# images and the 2nd value being the architecture to build snaps for.
# Values should be something like `v0.34.0` or `nightly`. The given value is
# only the base of the tag because the things like the CPU architecture are
# also added to the full tag.

# Creates and pushes all Docker images aliases for the requested architectures
# set in the environment variable ALL_REQUESTED_ARCH. If the value of the
# global variable TAG_BASE is a version tag such as v0.35.0, the "latest" tag
# is also updated. Tags without the architecture part are also created for the
# default architecture.
# As an example, for amd64 (the default architecture) and the tag v0.35.0, the
# following tags would be created:
# - certbot/certbot:v0.35.0
# - certbot/certbot:latest
# - certbot/certbot:amd64-latest
# For the architecture arm32v6 and the tag v0.35.0, only the following tag
# would be created:
# - certbot/certbot:arm32v6-latest
# For other tags such as "nightly", aliases are only created for the default
# architecture where the tag "nightly" would be used without an architecture
# part.
# Usage: TagAndPushForAllRequestedArch [IMAGE NAME]
# where [IMAGE NAME] is the name of the Docker image in the Docker repository
# such as "certbot" or "dns-cloudflare".

# * TAG_BASE
