docker registry使用用户名密码登录并解决docker login 400 Bad Request错误问题

创建存储凭据的文件夹：

1	`mkdir -p /root/auth`

现在，我将在Docker容器的帮助下创建htpasswd文件。该htpasswd文件将包含我的凭据和加密的passwd。

1	`docker run --entrypoint htpasswd registry -Bbn myuser mypassword > auth/htpasswd`

核实：

1 2	`cat auth/htpasswd` `myuser:$2y$05$8IpPEG94/u.gX4Hn9zDU3.6vru2rHJSehPEZfD1yyxHu.ABc2QhSa`

凭据很好。现在，我必须将我的凭据添加到注册表中。在这里，我将在容器中安装auth目录：

docker run  -d -p 5000:5000 --restart=unless-stopped --name registry-auth \
  -v  /root/auth:/auth \
  -v /data/registry:/var/lib/registry \
  -e "REGISTRY_AUTH=htpasswd" \
  -e  "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \
  -e  REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd \
  registry

测试：

docker push localhost:5000/busybox
The push refers to a repository [localhost:5000/busybox]
8ac8bfaff55a: Image push failed
unauthorized: authentication required

认证：

docker login localhost:5000
Username (): myuser
Password:
Login Succeeded

注意：因为服务器docker版本问题第一次docker login报错，Error response from daemon: login attempt to http://192.168.122.190:5000/v2/ failed with status: 400 Bad Request，升级了一下docker版本再docker login就成功了。

重试推送：

docker push localhost:5000/busybox
The push refers to a repository [localhost:5000/busybox]
8ac8bfaff55a: Pushed
latest: digest: sha256:1359608115b94599e5641638bac5aef1ddfaa79bb96057ebf41ebc8d33acf8a7 size: 527b

部署支持https的registry

1.安装docker（安装指定版本的话可以参考其他文档）
# docker install docker
2.拉取仓库镜像
# docker pull registry
3.生成认证certificate
# mkdir ~/certs
# openssl req -newkey rsa:4096 -nodes -sha256 -keyout /root/certs/domain.key  -x509 -days 365 -out /root/certs/domain.crt
4.复制认证到docker
# mkdir -p /etc/docker/certs.d/zmcheng.com:5000
# cp /root/certs/domain.crt  /etc/docker/certs.d/zmcheng.com:5000/ca.crt
5.复制认证到本机
# cat /root/certs/domain.crt >> /etc/pki/tls/certs/ca-bundle.crt 
7.启动仓库镜像
# docker run -d -p 5000:5000 --privileged=true -v /opt/docker-registry:/var/lib/registry -v /root/certs/:/root/certs  -e REGISTRY_HTTP_TLS_CERTIFICATE=/root/cer
ts/domain.crt -e REGISTRY_HTTP_TLS_KEY=/root/certs/domain.key registry
8.创建一个镜像
docker run -it --name=nginx centos /bin/bash
yum install epel-release.noarch -y
yum install nginx -y
docker commit 7ab4d6b6a438 dingyingsi/nginx  //7ab4d6b6a438为容器id
docker tag dingyingsi/nginx zmcheng.com:5000/nginx:latest //给当前镜像打标签
9.修改当前主机名：
vi /etc/hosts
10.20.31.166 zmcheng.com
10.推送镜像到https私有仓库
docker push zmcheng.com:5000/nginx
11.删除本地镜像并重新从https私有仓库拉取镜像
docker rmi zmcheng.com:5000/nginx
docker pull zmcheng.com:5000/nginx
 12.添加http basic authentication
docker run --entrypoint htpasswd  registry -Bbn root zmcheng2018 > /root/auth/htpasswd
13.停止仓库并删除容器
docker stop  726ae7846612
docker rm  ba29cdf804f07167707eeb871c7d0ee8cc6eab7c82f07f829b2bc91263941627
14.启动http basic authentication仓库
docker run -d \
--name registry \
-p 5000:5000 \
--restart=always \
--privileged=true \
-v /opt/docker-registry:/var/lib/registry \
-e "REGISTRY_AUTH=htpasswd" \
-e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \
-v /root/auth:/root/auth \
-e "REGISTRY_AUTH_HTPASSWD_PATH=/root/auth/htpasswd" \
-v /root/certs/:/root/certs \
-e REGISTRY_HTTP_TLS_CERTIFICATE=/root/certs/domain.crt \
-e REGISTRY_HTTP_TLS_KEY=/root/certs/domain.key \
registry
  
15.登录仓库
docker login zmcheng.com:5000
username:root
password:zmcheng2018
16.其他服务器用这个私有仓库，直接复制docker的仓库服务器下的/etc/docker/certs.d下的zmcheng.com:5000/ca.cert目录和文件，到自己的/etc/docker/cert.d/目录下即可。
