Random Recent IT "stuff"

General issues
  • Ubuntu 21.04 upgrade
    • sizing tmpfs - default 36G on my system seems excessive; what was eating up memory/swap the other day
  • Rootless Docker push to Microk8s Registry
    •  Get https://docker-star-cases:32000/v2/: dial tcp: lookup docker-star-cases on <x.y.z.q>:53: server misbehaving
    • What about podman, buildah, etc? 
  • Microk8s 1.21.0 upgrade
    • kubelite - somewhat excessive CPU?
  • DNS
    • Still working out some DNS ideas
  • journal 
    • logging tuning 
  • Routing / firewall tuning

 

Other known challenges

  • sorting out my nvme and ssd partitions and best usage
    •  Careful not to conflict with snap or normal ubuntu upgrades

Potential plans

  • Upgrade to 128G RAM
    • Allow creation of some specific ramdisks to minimize wear on nvme/ssd drives.
  • Upgrade to i9 processor
    • More cores/threads to spread the services over.
  • Commercial or self-built NAS
    • Simplify data management and provide high-speed access to more systems.
  • UI work

In-progress / todo

  • setup bitnami/openldap in Microk8s
    • enable tls / cert rotation
  • some oauth2 related selections
  • App integration with geoserver 
  • Catch-up Graalvm version of services with SpringBoot version
