docker 构建node最佳实践

注意：目前已经做了最佳实践 仓库docker-node
重点再此，经过多次实践，docker-node 我已经改良到只需简单几步就可以，具体直接看仓库的readme的例子即可

创建Dockerfile

ARG NODE_VERSION
FROM node:${NODE_VERSION}
WORKDIR /usr/src/app

RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.ustc.edu.cn/g' /etc/apk/repositories

RUN apk update && \
apk add --update git && \
apk add --update openssh

RUN apk add --no-cache python2 python2-dev make g++

构建node 镜像

  1. node版本

  2. 命令

       docker build . --build-arg NODE_VERSION=[node版本] -t [镜像名称]

  3. 例子

       docker build . --build-arg NODE_VERSION=14.18-alpine3.12 -t jenson/node-14.18

npm install

  1. 源

  2. 命令

     docker run -it --rm -v "$PWD":/usr/src/app \
   --name [名称] -w /usr/src/app \
   [镜像名] npm install --registry=https://registry.npm.taobao.org

  3. 例子

     docker run -it --rm -v "$PWD":/usr/src/app \
   --name vue-admin -w /usr/src/app jenson/node-14.18 \
   npm install --registry=https://registry.npm.taobao.org

npm start

  1. 命令

     docker run -it --rm -v  -w /usr/src/app  \
   --name [名称]  \
   [本地路径]:/usr/src/app
   -p [本地端口]:[容器端口] \
   [镜像] [npm 命令]

  2. 例子

       # vue run dev
   docker run -it --rm --name vue-admin \
     -v "$PWD":/usr/src/app \
     -w /usr/src/app \
     -p 9527:9527 \
     jenson/node-14.18  npm run dev
      
   # react start
   docker run -it --rm --name vue-admin \
     -v "$PWD":/usr/src/app \
     -w /usr/src/app \
     -p 9527:9527 \
     jenson/node-14.18  npm start

npm build

  1. 命令

     docker run -it --rm -v  -w /usr/src/app  \
   --name [名称]  \
   [本地路径]:/usr/src/app
   -p [本地端口]:[容器端口] \
   [镜像] [npm 命令]

  2. 例子

       docker run -it --rm --name vue-admin \
     -v "$PWD":/usr/src/app \
     -w /usr/src/app \
     -p 9527:9527 \
     jenson/node-14.18  npm run build

封装成脚本

    # set port
    PORT_SET=""

          exit 1
        fi
        PORT_SET="-p ${PORT}:${PORT}"
        echo "Port mapping is ${PORT_SET}"

    # Host generates global node_modules
    if [ ! -d "${NODE_NPM_GLOBAL_DIRECTORY}/bin" -o `ls ${NODE_NPM_GLOBAL_DIRECTORY}/bin/ | wc -l` -eq "0" ];then
      # Copy from within the container
      TEST_DOCKER_NODE_NAME="docker_test_node_name"
      docker rm ${TEST_DOCKER_NODE_NAME}
      docker run --name  ${TEST_DOCKER_NODE_NAME} ${IMAGE_NAME} /bin/sh -c "echo running test node"
      docker cp ${TEST_DOCKER_NODE_NAME}:/usr/local/lib/node_modules ${NODE_NPM_GLOBAL_DIRECTORY}/
      docker cp ${TEST_DOCKER_NODE_NAME}:/usr/local/bin ${NODE_NPM_GLOBAL_DIRECTORY}/
      docker rm ${TEST_DOCKER_NODE_NAME}
    fi

    # Stop containers that are already running again, if there are
    docker ps | grep "${CONTAINNER_NAME}" &&  docker stop "${CONTAINNER_NAME}" && sleep 2


    # Run docker
    docker run -it --rm --name $CONTAINNER_NAME \

node 一些问题

  • docker run -it --rm --name my-node-app -v "$PWD":/usr/src/app node:14-alpine3.12 /bin/sh

  • python not found

    • stackoverflow *

        # Install python/pip
  apk add --update --no-cache python2 && ln -sf python2 /usr/bin/python
  python2 -m ensurepip
  • alpine 源 sed -i ‘s/dl-cdn.alpinelinux.org/mirrors.tuna.tsinghua.edu.cn/g’ /etc/apk/repositories

国内可选源

  1. 腾讯源推荐： npm config set registry http://mirrors.cloud.tencent.com/npm/
