Trying to install the OpenShift Monitor in our 3.11 OpenShift environment. 

Here is the output from the step where importing the image from Red Hat.

Per DX APM Engineering, this is due to an issue with Red Hat:

Red Hat confirms (1) that is the default CIDR used by the docker daemons, and (2) that this CIDR can be configured in /etc/docker/daemon.json on each cluster node.

Version 3.11 Openshift PODs couldn't connect to the MOM.  This is because OpenShift by default uses 172.17 as the default CIDR for the docker daemons. 

Red Hat provided the steps to alter the default CIDR.



Release : 10.7.0

Component : APM Agents


Change the CIDR per Red Hat guidance.
