Structuring Compose files across environments
WHAT IT TESTS: Compose override and merge mechanics. OUTLINE: a base compose.yaml plus override files, the default override auto-merge, and explicit -f flags or extends per environment.
WHAT IT TESTS: whether you can layer Compose configuration cleanly rather than duplicate it. ANSWER OUTLINE: keep shared service definitions in a base compose.yaml, then a compose.override.yaml that Compose auto-merges for local dev, and named files like compose.ci.yaml selected via multiple -f flags. Explain that later files deep-merge and override scalars while lists for env can append. RED FLAG: maintaining separate full files per environment with copy-paste drift, or thinking -f replaces rather than merges configuration.
