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.
