java - 构建 Jhipster 项目以在 kubernetes 上部署时出错

问题描述

我在构建 jhipster 项目以部署在 Kubernetes 上时遇到问题。我正在关注这个链接。

以下是我的日志：

我对 docker/kubernetes 了解不多。

Update-1docker images我按照答案中的建议 尝试了命令。它以前可以工作，但不是不能工作。docker images运行命令时出现以下错误。

error during connect: Get https://192.168.99.100:2376/v1.37/images/json: dial tcp 192.168.99.100:2376: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

解决方案

您需要安装并运行 Docker 才能为应用程序构建 Docker 映像。该错误表明它无法连接到正在运行的 Docker 实例。

在 Windows 上，由于缺少命名管道，您可能必须调整 Docker 的设置并打开“Expose daemon on tcp://localhost:2375 without TLS”。（来源）
