A folk-festival box-office service pins every environment to :latest, then a rollback cannot find the last good bits because the tag moved. Which image-management practice restores a reliable artifact pointer?
Select an answer to reveal the explanation.
Short Explanation
:latest is a sticky note that keeps getting peeled and moved. Versioned tags or digests are permanent library call numbers—you can always pull the edition that worked last Saturday.
Full Explanation
The :latest tag is a mutable pointer that advances with each push that uses it, so prior environments lose a stable reference for rollback. Semantic versions, build numbers, or content digests identify a specific immutable artifact. Registry deletion or untagged-only workflows remove the pin rather than fixing it.
