Why do we use a multi-stage build in Docker for Vue apps?

Multi-stage builds let you separate the build environment from the final image. This keeps the final image small and only includes what is needed to run the app.

beginner

What command do you run to build a Docker image for your Vue app?

You run docker build -t your-image-name . in the folder with your Dockerfile to create the image.

How do you serve a built Vue app inside a Docker container?

After building the Vue app, you use a lightweight web server like Nginx inside the container to serve the static files.

What is the first step in deploying a Vue app with Docker?

A Run the Vue app locally

B Install Vue CLI globally

C Push code to GitHub

D Create a Dockerfile with build instructions

You start by creating a Dockerfile that tells Docker how to build your app image.

Which Docker feature helps keep the final image small when deploying Vue apps?

A Docker volumes

B Multi-stage builds

C Docker networks

D Docker Compose

Multi-stage builds separate build and runtime environments, reducing image size.

What web server is commonly used inside Docker containers to serve Vue apps?

A IIS

B Apache

C Nginx

D Tomcat

Nginx is lightweight and efficient for serving static files like built Vue apps.

Which command runs a Docker container from your Vue app image?

A docker run -p 8080:80 your-image-name

B docker build your-image-name

C vue serve your-app

D npm start

The docker run command starts the container and maps ports for access.

Why is it important to build your Vue app before serving it in Docker?

A To create optimized static files for production

B To install Vue CLI inside the container

C To run the app in development mode

D To enable hot module replacement

Building creates optimized files that load faster and work well in production.
