[英]How to access to a folder host via a docker container?
I'm actually stuck with the problem of a shared file.我实际上遇到了共享文件的问题。
I want to access my host folders so I did something like this in my Jenkinsfile :我想访问我的主机文件夹,所以我在我的 Jenkinsfile 中做了这样的事情:
sh "sudo docker run -d -it -p 16000:16000 -v /PATH/TO/MY/HOST/FOLDER/:/var/tmp --name botvolume MY_IMAGE"
And in my scala class I'm trying to get all the folders by using :在我的 Scala 课程中,我尝试使用以下方法获取所有文件夹:
val folders: Array[File] = new File("/PATH/TO/MY/HOST/FOLDER/")
.listFiles
.filter(_.isDirectory)
But it's doesn't work, it returns a size equal to 0.但它不起作用,它返回一个等于 0 的大小。
I read the docker volumes documentation我阅读了 docker 卷文档
Can someone help me?有人能帮我吗?
Inside the container the volume path is /var/tmp
在容器内,卷路径是
/var/tmp
Then your code should be :那么你的代码应该是:
val folders: Array[File] = new File("/var/tmp/")
.listFiles
.filter(_.isDirectory)
You can find the detail on the Docker volume bind syntax on the link you provided:您可以在您提供的链接上找到有关 Docker 卷绑定语法的详细信息:
-v or --volume: Consists of three fields, separated by colon characters (:) . -v 或 --volume:由三个字段组成,以冒号(:) 分隔。 The fields must be in the correct order, and the meaning of each field is not immediately obvious.
字段必须按正确的顺序排列,每个字段的含义不是很明显。
