Jan Høydahl commented on SOLR-13035:
------------------------------------
Looks scary to do {{SOLR_LOGS_DIR="$(pwd)/$SOLR_LOGS_DIR"}}. It would be better
to require user to configure absolute path here.
Why are you changing the default location of logs from SOLR_TIP/server/logs to
SOLR_HOME/logs, i.e. SOLR_TIP/server/solr/logs? Also the installer script
explicitly configures SOLR_LOGS_DIR to /var/solr/logs, and not to
/var/solr/data/logs as would be the equivalent if it belongs inside SOLR_HOME?
I agree on the goal of making Solr more container friendly and clearly separate
what paths can be made R/O and what paths typically need a separate volume
mounted. Can you perhaps create a diagram that clearly shows the various
directory paths we have today with their defaults and how they will be changed?
While I believe solr.xml could be created if not exist, I'm no so sure we
should go create SOLR_DATA_HOME if it does not exist?
In general, I'd prefer of much of the logic regarding folder resolution etc was
done in the common {{SolrCLI.java}} so as little logic as possible needs to be
duplicated in bin/solr and bin/solr.cmd

> {{solr.data.home}} system property or {{solrDataHome}} in _solr.xml_ is
> already available as per SOLR-6671.
> The writable content in Solr are index files, core properties, and ZK data if
> embedded zookeeper is started in SolrCloud mode. It would be great if all
> writable content can come under the same directory to have separate READ-ONLY
> and WRITE-ONLY directories.
> It can then also solve official docker Solr image issues:
