Docker容器應用的開發和運行離不開可靠的鏡像管理,雖然Docker官方也提供了公共的鏡像倉庫,可是從安全和效率等方面考慮,部署咱們私有環境內的Registry
也是很是必要的。以前介紹了Docker私有倉庫Registry,這裏介紹另外一款企業級Docker鏡像倉庫Harbor的部署和使用,在Kubernetes集羣中,推薦使用Harbor倉庫環境。html
1、Harbor倉庫介紹前端
咱們在平常Docker容器使用和管理過程當中,漸漸發現部署企業私有倉庫每每是頗有必要的, 它能夠幫助你管理企業的一些敏感鏡像, 同時因爲Docker Hub的下載速度和GFW的緣由, 每每須要將一些沒法直接下載的鏡像導入本地私有倉庫. 而Harbor就是部署企業私有倉庫的一個不二之選。Harbor是由VMware公司開源的企業級的Docker Registry管理項目,Harbor主要提供Dcoker Registry管理UI,提供的功能包括:基於角色訪問的控制權限管理(RBAC)、AD/LDAP集成、日誌審覈、管理界面、自我註冊、鏡像複製和中文支持等。Harbor的目標是幫助用戶迅速搭建一個企業級的Docker registry服務。它以Docker公司開源的registry爲基礎,額外提供了以下功能:
-> 基於角色的訪問控制(Role Based Access Control)
-> 基於策略的鏡像複製(Policy based image replication)
-> 鏡像的漏洞掃描(Vulnerability Scanning)
-> AD/LDAP集成(LDAP/AD support)
-> 鏡像的刪除和空間清理(Image deletion & garbage collection)
-> 友好的管理UI(Graphical user portal)
-> 審計日誌(Audit logging)
-> RESTful API
-> 部署簡單(Easy deployment)node
Harbor的全部組件都在Dcoker中部署,因此Harbor可以使用Docker Compose快速部署。須要特別注意:因爲Harbor是基於Docker Registry V2版本,因此docker必須大於等於1.10.0版本,docker-compose必需要大於1.6.0版本!python
2、Harbor倉庫結構mysql
Harbor的每一個組件都是以Docker容器的形式構建的,可使用Docker Compose來進行部署。若是環境中使用了kubernetes,Harbor也提供了kubernetes的配置文件。Harbor大概須要如下幾個容器組成:ui(Harbor的核心服務)、log(運行着rsyslog的容器,進行日誌收集)、mysql(由官方mysql鏡像構成的數據庫容器)、Nginx(使用Nginx作反向代理)、registry(官方的Docker registry)、adminserver(Harbor的配置數據管理器)、jobservice(Harbor的任務管理服務)、redis(用於存儲session)。linux
Harbor是一個用於存儲和分發Docker鏡像的企業級Registry服務器,總體架構仍是很清晰的。下面借用了網上的架構圖:nginx
===========================================================================git
Harbor依賴的外部組件
-> Nginx(即Proxy代理層): Nginx前端代理,主要用於分發前端頁面ui訪問和鏡像上傳和下載流量; Harbor的registry,UI,token等服務,經過一個前置的反向代理統一接收瀏覽器、Docker客戶端的請求,並將請求轉發給後端不一樣的服務。
-> Registry v2: 鏡像倉庫,負責存儲鏡像文件; Docker官方鏡像倉庫, 負責儲存Docker鏡像,並處理docker push/pull命令。因爲咱們要對用戶進行訪問控制,即不一樣用戶對Docker image有不一樣的讀寫權限,Registry會指向一個token服務,強制用戶的每次docker pull/push請求都要攜帶一個合法的token, Registry會經過公鑰對token進行解密驗證。
-> Database(MySQL或Postgresql):爲core services提供數據庫服務,負責儲存用戶權限、審計日誌、Docker image分組信息等數據。github
Harbor自有組件
-> Core services(Admin Server): 這是Harbor的核心功能,主要提供如下服務:
-> UI:提供圖形化界面,幫助用戶管理registry上的鏡像(image), 並對用戶進行受權。
-> webhook:爲了及時獲取registry 上image狀態變化的狀況, 在Registry上配置webhook,把狀態變化傳遞給UI模塊。
-> Auth服務:負責根據用戶權限給每一個docker push/pull命令簽發token. Docker 客戶端向Regiøstry服務發起的請求,若是不包含token,會被重定向到這裏,得到token後再從新向Registry進行請求。
-> API: 提供Harbor RESTful API
-> Replication Job Service:提供多個 Harbor 實例之間的鏡像同步功能。
-> Log collector:爲了幫助監控Harbor運行,負責收集其餘組件的log,供往後進行分析。web
再來仔細看下Harbor主要組件和數據流走向:
-> proxy,它是一個nginx前端代理,主要是分發前端頁面ui訪問和鏡像上傳和下載流量,上圖中經過深藍色先標識;
-> ui提供了一個web管理頁面,固然還包括了一個前端頁面和後端API,底層使用mysql數據庫;
-> registry是鏡像倉庫,負責存儲鏡像文件,當鏡像上傳完畢後經過hook通知ui建立repository,上圖經過紅色線標識,固然registry的token認證也是經過ui組件完成;
