Tagging & publishing

All variants share one repository (IMAGE); the variant is the tag. Each build gets a moving -latest tag, plus an immutable -VERSION tag when VERSION is set.

make push                       # ttyse/sbx-templates:{base,kube,ansible}-latest
VERSION=2026-06-26 make push    # ...also :<variant>-2026-06-26
IMAGE=ghcr.io/you/sbx make push # publish to a different repo

Versions

Tool versions are pinned as variables in docker-bake.hcl (GO_VERSION, KUBECTL_VERSION, TREE_SITTER_VERSION, …); override on the CLI, e.g. KUBECTL_VERSION=1.31.0 make kube.
