Is there any good DoT/DoH DNS resolver that works well in China? I know I can build one myself, but forwarding all DNS requests to my home server in NA slows down all connections...
Unlikely, I'd say. If you fail to upgrade when a new release is made, are they at fault?
You'd need to look towards providers that specifically take on more responsibility like https://compliantkubernetes.com/ (disclaimer: I have worked at Elastisys, the company behind Compliant Kubernetes).
No, although it might reduce your effort needed. AWS offers that responsibility shift under the Fargate ECS/EKS launch types, which might run this underneath.
I haven't written a blog, but I do have a 5 node RaspberryPi cluster running Docker Swarm. The docker stacks and compose files are on GitHub https://github.com/jmb12686/raspi-docker-stacks
Look at the 'gluster' branch for my current active work on clustered persistent storage using SSDs and docker volume plugins.
I have setup quite a few GitHub projects for building / publishing multiarchitecture ARM compatible images of open source projects (Elasticsearch, Kibana, CAdvisor, etc). Check them out if interested in running common tools on RaspberryPis.
The big difference is my setup doesn’t require another email service. Just 10 lines in a config to spin up an imap server. I was trying avoid the big mail providers when I set this up.