-> adminserver是系統的配置管理中心附帶檢查存儲用量,ui和jobserver啓動時候回須要加載adminserver的配置,經過灰色線標識;
-> jobsevice是負責鏡像複製工做的,他和registry通訊,從一個registry pull鏡像而後push到另外一個registry,並記錄job_log,上圖經過紫色線標識;
-> log是日誌彙總組件,經過docker的log-driver把日誌彙總到一塊兒,經過淺藍色線條標識。
Harbor的誤區
誤區一: Harbor是負責存儲容器鏡像的 (Harbor是鏡像倉庫,那麼它就應當是存儲鏡像的)
其實關於鏡像的存儲,Harbor使用的是官方的docker registry服務去完成,至於registry是用本地存儲或者s3都是能夠的,Harbor的功能是在此之上提供用戶權限管理、鏡像複製等功能,提升使用的registry的效率。
誤區二:Harbor鏡像複製是存儲直接複製 (鏡像的複製,不少人覺得應該是鏡像分層文件的直接拷貝)
其實Harbor鏡像複製採用了一個更加通用、高屋建瓴的作法,經過docker registry 的API去拷貝,這不是省事,這種作法屏蔽了繁瑣的底層文件操做、不只能夠利用現有docker registry功能沒必要重複造輪子,並且能夠解決衝突和一致性的問題。
Harbor的部署
這裏不建議使用kubernetes來部署, 緣由是鏡像倉庫很是重要, 儘可能保證部署和維護的簡潔性, 所以這裏直接使用compose的方式進行部署。官方提供3種部署Harbor的方式:
1)在線安裝: 從Docker Hub下載Harbor的鏡像來安裝, 因爲Docker Hub比較慢, 建議Docker配置好加速器。
2)離線安裝: 這種方式應對與部署主機沒聯網的狀況使用。須要提早下載離線安裝包: harbor-offline-installer-.tgz 到本地
3)OVA安裝: 這個主要用vCentor環境是使用
後面部署時會爲Docker配置鏡像加速器, 所以會採用在線部署的方式, 部署步驟以下:
-> 下載Harbor最新的在線安裝包
-> 配置Harbor (harbor.cfg)
-> 運行install.sh來安裝和啓動Harbor
-> Harbor的日誌路徑:/var/log/harbor
Harbor倉庫部署的官方要求的最小系統配置
-> 2個cpu
-> 4g內存
-> 40g硬盤,由於是存儲鏡像的因此推薦硬盤大點。

3、Harbor倉庫環境部署記錄
3.1) 環境要求和準備工做
Harbor以容器的形式進行部署, 所以能夠被部署到任何支持Docker的Linux發行版, 要使用Harbor,須要安裝docker和docker-compose編排工具,而且具有以下環境: Python2.7+ Docker Engine 1.10+ Docker Compose 1.6.0+ 這裏測試環境部署到Centos7.5機器上,以下: [root@harbor-node ~]# cat /etc/redhat-release CentOS Linux release 7.6.1810 (Core) [root@harbor-node ~]# setenforce 0 [root@harbor-node ~]# cat /etc/sysconfig/selinux ........... SELINUX=disabled [root@harbor-node ~]# systemctl stop firewalld [root@harbor-node ~]# systemctl disable firewalld [root@harbor-node ~]# firewall-cmd --state not running centos7自帶的python版本就是2.7.5 [root@harbor-node ~]# python --version Python 2.7.5
3.2) 安裝Docker
更新yum包 [root@harbor-node ~]# yum update 卸載舊版本 Docker [root@harbor-node ~]# yum remove docker docker-common docker-selinux docker-engine 安裝軟件包 [root@harbor-node ~]# yum install -y yum-utils device-mapper-persistent-data lvm2 添加 Docker yum源 [root@harbor-node ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo Loaded plugins: fastestmirror adding repo from: https://download.docker.com/linux/centos/docker-ce.repo grabbing file https://download.docker.com/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo repo saved to /etc/yum.repos.d/docker-ce.repo 安裝 Docker (直接yum按照docker-ce便可) 隨着Docker的不斷流行與發展,docker公司(或稱爲組織)也開啓了商業化之路,Docker 從 17.03版本以後分爲 CE(Community Edition) 和 EE(Enterprise Edition): 1) Docker EE由公司支持,可在通過認證的操做系統和雲提供商中使用,並可運行來自Docker Store的、通過認證的容器和插件。 2) Docker CE是免費的Docker產品的新名稱,Docker CE包含了完整的Docker平臺,很是適合開發人員和運維團隊構建容器APP。 