docker - Dockerfile 构建成功但容器无法运行

问题描述

我为 varnish plus 写了一个 dockerfile。Docker build 成功执行，但在 docker run 上说/bin/sh: 1: ./init: not found not found.我在 dockerfile 上缺少什么？

我正在尝试为 Kubernetes varnish 部署构建自定义 docker 构建。

我尝试了另一个参数，如 CMD["sh", "init"] 然后我得到 ./start-agent 失败。如果我将 sh 放在 /etc/default/varnish 错误中找不到的任何地方。也得到了初始化完成错误，它说期待“然后”。我以相同的方式安装在裸机上，但无法在 docker 容器上运行。

CMD ./init

我的 init.sh 文件位于与 dockerfile 相同位置的脚本文件夹下。

解决方案

Varnish Software 有一个官方的Varnish Cache Plus Docker 镜像。如果您有订阅，我怀疑您有，您可以通过 support@varnish-software.com 获得支持的帮助。

支持人员可以查看您的Dockerfile信息并为您提供建议，但他们也可以解释您如何使用官方图像来完成工作，而无需Dockerfile自己维护。
