Pinning Versions and Avoiding latest
Reproducible images and dependency versions.
Reproducibility Wins
A deploy you can repeat tomorrow and get the exact same result is reproducible. Pinning versions is how you guarantee that across installs and clusters.
The Trouble with latest
The latest image tag is a moving target. Two installs hours apart can pull different code, making bugs impossible to reproduce or roll back.
