mount

Original question: How to use the VOLUME instruction in Dockerfile? The actual question I want to solve is -- how to mount host volumes into docker containers in Dockerfile during build, i.e., having the docker run -v /export:/export capability during docker build . The reason behind it, for me, is when building things in Docker, I don't want those ( apt-get install ) caches locked in a single docker, but to share/reuse them. That's the main reason I'm asking about this question. Latest Update: Before docker v18.09, the correct answer should be the one that starts with: There is a way to mount

NFS ( Network File System ) is basically developed for sharing of files and folders between Linux / Unix systems by Sun Microsystems in 1980 . It allows you to mount your local file systems over a network and remote hosts to interact with them as they are mounted locally on the same system. With the help of NFS , we can set up file sharing between Unix to Linux system and Linux to Unix system. Setup NFS Server and NFS Client in Linux Benefits of NFS NFS allows local access to remote files. It uses standard client / server architecture for file sharing between all * nix based machines. With NFS

I am trying to mount a host directory into a Docker container so that any updates done on the host is reflected into the Docker containers. Where am I doing something wrong. Here is what I did: kishore$ cat Dockerfile FROM ubuntu:trusty RUN apt-get update RUN apt-get -y install git curl vim CMD ["/bin/bash"] WORKDIR /test_container VOLUME ["/test_container"] kishore$ tree . ├── Dockerfile └── main_folder ├── tfile1.txt ├── tfile2.txt ├── tfile3.txt └── tfile4.txt 1 directory, 5 files kishore$ pwd /Users/kishore/tdock kishore$ docker build --tag=k3_s3:latest .

出现的意义：其 实$mount()函数和Vue的el功能是一样的，将组件挂载到DOM元素之上，不同的是挂载的时机是不一样的。 el:是在Vue的实例创建过程中的create()钩子函数中进行初始化的 $mount():是手动挂起，挂载的时机是在及调用他的时候触发的 参数形式： 一种是绑定DOM的id引用，另一种是DOM元素 来源： https://blog.csdn.net/txwsmsm7023_/article/details/98737183
