Have you had experience working with Docker for containerizing applications?

Yes, experience with Docker for containerizing applications typically includes:

• Creating a Dockerfile to describe the application image.
• Building the image using docker build.
• Running containers with docker run.
• Using Docker Compose for orchestrating multiple services.

A simple Dockerfile example for a Node.js application:

FROM node:16
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
CMD ["node", "index.js"]

This allows running the application in an isolated environment, simplifying deployment and testing.
