  • Kustomize provides a template-free way to customize Kubernetes YAML configurations using overlays and generators without templates. It is ideal for customizing YAML configs for multiple Kubernetes environments like dev, staging, and prod. Engineering teams can define common resources in a base and then apply overlays with patches, variable substitutions, and images per environment.

  • Flux CD enables continuous deployment to Kubernetes through GitOps by syncing Git repositories with Kubernetes clusters. Flux CD enables GitOps for Kubernetes through source control integration. It manages Kubernetes manifests as code and syncs git repo changes to clusters. Flux automates checks, deployments, and updates within clusters.

  • KEDA introduces event-driven scaling to Kubernetes workloads. It integrates with Kubernetes Horizontal Pod Autoscalers and can scale pods based on external metrics from services like databases and message queues (Kafka, RabbitMQ, MongoDB).

Monitoring & Logging

  • Prometheus is a leading open source monitoring and alerting system explicitly designed for Kubernetes environments with native support for metrics. Prometheus auto-discovers Kubernetes pods, services, and nodes to collect metrics seamlessly. Its Kubernetes service discovery integration scrapes metrics from API objects like deployments, jobs, and ingresses. Prometheus alerts can trigger autoscaling and remediation based on Kubernetes events and statuses.

  • Grafana provides an intuitive dashboard interface to visualize metrics collected from sources like Prometheus. It offers out-of-the-box dashboards tailored for monitoring Kubernetes clusters, nodes, deployments, and pods. Users can create custom panels and graphs to build dashboards optimized for their Kubernetes workloads and services. Through dynamic metric visualizations, Grafana helps gain visibility into cluster resource usage, application performance, user activity, and more. Its annotation feature can mark deployment events on graphs.

  • Datadog provides end-to-end observability, including dashboards, alerts, and log management tailored for monitoring Kubernetes clusters and cloud-native apps. It integrates with Kubernetes to collect metrics and logs from containers, pods, nodes, and controllers. It offers out-of-the-box dashboards for Kubernetes monitoring, namespace mapping, cluster troubleshooting, and more. Datadog's Kubernetes autodiscovery enables tracking dynamic changes.

Automation & Configuration

  • Terraform provides robust support for provisioning and managing Kubernetes infrastructure as code. The Kubernetes provider integrates deeply to manage resources like clusters, nodes, ingress, storage, RBAC controls, and more. Terraform modules help configure secure and production-ready Kubernetes setups across providers.

  • Pulumi - takes an infrastructure-as-code approach to Kubernetes using real programming languages like JavaScript, Python, and Go instead of declarative configs. Pulumi's Kubernetes support allows the defining of clusters, configmaps, deployments, and infrastructure in code. It integrates seamlessly with Kubernetes CLI and APIs for full control through code. Pulumi provides flexible abstractions and reuse through packages and libraries.

  • Ansible provides over 500 modules in the Kubernetes collection for automating tasks within clusters. Modules can deploy apps, configure clusters, manage nodes, handle networking, autoscaling, and security. Ansible is agentless, using OpenSSH to connect and leverage the Kubernetes API. Ansible integrates smoothly with Kubernetes tools like Helm, Kubespray, and Terraform. Ansible playbooks and Kubernetes modules enable automated and idempotent management of production Kubernetes infrastructure.
