Centos 7.4 搭建Docker私有镜像库Harbor

玩docker，image们无处安放，头疼+捉急。。。于是决定在虚拟机上，

用Harbor搭建一个私有镜像库，说干就干 :)

1. 准备工作

软件名 版本号

linux Centos7.4

docker 18.03.1-ce

docker-compose 1.21.2

python 2.7

准备工作的步骤省略，如有问题请上网搜索 ：）

2. 安装Harbor

1）从Github上，下载Harbor并解压。

2）修改 harbor.cfg配置文件。

3）在harbor.cfg同级目录下按顺序执行

./prepare

./install.sh

Harbor正常启动的提示信息，如下图。

OK, 再看下Web端，是这个样子滴，就表示没问题。

（默认的登录名密码是：admin/Harbor12345）

到此为止，私有库搭建完毕，测试一下呗。

3. 登录私有库

1）找一台虚拟机，docker login登录私有库。

2）拿busybox举个栗子，打个tag。

4. 上传镜像

用docker push 命令上传至harbor私有库。

总是不放心，还得来Web端看看。。。

5. 下载镜像

6. 注意点

本次配置文件中的hostname不是域名，而是服务器ip，需要在docker的配置文件中添加–insecure-registry server_ip的参数，否则会报如下错误。

这次的centos7.4中，找了半天居然没有找见docker的配置文件，最后手动创建了一个/etc/sysconfig/docker。。。

/etc/sysconfig/docker# Modify these options if you want to change the way the docker daemon runs

OPTIONS='-H tcp://0.0.0.0:4243 -H unix:///var/run/docker.sock'

OPTIONS=" --insecure-registry 192.168.198.XX"

DOCKER_CERT_PATH=/etc/docker

If you want to add your own registry to be used for docker search and docker

pull use the ADD_REGISTRY option to list a set of registries, each prepended

with --add-registry flag. The first registry added will be the first registry

searched.

ADD_REGISTRY='--add-registry registry.access.redhat.com'

If you want to block registries from being used, uncomment the BLOCK_REGISTRY

option and give it a set of registries, each prepended with --block-registry

flag. For example adding docker.io will stop users from downloading images

from docker.io

BLOCK_REGISTRY='--block-registry'

If you have a registry secured with https but do not have proper certs

distributed, you can tell docker to not look for full authorization by

adding the registry to the INSECURE_REGISTRY line and uncommenting it.

INSECURE_REGISTRY='--insecure-registry dl.dockerpool.com:5000'

On an SELinux system, if you remove the --selinux-enabled option, you

also need to turn on the docker_transition_unconfined boolean.

setsebool -P docker_transition_unconfined 1

Location used for temporary files, such as those created by

docker load and build operations. Default is /var/lib/docker/tmp

Can be overriden by setting the following environment variable.

DOCKER_TMPDIR=/var/tmp

Controls the /etc/cron.daily/docker-logrotate cron job status.

To disable, uncomment the line below.

LOGROTATE=false

创建完了配置文件，一定要执行下面两个命令。

systemctl daemon-reload

systemctl restart docker

结果如下，祝各位玩的开心~
