The Node Manager profile is an abstraction for the amount of resources a Node Manager advertises to the Resource Manager. These profiles are set in the Myriad configuration file, myriad-config-default.yml. Each profile is identified by zero, small, medium, and large with default CPU and memory parameters. The cluster can be configured to start with a initial number of Node Managers. By default, Myriad requires at least 1 NM instance with a medium profile. See Myriad Cluster API for information about flexing up or down an instance.

During initial startup, Myriad launches one NodeManager instance with a profile of medium through the parameter, nmInstances, which is specified in the myriad-config-default.yml file.

"nmInstances": {

    "medium": 1

  },


The following default profiles are configurable. To change a profile, modify the Myriad configuration file, myriad-config-default.yml. 

If you modify the Myriad configuration file after the initial build, you must build and deploy again for the changes to take affect.

Default profiles:

"profiles": {
  "zero": {
    "cpu": "0",
    "mem": "0"
  },
  "small": {
    "cpu": "1",
    "mem": "1100"
  },
  "medium": {
    "cpu": "2",
    "mem": "2048"
  },
  "large": {
    "cpu": "4",
    "mem": "4096"
  }
},
