How to bind any folder from local system to any container to access it. This will just create a link to folder in place of copying all the data, So in this away we can avoid copy same data in multiple place and same the memory
[root@ip-172-31-93-105 ~]# mkdir bind
[root@ip-172-31-93-105 ~]# ld
ld: no input files
[root@ip-172-31-93-105 ~]# ls
bind
[root@ip-172-31-93-105 ~]# cd bind/
[root@ip-172-31-93-105 bind]# vi index.html
[root@ip-172-31-93-105 bind]# cat index.html
<html>
<head>
<title>test</title>
</head>
<body>

if you change any thing in local system same will reflect in container also
Note:-
In place of this command
docker container run -it -v /root/bind:/tmp/test/ ubuntu:14.04 bash
You can also use
docker container run -it --mount type=bind,source= /root/bind,target=/tmp/test/ ubuntu:14.04 bash
