本章内容：

• 安装docker-ce
• 部署harbor仓库
• 上传和拉取

1.安装docker

1）拉取源码 

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

2）安装docker-ce

yum -y install docker-ce

3）查看docker版本

docker -v

4）创建docker-compose软连接

find / -name docker-compose
ln -s /usr/libexec/docker/cli-plugins/docker-compose /usr/local/bin

5）配置镜像加速器并启动docker

  sudo mkdir -p /etc/docker
  sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://6kivj4sd.mirror.aliyuncs.com"]
}
EOF

 sudo systemctl daemon-reload
 sudo systemctl restart docker
 systemctl status docker

2.部署harbor仓库

1）拉取软件包

wget https://github.com/goharbor/harbor/releases/download/v2.10.3/harbor-offline-installer-v2.10.3.tgz

2）解压软件包

tar zxvf harbor-offline-installer-v2.10.3.tgz

3）进入harbor目录，修改配置文件名

cd harbor        \\进入解压harbor目录
mv harbor.yml.tmpl harbor.yml    \\修改一下配置文件名

4）修改配置文件

  1 # Configuration file of Harbor
  2 
  3 # The IP address or hostname to access admin UI and registry service.
  4 # DO NOT use localhost or 127.0.0.1, because Harbor needs to be accessed     by external clients.
  5 hostname: 192.168.182.202        \\修改为主机IP地址
  6 
  7 # http related config
  8 http:
  9   # port for http, default is 80. If https enabled, this port will redire    ct to https port
 10   port: 80        \\端口号可以自定义修改
 11 
 12 # https related config    \\这里注释https 需要开启的话自行开启
 13 #https:
 14   # https port for harbor, default is 443    
 15  # port: 443
 16   # The path of cert and key files for nginx
 17  # certificate: /your/certificate/path
 18  # private_key: /your/private/key/path
 19   # enable strong ssl ciphers (default: false)
 20   # strong_ssl_ciphers: false
 21 

5）安装harbor仓库

./install.sh

6）登录名为admin，密码是Harbor12345

7）登录harbor仓库

3.拉取镜像和上传镜像

1）准备另外一台机器，下载docker 这里不再演示上面有下载演示

2）创建拉取镜像的地址文件（IP地址指定仓库）

cat /etc/docker/daemon.json 
{
	"insecure-registries": ["http://192.168.182.202:80"]
}

3）登录

4）打标签

[root@node03 ~]# docker images    //列出所有镜像 这里提前拉取的httpd镜像
REPOSITORY   TAG       IMAGE ID       CREATED       SIZE
httpd        latest    dabbfbe0c57b   2 years ago   144MB
[root@node03 ~]# docker tag dabbfbe0c57b 192.168.182.202:80/test/web01:v1    //把httpd镜像打上标签

5）推送镜像到harbor仓库

docker push 192.168.182.202:80/test/web01:v1

进入仓库查看是否推送成功

6）拉取镜像命令

[root@node03 ~]# docker pull 192.168.182.202/test/web01:v1    //拉取镜像失败因为这里没有用https证书所以需要指定http的80端口号
Error response from daemon: Get "https://192.168.182.202/v2/": dial tcp 192.168.182.202:443: connect: connection refused
[root@node03 ~]# docker pull 192.168.182.202:80/test/web01:v1    //指定端口号后拉取镜像
