Harbor 開機自啓遇到的問題

Harbor 是一個企業級的 Docker 私有倉庫項目，它自己由多個 Docker Containers 組成，經過 docker-compose 管理 containers 之間的依賴關係。

安裝

安裝參見官方文檔：Harbor - Installation and Configuration Guide，
修改 harbor.yml 時，須要注意的有：

1. 使用 https 時，要本身生成證書，而後在 harbor.yml 裏配置好證書的路徑。
   • 客戶端也須要安裝你生成的這個證書，不然會報錯。（因此證書要作好備份）
   • 詳見 Docker - Use self-signed certificates
2. data_volume 能夠指定爲 /data/harbor，而後要按期備份這個文件夾。（或者直接在新機器上裝個 harbor，用 harbor 自帶的倉庫複製功能作按期備份。）
3. 企業的話，可能還須要配置 ldap 集成驗證。

而後 sudo ./install.sh 安裝 harbor（貌似必須用 sudo，由於生成出來的配置文件的 owner 都是 root，並且權限設得很嚴格。）
安裝完成後會自動啓動 harbor.

自動啓動

查看 harbor 目錄下的 docker-compose.yml 會發現，全部的 containers 都配置了 restart: always：

version: '2.3'
services:
  log:
    image: goharbor/harbor-log:v1.8.1
    container_name: harbor-log
    restart: always
    dns_search: .
    # ......

  registry:
    image: goharbor/registry-photon:v2.7.1-patch-2819-v1.8.1
    container_name: registry
    restart: always
    # ......

這表示全部的容器在意外關閉後都會自動重啓，好比 docker 重啓或服務器重啓。（手動 stop 不會自動重啓）

可是我在手動運行 docker-compose up -d，而後重啓服務器後，發現有幾個 container 並無自動重啓：

[ryan@ryan-pc ~]$ docker ps -a

能夠看到下列五個容器都處於 Exited 狀態：

1. goharbor/nginx-photon:v1.8.1
2. goharbor/harbor-portal:v1.8.1
3. goharbor/harbor-jobservice:v1.8.1
4. goharbor/redis-photon:v1.8.1
5. goharbor/registry-photon:v2.7.1-patch-2819-v1.8.1

搜索發現有人提過這個 issue: https://github.com/goharbor/harbor/issues/7008

因而嘗試將 harbor 配成 systemd 的 service，添加配置文件 /usr/lib/systemd/system/harbor.service，內容以下：

[Unit]
Description=Harbor
After=docker.service systemd-networkd.service systemd-resolved.service
Requires=docker.service
Documentation=http://github.com/vmware/harbor

[Service]
Type=simple
Restart=on-failure
RestartSec=5
ExecStart=/usr/local/bin/docker-compose -f {{ harbor_install_path }}/harbor/docker-compose.yml up
ExecStop=/usr/local/bin/docker-compose -f {{ harbor_install_path }}/harbor/docker-compose.yml down

[Install]
WantedBy=multi-user.target

其中 {{ harbor_install_path }} 換成本身的 harbor 安裝路徑。
還有 docker-compose 的絕對路徑，請經過 which docker-compose 查看。

而後啓動該項服務：

sudo systemctl enable harbor
sudo systemctl start harbor

如今查看下 harbor.service 的狀況：

● harbor.service - Harbor

重啓再看，發現 harbor 容器組終於所有 up 了：
