Application Build

Platform requirement

  • Zope Python based Application server
  • Python Postgress driver
  • Zope Postgres driver wrapper
  • Postgress Database
  • Database GUI

Migration

Move ularu VM from bukit (to be recovered) to antecessor

  1. Export VM in .ova format
  2. Test on james (final target server)

Importing VM on james

VBoxManage import UbuntuAppServerClean202401.ova --dry-run

VBoxManage import UbuntuAppServerClean202401.ova

VBoxManage list vms

VBoxManage startvm "Ubuntu App Server" --type headless

Waiting for VM "Ubuntu App Server" to power on...

VBoxManage modifyvm "Ubuntu App Server" --nic2 bridged --bridgeadapter1 enp1s0

VBoxManage: error: AMD-V is disabled in the BIOS (or by the host OS) (VERR_SVM_DISABLED)

VBoxManage modifyvm "Ubuntu App Server" --cpus 1

VBoxManage modifyvm "Ubuntu App Server" --paravirtprovider none

Dyn DNS

  • sudo apt install ddclient
  • user; qapps
  • hosts: southern.podzone.net,musings.thruhere.net,qsolutions.endoftheinternet.org,docs.podzone.net,mottttspot.servegame.org,poc.endoftheinternet.org

Data take-on

  • Postgress export from legacy implementation
  • Import into new Postgress instance

Implementation

Zope

  • Initial install of Plone, provides Zope 4, which is not backward compatable with the Zope 2 applications, so use a legacy zope image.

  • Legacy Zope image selected: robcast/legacy-zope:2.13

  • Zope volume mounts: ./var/filestorage; ./var/blobstorage; ./products

Postgres

  • nfs not working for postgres volume, issues with chmod (as with OpenSearch)
  • Use cluster-internal db GUI tool to avoid requirement to provide ingress for a database port.