事實上,Docker CE 17.03,可理解爲Docker 1.13.1的Bug修復版本。所以,從Docker 1.13升級到Docker CE 17.03風險相對是較小的。 [root@harbor-node ~]# yum -y install docker-ce 啓動 Docker [root@harbor-node ~]# systemctl start docker [root@harbor-node ~]# systemctl enable docker [root@harbor-node ~]# systemctl status docker ● docker.service - Docker Application Container Engine Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: disabled) Active: active (running) since Sun 2019-05-26 22:15:34 CST; 27min ago Docs: https://docs.docker.com Main PID: 15260 (dockerd) CGroup: /system.slice/docker.service └─15260 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock May 26 22:15:33 harbor-node dockerd[15260]: time="2019-05-26T22:15:33.570826805+08:00" level=info msg="pickfirstBalancer: HandleSubConnStateChange: 0xc420175490, READY" module=grpc May 26 22:15:33 harbor-node dockerd[15260]: time="2019-05-26T22:15:33.570899114+08:00" level=info msg="pickfirstBalancer: HandleSubConnStateChange: 0xc42006de20, READY" module=grpc May 26 22:15:33 harbor-node dockerd[15260]: time="2019-05-26T22:15:33.665440742+08:00" level=info msg="Graph migration to content-addressability took 0.00 seconds" May 26 22:15:33 harbor-node dockerd[15260]: time="2019-05-26T22:15:33.666111994+08:00" level=info msg="Loading containers: start."

Hint: Some lines were ellipsized, use -l to show in full. 查看 Docker 版本號 [root@harbor-node ~]# docker --version Docker version 18.09.6, build 481bc77156 [root@harbor-node ~]# docker version Client: Version: 18.09.6 API version: 1.39 Go version: go1.10.8 Git commit: 481bc77156 Built: Sat May 4 02:34:58 2019 OS/Arch: linux/amd64 Experimental: false Server: Docker Engine - Community Engine: Version: 18.09.6 API version: 1.39 (minimum version 1.12) Go version: go1.10.8 Git commit: 481bc77 Built: Sat May 4 02:02:43 2019 OS/Arch: linux/amd64 Experimental: false
3.3) 安裝Docker Compose
Docker Compose 是 Docker 容器進行編排的工具,定義和運行多容器的應用,能夠一條命令啓動多個容器。 安裝 epel-release [root@harbor-node ~]# yum install epel-release 安裝 python-pip [root@harbor-node ~]# yum install -y python-pip 安裝 docker-compose [root@harbor-node ~]# pip install docker-compose ......... Successfully installed asn1crypto-0.24.0 bcrypt-3.1.6 cached-property-1.5.1 certifi-2019.3.9 cffi-1.12.3 chardet-3.0.4 cryptography-2.6.1 docker-3.7.2 docker-compose-1.24.0 docker-pycreds-0.4.0 dockerpty-0.4.1 docopt-0.6.2 enum34-1.1.6 functools32-3.2.3.post2 idna-2.7 jsonschema-2.6.0 paramiko-2.4.2 pyasn1-0.4.5 pycparser-2.19 pynacl-1.3.0 requests-2.20.1 texttable-0.9.1 urllib3-1.24.3 websocket-client-0.56.0 You are using pip version 8.1.2, however version 19.1.1 is available.

