talosctl-image/Dockerfile

# syntax=docker/dockerfile:1.7

# Build an OCI image that provides:
#  - talosctl
#  - talhelper
#  - sops
#
# Versions are controlled by build ARGs below. Renovate is configured to bump
# these ARGs automatically. The CI workflow builds the image and tags it with a
# composite version tag reflecting all three component versions.
