#!/usr/bin/env bash
# aptly-push — upload one or more .deb/.dsc/.changes files into an aptly local
# repo and (by default) refresh the publish that serves it. Works unchanged
# against every security.preset in the Helm chart's matrix: pass credentials
# via APTLY_USER/APTLY_PASSWORD, APTLY_TOKEN, or neither for an open repo.
#
# Usage:
#   aptly-push --repo stable [--prefix ""] [--distribution stable] \
#              [--no-publish] [--no-force-replace] [--no-sign] FILE.deb [FILE2.deb ...]
#
# Signing note: aptly-push runs as an external actor (CI, a developer's
# laptop) and generally has no access to the aptly-server pod's GNUPGHOME or
# /run/aptly/signing.json — only aptly-init and aptly-reconcile, which run
# inside that pod, do. So by default aptly-push sends NO Signing field at all
# on the publish-refresh call, letting the server use its own configured
# default signer (this is the correct behaviour for a signed repo). Pass
# --no-sign (or APTLY_GPG_SIGN=false) only when you know the target repo is
# genuinely unsigned (aptly.gpg.enabled: false) — otherwise the update call
# will fail with a clear "no GPG key" error rather than silently publishing
# unsigned.
#
# Env (all overridable by the matching flag):
#   APTLY_URL (required, from lib/common.sh)  APTLY_REPO  APTLY_PREFIX  APTLY_DISTRIBUTION  APTLY_GPG_SIGN
