Create a node cohort

A node cohort defines skills and settings installed on every node in a cohort.

After you create a cohort, you assign nodes to the cohort during node enrollment, and Chef 360 Platform installs or removes the skills and settings on every node accordingly.

Prerequisites

• Override settings are defined.

Create a node cohort

To create a node cohort, follow these steps:

1. Create a file named node-cohort.json that contains the skill assembly ID and the settings ID it should be associated to.

   {
     "name": "node-cohort-mchef",
     "description": "Description first cohort",
     "settingId": "5b305ea5-c89b-4ac3-a471-60dadf4980ed",
     "skillAssemblyId":"4ecbe415-838a-4446-abc1-9c57de9211d8"
   }
   

2. Create the node cohort:

   chef-node-management-cli management cohort create-cohort --body-file node-cohort.json --profile <NODE_MANAGER_PROFILE_NAME>
   

   {
   "item": {
       "cohortId": "86628101-0f31-48aa-b035-a8889232e568"
     }
   }
   

   The above command returns a response containing the cohortId. Save it for using during Node Enrollment.

Troubleshooting

• Verify that the node cohort was created successfully:

  chef-node-management-cli management cohort find-one-cohort --cohortId <COHORT_ID> --profile <NODE_MANAGER_PROFILE_NAME>

• See the documentation on managing node cohorts.
