As this stands, isn't it possible for developers to accidentally SET the CreatedAt property?.  I think it is best if this was read only, to avoid bad code accidentally corrupting this field.

Hi Luiz,  yes - I ran into this too and implemented a similar approach, however - the last thing I do is then remove the license key from the image.

This is because I do not want (in my case at least), to build images which hold valid keys.  Especially if posting this the image to a public registry.

I would expect consumers of the image would bring their own license key.

Congrats ! Well Deserved !