You should consider upgrading via the 'pip install --upgrade pip' command. docker-compose==1.24.0 安裝 git [root@harbor-node ~]# yum install git
3.4) 爲Docker配置加速器, 方便經過國內鏡像服務器快速拉取Docker Hub提供的鏡像
[root@harbor-node ~]# mkdir -p /etc/docker [root@harbor-node ~]# cat /etc/docker/daemon.json { "registry-mirrors": ["https://v5d7kh0f.mirror.aliyuncs.com"] }
3.5) 下載Harbor安裝包,配置Harbor
到Harbor的GitHub倉庫的Release頁面, 下載最新的在線安裝包(若是下載不了, 請從這裏下載百度網盤Harbor 提取碼:xu3j)
這裏分爲在線和離線的版本,我下載的是1.8.0在線的版本
[root@harbor-node ~]# ll harbor-online-installer-v1.8.0.tgz -rw-r--r-- 1 root root 7954 May 26 22:45 harbor-online-installer-v1.8.0.tgz [root@harbor-node ~]# tar -zvxf harbor-online-installer-v1.8.0.tgz [root@harbor-node ~]# cd harbor [root@harbor-node harbor]# ls harbor.yml install.sh LICENSE prepare 下載下來以後解壓縮,目錄下會有harbor.yaml (新版本是.yaml文件,以前版本是.conf 或者 .cfg文件),就是Harbor的配置文件了。 [root@harbor-node harbor]# cp harbor.yml harbor.yml.bak [root@harbor-node harbor]# vim harbor.yml [root@harbor-node harbor]# cat harbor.yml |grep -v "#"|grep -v "^$" hostname: 172.16.60.213 http: port: 80 harbor_admin_password: kevin@BO123 database: password: root123 data_volume: /data clair: updaters_interval: 12 http_proxy: https_proxy: no_proxy: 127.0.0.1,localhost,core,registry jobservice: max_job_workers: 10 chart: absolute_url: disabled log: level: info rotate_count: 50 rotate_size: 200M location: /var/log/harbor _version: 1.8.0 配置解釋 hostname: 修改爲Harbao部署機自身的ip地址 db_password: 這是postgresql數據庫root密碼 harbor_admin_password: harbor初始管理員密碼爲Harbor12345, 這裏最好修改爲本身的密碼,默認密碼至少8位,最好是大小寫、數字和特殊字符。 配置完Harbor以後,接着進行安裝啓動Harbor,Harbor目錄下有一個install.sh, 執行它來進行安裝 [root@harbor-node harbor]# ./install.sh ........... ........... ✔ ----Harbor has been installed and started successfully.---- Now you should be able to visit the admin portal at http://172.16.60.213. For more details, please visit https://github.com/goharbor/harbor . 安裝完成後,會發現解壓目錄harbor下面多了一個docker-compose.yml文件,裏面包含了harbor依賴的鏡像和對應容器建立的信息 查看harbor對應容器信息(還能夠執行"docker images"和"docker ps"查看harbor的鏡像和容器狀況) [root@harbor-node harbor]# docker-compose ps #"注意docker-compose"命令只能在當前harbor目錄下使用(由於該目錄下有harbor配置文件) Name Command State Ports --------------------------------------------------------------------------------------------- harbor-core /harbor/start.sh Up (healthy) harbor-db /entrypoint.sh postgres Up (healthy) 5432/tcp harbor-jobservice /harbor/start.sh Up harbor-log /bin/sh -c /usr/local/bin/ ...

Harbor 服務的關閉和啓動
1) Harbor的日誌路徑:var/log/harbor [root@harbor-node harbor]# cat harbor.yml|grep log log: # Log files are rotated log_rotate_count times before being removed. If count is 0, old versions are removed rather than rotated. # Log files are rotated only if they grow bigger than log_rotate_size bytes.

