Minimum Updates for percli to run peregrine on Sling 12 based instance

[cmrockwell]

Corresponding to a Sling 12 based launcher, percli needs a few changes.

1. --sling or -s is the sling version. There needs to be an option for 12 https://github.com/headwirecom/percli/blob/master/bin/percli-server-install#L42

2. Sling 12 needs a launcher (org.apache.sling.feature.launcher.jar) and feature aggregate (feature-oak_tar.json). I presume those need to be hosted on headwire's vagrant. and referenced in https://github.com/cmrockwell/peregrine-cms/blob/upgrade/sling12-PM-Java11/docker/scripts/start.sh

3. Run modes and TCP port previously set in sling/sling.properties need to be set using launcher framework properties -D properties. For example: java -jar org.apache.sling.feature.launcher.jar -f feature-oak_tar_fds.json -D sling.runmodes=author,notshared,oak_tar,fds -p sling

@cmrockwell I am wondering if we want to push 2) to github instead - it could make sense to have these files on https://github.com/peregrine-cms with a repo to build and publish the latest version to decouple this headwire dependency

[cmrockwell]

@reusr1 That sounds like a great idea

Another thing to think about is how start and stop scripts will work without support for sling.properties and without a Starter jar that takes 'start', 'stop' , 'status', or 'threads'

[reusr1]

we may want to consider the sling kickstarter for peregrine instead of launching a feature model directly. After all that's what it was written for

https://sling.apache.org/documentation/feature-model/howtos/kickstart.html

[cmrockwell]

Kickstart is either not working or I'm doing it wrong. I'm testing it with the script below, and have some issues:

• Install Run Mode Options are not taking effect. In the short run, we need runmodes until they can be refactored into feature files.
• Sling Home is not properly defined. Using either -c or --slingHome doesn't matter. Either way results in two homes "launcher" and "sling."
  • ls launcher shows folders: framework logs repository resources
  • ls sling shows folders: conf repository
• In the test below, 127.0.0.1:50500 is specified control port. Using this to check status, doesn't work
  • java -jar ../org.apache.sling.kickstart-0.0.2.jar --control=127.0.0.1:50500 status

Ideas?

In the short run, my project start.sh will probably look more like this one. which is basically the same way as @GastonGonzalez 's DockerFile setup. This avoids certain issues mentioned above, and matches the way I've been running and testing locally. Though I could see switching to Kickstart after the initial merge.

I created this issue to add support for the Kickstarter. Once this ticket is resolved, I'll take this ticket.
