What are the supported OLM installations modes by IBM Maximo Application Suite - Watson IoT Platform?

Answer

Below are listed the OLM installation modes supported by IBM Maximo Application Suite - Watson IoT Platform :
  • The operator only supports single namespace deployment also known as OLM Own Namespace Mode.
  • OLM All Namespace Mode - This mode is not supported by this Operator
  • The operator will only watch for resources in its own namespace
  • Multiple instances of the operator can be deployed in a single cluster
  • Multiple installations of IoT can not be deployed in the same namespace
  • Each IoT resource must be deployed into a namespace that matches the expected naming convention of mas-{instanceId}-iot
