109:5000 hyper/docker-registry-web
