Hi everyone, as mentioned in chat yesterday, Docker will limit the number of layers a user can pull within 6 hours:
https://www.docker.com/blog/scaling-docker-to-serve-millions-more-developers-network-egress This will certainly cause problems for people pulling our images from the Docker Hub. Especially in Kubernetes scenarios where ImagePullPolicy=Always is common practice and often even enforced by running the AlwaysPullImages admission controller. This will likely lead to outages in dynamic environments (autoscaling, spot instances etc). I'd expect especially the node-exporter to be affected since it's probably the thing people run the most instances of in their infrastructure. There is not much we can do. We could beg Docker to void the limits for us but I think the best option we have is to let our users know about the limitation and suggest using quay.io instead. I've already submitted a PR[1] to remove all references to Docker Hub from the node-exporter repo (We already used quay in our README example). I suggest we do the same for all other components. 1) https://github.com/prometheus/node_exporter/pull/1825 -- You received this message because you are subscribed to the Google Groups "Prometheus Developers" group.
