OpenShift V3 Generic WebHook Tag

I’m trying to understand how to provide a Docker image tag that will be included with the image pushed to my private Docker registry when a webhook call is made to OpenShift v3. The overall process of having Git commits initiate the build, image, and registry push are all fine. They are initiated by the […]

Slow network in Docker container after OpenShift install

After installing CentOS 7 VM in Google Cloud (n1-standard-2) with CentOS’ own Docker packages (docker-1.10.3-44) the network performance is as expected.

However if the same node is part of an OpenShift Origin (1.1) installation (with default network settings wherever applicable), the […]