-> 登陸Harbor web界面,在"系統管理"->"配置管理"->"認證模式"->"容許自注冊"這一項的對勾去掉,則登陸的時候就不會有"用戶註冊"這一功能了。
-> 能夠在"配置管理"這一項進行認證模式,郵箱,標籤等設置。
3.6) 使用Harbor私有倉庫
3.6.1)harbor的login登陸
1)在harbor遠程別的客戶機上登陸 [root@docker-client ~]# docker login 172.16.60.213 Username: admin Password: Error response from daemon: Get https://172.16.60.213/v1/users/: dial tcp 172.16.60.213:443: connect: connection refused 在進行harbor登陸或上傳代碼時,會報出上面錯誤! 這是由於docker1.3.2版本開始默認docker registry使用的是https,而Harbor默認設置的是http方式而不是https,因此當執行用docker login、pull、push等 命令操做非https的docker regsitry的時就會報錯。 解決辦法: 以下,在/etc/docker/daemon.json文件裏添加"insecure-registries"配置。(若是還不行,能夠嘗試將下面添加的地址由"172.16.60.213"改成"http://172.16.60.213") [root@docker-client ~]# vim /etc/docker/daemon.json { "insecure-registries": [ "172.16.60.213" ] } 而後重啓docker服務 [root@docker-client ~]# systemctl restart docker 接着再次驗證harbor登陸,發現就能登陸上了 [root@docker-client ~]# docker login 172.16.60.213 #或者直接執行"docker login -u admin -p kevin@BO123 172.16.60.213"命令登錄 Username: admin Password: Login Succeeded [root@docker-client ~]# 2)若是是在harbor本機登陸,出現上面的報錯: [root@harbor-node harbor]# docker login 172.16.60.213 Username: admin Password: Error response from daemon: Get https://172.16.60.213/v1/users/: dial tcp 172.16.60.213:443: connect: connection refused 解決辦法: 在/etc/docker/daemon.json 文件裏添加"insecure-registries"配置 (第一行是以前添加的docker加速配置),注意兩行之間有一個","逗號隔開 [root@harbor-node harbor]# vim /etc/docker/daemon.json { "registry-mirrors": ["https://v5d7kh0f.mirror.aliyuncs.com"], "insecure-registries": ["172.16.60.213"] } 修改事後重啓docker, 而後重啓Harbor服務 [root@harbor-node harbor]# systemctl restart docker [root@harbor-node harbor]# docker-compose stop [root@harbor-node harbor]# docker-compose start 而後再測試再harbor本機登陸 [root@harbor-node harbor]# docker login 172.16.60.213 Username: admin Password: WARNING!

注意事項總結:
harbor支持http和https,但若是使用http的話,在拉取鏡像的時候,會拋出倉庫不受信任的異常。
須要在全部的docker客戶端的docker配置文件/etc/docker/daemon.json中添加以下配置:
{ "insecure-registries": ["https://*.*.*.*"] }
若是使用自簽名的https證書,仍然會提示證書不受信任的問題。須要將自簽名的ca證書發送到全部的docker客戶端的指定目錄。
關於使用自簽名證書配置harbor的具體過程能夠參考: https://github.com/goharbor/harbor/blob/master/docs/configure_https.md
3.6.2)harbor倉庫的使用
#鏡像打標籤的命令 # docker tag 鏡像名:標籤 私服地址/倉庫項目名/鏡像名:標籤 #推送到私服的命令 #docker push 私服地址/倉庫項目名/鏡像名:標籤 #從私服拉取鏡像的命令 #docker pull 私服地址/倉庫項目名/鏡像名:標籤
首先在Harbor web界面裏最好建立一個本身須要的"項目" (或者使用默認的"library"項目),項目公開和私有:
- Public: 全部用戶對於公開項目都有讀權限,這種方式對於你想把一些倉庫分享給其餘人的時候,是很是方便的.
- Private: 私有項目只能被有特定用戶權限的人去訪問。這種方式對於內部團隊來講共享也是比較方便的
好比建立一個公開項目"kevin_bo",點擊進去能夠看到推送鏡像的信息提示
而後就能夠在Harbor服務器的終端命令行裏進行鏡像推送到Harbor倉庫的操做了:
在進行harbor鏡像推送和拉取操做前,須要事先login登陸到harbor倉庫裏,這樣纔有harbor鏡像的推送和拉取的權限!! [root@harbor-node ~]# docker login 172.16.60.213 Authenticating with existing credentials... WARNING!

