Dockerizing a Vue.js Application: Step-by-Step Tutorial

Dockerizing a Vue.js application allows you to package your application and its dependencies into a container, making it easier to deploy and run consistently across different environments. In this step-by-step tutorial, we will walk through the process of dockerizing a Vue.js application.

Step 1: Install Docker
Before we begin, make sure you have Docker installed on your machine. You can download and install Docker from the official website (

Step 2: Create a Vue.js Application
If you don’t already have a Vue.js application, you can create a new one using the Vue CLI. Open your terminal and run the following command:

vue create my-vue-app

This will create a new Vue.js application in a directory called "my-vue-app".

Step 3: Build the Vue.js Application
Navigate to the root directory of your Vue.js application:

cd my-vue-app

Next, build the application using the following command:

npm run build

This will generate a "dist" directory containing the built files of your Vue.js application.

Step 4: Create a Dockerfile
In the root directory of your Vue.js application, create a new file called "Dockerfile" (without any file extension). Open the file in a text editor and add the following content:

# Use an official Node.js runtime as the base image
FROM node:14-alpine

# Set the working directory in the container

# Copy package.json and package-lock.json to the working directory
COPY package*.json ./

# Install dependencies
RUN npm install

# Copy the built files to the working directory
COPY dist/ .

# Expose the container’s port

# Define the command to run the application
CMD [ "npm", "run", "serve" ]

This Dockerfile specifies a base image, sets the working directory, copies the package.json and package-lock.json files, installs dependencies, copies the built files, exposes the container’s port, and defines the command to run the application.

Step 5: Build the Docker Image
In your terminal, navigate to the root directory of your Vue.js application (where the Dockerfile is located). Run the following command to build the Docker image:

docker build -t my-vue-app .

This command builds a Docker image with the tag "my-vue-app" using the current directory as the build context.

Step 6: Run the Docker Container
Once the Docker image is built, you can run a Docker container based on that image. Run the following command:

docker run -p 8080:8080 my-vue-app

This command runs a Docker container based on the "my-vue-app" image and maps port 8080 of the container to port 8080 of the host machine.

Step 7: Access the Vue.js Application
Open your web browser and navigate to http://localhost:8080. You should see your Vue.js application running inside the Docker container.

Congratulations! You have successfully dockerized your Vue.js application. You can now distribute and deploy the Docker image to different environments with confidence that your application will run consistently.
