docker私有仓库搭建及认证

霸气de小男生 提交于 2020-01-12 08:40:03

什么是docker?

Docker 是一个开源的应用容器引擎,让开发者可以打包他们的应用以及依赖包到一个可移植的容器中,然后发布到任何流行的 Linux 机器上,也可以实现虚拟化。容器是完全使用沙箱机制,相互之间不会有任何接口。

再具体的请自行百度~

 

命令是红字,配置是绿字,注释和其他为黑色字体。现在让我们来安装吧

服务器主机名及IP地址:

192.168.110.92 docker-registry

192.168.110.22 docker-gitlab

系统版本:

CentOS Linux release 7.2.1511 (Core)

 

docker版本:

Docker version 1.12.6, build c4618fb/1.12.6

docker仓库版本:

registry-2.4.1

docker认证版本:

docker_auth:1

 

基础优化~略

 

关闭selinux:
sed -i s#'SELINUX=enforcing'#'SELINUX=disabled'#g /etc/selinux/config
setenforce 0

关闭防火墙:

systemctl stop firewalld

systemctl disable firewalld

 

安装源:

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

 

安装并启动docker:

yum install docker docker-registry -y

systemctl enable docker

systemctl start docker

 

私有镜像库和认证搭建:

下载镜像:

docker pull registry 

docker pull docker_auth:1 

打标记:

docker tag registry  192.168.110.92:5000/registry:2.4.1

docker tag docker_auth:1  192.168.110.92:5000/docker_auth

修改docker文件 加一行--insecure-registry 192.168.110.92:5000

vim /etc/sysconfig/docker

# /etc/sysconfig/docker

# Modify these options if you want to change the way the docker daemon runs

OPTIONS='--selinux-enabled --log-driver=journald --signature-verification=false --insecure-registry 192.168.110.92:5000'

if [ -z "${DOCKER_CERT_PATH}" ]; then

    DOCKER_CERT_PATH=/etc/docker

fi

创建目录并进入:

mkidr /data/auth_server/ssl/ -p                       ##用于存放证书

mkidr /data/auth_server/config/ -p                    ##配置文件

cd /data/auth_server/ssl/

 

证书生成(server.key,server.pem和server.crt):

openssl genrsa -out server.key 2048

openssl req -newkey rsa:2048 -nodes -keyout server.key -x509 -days 3650 -out server.pem

cat server.pem | tee -a server.crt

拷贝:

scp server.crt 192.168.110.22:/etc/docker/certs.d/   ###scp 到其他服务器用于测试从内部仓库下载

现在创建配置文件:

cd /data/auth_server/config

vi auth_config.yml

server:

  addr: ":5001"

  certificate: "/ssl/server.pem" 

  key: "/ssl/server.key"

 

token:

  issuer: "Auth Service"  # Must match issuer in the Registry config.

  expiration: 900

 

users:

  # Password is specified as a BCrypt hash. Use htpasswd -B to generate.

  "admin":

    password: "$2y$05$LO.vzwpWC5LZGqThvEfznu8qhb5SGqvBSWY1J3yZ4AxtMRZ3kN5jC"                     #badmin

  "test":

    password: "123"  

 

acl:

  - match: {account: "admin"}

    actions: ["*"]

    comment: "Admin has full access to everything."

  - match: {account: ""}

    actions: ["pull"]

    comment: "User \"user\" can pull stuff."

回到家目录创建docker-compose配置文件
cd && vi docker-compose.yml

dockerauth:

  image: cesanta/docker_auth:1

  ports:

    - "5001:5001"

  volumes:

    - /data/auth_server/config:/config:ro

    - /var/log/docker_auth:/logs

    - /data/auth_server/ssl:/ssl

  command: /config/auth_config.yml

  restart: always

 

registry:

  image: registry:2.4.1

  ports:

    - "5000:5000"

  volumes:

    - /data/auth_server/ssl:/ssl

    - /data/docker_registry/data:/var/lib/registry

    - /data/auth_server/config:/auth

    - /data/auth_server/ssl:/certs

  restart: always

  environment:

    - REGISTRY_HTTP_TLS_CERTIFICATE=/certs/server.crt

    - REGISTRY_HTTP_TLS_KEY=/certs/server.key

    - REGISTRY_AUTH=token

    - REGISTRY_AUTH_TOKEN_REALM=https://192.168.110.92:5001/auth ###本机ip

    - REGISTRY_AUTH_TOKEN_SERVICE="Docker registry"

    - REGISTRY_AUTH_TOKEN_ISSUER="Auth Service"

    - REGISTRY_AUTH_TOKEN_ROOTCERTBUNDLE=/certs/server.pem

 

启动并查看:

docker-compose up -d  #-d后台启动

docker-compose ps

      Name                     Command               State           Ports         

-----------------------------------------------------------------------------------

root_dockerauth_1   /docker_auth/auth_server / ...   Up      0.0.0.0:5001->5001/tcp

root_registry_1     /bin/registry serve /etc/d ...   Up      0.0.0.0:5000->5000/tcp

 

上传打完包的镜像到私有仓库:

for n in `docker images |grep 192|awk '{print $1":"$2}'` ;do docker push $n;done

验证镜像是否在镜像库(没有404就行):

for YZ in `docker images|awk -F "[/ ]+" '{print $2}'|grep -v TAG`;do curl -v -X GET http://192.168.110.92:5000/v2/$YZ/tags/list ;done

 

测试:

192.168.110.22服务器执行:

docker login 192.168.110.92:5000

 

账号: admin      #auth_config.yml 配置的

密码: badmin    #auth_config.yml配置的

Login Succeeded        ##说明成功

docker pull 192.168.110.92:5000/docker_auth        #不出意外的话应该是飞快的速度
