Which s2i command tests a local build using the image phpbuild:latest with source in the ./app and tags it as php:1?

• A. s2i test ./app phpbuild:latest php:1
• B. s2i build ./app phpbuild:latest php:1
• C. s2i build ./app phpbuild:latest php
• D. s2i build ./src phpbuild:latest php:1

Answer: (B)

The key idea is using the build flow of Source-to-Image to create a new image from local source. s2i build takes three things in order: the path to the local source, the builder image, and the name or tag for the output image. Here you want to build from the source in ./app, using the builder image phpbuild:latest, and tag the resulting image as php:1, so the command matches exactly: s2i build ./app phpbuild:latest php:1.

Using s2i test would not produce a new built image with a tag; it tests an existing image instead. That’s why the option with test isn’t appropriate for performing a local build and tagging the result.

Choosing a different output tag (like php without a version) or pointing to a different source path (like ./src) doesn’t align with the stated requirements, so those don’t fit the scenario.
