Assign nodes to environments via an ENC

You can assign agent nodes to environments by using an external node classifier (ENC). By default, all nodes are assigned to a default environment named production.

The interface to set the environment for a node is different for each ENC. Some ENCs cannot manage environments. When writing an ENC:

  1. Ensure that the environment key is set in the YAML output that the ENC returns. If the environment key isn’t set in the ENC’s YAML output, the primary server uses the environment requested by the agent.

The value from the ENC is authoritative, if it exists. If the ENC doesn’t specify an environment, the node’s config value is used.
