Improve ~remote~ _playbook_ instructions.

[rosiel]

Purpose / why

The instructions are outdated! We no longer need karaf or so many fedora uris.

What changes were made?

• removed deprecated options
• updated the sample new folder name from example to production to give it more realism and also to match the command at the bottom

Verification

Can you use this to provision a ubuntu 20.04, and get all the expected behaviours?

Current issues:

1. Can't index into Fedora. After playbook running, there are ~32 messages dequeued from the islandora-indexing-fcrepo-content, but once i expose the Fedora interface (see below) i see none of them are in Fedora. The fcrepo/rest interface shows an empty repository with no "children".

The method I used to open Fedora was the "alternatively" fcrepo.xml file approach here: https://wiki.lyrasis.org/display/FEDORA6x/Disable+Authentication+and+Authorization. Once this has been done, i see new "children" in Fedora when i add content in Drupal. This definitely isn't a step i need to take in Vagrant (for indexing OR for access at :8080), but I'm not sure why. By the time I checked (the playbook had finished) the admin user had fedoraAdmin role.

Here's a sample of (one node's worth of) errors in milliner log.

2. Known issue, affects Vagrant too: We're putting messages to islandora-indexing-fcrepo-file-external but nothing is reading them: the "Number of Consumers" is 0.

3. FITS isn't ... working? Using both the automatic Contexts and the Action to create FITS derivatives, I get nothing back. The messages are being dequeued from the ActiveMQ. There's an auth error in the alpaca logs. See error log snippet.

I don't see any lines marked with ERROR in the milliner log snippet you referenced. Is there more after? Also it would be good to see what the Fedora log is saying too.

[rosiel]

I tried a fresh server and the milliner problems didn't happen (Also, wow I think I failed to copy the wrong section of those logs!)

Fits is kind of a different thing, so i'm investigating that separately, but it probably doesn't have to do with the remote deployment instructions.

[rosiel]

don't worry the rest of the passwords are there on the right... just bumped down in the diff.

[rosiel]

This was breaking cantaloupe, hat-tip to @whikloj for helping find the solution.

[ysuarez]

Is this ready for merging, do we need a final person besides Rosie to give it a final "blessing" before we merge?

[rosiel]

Sorry for the last minute changes - we just updated the interface for using the Playbook so I put the new info here.

[rosiel]

I've deleted the sneaky files that I added by mistake (thanks whoever pointed it out!).
