什么是 Harbor?
第一次使用這個(gè)的時(shí)候是剛進(jìn)公司處理的第一個(gè)任務(wù)的時(shí)候,發(fā)現(xiàn) Harbor 就是一個(gè)用于存儲(chǔ)和分發(fā) Docker 鏡像的企業(yè)級(jí)Registry 服務(wù)器。
網(wǎng)上找到一個(gè) Harbor 的架構(gòu)圖:
Harbor 是 VMware 公司開(kāi)源的企業(yè)級(jí) DockerRegistry 項(xiàng)目,項(xiàng)目地址為 https://github.com/vmware/harbor。其目標(biāo)是幫助用戶(hù)迅速搭建一個(gè)企業(yè)級(jí)的 Docker registry 服務(wù)。它以 Docker 公司開(kāi)源的 registry 為基礎(chǔ),提供了管理UI,基于角色的訪(fǎng)問(wèn)控制(Role Based Access Control),AD/LDAP集成、以及審計(jì)日志(Auditlogging) 等企業(yè)用戶(hù)需求的功能,同時(shí)還原生支持中文。Harbor 的每個(gè)組件都是以 Docker 容器的形式構(gòu)建的,使用 Docker Compose 來(lái)對(duì)它進(jìn)行部署。
環(huán)境準(zhǔn)備
1、自己在騰訊云買(mǎi)的服務(wù)器(CentOS7.3)
2、Docker 版本:17.05.0-ce
3、Docker-compose:1.17.1
4、Harbor:1.1.2
安裝 Docker
因?yàn)橄到y(tǒng)是 CentOS 7.3 ,內(nèi)核啥的都已經(jīng)是 3.10,所以不用擔(dān)心內(nèi)核升級(jí)的問(wèn)題,一些操作啥的在 7.x 上操作也很方便。
yum update //系統(tǒng)版本更新 vim /etc/yum.repos.d/docker.repo //添加以下內(nèi)容 [dockerrepo] name=Docker Repository baseurl=https://yum.dockerproject.org/repo/main/centos/7/ enabled=1 gpgcheck=1 gpgkey=https://yum.dockerproject.org/gpg //下面安裝 Docker 引擎 yum install docker-engine -y //安裝docker引擎,此步也可作為更新docker版本的操作:先#systemctl stop docker 停止docker服務(wù),再#yum install docker-engine 更新docker版本 systemctl enable docker.service systemctl start docker //啟動(dòng)docker守護(hù)進(jìn)程 docker info //查看docker運(yùn)行情況 docker -v //查看版本信息
修改 Docker 配置文件 /etc/default/docker 如下:
使用 service docker restart
重啟 Docker 服務(wù)即可。
或者用官方提供的方式:
安裝 Docker-compose
如果是想直接命令安裝也行,
下載指定版本的docker-compose
[code]
sudo curl -L https://github.com/docker/compose/releases/download/1.17.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
對(duì)二進(jìn)制文件賦可執(zhí)行權(quán)限
chmod +x /usr/local/bin/docker-compose
測(cè)試下docker-compose是否安裝成功
docker-compose --version
出現(xiàn)如下
docker-compose version 1.17.1, build 6d101fb
但是,這種方法簡(jiǎn)直龜速,幸好還有種方法,
見(jiàn)這里:https://docs.docker.com/compose/install/#install-compose
這種需要通過(guò) Python 的 pip 安裝
安裝 pip
wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-1.4.2.tar.gz tar -vxf setuptools-1.4.2.tar.gz cd setuptools-1.4.2 python2.7 setup.py install //因?yàn)榉?wù)器自帶 Python 2.7 easy_install-2.7 pip
安裝 docker compose
pip install docker-compose docker-compose --version //測(cè)試安裝是否成功
安裝 Harbor
wget https://github.com/vmware/harbor/releases/download/v1.1.2/harbor-offline-installer-v1.1.2.tgz #離線(xiàn)安裝包,也是龜速,把這個(gè)下載鏈接用迅雷下載,速度卻賊快,嘿嘿,然后再傳到服務(wù)器上去,整個(gè)過(guò)程快很多! tar -zxvf harbor-offline-installer-v1.1.2.tgz
解壓縮之后,進(jìn)入目錄下會(huì)看到 harbor.cfg 文件,該文件就是 Harbor 的配置文件。

啟動(dòng) harbor,修改完配置文件后,在的當(dāng)前目錄執(zhí)行./install.sh
,Harbor服務(wù)就會(huì)根據(jù)當(dāng)期目錄下的docker-compose.yml
開(kāi)始下載依賴(lài)的鏡像,檢測(cè)并按照順序依次啟動(dòng)各個(gè)服務(wù)。
啟動(dòng)完成后,我們?cè)L問(wèn)剛設(shè)置的 hostname 即可,http://115.159.227.249/,默認(rèn)是80端口,如果端口占用,我們可以去修改docker-compose.yml文件中,對(duì)應(yīng)服務(wù)的端口映射。
登錄 Web Harbor , 輸入用戶(hù)名 admin,默認(rèn)密碼(或已修改密碼)登錄系統(tǒng)。
我們可以看到系統(tǒng)各個(gè)模塊如下:
項(xiàng)目:新增/刪除項(xiàng)目,查看鏡像倉(cāng)庫(kù),給項(xiàng)目添加成員、查看操作日志、復(fù)制項(xiàng)目等
日志:倉(cāng)庫(kù)各個(gè)鏡像create、push、pull等操作日志
系統(tǒng)管理
其他設(shè)置
注意:非系統(tǒng)管理員用戶(hù)登錄,只能看到有權(quán)限的項(xiàng)目和日志,其他模塊不可見(jiàn)。
我們要嘗試下能不能把自己 Docker 里面的鏡像 push 到 Harbor 的 library 里來(lái)(默認(rèn)這個(gè) library 項(xiàng)目是公開(kāi)的,所有人都可以有讀的權(quán)限,都不需要 docker login 進(jìn)來(lái),就可以拉取里面的鏡像)。
注意:
為了后面留坑,我這里先 在自己的 docker.service 中添加倉(cāng)庫(kù):(這是個(gè)坑,建議你先按照我說(shuō)的做,不然下面可能會(huì)一直登錄不上)
vim /usr/lib/systemd/system/docker.service #里面的這行修改為:(其實(shí)就是添加 --insecure-registry 115.159.227.249 ) ExecStart=/usr/bin/dockerd --insecure-registry 115.159.227.249
添加完了后重新啟動(dòng) docker:
systemctl daemon-reload && systemctl enable docker && systemctl start docker
啟動(dòng) docker 服務(wù):
service docker start
登錄:(為了測(cè)試下能否登錄成功)
admin登錄 $ docker login 115.159.227.249 Username: admin Password: Login Succeeded
打 tag 并 push
docker tag ubuntu:15.10 115.159.227.249/library/ubuntu:15.10 //給我的鏡像打個(gè) tag docker push 115.159.227.249/library/ubuntu The push refers to a repository [115.159.227.249/library/ubuntu] 98d59071f692: Pushed af288f00b8a7: Pushed 4b955941a4d0: Pushed f121afdbbd5d: Pushed 15.10: digest: sha256:ec89c4a90f45f5e103860191890f48d8379e0504a2881ff706aef0768dc0321b size: 1150
上傳完畢后,登錄Web Harbor,選擇項(xiàng)目 library,就可以看到我剛 push 的鏡像了。
同理,你也可以測(cè)試下從 Harbor pull 鏡像到你的 Docker 中去,這里就不繼續(xù)演示了。
