The Dockerfile uses a multi-stage build to first build the Next.js app in one image, and then serve it using a lightweight Node.js image in a separate stage.

Before you begin, ensure that you have the following installed on your local machine:

• Docker

To build the Docker image and run the Next.js app inside a Docker container, follow these steps:

• Clone this repository to your local machine.
• Navigate to the root directory of the cloned repository in a terminal window.
• Run the following command to build the Docker image:

docker build -t techtime .

This will build the Docker image using the Dockerfile in the current directory and tag it with the name techtime.

• Once the build is complete, you can run the Docker container using the following command:

docker run 3000:3000 techtime

This command runs a Docker container using the "techtime" image and performs the following actions:

• --rm: Automatically removes the container when it exits.
• -it: Starts an interactive terminal session in the container.
• -p 3000:3000: Maps port 3000 of the container to port 3000 of the host machine. This is necessary for accessing the application running inside the container. techtime: Specifies the name of the Docker image to use for the container.
