nuxt docker化

本文介绍了如何将nuxt.js项目docker化,包括创建Dockerfile,构建镜像,以及在过程中遇到的坑和解决方案。在构建镜像时需要注意配置文件的设置,以避免影响nuxt的正常运行。在实例化容器后,要正确配置端口映射以确保外部可以访问。此外,文章还提到了一个由于语法校验导致的启动失败问题,解决办法是删除特定的缓存目录。

nuxt docker 化

如何将nuxt docker化?

  1. 在项目根目录创建docker文件夹,并创建dockerfile文件

    # dockerfile
    FROM node:11.13.0-alpine AS builder
    MAINTAINER jiezai
    # create destination directory
    RUN mkdir -p /usr/src/nuxt-app
    WORKDIR /usr/src/nuxt-app
    # use taobao registry
    RUN npm config set registry https://registry.npm.taobao.org
    
    COPY nuxt-app/package.json nuxt-app/package-lock.json ./
    # build necessary, even if no static files are needed,
    # since it builds the server as well
    RUN npm install --no-optional
    
    FROM node:11.13.0-alpine
    MAINTAINER jiezai
    # create destination directory
    RUN mkdir -p /usr/src/nuxt-app
    WORKDIR /usr/src/nuxt-app
    # use taobao registry
    RUN npm config set registry https://registry.npm.taobao.org
    
    COPY nuxt-app/ /usr/src/nuxt-app/
    COPY --from=builder /usr/src/nuxt-app/node_modules ./node_modules
    
    #ENV NODE_ENV=production
    ENV HOST 0.0.0.0
    # set app serving to permissive / assigned
    #ENV NUXT_HOST=127.0.0.1
    # set app port
    ENV NUXT_PORT=5000
    
    # expose 5000 on container
    EXPOSE 5000
    
    RUN npm run build
    
    # start the app
    CMD [ "npm", "start" ]
    
    
  2. 构建镜像

    直接在docker 目录下执行docker build -t nuxt-demo .命令构建镜像,记住最后面有个.

  3. 通过mvn直接执行mvn clean install命令构建镜像(不需要的跳过)
    添加项目根目录下pom.ml文件,可以通过mvn clean install命令自动构建docker镜像(如不需要则跳过)

Dockerizing a Nuxt.js application involves creating a Docker image and running it in a Docker container. Here are the general steps to dockerize a Nuxt.js application: 1. Create a Dockerfile: Start by creating a Dockerfile in the root of your Nuxt.js project. This file will contain the instructions to build the Docker image. 2. Specify the base image: In the Dockerfile, specify the base image you want to use. For example, you can use the official Node.js image as the base image: ``` FROM node:14 ``` 3. Set the working directory: Set the working directory inside the Docker image where you want to copy your application files. For example: ``` WORKDIR /app ``` 4. Copy the application files: Copy the package.json and package-lock.json (or yarn.lock) files to the working directory, and then run the npm install or yarn command to install dependencies. For example: ``` COPY package*.json ./ RUN npm install ``` 5. Copy the rest of the application files: Copy the rest of your Nuxt.js application files to the working directory using the COPY instruction. For example: ``` COPY . . ``` 6. Build the application: Build your Nuxt.js application inside the Docker image using the npm run build or yarn build command. For example: ``` RUN npm run build ``` 7. Expose a port: If your application needs to listen on a specific port, use the EXPOSE instruction to expose that port. For example: ``` EXPOSE 3000 ``` 8. Define the startup command: Specify the command to start your Nuxt.js application inside the Docker container using the CMD instruction. For example: ``` CMD [ "npm", "start" ] ``` 9. Build the Docker image: Once you have the Dockerfile ready, you can build the Docker image using the docker build command. For example: ``` docker build -t my-nuxt-app . ``` 10. Run the Docker container: Finally, you can run the Docker container using the docker run command, mapping the exposed port to a port on your host machine. For example: ``` docker run -p 3000:3000 my-nuxt-app ``` These are the general steps to dockerize a Nuxt.js application. You may need to modify them based on your specific project requirements.
