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
✓
Grant the 'system:image-puller' role to the ServiceAccount
Granting the 'system:image-puller' role to the ServiceAccount in the namespace where the image exists allows the builder to pull the image.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Change the build strategy to Docker
Why it's wrong here
Changing the strategy does not fix the underlying registry permission issue.
- ✗
Make the ImageStream public
Why it's wrong here
This is not a configurable setting and is insecure.
- ✓
Grant the 'system:image-puller' role to the ServiceAccount
Why this is correct
This grants the necessary permissions to pull images from other namespaces.
- ✗
Create an ImagePullSecret for the ServiceAccount
Why it's wrong here
While possible, assigning roles via RBAC is the standard OpenShift way for internal registry images.
