In this video, Veer Muchandi covers integrated A/B Deployments and how to test application changes in OpenShift Container Platform 3.3.
Notes
Steps to run an A/B test on OpenShift Container Platform 3.3
- Using the OpenShift web console create a new-app with name
app-a
. Go to the advanced options and uncheck the route creation option so that the app does not create a route. We will add the route later. - Add a route by clicking on the
Create Route
option next to serviceapp-a
. Give a common name for the route as it will frontend multiple versions of the application (e.g. appab-abdemo.apps.testv3.osecloud.com). - Annotate the route to use roundrobin load balancing method:
oc annotate route/appab haproxy.router.openshift.io/balance=roundrobin
- Test your app and check the results.
- Edit the code to make some changes.
- Using the web console add a new-app with name
app-b
without a route. Verify that serviceapp-b
was created. - Now edit the route to split traffic between services
app-a
andapp-b
. You can change the percentages and test. - Test using curl from your workstation - for example:
for i in {1..20}; do curl http://appab-abdemo.apps.testv3.osecloud.com/; echo ""; done
