But if you download both tripleopike/centos-binary-heat-api:current-tripleo and tripleopike/centos-binary-heat-engine:current-tripleo you will have only downloaded 266MB in total since the majority of those layers are shared. So it seems tripleo is building *all* images and then pushing them. Reworking your number leads me to believe you will be consuming 10-15GB in total on Dockerhub. Kolla images are only the size that you posted when built as seperate services. Just keep building all the images at the same time and you wont get anywhere near the numbers you posted. > When pulling the image, docker downloads 30 layers.
