海外TECH	DEV Community	Containerizing Node.js Applications with Docker	https://dev.to/c4r4x35/containerizing-nodejs-applications-with-docker-3020	Containerizing Node js Applications with Docker What is Docker Docker is a tool PaaS to make it easier to create deploy and run applications by using containers Docker uses OS level virtualization to deliver a software as a package called container Containers allow a developer to package up an application with all of the parts it needs such as libraries and other dependencies and ship it all out as one package Containers are designed to make it easier to provide a consistent experience as developers and system administrators move code from development environment into production in a fast and replicable way Docker is a powerful tool that allows you to package and deploy applications in lightweight containers In this article we will walk through the process of containerizing a Node js application using Docker Before we begin make sure you have Docker installed on your system You can check if Docker is installed by running the following command docker versionStep Create a Node js applicationFirst let s create a simple Node js application that we can containerize For this example we will create a simple Hello World server using the Express framework Create a new directory for your project and navigate to it mkdir node docker appcd node docker appNext create a file called server js in the project directory and add the following code const express require express const app express app get req res gt res send Hello World app listen gt console log Server is listening on port This code creates a simple Express server that listens on port and responds to HTTP GET requests with the message Hello World Next create a package json file in the project directory by running the following command npm init yThis will create a package json file with default values Next install the Express framework by running the following command npm install expressStep Create a DockerfileA Dockerfile is a text file that contains the instructions for building a Docker image We will use a Dockerfile to build an image for our Node js application Create a file called Dockerfile in the project directory and add the following code FROM node WORKDIR appCOPY package json RUN npm installCOPY EXPOSE CMD node server js This Dockerfile does the following It starts with a base image node which is a Docker image that includes Node js version It sets the working directory to app It copies the package json and package lock json files to the working directory It runs npm install to install the dependencies listed in the package json file It copies all the files in the current directory i e the project directory to the working directory It exposes port which is the port our application is listening on It sets the command to run when the container starts as node server js which will start the Node js server Step Build the Docker imageNow that we have a Dockerfile we can use it to build a Docker image for our Node js application To build the image run the following command in theproject directory docker build t node docker app This will build the Docker image and give it the name node docker app The at the end of the command specifies the current directory as the build context which is the directory that contains the Dockerfile and the files that will be copied into the image The build process may take a few minutes to complete Once it is finished you can check that the image was successfully created by running the following command docker imagesThis command will list all the Docker images on your system You should see the node docker app image in the list Step Run the Docker containerNow that we have a Docker image for our Node js application we can run it as a container To run the container use the following command docker run p node docker appThis command runs the node docker app image as a container and maps the container s port to the host s port You should see the message Server is listening on port in the output This means that the Node js server is running inside the container You can test the server by opening a web browser and navigating to http localhost You should see the message Hello World displayed in the browser ConclusionIn this tutorial we learned how to containerize a Node js application using Docker We created a simple Node js application created a Dockerfile to build an image for the application and ran the image as a container This is just a basic example of containerizing a Node js application with Docker There are many other options and configurations that you can use to customize the containerization process For more information you can refer to the Docker documentation	2022-12-18 10:09:00
