手把手docker registry配置登录名/密码

我们的Docker私有仓库Registry服务只有加了认证机制之后我们的Registry服务才会更加的安全可靠。赶快跟随以下步骤来增加认证机制吧。

1. 创建docker registry工作目录

mkdir -p /data/docker.registry

2. 创建将保存凭据的文件夹

mkdir -p /data/docker.registry/etc/registry/auth

3. 安装htpasswd工具。

yum -y install httpd-tools

创建管理员admin，存入/data/docker.registry/etc/registry/auth/passwd里面，此passwd文件将包含登录凭据和加密的passwd

htpasswd -Bbn admin qdfsdFGC > /data/docker.registry/etc/registry/auth/passwd

4. 验证密码

cat /data/docker.registry/etc/registry/auth/passwd
admin:$2y$05$3R0Y9nlTM.DQEAgSrGCdp.zFMkeRr8ILeK6kW/o0kvlagZLlpUmDG

5. 密码创建完成，将凭据添加到注册表中。在这里,将auth目录挂载到容器中:

docker run -d -p 5000:5000
–restart=always
–name registry_private
-v /data/docker.registry/etc/registry/auth:/etc/registry/auth
-v /data/docker.registry/var/lib/registry:/var/lib/registry
-e “REGISTRY_AUTH=htpasswd”
-e “REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm”
-e “REGISTRY_AUTH_HTPASSWD_PATH=/etc/registry/auth/passwd”
registry:latest

5. 测试

[root@test data]# docker tag registry:latest 127.0.0.1:5000/registry:latest
[root@test data]# docker push 127.0.0.1:5000/registry
The push refers to repository [127.0.0.1:5000/registry]

6d2d8cb41f01: Preparing
4f5aa08c5eaa: Preparing
8ebb9d6ed165: Preparing
0fcbbeeeb0d7: Preparing
no basic auth credentials

6. 认证

[root@test data]# docker login 127.0.0.1:5000
Username (): admin
Password:
Login Succeeded

7. 重试推送

[root@test data]# docker push 127.0.0.1:5000/registry
The push refers to repository [127.0.0.1:5000/registry]
fb6b1a93008f: Pushed
6d2d8cb41f01: Pushed
4f5aa08c5eaa: Pushed

8. 凭据保存在 .docker/config.json中:

[root@test data]# cat ~/.docker/config.json
{
“auths”: {
“127.0.0.1:5000”: {
“auth”: “YWRtaW46ZkZHHGGluVDQ1SA==”
}
}
}

注意： 在使用凭据时建议使用https.
