1. 介绍

Harbor 是一个开源的企业级 Docker 镜像仓库，提供镜像存储、访问控制、安全扫描等功能。使用 Docker Compose 启动 Harbor 时，您可以指定一个自定义网络，以便管理容器之间的网络通信。在本示例中，我们将创建一个名为 harbor 的网络，并为其指定子网 172.18.0.0/16。

2. 创建 docker-compose.yml 文件

以下是一个包含 Harbor 服务和指定网络的 docker-compose.yml 配置文件：

3. 关键配置说明

• networks 部分:

  • harbor: 定义了一个自定义的 Docker 网络。
  • external: false: 表示该网络是 Docker Compose 创建的本地网络，而不是外部已存在的网络。
  • ipam: 配置了 IP 地址管理（IPAM）参数，用来指定子网 172.18.0.0/16。

• services 部分:

  • 每个 Harbor 服务（如 postgresql、core、registryctl 等）都被配置为连接到 harbor 网络。
  • depends_on 关键字用来指定容器之间的启动顺序，例如，core 服务需要在 postgresql 启动后启动。

• ports 部分:

  • proxy 服务通过 ports 关键字将容器的端口映射到主机

端口，以便外部可以访问 Harbor 服务。

4. 启动 Harbor

在包含 docker-compose.yml 文件的目录中，使用以下命令启动 Harbor：

docker-compose up -d

这将启动所有 Harbor 服务并连接到您定义的自定义网络 harbor。

5. 查看容器状态

您可以使用以下命令检查 Harbor 服务容器的运行状态：

docker-compose ps

6. 停止 Harbor

如果需要停止 Harbor 服务，可以使用以下命令：

docker-compose down

这样，您就成功配置并启动了一个带有自定义网络的 Harbor Docker Compose 环境。如果您有其他问题或需要进一步调整配置，随时可以提问！
