@filipe.rinaldi - I updated my original post to note that the files in the generic folder will work with both x86_64 and armv8a architectures.
Regarding requirement 3: I’m guessing you’re talking about the ability to add additional repos into the Autoware workspace? If so, this can be added but it would be good to have a Gitlab issue to track this feature request. Would you mind adding one at Issues · Autoware Foundation / MovedToGitHub / docker · GitLab?
Regarding requirement 4: I recently updated the Gitlab wiki Docker pages, prior to the 1.12.0 release. Can you please review Docker · Wiki · Autoware Foundation / MovedToGitHub / autoware · GitLab and Generic x86 Docker · Wiki · Autoware Foundation / MovedToGitHub / autoware · GitLab and provide feedback? We do need armv8a-specific instructions but they will be very similar to the x86-specific instructions minus the Nvidia information.
