We recently encountered this task failure with the error:

Error saving credentials: open /home/ubuntu/.docker/config.json103347037: permission denied

Docker daemon must run as the root user (https://docs.docker.com/engine/install/linux-postinstall/#:~:text=The%20Docker%20daemon%20always%20runs%20as%20the%20root%20user).

We need to update the antithesis_image_build.sh file to use sudo for all docker commands.
