Register Node Management agent

The Node Management agent manages skills on a node. You must define settings on the Node Management agent before defining skills and override settings that are installed on nodes.

Prerequisites

• CLIs are installed and registered.

Register the Node Management agent

To register the Node Management agent, follow these steps:

1. Create a file named register-agent-skill.json that defines the Node Management agent settings:

   {
   "bldrUrl": "<HABITAT_BUILDER_URL>",
   "bldrChannel": "<CHANNEL>",
   "bldrAuthToken": "<TOKEN>",
   "nodeCheckinInterval": <CHECK_IN_INTERVAL>,
   "updateSkillMetadataInterval": <UPDATE_SKILL_INTERVAL>,
   "logLevel": "<LOG_LEVEL>"
   }
   

   Replace:

   • <HABITAT_BUILDER_URL> with the Chef Habitat Builder URL. Use https://bldr.habitat.sh for Chef’s Habitat Builder or the URL of your own Habitat Builder deployment.

   • <CHANNEL> with the release channel from which to install skills. For example, stable.

   • <TOKEN> with the authentication token for Habitat Builder. If you’re using Chef’s Habitat Builder, set this to an empty string.

   • <CHECK_IN_INTERVAL> with the interval (in seconds) at which check-in occurs. Value starting from 3600 (1 hour).

   • <UPDATE_SKILL_INTERVAL> with the interval (in seconds) at which skill definitions are updated. Value starting from 3600 (1 hour).

   • <LOG_LEVEL>: The logging level of the agent. For example, debug.

     Supported log levels:

     debug

     Reports detailed information that can aid in identifying issues or debugging a workload. This includes the info, warn, and error logs.

     info

     Reports general information about the system’s operations.

     warn

     Reports potential failures, but the operation can continue functioning for the time being.

     error

     Reports errors that prevent the execution of an operation.

2. Create the skill assembly:

   chef-node-management-cli management skill update-agent --body-file register-agent-skill.json
   

   It returns the following response:

   {
    "code" : 200,
    "message" : update-agent successful
   }
   

Next step

• Create skill definitions.
