Select and build one cell

Use -s/--select for axis slices and --cell for exact slugs.

Select by axis values

tailor build gizmo -s variant=full,arch=amd64 --dry-run

Unset axes still expand. For example, if channel has two values, the command above selects two cells.

--select is repeatable:

tailor build gizmo \
  --select variant=full \
  --select arch=amd64 \
  --dry-run

Select by exact slug

List slugs:

tailor matrix gizmo --format slugs

Build one slug:

tailor build --cell gizmo_full_amd64_edge_cosi

Or pass the slug directly as a positional — tailor build <slug> is shorthand for tailor build <image> --cell <slug>:

tailor build gizmo_full_amd64_edge_cosi

Restrict architecture

--arch is a build-only convenience:

tailor build gizmo --arch amd64 --dry-run

Related commands that also accept selectors include validate, render, matrix, slugs, explain, and clean.
