Harbor 开机自启遇到的问题

Harbor 是一个企业级的 Docker 私有仓库项目，使用 docker-compose 启动时，它本身由多个 Docker Containers 组成，通过 docker-compose 管理 containers 之间的依赖关系。

安装

安装参见官方文档：Harbor - Installation and Configuration Guide，
修改 harbor.yml 时，需要注意的有：

1. 使用 https 时，要自己生成证书，然后在 harbor.yml 里配置好证书的路径。
   • 客户端也需要安装你生成的这个证书，否则会报错。（所以证书要做好备份）
   • 详见 Docker - Use self-signed certificates
2. data_volume 可以指定为 /data/harbor，然后要定期备份这个文件夹。（或者直接在新机器上装个 harbor，用 harbor 自带的仓库复制功能做定期备份。）
3. 企业的话，可能还需要配置 ldap 集成验证。

然后 sudo ./install.sh 安装 harbor（貌似必须用 sudo，因为生成出来的配置文件的 owner 都是 root，而且权限设得很严格。）
安装完成后会自动启动 harbor.

自动启动

查看 harbor 目录下的 docker-compose.yml 会发现，所有的 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
    # ......

这表示所有的容器在意外关闭后都会自动重启，比如 docker 重启或服务器重启。（手动 stop 不会自动重启）

但是我在手动运行 docker-compose up -d，然后重启服务器后，发现有几个 container 并没有自动重启：

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

可以看到下列五个容器都处于 Exited 状态：

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

搜索发现有人提过这个 issue: https://github.com/goharbor/harbor/issues/7008

于是尝试将 harbor 配成 systemd 的 service，添加配置文件 /usr/lib/systemd/system/harbor.service，内容如下：

[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 }} 换成自己的 harbor 安装路径。
还有 docker-compose 的绝对路径，请通过 which docker-compose 查看。

然后启动该项服务：

sudo systemctl enable harbor
sudo systemctl start harbor

现在查看下 harbor.service 的情况：

● harbor.service - Harbor

重启服务器再确认，发现 harbor 容器组终于全部 up 了：
