# Development Dockerfile with hot reload using Air
# TODO: Pin to SHA256 digest for reproducible builds:
# docker buildx imagetools inspect golang:1.26.5-alpine3.24
FROM golang:1.26.5-alpine3.24 AS development
# Image pinned to a SHA256 digest for reproducible builds; a registry
# tag mutation (Docker Hub allows re-tagging) cannot poison this build.
# To refresh: `docker buildx imagetools inspect golang:1.26.5-alpine3.24`
# (or use the Docker Hub API tags endpoint) and update the digest below.
# A Renovate / Dependabot config can automate this if desired.
# Keep this digest in sync with the builder stage in Dockerfile.
