const HOST = '0.0.0.0';
// App
const app = express();
app.get('/', (req, res) => {
res.send('Hello World');
});
app.listen(PORT, HOST);
console.log(`Running on http://${HOST}:${PORT}`);
创建一个名称为 Dockerfile 的文件#
touch Dockerfile
FROM node:16
# Create app directory
WORKDIR /usr/src/app
# Install app dependencies
# 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 . .
EXPOSE 8080
CMD [ "node", "server.js" ]
.dockerignore 文件#
vi .dockerignore
node_modules
npm-debug.log
构建你的镜像#
docker build . -t t5750/node-web-app
运行镜像#
docker run -p 49160:8080 -d --rm --name node-web-app t5750/node-web-app
curl -i localhost:49160
