Discourse on Openshift

Installer and action hooks for Discourse on Openshift. Includes scripts to install Ruby 2.0.0-p0 with rbenv.

Step by Step

01. Build the Discourse Gear

Create

These are the contents of my 'rhccreate.bash' file:

un=whoever
openshiftpwd=whatever
appname=discourse

set -x

export GIT_MERGE_AUTOEDIT=yes

rhc setup  -l $un -p $openshiftpwd --create-token
ssh-keyscan -H rhcloud.com >> ~/.ssh/known_hosts

# Create App
rhc app create $appname diy-0.1 -l "$un" -p "$openshiftpwd" || exit 1 | tee ~/openshiftappbuild.txt

rhc cartridge add postgresql-9.2 -a $appname | tee -a ~/openshiftappbuild.txt
rhc add-cartridge http://cartreflect-claytondev.rhcloud.com/reflect?github=smarterclayton/openshift-redis-cart -a $appname | tee -a ~/openshiftappbuild.txt

Alternatively, if you've already built the Gear, you can just clone it:

rhc git-clone -a discourse

Configure

cd discourse

git remote add upstream -m master git@github.com:NeilBryant/discourse-quickstart-neb.git
git pull -s recursive -X theirs upstream master

Before deployment update config/environments/production.rb.openshift with valid SMTP credentials.

In mycase, I use this command from the host PC:

scp -F tmp/vagrant-ssh-config tmp/production.rb.openshift  default:~/discourse/config/environments/production.rb.openshift

git rm the 1.* file you don't need. Also git rm the README.md file.

Now deploy it to the Openshift Gear:

git push

02. Login to the Gear

rhc ssh -a  discourse

Openshift doesn't have a lot in the way of modifying your environment. The script configures an environmnt variable to use as a shortcut; so to start rbenv in your new ssh session, type:

$rinit

Make sure the version is correct, and install bundler:

ruby --version
gem install bundler

03. More Git Work (local)

git commit -a -m "Added Openshift hooks."
git remote add discourse git@github.com:discourse/discourse.git
git pull -X ours discourse master

~~git fetch discourse~~

Either decide on a release, or go with the latest.

~~git checkout -b mergetemp v0.9.7.3
or
git checkout -b mergetemp latest-release
git checkout master~~

Summary

My current build steps are:

cd discourse
git remote add upstream -m master git@github.com:NeilBryant/discourse-quickstart-neb.git
git pull -s recursive -X theirs upstream master
git rm 1.install-rbenv
git rm README.md
git commit -a -m "Removed rbenv"
git commit -a -m "Added production.rb"
git push

Go log on (probably don't need this if you yank the discourse rakefile call)

git remote add discourse git@github.com:discourse/discourse.git
git pull -X ours discourse master
git pull -s recursive -X theirs upstream master
git push

Log on. Manually:

$rinit
ruby --version
\# ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-linux]
gem --version
\# 1.8.28
cd app-root/repo
gem install bundler
gem install libv8
gem install therubyracer
bundle install  --no-deployment

This is because libv8/therubyracer doesn't seem to install in As an alternate, you might try changing the Gemfile to rubyracer 0.10.x before git pushing it.

When the system runs out of space, run this:

#!/bin/bash

# For bundle install --no-deployment
cachedir=~/app-root/data//.rvm/gems/ruby-1.9.3-p125/cache
sourcedir=~/app-root/data//.rvm/gems/ruby-1.9.3-p125/gems

# For bundle install --deployment
# cachedir=~/app-root/repo/vendor/bundle/ruby/1.9.1/cache
# sourcedir=~/app-root/repo/vendor/bundle/ruby/1.9.1/gems

for f in $cachedir/*.gem
do
  echo "Processing $f file..."
  # take action on each file. $f store current file name
  # This would keep the path intact...
  # rm -rf ${f/.gem/}
  rm -rf $sourcedir/`basename "$f" .gem`
done

rm -rf ~/app-deployments/2*
rm -rf ~/app-deployments/2013-11-25_01-25-59.907/
