Docker and CI/CD · Junior · Question 61 of 75

Why pin `FROM node:22.11-slim` instead of `FROM node`?

✓Correct answer: So builds don't silently change when the base updates
2So that Docker can skip downloading the base image
3Because untagged images can't be pulled from Docker Hub

Explanation

node means node:latest, which jumps major versions over time. A pinned tag (or even a digest) keeps builds reproducible; update it deliberately.
