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

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 ... 
2: pulling from docker.io/library/registry
81033e7c1d6a: pull complete 
b235084c2315: pull complete 
c692f3a6894b: pull complete 
ba2177f3a70e: pull complete 
a8d793620947: pull complete 
digest: sha256:672d519d7fd7bbc7a448d17956ebeefe225d5eb27509d8dc5ce67ecb4a0bce54
status: downloaded newer image for docker.io/registry:2
# 后台启动运行
[root@fantj ~]# docker run -d -p 5000:5000 --restart always --name registry registry:2
ce5b8bfa6d7f535906730ea3a058b00e7cfdaaa20ea0db3c49d700a4e2c8a645
[root@fantj ~]# docker images
repository       tag         image id      created       size
docker.io/openjdk    8-jre        bef23b4b9cac    2 weeks ago     443 mb
docker.io/fantj/nginx  latest       ae513a47849c    4 weeks ago     109 mb
docker.io/nginx     latest       ae513a47849c    4 weeks ago     109 mb
docker.io/registry   2          d1fd7d86a825    4 months ago    33.3 mb
# 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 
latest: digest: sha256:e4f0474a75c510f40b37b6b7dc2516241ffa8bde5a442bde3d372c9519c84d90 size: 948
[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：

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？

修改配置docker-compose.yml（需要改端口再进行）

将80:80的第一个80改为自定义的端口号

我在这里改成8888端口。

然后运行install.sh

......
[step 4]: starting harbor ...
creating network "harbor_harbor" with the default driver
creating harbor-log
creating redis
creating registry
creating harbor-db
creating harbor-adminserver
creating harbor-ui
creating nginx
creating harbor-jobservice

✔ ----harbor has been installed and started successfully.----

now you should be able to visit the admin portal at http://fantj.top:8888 . 
for more details, please visit https://github.com/vmware/harbor .

好的，成功了，我们来访问一下。

默认账号密码：
admin
harbor12345

如果想修改，去harbor.cfg修改。

可以看到我们的进程和镜像都多了很多的以vmware开头的（harbor是vmware公司的开源工具）.

好了，开始push测试

[root@fantj harbor]# docker tag docker.io/nginx fantj.top:8888/internet-plus/nginx
[root@fantj harbor]# docker push fantj.top:8888/internet-plus/nginx
the push refers to a repository [fantj.top:8888/internet-plus/nginx]
get https://fantj.top:8888/v1/_ping: dial tcp: lookup fantj.top: no such host

它提示需要用https请求才安全，解决方式有两种：

第一种：docker启动的时候添加对域名+端口的信任 --insecure-registry=xxxx.xx.xx.xx:8888

第二种：添加ssl证书,改天更新

harbor重启

#docker-compose stop
# ./install.sh
