docker image maven and node

To help fix this such situations, Docker 17.05 introduced the ability to create multi-stage builds. This way everybody could simply rely on our Docker configuration to build the server. What I'm going to cover here is how to setup your Jenkins server in a Docker container and how to fix some of the limits of the Jenkins official image. It ensures your unit tests are executed everytime and can refresh your server with the compiled code if it builds successfully. If you are using npm version 5 or later, this will generate a package-lock.json file which will be copied to your Docker image. We could run our Jest unit tests, check the formatting of our project with Prettier and much more but I want to keep things simple for this example. We will create a working directory named backend and copy the content of the backend folder of our Git repository inside. Lastly, I add yarn, gulp, grunt, bower, and sass to our build. We are a Toronto-based end-to-end digital innovation firm with a passion for building beautiful & functional products that deliver results. Now you can leverage Docker to both build and deploy you web server quite easily. Usually, a container consists of an application running in a stripped-to-basics version of a Linux operating system. When you are a small team you have to do more with less. Finally, you will see the creation of the final Docker image. You will be able to find the IMAGE_ID on the last line of the logs of the build (here 9f26a180b872). For instance,Maven, the popular dependency management tool for Java, is not included in the Docker container. We could instead use Docker to not only deploy our application but also to build it. First of all, we would never find the perfect Docker image with every single development tool necessary to build our specific frontend and backend so we will have to do things ourselves. The goal of this example is to show you how to get a Node.js application into a Docker container. As major Open Source player, Obeo is a strategic member of the Eclipse foundation (alongside IBM, Oracle, SAP, Google) and a member of The Open Group. Lets consider a Spring-based backend with a React frontend, we would need to install Node.js and npm in our container to build our frontend while we wouldnt use any of them at runtime. An image is the blueprint for a container, a container is a running instance of an image. A naive approach would require us to install everything necessary in a Docker container, build the code and then run it inside of the container. Let's get you up and building faster. Problems start to occur when we need to update something in our build stack then everybody needs to update. Our backend will be a regular Spring Boot application with its entry point BackendApplication and its static resources which should be located in the folder src/main/resources/static. You can read more about this here. Then, create a server.js file that defines a web app using the Express.js framework: In the next steps, we'll look at how you can run this app inside a Docker container using the official Docker image. You've learned to create a Jenkins Docker-container that's ready to run jobs for Java, Ruby and NodeJS projects. If you want to see the real code, you can find it on my Github repository. In the case of a simple web application, the server can contain both the backend and the static resources of the frontend such as JavaScript files, images, CSS files, etc. I thought I'd share with you how we are increasing our productivity here at Quantum Mob. This allows us to take advantage of cached Docker layers. Now lets have a look at whats necessary in order to build our backend. Its entry point is the file index.js and we will build it using npm and its package.json located in the frontend folder. That can represent a very large amount of useless code at runtime. Validate an idea and launch a new product. Because we work with Java, JavaScript, and NodeJS at Quantum Mob, here is my modified file: Now we're going to add NodeJS to our container, based onnode.docker. If you have any question, dont hesitate to contact me on Twitter for more information. While it would work, it creates a couple of issues. In the first part of this guide we will create a simple web application in Node.js, then we will build a Docker image for that application, and lastly we will instantiate a container from that image. For that, we can use the official Node.js image which will contain both Node.js and npm. Our frontend build will stay mostly the same contrary to our backend build. This image will setup some details in order to run our web application, such as exposing the port 8080 and indicating how to run our server when a container based on this image will start. After that, we will build the backend with Apache Maven and finally copy just the executable server into a final Docker image without any development tools. In a cloud environment, you would end up paying for that one way or another. You build it and it runs the same everytime, everywhere. Trademarks and logos not indicated on the list of OpenJS Foundation trademarks are trademarks or registered trademarks of their respective holders. For a list of trademarks of the OpenJS Foundation, please see our Trademark Policy and Trademark List. But every members of our development team need to do the same and we also need to do it on our continuous integration servers. If you want to work with Ruby or NodeJS you'll notice those are missing as well. You can find more information about Docker and Node.js on Docker in the following places: Copyright OpenJS Foundation and Node.js contributors. You can wrap just about anything in a container, describing the container via a. Jenkinsis a continuous integration server. Here we will use node server.js to start your server: Your Dockerfile should now look like this: Create a .dockerignore file in the same directory as your Dockerfile with following content: This will prevent your local modules and debug logs from being copied onto your Docker image and possibly overwriting modules installed within your image. Thanks to this feature, you can use multiple Docker images during a build sequence, copy exactly what you need from one image to the next one and keep only what you need. 312 Adelaide St. W, Suite 800Toronto, ON M5V 1R2, Technology Trends CTOs Cant Ignore in 2021, 5 Ways Design Sprints Are Jet Fuel for Your Project. #sirius #capella #obeosmartea#web #eclipse #case-study#weareobeo. Then we will copy the result of the build from the image frontend into this static folder. Don't worry, before I get into the thick of it I'll provide a little background about Docker & Jenkins for those that haven't had much chance to play with them. Multi-stage Docker build for React and Spring. The OpenJS Foundation | To build our React project, we could simply write the following Dockerfile. Open the Dockerfile in your favorite text editor. Jenkins can speed up repetitive tasks that robots are much better performing and Docker simplifies spinning up VM's for your application in a very simple and repeatable way. Please note that if you are using npm version 4 or earlier a package-lock.json file will not be generated. When you are a small team you have to do more with less. Two of the greatest weapons we use to slice overhead to confetti are Jenkins and Docker. The Docker container used to run our server would