Dockerhub will be implemented a 6 month image retention limit on it's free accounts starting November first.  StarlingX have been using the free service up till now, so this applies to us.

Reading their Container Image Retention Policy FAQ, it looks like it's 6 months of inactivity, rather than 6 month since creation.  I don't think the risk is terribly high, but we may want to look into a payed plan as insurance.
