前端基于Dockerfile构建Docker镜像

【基于Dockerfile构建Docker镜像, 并推送到Docker仓库】

1. 安装Docker
2. 项目根目录下新增Dockerfile文件、nginx.conf文件 （查看下方文件详情）
3. 执行命令，构建Docker镜像 docker build -t your-image-name . 如： docker build -t myy-integration-ui .
4. 执行命令，运行容器 docker run -p 8080:80 your-image-name 如： docker run -p 8080:80 myy-integration-ui
5. 修改镜像tag， 如：docker tag myy-integration-ui:latest 190.160.x.xx:8083/myy-integration-ui:1.0.0
6. 将镜像推送到Docker仓库
   6.1 windows修改docker Insecure Registries, 设置非安全访问的仓库
   步骤 1：打开 Docker Desktop 设置
   步骤 2：转到 Daemon 设置 （在 Docker Desktop 设置窗口中，找到 “Docker Engine” 选项卡，并点击它。这将打开 Docker Daemon 的配置文件。）
   步骤 3：添加不受信任的镜像仓库（在打开的配置文件中，找到 “insecure-registries” 一节。如果没有该部分，你需要手动添加它。“insecure-registries”:[“190.160.x.xx:8083”, “190.160.x.xx:8084”]）
   步骤 4：保存并重启 Docker Desktop（点击 “Apply & Restart” 按钮）
   6.2 登录docker仓库：docker login 190.160.x.xx:8083 --username xxxxx
   回车输入密码 xxxxx
   6.3 推送镜像到私服：docker push 190.160.x.xx:8083/myy-integration-ui:1.0.0

【在项目根目录下创建Dockerfile】

# Stage 1: 构建Node.js应用 
FROM node:16.14.0 AS builder
WORKDIR /app 
RUN npm cache clean —force
COPY package*.json ./
RUN npm install --force
COPY . .
RUN npm run build:sit

# Stage 2: 构建Nginx镜像
FROM nginx:latest
WORKDIR /usr/share/nginx/html

# 将Node.js应用构建结果复制到Nginx镜像中
COPY --from=builder /app/dist/ .

# 可选：复制Nginx配置文件
COPY nginx.conf /etc/nginx/nginx.conf

# 暴露端口
EXPOSE 80

# 启动Nginx
CMD ["nginx", "-g", "daemon off;"]

【在项目根目录下创建nginx.conf】

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

    worker_connections  1024;

                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    gzip  on;

    gzip_buffers 4 16k;
    gzip_comp_level 9;

    gzip_types text/plain application/javascript application/css  text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png;

    server {

        listen  [::]:80;
        server_name  localhost;
        location / {
            root   /usr/share/nginx/html;
            index  index.html index.htm;
            try_files $uri $uri/ /index.html;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        }

    }
}
