What's driving this significant download rate? This memory size can lead to different problems. : Distroless is a Docker image that is published by Google, it basically allows you to eliminate the OS in the containers to the bare minimum application that needs to run. Step 1: Creating Node.js Application. This variant is useful when final image size being as small as possible is your primary concern. The application is a typical web application that has frontend part (React.js) and backend part (Node.js server on . Docker Configuration and Setup. Another Reddit user mentioned their Node app ran 15% slower when using Alpine as a base image compared to Debian. I am fairly new to Docker and just managed to build my first few images with this Dockerfile: FROM strapi/base WORKDIR /src/app COPY ./package.json ./ COPY ./yarn.lock ./ RUN yarn install COPY .

One way to solve this issue is using a smaller base image like node:lts-slim or the node:lts-alpine image. With dive, . This depends on the project, but could FROM a base docker image of your project that already did a npm install, so that the new npm install that runs on the current code only stores the differences between those runs in the new docker image layer. But there's something you should pay attention to when it comes to distroless. Create a Dockerfile in your Node.js app project. We used node:12 as our base image in the previous configuration. Docker images consist of several layers, one for each command written in your Dockerfile. That really caught my eye. Vous verrez le rsultat suivant : From here we have ~100 MB of Node modules and 600 MB of the only base image. $ sudo mkdir nodejsdocker.

Run the following command to build the container: docker run --name nodejs-image-demo -p 80 :8080 -d your_dockerhub_username / nodejs-image-demo. . I'll show you now, how combining both these features you can build and ship extremely small and optimized nodejs docker images. Elasticsearch is also available as Docker images. It is a method to reduce the image size, create a better organization of Docker commands, and improve the performance while keeping the Dockerfile easy to read and understand. Both of these sets of images are based on the NodeJS Alpine containers. Docker has partnered with Snyk to provide the vulnerability scanning service. The standard node image also has a node:8-slim variant which is still Debian-based (and so larger than the Alpine image) but much tidier. Pushing Large docker images and making code changes. 600MB less than your previous image! Here are two possibilities: # Instead of using the full 930MB via 'FROM node:12' # Use the alpine image FROM node:12-alpine # OR # Use the slim image FROM node:12-slim Pretty easy, right?

As part of a number of optomisations to reduce the size it uses the musl libc instead of the . He also mentioned his Python apps were slower too. Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general. Each line in the Dockerfile is a separate instruction run from top to bottom (the order is important for proper optimization). We specify the 12.13 version of Node and choose an Alpine image.
