centos7搭建harbor私有镜像仓库

1.准备工作

1.1更换软件源

#更换阿里yum源
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
yum makecache

#更换阿里docker源
yum install -y yum-utils
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

1.2 修改主机名

hostnamectl set-hostname harbor

#修改/etc/hosts,同步到使用私有镜像库的每个节点
echo "192.168.153.139 docker.io" >>/etc/hosts

1.3 同步时间

yum install chrony ntpdate -y
sed "s/^server/#server/g" /etc/chrony.conf
echo 'server tiger.sina.com.cn iburst' >> /etc/chrony.conf
echo 'server ntp1.aliyun.com iburst' >> /etc/chrony.conf
systemctl enable chronyd ; systemctl start chronyd
ntpdate tiger.sina.com.cn

1.4 安装docker和docker-compose

安装docker

yum install docker-ce -y
systemctl start docker
systemctl enable docker

安装docker-compose

#1.下载Docker Compose的可执行文件。可以使用以下命令下载最新版本：
sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
#2.赋予可执行权限给下载的二进制文件：
sudo chmod +x /usr/local/bin/docker-compose
#3.创建一个符号链接，将docker-compose命令链接到/usr/bin目录，以便可以全局访问
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
#4.验证安装是否成功
docker-compose --version

1.5 下载harbor离线安装包

去harbor github下载离线安装包，版本可自行选择。下载完成后解压。

[root@localhost ~]# tar xzvf harbor-offline-installer-v2.10.3.tgz
harbor/harbor.v2.10.3.tar.gz
harbor/prepare
harbor/LICENSE
harbor/install.sh
harbor/common.sh
harbor/harbor.yml.tmpl

2.配置harbor

切换至解压目录后，修改harbor.yml文件。

cp harbor.yml.tmpl harbor.yml     # 注意文件名必须是harbor.yml

最主要的是更改标红内容，除hostname外，其余的都可以保持默认。

如果仅测试环境不需要启用https的话，可以把https的所有内容注释掉。

3.执行安装命令

[root@localhost harbor]# ./install.sh

如果你配置的harbor使用http协议，则需要编辑docker主配置文件daemon.json加入insecure-registries，centos目录为/etc/docker/daemon.json

[root@harbor ~]# cat /etc/docker/daemon.json 
{
"insecure-registries":["http://docker.io"]#替换为你的域名
}

更改后重启docker

# 重载配置文件
systemctl daemon-reload

# 重启docker
systemctl restart docker

# 停止所有容器
docker-compose down -v    

# 启动所有容器
docker-compose up -d

#配置开机自启
chmod +x /etc/rc.d/rc.local
echo "/usr/bin/docker-compose -f /你的路径/docker-compose.yml up -d" >> /etc/rc.d/rc.local

4.测试

访问harbor服务器地址，看到截图说明搭建成功

#命令行登录到仓库
docker login 你的harbor地址
