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

代码语言:javascript复制
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:

goharbor/nginx-photon:v1.8.1
goharbor/harbor-portal:v1.8.1
goharbor/harbor-jobservice:v1.8.1

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:

代码语言:javascript复制
[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:

代码语言:javascript复制
sudo systemctl enable harbor
sudo systemctl start harbor

现在查看下 harbor.service 的情况:

重启服务器再确认,发现 harbor 容器组终于全部 up 了:
