TrainWithShubham is the channel created with the idea of bridging the gap between academic learning and the corporate world. We all know that schools and universities don't necessarily prepare us for the corporate world. There's a huge difference between what's going on in the industry and what's being taught to us in schools and colleges.
We are here to prepare you for the world with content based on my industry knowledge & experiences as a developer.

y cant we write CMD ["npm start"] instead of CMD ["npm","start"] as both are passing a string of values Docker need a string to identify the command to run right?

Frontend Dockerfile ko build krk image bnate time "npm i" vale step me stuck ho raha hai, then usk baad pura terminal unresponsive horaha hai, then i have to restart the ec2 instance, and if i try to build frontend image i am facing same issue i.e. front end image bnate time getting stuck in "npm i" step. Backend ki image bnate time it does not give this behaviour. I have EC2 AWS instance (free tier), usme volume is 8 GB,.kya mujhe apna volume increase krna chahiye ? if yes, then will it create a cost? Please suggest
