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" } },
