Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Using '--tls-verify=false' to bypass TLS verification when pulling base images from insecure registries.
Why this is correct
--tls-verify disables TLS checks for registry interaction.
- ✓
Using '--format oci' to explicitly specify that the resulting image should be in OCI image format rather than Docker v2.2.
Why this is correct
--format specifies OCI image format.
- ✓
Using '--no-cache' to force Podman to rebuild all layers from scratch without utilizing the cache.
Why this is correct
--no-cache bypasses existing cache.
- ✗
Using '--rm=false' to automatically keep intermediate build container containers indefinitely on disk after successful builds.
Why it's wrong here
--rm defaults to true, but keeping intermediate containers is controlled differently; --rm=false keeps failed containers, not successful ones indefinitely.
- ✗
Using '--privileged-build' to grant full root host capabilities to a rootless container build.
Why it's wrong here
Rootless builds cannot gain full root host privileges due to user namespace security boundaries.
