Question

我正在尝试从官方jenkins git repo构建jenkins docker图像： https://github.com/jenkinsci/docker。

但是当我尝试使用docker run -it -dP jenkins运行图像的容器时，它立即退出，当我检查docker日志时，我收到以下错误：

: invalid option

我读到错误可能是因为tini的pid不是1.我查看了文档并看到如果我们执行以下操作，它应该解决问题。将-s参数传递给Tini（tini -s - ...）设置环境变量TINI_SUBREAPER（例如，导出TINI_SUBREAPER =）。

但它没有解决任何问题。

以下是使用docker build -t jenkins .构建的Dockerfile的确切副本：

问题在于docker版本。我的Docker版本很旧。不确定哪个命令不受支持，但新的docker构建了dockerfile。
