如何将文件复制到停止的docker容器

我正在docker容器中运行elasticsearch.

在为ssl和shield配置elasticsearch时,我的elasticsearch.yml文件被非法输入,TAB而不是a space.
现在我的docker容器没有启动并出现以下错误:

{1.4.4}: Setup Failed ...
- SettingsException[Failed to load settings from [file:/elasticsearch/config/elasticsearch.yml]]
         IOException[Tabs are illegal in YAML.  Did you mean to use whitespace character instead?]

如何elasticsearch.yml在不丢失数据或替换elasticsearch.yml现有容器中的文件的情况下编辑或替换它？

您可以将文件复制出来,然后将其复制回容器(即使容器已停止)docker cp $cont_name:/path/in/container /path/on/host,然后复制出来然后复制出来docker cp /path/on/host $cont_name:/path/in/container.
