In this article, we will explore how to Dockerize a Vue application.
Dockerizing your application allows for easy deployment, scalability, and reproducibility across different environments.
We will cover the necessary steps to containerize a Vue app using Docker.
Before proceeding, ensure that you have the following prerequisites installed:
- Docker: Install Docker
- Vue CLI: Install Vue CLI
First, let's create a new Vue application using the Vue CLI. Open your terminal and run the following command:
vue create dockerized-vue-app
This will create a new Vue app named
dockerized-vue-appin a directory with the same name. Enter the directory by running:
To Dockerize our Vue app, we need to create a
Dockerfilein the root directory of our project. This file will contain instructions for building the Docker image.
Create a new file named
Dockerfileand add the following content:
# Base image FROM node:14 as build # Set working directory WORKDIR /app # Copy package.json and package-lock.json COPY package*.json ./ # Install dependencies RUN npm install # Copy the rest of the app's code COPY . . # Build the app RUN npm run build # Production image FROM nginx:1.21 # Copy built app from previous stage COPY --from=build /app/dist /usr/share/nginx/html # Expose port 80 EXPOSE 80 # Start Nginx server CMD ["nginx", "-g", "daemon off;"]
Dockerfiledefines a multi-stage build. In the first stage, it uses the
node:14base image, copies the necessary files, installs dependencies, and builds the Vue app. In the second stage, it uses the
nginx:1.21base image and copies the built app from the previous stage. Finally, it exposes port 80 and starts the Nginx server.
To build the Docker image of our Vue app, run the following command in the terminal:
docker build -t dockerized-vue-app .
This command builds the Docker image with the tag
dockerized-vue-app. Make sure to include the
.at the end, as it specifies the build context as the current directory.
Once the Docker image is built, we can run a Docker container based on that image. Execute the following command:
docker run -p 8080:80 dockerized-vue-app
This command runs a Docker container based on the
dockerized-vue-appimage and maps port 8080 of the host machine to port 80 of the container.
Now, if you visit
http://localhost:8080in your browser, you should see your Vue app running inside the Docker container!
In this article, we learned how to Dockerize a Vue application. We went through the steps of creating a Vue app, writing a Dockerfile, building a Docker image, and running a Docker container. Dockerizing your Vue app enables easy deployment and scalability, making it a valuable skill for seasoned developers.
