CentOS7搭建Harbor企业级docker仓库

安装Harbor，首先要安装docker 和 docker-compose

1.安装docker

（1）安装一些必要的系统工具

$ yum install -y yum-utils device-mapper-persistent-data lvm2

（2）添加软件源信息

$ yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

（3）更新 yum 缓存

$ yum makecache fast

（4）安装 Docker-ce

$ yum -y install docker-ce

（5）启动 Docker 后台服务

$ systemctl start docker

2.安装docker-compose

（1）下载二进制文件

$ curl -L https://github.com/docker/compose/releases/download/1.16.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

（2）赋予二进制文件可执行权限

$ chmod +x /usr/local/bin/docker-compose

（3）根据自己的情况决定是否安装命令补全功能

$ yum install bash-completion 
$ curl -L https://raw.githubusercontent.com/docker/compose/1.16.1/contrib/completion/bash/docker-compose -o /etc/bash_completion.d/docker-compose

（4）测试是否安装成功

$ docker-compose --version

3.安装harbor

（1）下载

$ wget -P /usr/local/src/  https://github.com/vmware/harbor/releases/download/v1.2.0/harbor-online-installer-v1.2.0.tgz

（2）解压

$ tar zxf harbor-online-installer-v1.2.0.tgz  -C /usr/local/

（3）修改配置文件

$ cd /usr/local/harbor/
$ vim /usr/local/harbor/harbor.cfg

修改 hostname = harbor （启动harbor为主机名）

否则会报异常：

➜ Please set hostname and other necessary attributes in harbor.cfg first. DO NOT use localhost or 127.0.0.1 for hostname, because Harbor needs to be accessed by external clients.

Please set --with-notary if needs enable Notary in Harbor, and set ui_url_protocol/ssl_cert/ssl_cert_key in harbor.cfg bacause notary must run under https.

Please set --with-clair if needs enable Clair in Harbor

（4）执行安装

$ ./install.sh

（5）访问： http://192.168.38.23/harbor/sign-in

默认账号密码： admin / Harbor12345 登录后修改密码

（6）启动和重启

Harbor 的日常运维管理是通过docker-compose来完成的，Harbor本身有多个服务进程，都放在docker容器之中运行，我们可以通过docker ps命令查看。

查看Harbor
# docker-compose ps
启动Harbor
# docker-compose start
停止Harbor
# docker-comose stop
重启Harbor
# docker-compose restart

如果是用 docker-compose start 会报错：

 
       ERROR: for nginx  UnixHTTPConnectionPool(host='localhost', port=None): Read timed out. (read timeout=60) 
      
       ERROR: for harbor-log  UnixHTTPConnectionPool(host='localhost', port=None): Read timed out. (read timeout=60) 
      
       ERROR: An HTTP request took too long to complete. Retry with --verbose to obtain debug information.

因此使用 docker-compose up -d 启动

4. 上传和下载

（1）配置daemon.json

$ vim /etc/docker/daemon.json

{
　　"registry-mirrors": ["https://njrds9qc.mirror.aliyuncs.com"],
　　"insecure-registries":["192.168.38.23"]
}

然后依次执行如下命令：

$ docker-compose stop
$ systemctl daemon-reload
$ systemctl restart docker
$ docker-compose up -d

（2）客户端将镜像打tag

命令格式：docker tag SOURCE_IMAGE[:TAG] harbor/library/IMAGE[:TAG]

docker tag 83f3f8af3613 192.168.38.23/library/tomcat:7.0.69-jre7

（3）客户端push镜像之前，先登录服务端

$ docker login 192.168.38.23
Username: admin
Password:

用户名密码：admin / Harbor12345

备注：如果登录时出现 Error response from daemon: Get http://192.168.38.23/v2/: Get http://harbor/service/token?account=admin&client_id=docker&offline_token=true&service=harbor-registry: dial tcp: lookup harbor on 192.168.38.2:53: no such host.

则需要执行第5步操作，配置TLS证书

（4）客户端push

push命令格式： docker push harbor/library/IMAGE[:TAG]

$ docker push 192.168.38.23/library/tomcat:7.0.69-jre7

5.Harbor配置TLS证书

（1）修改Harbor配置文件

因为Harbor默认使用http协议访问，所以我们这里在配置文件中，开启https配置；

配置harbor.cfg

hostname = 192.168.38.23
ui_url_protocol = https
ssl_cert = /etc/certs/ca.crt
ssl_cert_key = /etc/certs/ca.key

（2）创建自签名证书key文件

$ mkdir /etc/certs
$ openssl genrsa -out /etc/certs/ca.key 2048
Generating RSA private key, 2048 bit long modulus
....+++
..................................................+++
e is 65537 (0x10001)

（3）创建自签名证书crt文件

$ openssl req -x509 -new -nodes -key /etc/certs/ca.key -subj "/CN=192.168.38.23" -days 5000 -out /etc/certs/ca.crt

（4）开始安装Harbor

$ ./install.sh

（5）客户端配置

客户端需要创建证书文件存放的位置，并且把服务端创建的证书拷贝到该目录下，然后重启客户端docker

$ mkdir -p /etc/docker/certs.d/192.168.38.23

把服务端crt证书文件拷贝到客户端，这里的客户端为192.168.38.21

$ scp /etc/certs/ca.crt [email protected]:/etc/docker/certs.d/192.168.38.23/

重启客户端docker

$ systemctl restart docker

$ docker login 192.168.38.23
Username: admin
Password: 
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded
$ docker push 192.168.38.23/library/tomcat:7.0.69-jre7

push成功后登录Harbor可查看刚才上传的镜像，这里的链接地址也变成了https了 https://192.168.38.23/harbor/sign-in

（6）客户端docker pull 测试
