Nuxt 入门实战 - 13：docker 打包部署

编写打包配置Dockerfile

说明：Dockerfile 放置在项目根目录下

tsx

# use node 16 alpine image
FROM node:16-alpine as builder

# create work directory in app folder
WORKDIR /app

# install required packages for node image
RUN apk --no-cache add openssh g++ make python3 git

# change time zone
ENV TZ=Asia/Shanghai \ DEBIAN_FRONTEND=noninteractive
RUN apk add --no-cache tzdata
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

# copy over package.json files
COPY package.json /app/
COPY pnpm-lock.yaml /app/

# install pnpm
RUN npm install -g pnpm

# install all depencies
RUN npx pnpm i && pnpm store prune
#RUN npx npm install

# copy over all files to the work directory
ADD . /app

# build the project
RUN npx pnpm build

# start final image
FROM node:16-alpine

WORKDIR /app

# copy over build files from builder step
COPY --from=builder /app  /app

# expose the host and port 3000 to the server
ENV HOST 0.0.0.0
EXPOSE 3000

# run the build project with node
ENTRYPOINT ["node", ".output/server/index.mjs"]

打包

bash

docker build -t project_name:[tag] .

# example
docker build -t nuxt_demo:0.0.1 .

由于打出来是一个镜像，我们需要推送至远程镜像仓库，方便在服务器通过pull拉取镜像文件，所以我们创建阿里云镜像仓库（为啥不用hub.docker，因为根本没法用，经常登录不上）

阿里云创建镜像仓库

创建仓库

推送镜像至仓库

bash

# 1. login mirror repository
docker login --username=username registry.cn-shenzhen.aliyuncs.com
# 2. create tag
docker tag [ImageId] registry.cn-shenzhen.aliyuncs.com/xxx/nuxt_demo:[镜像版本号]
# 3. docker push 
docker push registry.cn-shenzhen.aliyuncs.com/xxx/nuxt_demo:[镜像版本号]

# 说明：xxx 是镜像仓库的命名空间

启动服务

bash

# docker pull 
docker pull registry.cn-shenzhen.aliyuncs.com/xxx/nuxt_demo:latest

# docker start
docker run -itd -p 9001:3000 imageid

自动化脚本

build.sh

bash

#!/bin/bash

echo "welcome to local-ubuntu"

cd /home/potter/nuxt-demo

# 拉取最新代码
git pull

# 修改 .npmrc 文件，让其自动确认避免提示确认选择
echo "yes=true" >> ~/.npmrc

# install pnpm
npm install pnpm -g 

# install dependency
pnpm install --force

# 步骤 1: 打包镜像
docker build -t nuxt-demo .
if [ $? -eq 0 ]; then
	  echo "打包成功！"
  else
	    echo "打包失败，请检查输入的信息。"
	      exit 1
fi

# 提供Docker镜像仓库地址、用户名和密码
registry="registry.cn-shenzhen.aliyuncs.com"
username="xxx"
password="xxx"

# 使用expect来实现自动登录
expect -c "
spawn docker login $registry
expect \"Username: \"
send \"$username\n\"
expect \"Password: \"
send \"$password\n\"
expect \"Login Succeeded\"
"

# 检查登录是否成功
if [ $? -eq 0 ]; then
	  echo "登录成功！"
  else
	    echo "登录失败，请检查输入的信息。"
	      exit 1
fi

# 给镜像打标签
new_image_id=$(docker images -q nuxt-demo)
docker tag $new_image_id registry.cn-shenzhen.aliyuncs.com/e7show/nuxt-demo

# 检查标签是否成功
if [ $? -eq 0 ]; then
	  echo "Docker镜像标签成功！"
  else
	    echo "Docker镜像标签失败。"
	      exit 1
fi

# 推送镜像到远程仓库
docker push registry.cn-shenzhen.aliyuncs.com/e7show/nuxt-demo:latest

# 检查推送是否成功
if [ $? -eq 0 ]; then
	  echo "Docker镜像推送成功！"
  else
	    echo "Docker镜像推送失败。"
	      exit 1
fi

echo "全部操作完成。"

restart.sh

bash

echo "welcome 243"

# 步骤 1: pull 最新镜像
docker pull registry.cn-shenzhen.aliyuncs.com/e7show/nuxt-demo:latest

# 步骤 2: 查询并停止旧容器
container_name="nuxt-demo"
container_id=$(docker ps -aqf "name=$container_name")

if [ -n "$container_id" ]; then
    echo "Stopping the existing container: $container_name"
    docker stop $container_id
    docker rm $container_id
fi

# 步骤 3: 启动容器
image_id=$(docker images | grep $container_name | sort -k5,5 -r | head -n 1 | awk '{print $3}')
if [ -n "$image_id" ]; then
    echo "Starting a new container from image: $image_id"
    docker run --name $container_name -itd -p 9001:3000 $image_id
else
    echo "No image found. Build the image first."
fi

clean.sh

bash

#!/bin/bash

# 定义要清理的镜像名称
image_name="registry.cn-shenzhen.aliyuncs.com/e7show/nuxt-demo"

# 获取所有的镜像 ID，根据创建时间进行排序
image_ids=$(docker images | grep "$image_name" | sort -k5,5 -r | awk '{print $3}')

# 获取镜像数量
image_count=$(echo "$image_ids" | wc -l)

# 保留的镜像数
keep_count=1

# 开始清理镜像
if [ $image_count -gt $keep_count ]; then
  images_to_remove=$(echo "$image_ids" | tail -n +$((keep_count + 1)))
  echo "delete count: $images_to_remove"	

  echo "Cleaning up old $image_name images..."
	      
  for image_id in $images_to_remove; do
    #docker rmi -f $image_id
    echo "remove $image_id success"
  done

  echo "Cleanup complete."

else
      echo "No old $image_name images to clean up."
fi
