zanata-deploy.sh

#!/bin/bash -ex

# Script: zanata-deploy.sh
# Authors: sflaniga@redhat.com, camunoz@redhat.com

# This script deploys zanata.war from the local Maven repo
# to a target machine, based on a Jenkins job name
# and some configuration variables read from ~/.config/zanata-deploy.conf.

# Requirements:

# 1. env var WARNING_EMAIL must be set via zanata-deploy.conf
# 2. Jenkins vars BUILD_TAG, JOB_NAME, GIT_BRANCH set by Jenkins
# NB Jenkins will only set $GIT_BRANCH if the build config specifies a single branch
# 3. Jenkins job name should look like zanata-VER-PROFILE or zanata-build-deploy-VER-PROFILE
# 4. set m2repo or srcdir if you want to override defaults
# 5. minimal zanata-deploy.conf should look something like this:
#
# master_version=1.5
# host_1_4_jaas=jaastest.example.com
# host_1_4_internal=internaltest.example.com
# NB replace . with _ in variable names

# Each target box should be set up in a certain way.  
# See the default values for url, user, service and targetfile near the
# end of this script, or override them for each affected host, eg:
# host_1_5_special=specialcase.example.com
# url_1_5_special=https://specialcase.example.com/
# user_1_5_special=jenkins
# service_1_5_special="sudo /etc/init.d/jbossas"
# targetfile_1_5_special="/opt/jboss-as/server/default/deploy/ROOT.war"
