OpenShift

To use slackin on OpenShift, follow these instructions:

1. Create your OpenShift account and install their client tools

2. Create a new OpenShift application for slackin:

rhc app-create slackin https://raw.githubusercontent.com/kyrylkov/openshift-iojs/master/metadata/manifest.yml

1. Identify the following variable values:

• SLACK_SUBDOMAIN: Your Slack's subdomain (the this part in this.slack.com),
• SLACK_API_TOKEN: A Slack API token (find it on https://api.slack.com/web)
• SLACK_CHANNELS (optional): Comma-separated list of single guest channels to invite them to (leave blank for a normal, all-channel invite). In order to make this work, you have to have a paid account. You'll only be able to invite as many people as your number of paying members times 5.

And set them for the app using:

rhc env-set -a slackin SLACK_API_TOKEN="$SLACK_API_TOKEN" SLACK_SUBDOMAIN="$SLACK_SUBDOMAIN" SLACK_CHANNELS="$SLACK_CHANNELS"

1. If you'd like a custom domain, run:

rhc alias-add $SLACK_CUSTOM_DOMAIN -a slackin

Where $SLACK_CUSTOM_DOMAIN is something like slack.bevry.me where bevry.me is your domain name. Then create CNAME record with your DNS host pointing slack.YOUR_DOMAIN.COM to slackin-YOUR_OPENSHIFT_NAMESPACE.rhcloud.com

1. Deploy slackin to your app:

git clone https://github.com/balupton/slackin.git -b feature-openshift
cd slackin
git remote add openshift `rhc app-show slackin | grep Git | sed 's/^.*ssh/ssh/'`
git push openshift feature-openshift:master --force
cd ..
rm -Rf slackin

1. You should be all good now! Check the logs of your app with:

rhc tail -a slackin
