+# UNDERSTANDING VOLUMES:
+
+To make the storage persistent in docker. 
+
+
+
+*   docker run -it --name busybox_1 -v /data busybox
+
+    // -v is used to add the volume
+
+*   cd data
+*   ls
+*   touch test.txt
+*   exit
+*   docker run -t --name busybox_2 busybox
+*   ls
+*   //Even though the image is of same image, the file is not being displayed
+*   exit
+*   docker rm busybox_2
+*   docker run -it --name busybox_2 --volume-from busybox_1 busybox
+*   ls
+
+    //Now the file is displayed inside the data folder.
+
+
+This is how persistent storage is created in the docker. So 2 APIs in two container communicating with each other use volumes to share the data.
