The shortcomings of building based on the default node image are as follows Docker image builds are inconsistent. Just like we’re using lockfiles to get a deterministic npm ci behavior every time we install npm packages, we’d also like to get deterministic docker image builds. If we build the image from node—which effectively means the node:latest tag—then every build will pull a newly built Docker image of node. We don’t want to introduce this sort of non-deterministic behavior. The node Docker image is based on a full-fledged operating system, full of libraries and tools that you may or may not need to run your Node.js web application. This has two downsides. Firstly a bigger image means a bigger download size which, besides increasing the storage requirement, means more time to download and re-build the image. Secondly, it means you’re potentially introducing security vulnerabilities, that may exist in all of these libraries and tools, into the image. In fact, the node Docker image is quite big and includes hundreds of security vulnerabilities of different types and severities. If you’re using it, then by default your starting point is going to be a baseline of 642 security vulnerabilities, and hundreds of megabytes of image data that is downloaded on every pull and build. The recommendations for building better Docker images are Use small Docker images—this will translate to a smaller software footprint on the Docker image reducing the potential vulnerability vectors, and a smaller size, which will speed up the image build process Use the Docker image digest, which is the static SHA256 hash of the image. This ensures that you are getting deterministic Docker image builds from the base image. Based on this, let’s ensure that we use the Long Term Support (LTS) version of Node.js, and the minimal alpine image type to have the smallest size and software footprint on the image Attribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
