##################################################################################
#
# The goal of this script is to allow quick setup of a blank local multi node
# cluster for development testing without needing to erase or interfere with
# previous testing. It also enables redeployment of the code for such testing
# clusters without erasing the data previously indexed.
#
# It is for dev testing only NOT for production use.
#
# This is also NOT meant to be run from this directory within a lucene-solr
# working copy. Typical usage is to copy it out to a separate workspace
# such as (<GIT_CHECKOUT>/../testing) and edit then either use the -w option
# or edit the definition of DEFAULT_VCS_WORKSPACE variable below.
#
# Usage:
# ./cloud.sh <command> [options] [name]
#
# Options:
# -c clean the data & zk collections erasing all indexed data
# -r recompile server with 'ant clean server create-package'
# -m <mem> memory per node
# -a <args> additional JVM options
# -n <num> number of nodes to create/start if this doesn't match error
# -w <path> path to the vcs checkout
# -z <num> port to look for zookeeper on (2181 default)
#
# Commands:
# new Create a new cluster named by the current date or [name]
# start Start an existing cluster specified by [name]
# stop stop the cluster specified by [name]
# restart stop and then start
#
# In all cases if [name] is unspecified ls -t will be used to determine the
# most recent cluster working directory, and that will be used. If it is
# specified it will be resolved as a path from the directory where cloud.sh
# has been run.
#
# By default the script sets up a local Solr cloud with 4 nodes, in a local
# directory with ISO date as the name. A local zookeeper at 2181 or the
# specified port is presumed to be available, a new zk chroot is used for each
# cluster based on the file system path to the cluster directory. the default
# solr.xml is added to this solr root dir in zookeeper.
#
# Debugging ports are automatically opened for each node starting with port 5001
#
# Specifying an explicit destination path will cause the script to
# use that path and a zk chroot that matches, so more than one install
# can be created in a day, or issue numbers etc can be used. Normally the
# directories containing clusters created by this tool are in the same
# directory as this script. Distant paths with slashes or funny characters
# *might* work, but are not well tested, YMMV.
#
# PEREQ: 1. Zookeeper on localhost:2181 (or as specified by -z option) where
# it is ok to create a lot of top level directories named for
# the absolute path of the [name] directory (for example:
# /solr_home_myuser_projects_solr_testing_2019-01-01) Note
# that not using the embedded zookeeper is key to being able
# switch between testing setups and to test vs alternate versions
# of zookeeper if desired.
#
# SETUP: 1. Place this script in a directory intended to hold all your
# testing installations of solr.
# 2. Edit DEFAULT_VCS_WORKSPACE if the present value does not suit
# your purposes.
# 3. chmod +x cloud.sh
#
# EXAMPLES:
#
# Create a brand new 4 node cluster deployed in a directory named for today
#
# ./cloud.sh new
#
# Create a brand new 4 node cluster deployed in a directory named SOLR-1234567
#
# ./cloud.sh new SOLR-1234567
#
# Stop the cluster
#
# ./cloud.sh stop
#
# Compile and push new code to a running cluster (incl bounce the cluster)
#
# ./cloud.sh restart -r
#
# Dump your hoplessly fubar'd test collections and start fresh with current tarball
#
# ./cloud.sh restart -c
