Issue/Introduction

We are trying to do a offline install of DX APM 21.3 in Openshift 4.7 as namespace administrators and the namespace we are trying to install in is called "dxapm".
We get to the question "Specify your custom prefix for docker images or press enter to use the default prefix." and after that the install is interrupted by a java error:

[cluster-info] ConfigMap dxi-cluster-info not found in dxapm namespace
Application run failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'consoleEntryPoint': Invocation of init method failed; nested exception is com.ca.dxi.exception.ClusterAccessException: Cluster user doesn't have cluster level access and cache not available in selected namespace

 

The full exchange below:

[[email protected] dxapm]# CUSTOM_ENV_VARIABLES="-e PRIVILEGED_CONTAINERS_DISABLED=true" ./AIOpsManagement.sh --install

Resolution

The user used for installing was missing some required cluster privileges, after setting it up accordingly the problem was addressed.