而後登陸到Harbor web 界面裏,就能夠看到"kevin_bo"項目裏就有了上面推送的兩個鏡像了,點擊到對應的鏡像了,還能夠對鏡像進行打標籤,複製鏡像等操做:
好比將"kevin_bo"項目裏上面的kevin_bo/goharbor/harbor-core鏡像複製到"library"項目裏
而後到"library"項目裏就能看到上面從"kevin_bo"項目裏複製過來的鏡像了
注意: harbor私倉的相關容器映射到主機的volumes數據卷的空間要有保證,最好是單獨的分區空間。
上面測試harbor容器經過volumes映射到主機的目錄是/data, 能夠到這裏查看harbor推送的鏡像:
[root@harbor-node repositories]# pwd /data/registry/docker/registry/v2/repositories 能夠查看兩個"項目" [root@harbor-node repositories]# ll total 0 drwxr-xr-x 4 10000 10000 42 May 27 14:01 kevin_bo drwxr-xr-x 3 10000 10000 27 May 27 14:08 library [root@harbor-node repositories]# ll kevin_bo/ total 0 drwxr-xr-x 3 10000 10000 25 May 27 14:01 goharbor drwxr-xr-x 5 10000 10000 55 May 27 13:58 redis-photon [root@harbor-node repositories]# ll library/ total 0 drwxr-xr-x 3 10000 10000 21 May 27 14:08 172.16.60.213 [root@harbor-node repositories]# ll library/172.16.60.213/ total 0 drwxr-xr-x 3 10000 10000 25 May 27 14:08 library

能夠在登陸Harbor web界面以後,修改相關用戶的密碼。在不一樣用戶帳號下建立項目,以及推送和拉取harbor鏡像操做。
3.6.3)Harbor的https證書啓用
經過上面可知,harbor默認安裝後採用的是http方式,後面使用的時候可能會發現不少不方面。由於Docker客戶端登陸harbor進行鏡像推送或拉取時默認是https方式!因此http方式下,須要在每一臺harbor客戶端機器上都要設置"insecure-registries", 感受很麻煩!因此最好仍是將harbor默認的http方式改成https方式!另外,從安全角度考慮,容器的倉庫在生產環境中每每也是須要被設定爲https的方式,而harbor將這些證書的建立和設定都進行了簡單的集成,下面來看一下在harbor下如何使用https的方式。配置記錄以下:
在建立證書以前,爲了方面驗證,須要將前面在客戶端機器上/etc/docker/daemon.json文件裏添加"insecure-registries"配置刪除 [root@docker-client ~]# vim /etc/docker/daemon.json {} [root@docker-client ~]# rm -rf /root/.docker 重啓docker服務 [root@docker-client ~]# systemctl restart docker 將harbor部署機自身的/etc/docker/daemon.json文件裏添加"insecure-registries"配置也刪除 [root@harbor-node ~]# vim /etc/docker/daemon.json { "registry-mirrors": ["https://v5d7kh0f.mirror.aliyuncs.com"] } [root@harbor-node ~]# rm -rf /root/.docker 而後重啓docker和docker-compose [root@harbor-node ~]# systemctl restart docker [root@harbor-node ~]# docker-compose down -t [root@harbor-node ~]# docker-compose up -d 1)建立CA [root@harbor-node harbor]# pwd /root/harbor [root@harbor-node harbor]# mkdir ssl [root@harbor-node harbor]# cd ssl/ [root@harbor-node ssl]# pwd /root/harbor/ssl [root@harbor-node ssl]# openssl req -newkey rsa:4096 -nodes -sha256 -keyout ca.key -x509 -days 365 -out ca.crt Generating a 4096 bit RSA private key ......................................++ ...................................................................................................................................................................................................................................................................++ writing new private key to 'ca.key' ----- You are about to be asked to enter information that will be incorporated into your certificate request.

[root@client 172.16.60.213]# docker login -u admin -p kevin@Bo1987 172.16.60.213:443 Login Succeeded [root@client 172.16.60.213]# cat /root/.docker/config.json { "auths": { "172.16.60.213:443": { "auth": "YWRtaW46a2V2aW5AQk9CTzEyMw==" } } } 上面是使用443端口登錄harbor倉庫是正常的,若是此時使用80端口登錄,則出現以下報錯: [root@client 172.16.60.213]# docker login -u admin -p kevin@Bo1987 172.16.60.213 Error response from daemon: Missing client certificate 172.16.60.213.cert for key 172.16.60.213.key 因此在客戶端就使用443端口來登錄harbor倉庫了!
3.6.4) Harbor私倉的高可用
經過三個harbor完成高可用部署,前面經過負載均衡器對外提供服務。共享數據庫與緩存。結構以下 :
還有一種比較簡單的方法:部署2臺harbor服務器,配置部署同樣,實現原理:
建立docker harbor主主複製就是在兩個harbor私倉的web界面裏建立相互之間的鏡像同步關係,同步關係能夠選擇相同用戶或不一樣用戶之間。這樣就能夠保證harbor私倉的雙機熱備關係了。即:1) "系統管理"->"倉庫管理"->"新建目標", 填寫對端harbor信息2) "系統管理"->"同步管理"->"新建規則", 規則裏會引用目的Registry,也就是上面一步建立的目標。同步模式有Push-based,Pull-based;觸發模式有自動和定時。
