# Docker Volume Simple Practical Example

### Step 1 : Create one directory.

mkdir app

### Step 2: Create one index.js file.

vim index.js

### Step 3: Pull the node image.

docker run -it node:latest

### Step 4: Check the container.

docker container ls -a

### Step 5: Check the working directory where you have created the app directory and copy the path.

pwd

### Step 6: Mount the container into the application. 

docker run -it -v /home/deepak/app:/home/app node bash

/home/deepak/app :- This is the local machine path where the application directory is present.

/home/app :- This is the mount directory path, which means the mount container location.

node :- This is the image.

bash :- This is the bash terminal I want to open for the next command.

### Step 7: Checking the bash terminal is user

uname

### Step 8: Checking if the home directory is present or not. 

ls

***Refer step 9 screenshot.***

### Step 9: Go to the home directory.

cd home

### Step 10: Checking files under home directory

ls

app :- This is our directory.

node :- This is our image.

***Refer step 9 screenshot.***

### Step 11: Go into the app directory and check the index. js

cd app

cat index.js

(You will get the code of the index.js file.)

***Refer step 9 screenshot.***

### Step 12: Install Nodemon to run the index.js file.

npm install -g nodemon

### Step 13: Run the index.js application. 

nodemon index.js

### Step 14: Open another terminal, try to edit the local index.js file, and save. All changes will apply to the running environment.
