# Setup - creates the local repo which will be mirrored up to S3, then back-fill it. Your
#         future deploys will eliminate all old versions without these backfill steps:
#   aptly repo create signal-desktop
#   aptly mirror create -ignore-signatures backfill-mirror https://updates.signal.org/desktop/apt xenial
#   aptly mirror update -ignore-signatures backfill-mirror
#   aptly repo import backfill-mirror signal-desktop signal-desktop signal-desktop-beta
#   aptly repo show -with-packages signal-desktop
#
# First run on a machine - uncomment the first set of 'aptly publish snapshot' commands,
#   comment the other two. Sets up the two publish channels, one local, one to S3.
#
# Testing - comment out the lines with s3:$ENDPOINT to publish only locally. To eliminate
#          effects of testing, remove package from repo, then move back to old snapshot:
#   aptly repo remove signal-desktop signal-desktop_1.0.35_amd64
#   aptly publish switch -gpg-key=57F6FB06 xenial signal-desktop_v1.0.34
#
# Pruning package set - we generally want 2-3 versions of each stream available,
#                       production and beta. You can remove old packages like this:
#   aptly repo show -with-packages signal-desktop
#   aptly repo remove signal-desktop signal-desktop_1.0.34_amd64
#
# Release:
#   NAME=signal-desktop(-beta) VERSION=X.X.X ./aptly.sh
