If your platform requires the entity container map, you can provide a json file of the format:

[
  {
     "id" : 1,
     "containerEntityId" : 2,
     "containerEntityInstance" : 3,
     "isList" : false,
     "isLinked" : false,
     "entities" : [
         {"id" : 1, "instance" : 2},
         {"id" : 1, "instance" : 3},
         {"id" : 1, "instance" : 4},
         {"id" : 1, "instance" : 5}
     ]
  }
]

as part of your phosphor-ipmi-config

The above json is identical to the original YAML documented below:
