How do I deploy my application using Docker?

To deploy your application with Docker, you first need to create a Dockerfile that defines your app's environment.

What should I include in the Dockerfile?

Your Dockerfile should include the base image, any dependencies, and the commands to build and run your application.

Can you give me an example of a simple Dockerfile?

Sure! Here's a basic example:

FROM node:14
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
CMD ["node", "app.js"]

This sets up a Node.js application.

How do I build and run the Docker container?

You can build your Docker image with docker build -t myapp . and run it using docker run -p 3000:3000 myapp.
