EX188 Container Image Building Practice Question
When creating multi-architecture container images using podman build, how can you ensure that architecture-specific binaries are correctly handled when using instructions like COPY?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
By running podman build separately for each architecture and combining them with podman manifest.
Podman supports building for multiple architectures using buildah/podman features, where TARGETPLATFORM, TARGETOS, and TARGETARCH build args are automatically available.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
By setting the ARCH environment variable in the base image.
Why it's wrong here
Base images are specific to one architecture unless multi-arch manifests are used.
- ✗
By manually editing the Containerfile to include architecture-specific IF/ELSE statements.
Why it's wrong here
Containerfiles do not support native programmatic control-flow IF/ELSE blocks.
- ✓
By running podman build separately for each architecture and combining them with podman manifest.
Why this is correct
Using podman manifest is the standard way to combine single-arch images into a multi-arch list.
- ✓
By utilizing automatic build arguments such as TARGETOS and TARGETARCH provided in multi-arch build stages.
Why this is correct
Automatic build arguments like TARGETARCH allow conditional logic or selecting architecture-specific binaries during build.
