@abitrolly check this http://phusion.github.io/baseimage-docker/
Let me clarify - this setup is for full blockchain nodes?
I need to get more info about what type of workload to expect from these nodes? Optimizing network stack for 300.000 concurrent connections may be not as worthy as more CPU cycles to query blockchain itself.
autotune
looks reasonable. Let's setup monitoring first to check that those IPv4 settings really matter.
I am checking what are the best practices to keep containers up to date with security updates in base images - https://stackoverflow.com/questions/26423515/how-to-automatically-update-your-docker-containers-if-base-images-are-updated
And so we also need to decide what would be the base image. 16.04 LTS or 17.04 or something more exotic? I am comfortable with 17.04 though.
@abitrolly LTS version, and yes, full blockchain nodes, but directories with chain data should be mounted
Where are those storage mounts physically and logically located?
Meeting notes. Blockchain data is mounted to /data
point inside container and physically located on the host that runs the full node container for now.
Need monitoring to add current nodes to it to gather requirements. Variants:
PROS: Easy to install. Graphs are inside DO control panel, easily accessible by everyone with login. CONS: Participation in their data collection policy is not an opt-in. Not clear if the monitoring will work with hardware deployed nodes. https://www.digitalocean.com/community/tutorials/an-introduction-to-digitalocean-monitoring
Metrics that is needed right now:
Metrics specific to blockchain workload:
@abitrolly research this please https://github.com/cusspvz/autotune.docker
