Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

DockerHub replacement stratagy and options
IPDR is a service to allow for images stored on IPFS to be accessible over Docker Registry HTTP API V2 Spec

Docker's deleting Open Source images and here's what you need to know
Probably. You still need to store and serve the data somewhere of course but for even moderately successful open source organizations they will likely find volunteer mirrors. The nice thing about IPFS is that new people can start mirroring content without any risk or involvement, new mirrors are auto-discovered, like bittorrent.
It seems like the docker registry format isn't completely static so I don't think you can just use a regular HTTP gateway to access but there is https://github.com/ipdr/ipdr which seems to be a docker registry built on IPFS.
> We'd still need a registry for mapping the image name to CID, along with users/teams/etc.
IPNS is fairly good for this. You can use a signing key to get a stable ID for your images or if you want a short memorable URL you can publish a DNS record and get /ipns/docker.you.example/.
Of course now you have pushed responsibility of access control to your DNS or by who has access to the signing key.

Using ECR as a mirror to transparently proxy docker-hub when rate limited
I’m trying out spegel, so far, it’s been great

Constantly re-pulling the same image(s)?
As other stated, check disk space, PullPolicy etc. However, local caching can be done using tools like Spegel that makes sure each node gets all images used in the cluster for faster restarts.

Pull through cache, like AWS just announced
I also recently found spegel, where each Cluster Node provides its images to the other nodes: https://github.com/XenitAB/spegel

https://github.com/xenitAB/spegel
I have avoided a couple of incidents caused by images being removed or momentarily not reachable with it. It would at least mitigate any immediate issues caused by images being removed from Docker Hub.
- I created Spegel to enable nodes in a cluster to pull images from each other
