Using git-deploy and systemd to deploy Play2 webdsites

README.md

This uses systemd to control a play2 service

I also am including the git-deploy configuration to update and restart the service from a devleopment machine

• play2.service

  The SystemD script Place in /etc/systemd/system/

• after_push

  The after push configuration file goes in /deploy

• before_restart

  The before restart file goes in /deploy

• restart

  The restart file goes in /deploy

Note:

This still requires sbt to be installed on the remote server. I am looking at how to just build everything locally before I push

after_push

#!/usr/bin/env bash
set -e
oldrev=$1
newrev=$2

run() {
  [ -x $1 ] && $1 $oldrev $newrev
}

echo files changed: $(git diff $oldrev $newrev --diff-filter=ACDMR --name-only | wc -l)

umask 002

git submodule init && git submodule sync && git submodule update

run deploy/before_restart
run deploy/restart && run deploy/after_restart

before_restart

systemctl stop play2.service
sbt clean compile stage
