Decommission ol-home

[cdrini]

Our old ol-home server has an nginx running that proxies to ol-home0. We likely don't need this anymore? But if I recall correctly, when we tried to update all our docker containers to point to ol-home0, something didn't work. Investigation needed.

To close:

• 1) check all occurrences of ol-home in olsystem and openlibrary. Change any occurrence of ol-home:7000 to ol-home0:7000.
  • git grep ol-home --> All instances are ol-home0 except file docker/ol-home-start.sh which looks OK.
  • Investigate if we can remove stats_solr #4426
  • Remove unused process_stats options/methods #7816 (pull request)
  • internetarchive/olsystem#122
  • internetarchive/olsystem#178
  • internetarchive/olsystem#180 Done in the cron-jobs Docker container.
  • Deprecate stats_solr and any of its code #7817
  • internetarchive/olsystem#174
• 2) Patch Deploy this to our servers as a test and restart docker containers one by one (See deployment guide). If everything works, woohoo! Test borrowing/editing works.
• 3) Try removing the proxy in olsystem/etc/nginx/sites-available/infobase.conf on the old server ol-home (see git diff in that server/repo) and restarting nginx on that server. If everything works, woohoo! We're done.

  • Undid because of All create/update/delete operations broken #7920

Why is macOS Control Center listening on ports 5000 and 7000? https://developer.apple.com/forums/thread/682332

I expect Apple to switch to less controversial ports in the future but if other macOS users bump into this, they can disable AirPlay Receiver to get access to port 7000.
