How can I use containers for my software builds?

Using containers can help you create consistent and reproducible builds. You can use tools like Docker to package your application and its dependencies into a container.

What are the benefits of using Docker for builds?

Docker allows for isolation of environments, faster build times, and easier collaboration across teams. It also simplifies dependency management.

Can you give me an example of a Dockerfile for a Node.js application?

Sure! Here's a simple Dockerfile:

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

This sets up a Node.js environment for your app.

How do I run my container after building it?

You can run your container using the command docker run -p 3000:3000 your-image-name. This maps port 3000 of the container to port 3000 on your host.
