使用Harbor搭建Docker私有仓库

ip:192.168.0.145

环境设置
防火墙，selinux等，可以使用本章开头的那个shell脚本

其他主机的hosts文件也都添加上
ip hub.aaa.com

windows系统的hosts也修改

安装docker,启动，开机启动
其他主机也都加上这个

vim /etc/docker/daemon.json

{
    "exec-opts": ["native.cgroupdriver=systemd"],
    "log-driver": "json-file",
    "log-opts": {
        "max-size": "100m"
    },
    "insecure-registries": ["https://hub.aaa.com"] # 仓库地址
}

添加后重启docker

下载配置docker-compose
官方地址：https://docs.docker.com/compose/install/

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
docker-compose --version

chmod a+x *

# 再次编辑配置文件，配置上证书
vim /usr/local/harbor/harbor.yml

# 查看
docker ps -a

# 打开浏览器访问https://hub.aaa.com
# 用户名：admin

测试

# 其他节点主机下载镜像推送到仓库,使用的是一个测试的镜像
docker pull wangyanglinux/myapp:v1

# web页面，项目，library,镜像仓库，右上角有一个推送镜像：
# 在项目中标记镜像：docker tag SOURCE_IMAGE[:TAG] hub.aaa.com/library/IMAGE[:TAG]
# 推送镜像到当前项目：docker push hub.aaa.com/library/IMAGE[:TAG]

# 给镜像重新打标签
docker tag wangyanglinux/myapp:v1 hub.aaa.com/library/myapp:v1

# 需要先登陆，然后才能push
docker push hub.aaa.com/library/myapp:v1

# 此时在web界面就可以查看到推送过来的镜像
