How to use docker containerization to deploy applications in Vue

Docker has become a very popular solution in the development and deployment of modern web applications. The basic idea of ​​Docker technology is to integrate applications, services and various other dependencies together through the use of container technology. This will make applications easier to deploy, test, and maintain in multiple environments. At the same time, for Vue.js application developers, Docker technology also provides a convenient containerized deployment solution, which can help quickly deploy and maintain applications.

This article will introduce how to containerize and deploy Vue.js applications into Docker and share some useful tips and best practices.

Basic concepts

Before we start introducing Docker containerization to deploy Vue.js applications, we need to understand some basic concepts.

1. Docker: An open source containerization technology that uses containers to package, deploy, and distribute applications.
2. Container: A lightweight and independent application running environment that can contain applications, services, runtime environments, dependencies, etc.
3. Image: A preconfigured container environment that includes the operating system, applications, services, libraries, and all dependencies.
4. Warehouse: Where Docker images are stored, including private warehouses and public warehouses.

Docker containerization to deploy Vue.js applications

Below, we will introduce in detail how to use Docker containerization to deploy Vue.js applications.

1. Create a Vue.js application

First, we need to create a Vue.js application. If you already have a Vue.js application, skip this step.

Vue.js is a lightweight and efficient JavaScript framework. Using Vue.js, you can easily build interactive and responsive user interfaces. You can create a new Vue.js application using the Vue CLI with the following command.

$ vue create my-app

2. Create a Dockerfile

Dockerfile is a text file that contains instructions on how to build an image in Docker. The following is a basic Dockerfile example for building a Vue.js application image.

# 基于官方的 Node.js 镜像
FROM node:14.17.0-alpine

# 设定工作目录
WORKDIR /app

# 复制package.json和package-lock.json
COPY package*.json ./

# 安装依赖
RUN npm install

# 将其他文件都拷贝到/app文件夹内
COPY . .

# 编译打包
RUN npm run build

# 启动Nginx
FROM nginx

# 复制/dist文件夹到Nginx的默认文件夹
COPY --from=0 /app/dist /usr/share/nginx/html

3. Build the Vue.js application image

Use the following command to build the Vue.js application image:

$ docker build -t my-app .

4. Run the Docker container

Use the following command to execute the Vue.js application container:

$ docker run -p 8080:80 my-app

Among them, -p 8080:80 means mapping port 80 in the container to port 8080 of the host.

Now you can view your Vue.js application by visiting http://localhost:8080 in your browser.

5. Deploy using Docker Compose

If your Vue.js application depends on other services or databases, you can use Docker Compose to define and run multiple containers at once.

The following is a simple docker-compose.yml file example that defines a Vue.js application and MySQL database container. Using the docker-compose up command will start the service.

version: '3.1'

services:
  db:
    image: mysql:5.7
    environment:
      MYSQL_ROOT_PASSWORD: example

  frontend:
    build: .
    ports:
      - "8080:80"

Best Practices

In addition to the above steps, here are some best practices that you should pay attention to when deploying Vue.js applications using Docker containerization.

1. Use the alpine version of the image: Alpine Linux is a lightweight Linux distribution that is very suitable for running in a container environment. Using the alpine version of the Node.js image can reduce the image size.
2. Manage container size: Avoid using too large images and manage shared volumes and caches within the container.
3. Ensure application isolation from containers: exclude Node modules files and other unnecessary files from the container, and use .env files or configuration files to separate confidential information.
4. Understand Docker security: Know Docker security issues and best practices, such as reducing the use of root users and avoiding excessive exposure of network ports.

Summary

Docker technology can make the deployment of Vue.js applications easier and more efficient. By combining applications, services, and dependencies in a single container, we can easily and quickly distribute applications and improve deployment and maintenance efficiency. Hopefully the tips and best practices provided in this article will help you better deploy your Vue.js applications using Docker containerization.
