将参数传递给docker run命令

我正在运行以下命令启动Jekyll与我的本地签出Jekyll网站：

docker run -p 4000:4000 --volume=$PWD:/srv/jekyll \ -it jekyll/jekyll:$JEKYLL_VERSION jekyll serve 

这工作得很好。 但是，当我通过它--baseurl参数是这样的：

 docker run -p 4000:4000 --volume=$PWD:/srv/jekyll \ -it jekyll/jekyll:$JEKYLL_VERSION jekyll serve --baseurl '' 

一切都运行良好，直到它到了这一点：

 > docker run -p 4000:4000 --volume=$PWD:/srv/jekyll -it jekyll/jekyll:$JEKYLL_VERSION jekyll serve --baseurl '' Warning: the running version of Bundler (1.15.2) is older than the version that created the lockfile (1.15.3). We suggest you upgrade to the latest version of Bundler by running `gem install bundler`.

为什么会发生这种情况，如何将--basepath参数传递给--basepath命令？ 似乎我正在做一些与码头工人有关的问题，这是我所熟悉的。

谢谢！

根据https://docs.docker.com/v1.7/reference/run/#env-environment-variables上的文档，您可以用docker run命令和-e参数传递它。

这是我在一个简单的运行脚本中测试的：

 # Start Jekyll and watch for changes docker run --rm -it \ -e JEKYLL_ENV=production \ --volume=/$(pwd):/srv/jekyll \ --publish 4000:4000 \ $DOCKER_IMAGE_NAME 

图片简单地是格雷厄姆/ jekyll。 我尝试在上面的docker run命令中添加-e BASEURL =“”\。 但是，我发现如果在_config.yml中设置了baseurl，那么设置就会胜过环境设置。
