海外TECH	DEV Community	An Ultimate Guide to Docker - From What is Docker to Dockerizing a Node.js Application	https://dev.to/suhailkakar/s-24cf	An Ultimate Guide to Docker From What is Docker to Dockerizing a Node js ApplicationDocker is an open source platform that allows us to create deploy and manage containerized applications In this article we will look at What is DockerBenefits of Using DockerPerformanceScalabilityRapid DeploymentCI EfficiencyDocker FactsInstallation of dockerMacLinuxDockerizing a node js appEnvironment SetupDockerfileDocker ImageDocker Containers What is DockerDocker is a container management service Docker s entire purpose is to make it simple for developers to create apps ship them into containers and then deploy them wherever they want Now let s discuss what are containers Containers are a solution to the challenge of moving software from one computing environment to another and having it operate consistently This might be from a developer s laptop to a test environment or from a real data center computer to a virtual machine in a private or public cloud A container is a whole runtime environment packaged into one package a program together with all of its dependencies libraries and other components and configuration files needed to run it Now that you have some knowledge about Docker and Containers let understand why should we use Docker Benefits of Using DockerBefore installing docker and dockerizing an application let s first understand what are the advantages of Docker Running applications in containers brings a number of benefits such as PerformanceDocker containers are usually fast and less resource intensive than virtual machines because containers do not contain an operating system whereas virtual machines do ScalabilityYou can quickly create new containers if demand for your applications requires them When using multiple containers you can take advantage of a range of container management options Rapid DeploymentDocker manages to reduce deployment to seconds This is because it generates a container for each process and does not boot an operating system CI EfficiencyDocker allows you to create a container image and utilize it throughout the whole deployment process The ability to isolate non dependent stages and perform them in parallel is a major advantage Now lets learn the facts about Docker that you might don t know Docker FactsDocker adoption is up in the last year PHP Ruby Java and Node are the main programming frameworks languages used in containers of organizations that try Docker end up utilizing it The majority of firms who will adapt did so within days of first production use and virtually all of the remaining adopters converted within days Docker offers a large library of pre built images At the time of writing there are over public Docker images available on the web Installation of docker MacIf you are using Mac with Apple silicon you must install Rosetta to do that simply run the below command in your terminal softwareupdate install rosettaVisit this link and select your mac chip Click on the blue button with your mac chip label on it Once you did a DMG file will be downloaded double click on it and you need to drag the docker logo into Applications folderOnce it is copied you will be able to access docker from the Applications folder LinuxTo install Docker in Linux you can simply run the below command in your terminal this would install everything related to docker in your Linux machine wget qO sh Dockerizing a node js appDockerizing is the process of packing deploying and running applications using Docker containers In this article we are going to dockerize a node js application but before starting it If you are using VS Code It is better to install Docker extension The Docker extension makes it easy to build manage and deploy containerized applications from Visual Studio Code It also provides one click debugging of Node js Python and NET Core inside a container Environment SetupIn this article I am going to create a simple node js application that send a get request but if you want you can also continue dockerizing your current application throughout this article To create a node js app from scratch you just need to runnpm initOnce you complete it a package json file will be generated Now you can create a new file named app js and this is going to be the file where we will be dockerizing it To send get the http request we need to set up express too so also need to install express js To do that simply runnpm i expressand once it is done you can create a simple GET request Here is the code for it const express require express const app express app get req res gt res send message Hey server is running D const port process env PORT app listen port gt console log Server is running on port port You can run this app by running node app js and your server will start on port You can open your browser and go to localhost in which your app is running and you will see similar output below image Now that we have our basic node js app setup let s start learning about Dockerfile DockerfileA Dockerfile is a text file that contains all of the commands that a user may use to construct an image from the command line Now go ahead and create a Dockerfile inside of your project directory The first thing we need to do is define from what image we want to build from Copy the below code and paste it into your dockerfile Don t worry I am going to explain each line FROM node WORKDIR appCOPY package json RUN npm installCOPY ENV PORT EXPOSE CMD node start In the above code FROM initializes a new build stage and sets the Base Image for subsequent instructionsWORKDIR is used to set the working directory for all the subsequent instructions COPY let you copy files from a specific location into a Docker image RUN allows you to install your application and packages required for it EXPOSE is a way to keep track of which ports are in use but it does not map or open any ports CMD ​specifies the instruction that is to be executed when a Docker container startsWe now have a full set of instructions to build a docker image Let s build it Docker ImageTo build a docker image we have to use below build commanddocker build OPTIONS PATH URL which in our case will bedocker build t lt your username gt nodedemo You should change to your docker hub username After the completion of this process a docker image will be created To see all your docker images run the following command in your terminaldocker images Docker ContainersNow that we have your docker images we can use them as a base image to createother images or we can use it to run containers Usually we use this image to push it to a container registry that might be docker hub or any cloud provider But in this article are going to push our image to docker hub To do that simply rundocker push lt your username gt nodedemoIf you got an access denied error then you need to login into your docker hub account to do that rundocker login and enter your email and password in your terminal Once you push your image to the docker hub you can access them in your docker hub profile ConclusionThat is it for this article I hope you found this article useful if you need any help please let me know in the comment section You can find the source code on my Github repository here Would you like to buy me a coffee You can do it here Let s connect on Twitter and LinkedIn Thanks for reading See you next time	2021-10-09 08:26:34
