解决：

登录 Harbor ：确保你已经使用 docker login 命令登录到 Harbor 。如果你还没有 Harbor 账户，你需要先注册一个。
检查镜像名称：确认 alpine-java 镜像名称是否正确，并且该镜像存在于 Docker Hub 上。如果名称错误或镜像不存在，你需要使用正确的镜像名称或查找是否存在替代的镜像。
检查 Docker 配置：如果你的网络环境需要通过代理访问外部资源，确保 Docker 配置正确地设置了代理。
检查网络连接：确保你的网络连接稳定，并且可以访问 Harbor 。
检查 Harbor 状态：访问Harbor 状态页面
来查看是否有已知的服务中断或维护。
使用国内镜像源：如果你在中国大陆或网络连接不稳定的地区，配置 Docker 使用镜像加速器可以提高下载速度并减少超时的可能性。
检查 Docker 守护进程日志：查看 Docker 守护进程的日志，可能会提供更多关于错误的详细信息。
升级 Docker 和客户端：确保你使用的是最新版本的 Docker 和 Docker 客户端，因为旧版本可能存在已知的 bug 或性能问题。
检查权限：如果你尝试访问的是私有仓库或私有镜像，确保你有足够的权限。
使用正确的 Harbor URL：如果你使用的是私有仓库或第三方仓库，确保在拉取镜像时使用了正确的 URL。