contain some of our development tools used to compile and test our code. First, create a new directory where all the files would live. The OpenJS Foundation has registered trademarks and uses trademarks. Finally, we will trigger the regular Maven build. This will allow the most common NodeJS libraries to be present when we are building our projects. It makes your container bigger, so deploying it will be slower, it will consume more bandwidth to download etc. Once built, you can run the container using docker run -p 8080:8080 IMAGE_ID. Setting up NodeJS was certainly more verbose, but it handles downloading the tar as well as ensuring all the correct configurations have been made. The -p flag redirects a public port to a private port inside the container. We can quite easily install everything on our computer to build both our backend and our frontend, since we tend to do it all the time. First, we will use a folder named frontend as our working directory. Trademark List | This guarantees that the software will always run the same, regardless of its environment. Containerizationhelps by describing everything need to get an app running. We can now create our final image based on OpenJDK which will copy the final jar from the backend image. We will rely on the official Maven image in order to build our Spring application. It is very flexible and can perform quite a few tricks right out of the box. Lets use a simple Docker image in order to build our frontend. Now you can call your app using curl (install if needed via: sudo apt-get install curl): We hope this tutorial helped you get up and running a simple Node.js application on Docker. As a result, the jar produced to run our server will contain our React application. We will copy the content of the frontend folder from our Git repository inside and then we will install all our dependencies with npm ci and finally we will run our build. In this directory create a package.json file that describes your app and its dependencies: With your new package.json file, run npm install. Next time I'll cover how we automated all projects to use this version of Jenkins, which allows us to set up new projects across environments and hop on development in minutes. We could use an even smaller image to run our web application. No more head scratching wondering why itruns perfectly on your machinebut not in DEV. But in order to create our container we need to build our backend and frontend first. Use of them does not imply any affiliation with or endorsement by them. inside. In this post, we will have a look at an example in which, we will build our frontend using Node.js and npm then copy the result into our Java-based backend. Then we can run Maven in order to build our regular Spring application. You can have a look at the structure of the application below. Furthermore, the npm ci command, specified in the comments, helps provide faster, reliable, reproducible builds for production environments. bitJudo has a good explanation of this here. It offers webhooks that github, bitbucket, and others can call when you push your code which saves a lot of time. All rights reserved. The -t flag lets you tag your image so it's easier to find later using the docker images command: Running your image with -d runs the container in detached mode, leaving the container running in the background. Privacy Policy | Then we will run the build of the backend and finally we will copy the resulting jar in a final image which will only be used to run our web server. Our frontend is a regular React application create using Create React App. Trademark Policy | Let's make our Jenkins build a little more robust. OS binaries, all the software dependencies you need to install, environment variables absolutely everything. Think a lighter virtual machine on steroids with your application pre-installed. The first thing we need to do is define from what image we want to build from. Two of the greatest weapons we use to slice overhead to confetti are Jenkins and Docker. Here we will use the latest LTS (long term support) version 10 of node available from the Docker Hub: Next we create a directory to hold the application code inside the image, this will be the working directory for your application: This image comes with Node.js and NPM already installed so the next thing we need to do is to install your app dependencies using the npm binary. ), IT applications, digital transformation of large companies. In the backend build, we will create a folder named static for the static resources of the frontend in src/main/resources. First, you'll need to build a Docker image of your app. Then open your web browser on http://localhost:8080 and see your web application up and running. In our case, we will still use a simple Docker image with the official OpenJDK Docker image. The guide also assumes you have a working Docker installation and a basic understanding of how a Node.js application is structured. No more hours of debugging only to discover the version of node or java are different locally. Bylaws | Docker makes it easy to deploy web applications. Cookie Policy. Obeo provides open software solutions to create and transform complex systems: industrial systems (avionics, space, defense, energy, transportation, etc. To bundle your app's source code inside the Docker image, use the COPY instruction: Your app binds to port 8080 so you'll use the EXPOSE instruction to have it mapped by the docker daemon: Last but not least, define the command to run your app using CMD which defines your runtime. Fix performance and improve user experiences. In order to make our multi-stage build work, the image used to build the frontend will be named frontend and the one used to build the backend will be named backend. That would be an issue. Docker allows you to package an application with its environment and all of its dependencies into a "box", called a container. Run the image you previously built: If you need to go inside the container you can use the exec command: To test your app, get the port of your app that Docker mapped: In the example above, Docker mapped the 8080 port inside of the container to the port 49160 on your machine. While it is nice of Jenkins to offer an official docker image, you'll quickly run into a few issues if you are doing anything even slightly other than compiling plain Java. Note that, rather than copying the entire working directory, we are only copying the package.json file. Docker is the most popular containerization platform. Code of Conduct | Docker containers wrap a piece of software in a complete filesystem that contains everything needed to run: code, runtime, system tools, system libraries anything that can be installed on a server. We can build it thanks to its pom.xml located in the backend folder using Apache Maven. To run this example, clone my Github repository and run docker build . Terms of Use | You will see in the logs all the details of the build of the frontend and the backend. The guide is intended for development, and not for a production deployment. Go to the directory that has your Dockerfile and run the following command to build the Docker image. Receive summaries directly in your inbox. Now with a multi-stage Docker build, we want to use the result of the build of the frontend and integrate it inside the source code of our backend as static resources. Now we're all set with NodeJS and NPM.
