standard_init_linux.go:195:exec用户进程导致“没有这样的文件或目录”

问题描述 投票:0回答:1

我从Docker hub(https://github.com/docker-library/wordpress/tree/c919246e5ce9a94cb0ad275072d34563ef2ecc46/php7.2/apache)中提取了wordpress Dockerfile和Docker条目,并使用AWS代码构建构建了映像。它将映像推送到AWS ECR,并在ECS上进行部署。部署失败,代码为standard_init_linux.go:195:exec用户进程导致“没有这样的文件或目录”

我尝试了一些修复,但没有一个正在工作并抛出相同的问题1.我将#!/ bin / bash更改为#!/ bin / sh当我在Ec2上本地进行docker构建时,部署工作正常。

任何帮助将受到高度赞赏

您是否尝试过如下使用显式路径? ENTRYPOINT ["/usr/local/bin/docker-entrypoint.sh"]
