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.
Prerequisites
Before proceeding, ensure that you have the following prerequisites installed:
- Docker: Install Docker
- Vue CLI: Install Vue CLI
Step 1: Create a Vue App
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-app in a directory with the same name. Enter the directory by running:cd dockerized-vue-app
Step 2: Create a Dockerfile
To Dockerize our Vue app, we need to create a
Dockerfile in the root directory of our project. This file will contain instructions for building the Docker image.Create a new file named
Dockerfile and 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;"]
This
Dockerfile defines a multi-stage build. In the first stage, it uses the node:14 base image, copies the necessary files, installs dependencies, and builds the Vue app. In the second stage, it uses the nginx:1.21 base image and copies the built app from the previous stage. Finally, it exposes port 80 and starts the Nginx server.Step 3: Build the Docker Image
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.Step 4: Run the Docker Container
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-app image and maps port 8080 of the host machine to port 80 of the container.Now, if you visit
http://localhost:8080 in your browser, you should see your Vue app running inside the Docker container!Conclusion
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.
