So to sum up my question: is there a better way to manage NodeJS dependencies with Docker containers? Digging into Node.jss module resolving algorithm provides us with a way forward: Node.js will recursively look for node_modules in the current folder and all of its parent folders. How is Docker different from a virtual machine? Absolutely, the Dockerfile does work with no issues on that frot, however the node_modules folder would still be empty without a volume. Youll see some parameters that we didnt specify earlier in our Dockerfile. You see node_modules on your host machine, because of your volumes setup in your Compose file. To see a list of images we have on our local machine, we have two options. Instead of attempting to mount the containing folder and then exclude the node_modules directory, we explicitly state all the files and directories we actually want to mount, leaving out the node_modules folder. rev2023.3.17.43323. In the same way, when we use the FROM command, we tell Docker to include in our image all the functionality from the node:18-alpine image.

One of the first questions anyone asks when putting a Node.js app in Docker, is Which base image should I start my Node.js Dockerfile from?. Node.js applications are written in JavaScript and can be run within the Node.js runtime on Mac OS X, Windows, and Linux without changes. Your code will be mounted with the volume in Docker-compose but the dependencies will be there from your Dockerfile. You can then run your new image by entering docker run -it --rm --name my-running-app my-nodejs-app. That means if someone was to (accidentally) run an npm install within the running container at the /usr/local/app folder level, we would again pollute the exclude folder and introduce the third point of failure once again. Did I give the right advice to my father about his 401k being down? To take care of this I have put node_modules in its own volume but it still gets uploaded because, I think, the hash of the volume changes every time making it unique, even when there are no changes in packages. I wanted to come back and share a different opinion, since my POV has changed a bit since then, and I now think the way I wanted to use containers is incorrect. First, create a new directory where all the files would live. This means, we can go ahead and install the dependencies within the container one level above the actual app as once we run the app within the container it will also look for dependencies one level above. This image supports multiple CPU architectures like amd64, arm32v6, arm32v7, arm64v8, ppc641le, and s390x. Our image that was tagged with :v1.0.0 has been removed but we still have the node-docker:latest tag available on our machine. e.g. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. The core of this issue for Node.js is that node_modules can contain binaries compiled for your host OS, and if its different then the container OS, youll get errors trying to run your app when youre bind-mounting it from the host for development. Therefore, instead of creating our own base image, well use the official Node.js image that already has all the tools and packages that we need to run a Node.js application. This works with most Node.js code, but some larger frameworks and projects seem to hard-code in the assumption that node_modules is a subdirectory, which will rule out this solution for you. For Node.js I offer you two approaches, which come with their own benefits and limitations: Dont move node_modules. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, @vfsoraki that's not the case. This is probably a reasonable approach and surely works if youre the sole developer on the project, if youre collaborating on the project it may work if enforced as a convention but even if it can be enforced there are still reasons why you might want to support dual development, e.g. The Node.js community maintains this image alongside members of the Docker community.

The -t flag lets you tag your image so it's easier to This image supports multiple CPU architectures like amd64, arm32v6, arm32v7, arm64v8, ppc641le, and s390x. It could also be mitigated using dockers tmpfs volume driver which creates temporary volumes that only keep hold of their files while the container is running but sadly its only supported on Linux. Mount the local modules in each service's container at a separate path, e.g. So, after you build your image the image contains node_modules and you can use it to run your application. One alternative approach to ensuring that the node_modules path is different between the container image and the host system would be to use yarn, an alternative package manager that offers a --modules-dir option out of the box which allows you to specify a different path to install the node_modules in. build the Docker image. There is more to it than you see in the other answer though. another (anonymous or named) volume in the location where the node_modules reside within the container. This alone shrinks image size by 75%. I've found that this image is fine for creating a development image. Did Paul Halmos state The heart of mathematics consists of concrete examples and concrete problems"? I'm building a docker docker image for my Node.js application using the following Dockerfile: FROM keymetrics/pm2:latest RUN apk add --no-cache --update alpine-sdk python # Bundle APP files COPY package.json . For both of these solutions, always remember to add node_modules to your .dockerignore file (same syntax as .gitignore) so you'll never accidentally build your images with modules from the host. Debian or Ubuntu, couldnt find a source since docker does not provide these statistics but I guess you can find out doing some work research like this). instruction: Your app binds to port 8080 so you'll use the EXPOSE instruction to have it In recent years the slim image has shrunk down in size to 150MB and works the best across the widest set of scenarios. 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 In the age of containerization, developing Node apps within a docker container helps tremendously to simplify setup and ship the built app with all of its dependencies. Asking for help, clarification, or responding to other answers.
