node项目docker化

Dockerfile:

# A wildcard is used to ensure both package.json AND package-lock.json are copied
# where available (npm@5+)
COPY package*.json ./

RUN npm install
# If you are building your code for production
# RUN npm ci --only=production

# Bundle app source
COPY . .

生成镜像：

docker build -t m-app .

运行镜像文件：

docker run -it --rm --name my-running-app m-app

 

可以容器里通过命令访问测试一下：

curl -i localhost:81

通过命令暴露对外的端口即可正常访问：

docker run -p 81:81 -it --rm --name my-running-app m-app

 

在后台运行容器（-d）：

docker run -p 81:81 -d -it --rm --name my-running-app m-app

 postman测试接口：

创建镜像时加上用户名，可以把镜像上传的docker hub上：

docker build -t xutongbao/m-node-edu .

 

 

 

通过Docker Desktop启动容器，并暴露对外的端口号：
