The New Relic Developer Toolkit offers a suite of tools to reduce development toil, including a Kubernetes Operator that provides a seamless way to deploy New Relic resources alongside Kubernetes deployments. The operator follows the control loop pattern and allows developers to configure their New Relic monitoring resources using the same configuration files as their other Kubernetes configurations. To use the operator, developers must first install it in their Kubernetes cluster, which involves installing cert-manager and running kustomize commands. Once installed, developers can create and manage New Relic alert policies and NRQL alert conditions using kubectl apply commands. The operator provides a declarative approach to creating alert policies, allowing developers to write configuration files that define the desired behavior of their alert policies. With the operator, developers can automate their workflows and gain consistency and maintainability in their alert configurations.
