Description

@youtalk -san, I think the latest keyword is also becoming redundant, what do you think of removing it?
Is there a benefit in keeping the latest keyword?

Before	After
autoware:latest-base	autoware:base
autoware:latest-core-devel	autoware:core-devel
autoware:latest-universe-devel	autoware:universe-devel
autoware:latest-devel	autoware:devel
autoware:latest-universe	autoware:universe

Purpose

To not have redundant keywords in images.

Possible approaches

Definition of done

• Docker image tags don't have latest keyword anymore.
• Dependent repos are updated.

According to the discussion https://github.com/orgs/autowarefoundation/discussions/4995 I approved.
However I would like to remain the autoware:latest tag to be the same as the autoware:universe tag for a while.

It's alright to have autoware:latest 👍

autoware:latest can be good and a needful simplification to users

This is not my emergent issue.
I'm waiting for your contribution not only by discussion but by PR.
Thanks.
