海外TECH DEV Community Mastering Docker: Writing Optimal Dockerfiles and Optimizing Image Size for Smarter Deployments https://dev.to/rokibulhasan114/mastering-docker-writing-optimal-dockerfiles-and-optimizing-image-size-for-smarter-deployments-13h2 Mastering Docker Writing Optimal Dockerfiles and Optimizing Image Size for Smarter DeploymentsIn the world of software development the concept of containerization has been gaining momentum over the last few years Among containerization tools Docker is one of the most popular ones Docker is an open source platform that allows you to create deploy and run applications in containers In this blog we will explore what Docker is why it is useful and how to write a Dockerfile What is Docker Docker is a containerization platform that allows you to run applications in containers A container is a lightweight and standalone executable package of software that includes everything required to run the application It includes the application code dependencies libraries and runtime environment Containers are isolated from the host system and other containers making them secure and portable Docker is built on top of Linux container technology which is known as LXC Docker provides a layer of abstraction over LXC and makes it easier to create deploy and manage containers Docker is designed to work with any language and any framework making it an ideal tool for developers and DevOps engineers Why use Docker Docker provides several benefits including Portability Docker containers can run on any platform that supports Docker making them highly portable Efficiency Docker containers are lightweight and use fewer system resources than traditional virtual machines Consistency Docker containers ensure that the application runs consistently across different environments such as development testing and production Isolation Docker containers provide a high degree of isolation between the application and the host system making them more secure How to write a DockerfileA Dockerfile is a script that contains instructions for building a Docker image An image is a read only template that is used to create a container The Dockerfile specifies the environment and dependencies required to run the application Here is an example of a Dockerfile for a Node js application Use the official Node js image as the base imageFROM node Set the working directory to appWORKDIR app Copy the package json and package lock json files to the working directoryCOPY package json Install the dependenciesRUN npm install Copy the rest of the application code to the working directoryCOPY Set the default command to run the applicationCMD npm start Let s break down the different instructions in this Dockerfile FROM This instruction specifies the base image that will be used to build the Docker image In this case we are using the official Node js image WORKDIR This instruction sets the working directory for the application The subsequent instructions will be executed in this directory COPY This instruction copies files from the host system to the Docker image In this case we are copying the package json and package lock json files to the working directory RUN This instruction executes a command inside the Docker image In this case we are running the npm install command to install the dependencies required by the application CMD This instruction specifies the default command that will be run when a container is created from the Docker image In this case we are running the npm start command to start the application To build the Docker image save the Dockerfile to a directory and navigate to that directory in a terminal Then run the following command docker build t my node app This command builds a Docker image with the tag my node app using the Dockerfile in the current directory To run the Docker container use the following command docker run p my node appThis command starts a container from the my node app image and maps port in the container to port on the host system The application should now be accessible at http localhost How to Reduce the Size of Docker ImagesOne of the benefits of using Docker is the ability to package an application with all of its dependencies into a single container However the size of Docker images can become an issue especially when deploying to cloud platforms with limited storage and bandwidth Here are some techniques to reduce the size of Docker images Use Alpine LinuxAlpine Linux is a lightweight and secure distribution of Linux that is designed for containerization Alpine Linux uses a minimal set of packages and libraries which results in smaller Docker images Many official Docker images such as the Node js image offer Alpine variants For example to use the Alpine version of the Node js image in the Dockerfile use the following command FROM node alpine Minimize the number of layersA Docker image is built from a series of layers and each layer represents a change to the filesystem The more layers a Docker image has the larger it becomes To reduce the size of Docker images it is recommended to minimize the number of layers You can do this by combining multiple commands into a single RUN instruction like so RUN apt get update amp amp apt get install y package package package amp amp apt get clean amp amp rm rf var lib apt lists This example installs three packages and removes the package cache in a single layer Remove unnecessary filesRemoving unnecessary files can significantly reduce the size of Docker images For example removing the npm debug log file generated during the npm install command can save a few megabytes You can use the dockerignore file to exclude files and directories from the build context like so node modulesnpm debug logThis example excludes the node modules directory and the npm debug log file from the build context Use multi stage buildsMulti stage builds allow you to use multiple FROM instructions in a single Dockerfile With multi stage builds you can create a temporary build image with all the necessary build tools and dependencies and then copy the built artifacts to a smaller final image This technique can significantly reduce the size of Docker images Here is an example of a multi stage build for a Node js application Build stageFROM node alpine as buildWORKDIR appCOPY package json RUN npm installCOPY RUN npm run build Final stageFROM node alpineWORKDIR appCOPY from build app dist appCMD npm start This example creates a temporary build image with Node js and Alpine Linux installs the dependencies builds the application and copies the built artifacts to a smaller final image with Node js and Alpine Linux Use a smaller base imageIf you re building a custom Docker image you can consider using a smaller base image than the official images provided by Docker Some examples of smaller base images include BusyBox Scratch or Distroless By using these techniques you can significantly reduce the size of Docker images and improve the efficiency of your Docker based application deployments ConclusionDocker is a powerful containerization platform that provides many benefits to developers and DevOps engineers Writing a Dockerfile is an essential part of building a Docker image and it allows you to specify the environment and dependencies required to run your application By following the instructions in this blog you should now have a basic understanding of how to write a Dockerfile and build a Docker image for your Node js application 2023-03-06 05:04:23
