How do you version and distribute Docker dev environments consistently?
Tests immutable dev environment distribution. Strong answers cover: versioned Dockerfiles in Git, immutable image tags pushed to a registry, and enforcing identical pulls for CI and developers. Red flag: using the "latest" tag or local Dockerfile rebuilds.
Tests whether you can guarantee bitwise reproducible envs across dev laptops and CI. A strong answer covers four layers: first, commit Dockerfiles and Compose to Git; second, build images with immutable semantic tags or SHA digests and push to a private registry; third, pin exact digests in Compose or devcontainer configs so devs and CI pull identical layers; fourth, automate rebuilds when base images update. Red flag: relying on "latest", bind-mounting host tools, or local builds without a registry.
