Harbor概述
Habor是由VMWare公司開源的容器鏡像倉庫。事實上，Habor是在Docker Registry上進行了相應的
企業級擴展，從而獲得了更加廣泛的應用，這些新的企業級特性包括：管理用戶界面，基於角色的訪
問控制 ，AD/LDAP集成以及審計日誌等，足以滿足基本企業需求。

Harbor部署
Harbor安裝有3種方式：
• 在線安裝：從Docker Hub下載Harbor相關鏡像，因此安裝軟件包非常小
• 離線安裝：安裝包包含部署的相關鏡像，因此安裝包比較大
• OVA安裝程序：當用戶具有vCenter環境時，使用此安裝程序，在部署OVA後啓動Harbor

包路徑： 鏈接：https://pan.baidu.com/s/1QhCjEAoEepqELhm9IvMOTA
有了harbor就不需要連外網下載鏡像了。harbor一般部署在宿主機上。
我們將harbor的包上傳到主機上，解壓，配置。需要修改一下訪問地址，我們這裏配置成本機ip，修改一下密碼，默認登錄密碼Harbor12345 。
[root@mcwk8s01 ~]# ls anaconda-ks.cfg harbor-offline-installer-v1.6.1.tgz keepalived.conf nginx.sh [root@mcwk8s01 ~]# tar xf harbor-offline-installer-v1.6.1.tgz [root@mcwk8s01 ~]# ls anaconda-ks.cfg harbor harbor-offline-installer-v1.6.1.tgz keepalived.conf nginx.sh [root@mcwk8s01 ~]# cd harbor/ [root@mcwk8s01 harbor]# ls common docker-compose.chartmuseum.yml docker-compose.clair.yml docker-compose.notary.yml docker-compose.yml ha harbor.cfg harbor.v1.6.1.tar.gz install.sh LICENSE NOTICE open_source_license prepare [root@mcwk8s01 harbor]# vim harbor.cfg [root@mcwk8s01 harbor]# egrep "10.0.0.31|Harbor12345" harbor.cfg hostname = 10.0.0.31 harbor_admin_password = Harbor12345 [root@mcwk8s01 harbor]#
如果需要使用https那修改下配置：ui_url_protocol = http
它是使用docker compose來編排部署的。所以我們可以去去下載一個。安裝方式如下鏈接參考
因爲harbor自己要起nginx，會佔用80服務，我們主機1上有nginx。那麼我們換到主機5上面去把=吧

推送鏡像到harbor
推送總結
1、配置http鏡像倉庫可信任
# vi /etc/docker/daemon.json
{"insecure-registries":["reg.ctnrs.com"]}
# systemctl restart docker
2、打標籤
# docker tag centos:6 reg.ctnrs.com/library/centos:6
3、上傳
# docker push reg.ctnrs.com/library/centos:6
4、下載
# docker pull reg.ctnrs.com/library/centos:6
推送案例
如推薦的推送案例，我們需要打上標籤，標籤地址是我們的項目訪問地址，然後push這個有倉庫地址標籤的鏡像

點擊進入，看到推送的信息
我們再把nginx推送上去，把tomcat再推送第二個版本上去。需要注意的是，我們推送前一定要打上我們自己倉庫的地址的鏡像標籤，推送這個有標籤的鏡像，別直接推送未打標籤的，省的推送到別人的倉庫了。

我們再看下，這個倉庫中的tomcat有兩個版本了
倉庫中有兩個鏡像
我們想要下載指定鏡像指定版本的話可以在這裏看下載地址，複製命令
比如上面我們複製的是 docker pull 10.0.0.35/library/tomcat:v1
我們在另一臺主機，主機6上下載一下。我們下載的主機，由於harbor是http方式的，我們也需要添加配置，讓harbor主機是受信任的
