Fields:

• 'updateBroker' - will enforce cf borker-update
• 'containers' - list of kubernetes containers - definition
• 'servicePorts' - list of ports which will be assigned to kubernetes service - definition. This is a simple mapping, where 'port' value refers to 'containerPort' value
• 'credentialMappings' - map of envs which will be serve to other apps. To put there container env value, following pattern has to be fulfill: 'env_ENV_NAME'. Service NodePort value also can be use. To access it use pattern: 'port_PORT_NUMBER'
