RD2L Ladder deploy on OpenShift

---

1. Create project on openshift:

oc new-project rd2l

2. Create ladder app from github source:

oc new-app https://github.com/UncleVasya/Dota2-EU-Ladder --name=ladder

3. If you get Error 137 during build, you need to increase memory limit in buildconfig.

   Edit YAML for buildconfig (and deployconfig if first doesn't help):

   spec:
       resources:
   	limits:
   	    memory: "1Gi"
   

   or use console version:

   • buildconfig:

   oc.exe  patch bc/ladder --patch "{\"spec\":{\"resources\":{\"limits\":{\"memory\":\"1Gi\"}}}}"
   

   • deployconfig:

   oc.exe  patch dc/ladder --patch "{\"spec\":{\"resources\":{\"limits\":{\"memory\":\"1Gi\"}}}}"
   

4. Add persistent storage for database:

oc set volume dc/ladder --add --name=data --claim-name=ladder-data --type pvc --claim-size=1Gi --mount-path /opt/app-root/src/data

5. Expose app for web requests:

oc expose svc/ladder

Or create Route in web console manually.

At this point you should be able to visit ladder web interface.

6. Create superuser. Open running pod in a terminal and run:

python manage.py createsuperuser

7. Add environment vars to DeployConfig:

BOT_LOGIN=euladder_bot
BOT_PASSWORD=****
LOBBY_PASSWORD=****
LEAGUE_ID=****
DISCORD_BOT_TOKEN=****
BASE_URL=https://inhouse.rd2l.eu

Hints for local development on Windows:

1. In .virtualenv\Scripts\activate.bat set env variables:

set "BOT_LOGIN=euladder_bot"
set "BOT_PASSWORD=****"
set "LOBBY_PASSWORD=****"
set "LEAGUE_ID=****"
set "DISCORD_BOT_TOKEN=****"

2. If wokring from PyCharm, its terminal won't have these variables set by default. You need to deactivate / activate virtualenv manually:

.virtualenv\Scripts\deactivate.bat
.virtualenv\Scripts\activate.bat
