We currently use this syntax when calling docker in frontend builds:
docker --config="$DOCKER_CONF" build -t "${IMAGE{color:#ce9178}}:$color}IMAGE_TAG{color:#ce9178" $APP_ROOT -f $APP_ROOT/Dockerfile
 
The --config is the part I'm highlighting. This doesn't work on all jenkins nodes. So, it was suggested to move to $OCKER_CONFIG and docker will use it automatically, as will podman.
