Docker 搭建私有仓库(registry、harbor)

为什么要弄私有仓库，大多是为了速度，我们再私有仓库中的push和pull的速度是特别快的。

利用registry快速搭建

https://hub.docker.com/_/registry/

Run a local registry: Quick Version
$ docker run -d -p 5000:5000 --restart always --name registry registry:2
Now, use it from within Docker:
$ docker pull ubuntu
$ docker tag ubuntu localhost:5000/ubuntu
$ docker push localhost:5000/ubuntu

这是官方的一个小demo。下面是我自己的实践。

# 拉取registry2.0版本
[root@FantJ ~]# docker pull registry:2
Trying to pull repository docker.io/library/registry ...

# tag 镜像
[root@FantJ ~]# docker tag docker.io/nginx 127.0.0.1:5000/nginx
# 上传到私有仓库
[root@FantJ ~]# docker push 127.0.0.1:5000/nginx
The push refers to a repository [127.0.0.1:5000/nginx]7ab428981537: Pushed
82b81d779f83: Pushed
d626a8ad97a1: Pushed

[root@FantJ ~]# 

缺点：没有可视化管理工具，私有仓库服务宕机造成麻烦,没有用户管理机制、没有操作的记录功能。

优点：搭建操作简单

利用harbor搭建

下载地址：https://storage.googleapis.com/harbor-releases/release-1.5.0/harbor-offline-installer-v1.5.1.tgz

wget https://storage.googleapis.com/harbor-releases/release-1.5.0/harbor-offline-installer-v1.5.1.tgz
tar zxvf harbor-offline-installer-v1.5.1.tgz
cd harbor

修改配置harbor.cfg

hostname = fantj.top:8888 

http还是https啥的自己看着改

保存退出，直接运行install.sh

cd ..
./install.sh

注意一点：harbor默认会占用80端口，所以请确保你的80端口不被占用，那怎么修改呢？
