 The Kubernetes APM auto-attach, formerly known as the Kubernetes agent operator, streamlines full-stack observability for Kubernetes environments by automating APM instrumentation alongside Kubernetes agent deployment. By enabling <InlinePopover type="APM"/> auto instrumentation, developers no longer need to manually manage [APM agents](/docs/apm/new-relic-apm/getting-started/introduction-apm/). The Kubernetes APM auto-attach will automatically install, upgrade and remove APM agents.

   You can add more expressions to the selector. As in the example, each expression must contain a key, an operator, and possibly (depending on the operator) a list of values. There are four valid operators:
-  
+
   * `In`: Label's value must match one of the specified values.
   * `NotIn`: Label's value must not match any of the specified values.
   * `Exists`: Pod must include a label with the specified key (the value isn't important). When using this operator, you shouldn't specify the values field.

     You can still import and call the agent API to add custom instrumentation into your application. You can also utilize a configuration file or environment variables to add custom instrumentation if the particular agent you're using supports it. Note that agents have order of precendence between configuration via environment variables and configuration via configuration files, so you will need to make sure your environment variable configuration via the operator is not clashing with your configuration via configuration file. See each agents custom instrumentation docs for details:
