Description

In autoware docker installation , when it comes to the section How to setup a workspace, the instructions are using rocker.

Actually this step pull the image (equivalent to docker pull), build something, then start the container.

During the image pull, there is no any progress update bar or any information to tell about that.

Knowing that the image size may exceed 8 GB ... so for a new user it is easily to be interpreted that the rocker command is not doing anything or there is something wrong.

So adding a step before using rocker to do docker pull ghcr.io/autowarefoundation/autoware-universe:latest-cuda then do the rocker step, is way more better as docker pull is actually telling you the pull progress

Purpose

• Fixing long wait without any progress update for new installation / new users using rocker command
• Fixing false impressions that rocker command is not doing anything or something going wrong

Possible approaches

Update the How to setup a workspace section to add docker pull ghcr.io/autowarefoundation/autoware-universe:latest-cuda before rocker step, similar to how to update a workspace

Definition of done

The How to setup a workspace section is updated as described in the task.
