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 <https://www.docker.com/pricing/retentionfaq>, 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 <https://www.docker.com/pricing/faq> as insurance.

It looks like if there are any images you want to ensure continue to survive published on DockerHub, you just need something/someone to pull a copy of them at least every 6 months (for example, via a periodic CI job or even cron running somewhere). Also making sure your contact address for the namespace on DH is correct and goes to someone who will notice the pending deletion notifications will help, as will checking the DH dashboard occasionally to see the status of those images. -- Jeremy Stanley
