docker 镜像仓库之私有云单机仓库Docker Registry

Docker 仓库分为公有云仓库和私有云仓库
  公有云仓库：由互联网公司对外公开的仓库
    官方
    阿里云等第三方仓库
  私有云仓库：组织内部搭建的仓库，一般只为组织内部使用，常使用下面软件搭建仓库
    docker registory
    docker harbor

私有云单机仓库Docker Registry配置说明



#安装httpd工具包
yum  -y  install httpd-tools

#创建目录保存用户信息以及数据
mkdir /docker/registry/ /docker/registry/auth  /dokcer/registry/data  -pv

#在registry下创建auth目录，用于存放用于registry容器的用户名密码的文件,用户名密码不是必须的，如果不设置，则部署的仓库默认为公共仓库。
#生成密码加密的内容
[root@localhost7C registry]# htpasswd -Bbn root 123456 > /docker/registry/auth/htpasswd
[root@localhost7C registry]# htpasswd -Bbn zzhz 123456 >>  /docker/registry/auth/htpasswd


# 以授权方式启动
docker run -d -p 5000:5000 --name registryA --restart=always --privileged=true \
-v /docker/registry/data:/var/lib/registry \
-v /docker/registry/auth:/auth \
-e "REGISTRY_AUTH=htpasswd" \
-e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \
-e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd docker.io/registry:latest

客户端http登录设置非安全模式登录
方法一、在daedom.json输入"insecure-registries":["192.168.80.120:5000"]
方法二、启动文件中设置
[root@localhost7B haproxy]# vim /lib/systemd/system/docker.service 
[Service]
Type=notify
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock  --insecure-registry 192.168.80.120:5000
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutSec=0
RestartSec=2
Restart=always


测试：登录
[root@localhost7B haproxy]# docker login 192.168.80.120:5000
Username: root
Password: 
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.

问题：使用https一直无法登录,提示一直输入密码。测试失败。

设置https方式
使用openssl自建域名证书，此处假设域名为registry.abc.com.并创建/docker/registry/certs目录用于专门存放证书文件
[root@localhost7B ]# yum -y install openssl openssl-devel

生成根证书，执行命令后依次要输入：国家代码（两个英文字母）、省份、城市、组织、单位、域名(www.abc.com)、邮箱。
[root@localhost7B ]# openssl req -newkey rsa:4096 -nodes -sha256 -keyout /docker/registry/certs/domain.key -x509 -days 3000 -out /docker/registry/certs/domain.crt

# 以授权方式启动,
docker run -d -p 5000:5000 -p 443:443 --name registryA --restart=always --privileged=true \
-v /docker/registry/certs:/certs \
-v /docker/registry/data:/var/lib/registry \
-v /docker/registry/auth:/auth \
-e REGISTRY_HTTP_ADDR=0.0.0.0:443 \
-e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt \
-e REGISTRY_HTTP_TLS_KEY=/certs/domain.key \
-e "REGISTRY_AUTH=htpasswd" \
-e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \
-e REGISTRY_AUTH_HTPASSWD_PATH=/var/lib/registry/auth/htpasswd docker.io/registry:latest

#注意下，进入到/etc/docker/certs.d/后，创建目录名同docker的仓库地址（我的是www.abc.com）
mkdir /etc/docker/certs.d/www.abc.com
cp domain.crt /etc/docker/certs.d/www.abc.com

#无BASIC认证账号使用https是可以的。
docker run -d -p 5000:5000 -p 443:443 --name registryA --restart=always --privileged=true \
-v /docker/registry/certs:/certs \
-v /docker/registry/data:/var/lib/registry \
-e REGISTRY_HTTP_ADDR=0.0.0.0:443 \
-e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt \
-e REGISTRY_HTTP_TLS_KEY=/certs/domain.key docker.io/registry:latest

客户端要做hosts解析。
