Kopf —Kubernetes Operator Pythonic Framework— is a framework and a library to make Kubernetes operators development easier, just in few lines of Python code.
The main goal is to bring the Domain-Driven Design to the infrastructure level, with Kubernetes being an orchestrator/database of the domain objects (custom resources), and the operators containing the domain logic (with no or minimal infrastructure logic).
Akrobateo is a universal load balancer service implementation for Kubernetes. Akrobateo can work in any environment which makes it suitable for many use cases. And it's super light-weight too. It is implemented as an operator that reacts when it sees type: LoadBalancer services in the cluster.
KubePlus Platform toolkit simplifies discovery and use of Kubernetes Operators and Custom Resources in a cluster.
Kubernetes Custom Resource Definitions (CRDs), popularly known as Operators, extend Kubernetes to run and manage third-party software directly on Kubernetes. Today, number of Operators are being built for middlewares like databases, queues, ssl certificates, etc. The Custom Resources introduced by Operators essentially represent 'platform elements' as their Spec definitions encapsulate some higher-level workflow actions on the underlying infrastructure resource that they are managing (database, queue, ssl certificate, etc.). A novel approach for building platforms on Kubernetes is to construct a platform stack from multiple Custom Resources, essentially building platforms as Code.
Platform as Code approach provides true portability across Cloud providers as your entire platform stack is running on Kubernetes. It also enables Kubernetes YAML to become common language between Operations team and application development teams.
Terraform-operator - This is a low level tool to run Git controlled Terraform modules in Kubernetes. The operator manages the TF state file using Kubernetes as a remote statefile backend! Backend upstream PR You can have changes auto-applied or wait for an explicit "OK" before running.
Kubernetes External Secrets allows you to use external secret management systems (e.g., AWS Secrets Manager) to securely add secrets in Kubernetes
An open source, git-ops, zero-trust secret encryption and decryption solution for Kubernetes applications - Soluto/kamus
This controller will continuously watch ingresses/routes in specific or all namespaces, and automatically add / remove monitors in any of the uptime checkers. With the help of this solution, you can keep a check on your services and see whether they're up and running and live, without worrying about manually registering them on the Uptime checker.
Operator for creating and managing instances of Weaveworks flux, helm-operator and tiller, the cluster component of Helm.
Maestro provides a declarative approach to building production-grade Kubernetes Operators covering the entire application lifecycle.
Multicluster-controller is a Go library for building Kubernetes controllers that need to watch resources in multiple clusters. It uses the best parts of controller-runtime (the library powering kubebuilder and now operator-sdk) and replaces its API (the manager, controller, reconcile, and handler packages) to support multicluster operations.
Fully automated, policy driven continuous deployment solution for Kubernetes Keel
KubeDirector uses standard Kubernetes (K8s) facilities of custom resources and API extensions to implement stateful scaleout application clusters. This approach enables transparent integration with K8s user/resource management and existing K8s clients and tools.
kooper - Kooper is a simple Go library to create Kubernetes operators and controllers.
operator-kit - A library for creating a Kubernetes Operator
Stash by AppsCode is a Kubernetes operator for restic. If you are running production workloads in Kubernetes, you might want to take backup of your disks. Traditional tools are too complex to setup and maintain in a dynamic compute environment like Kubernetes. restic is a backup program that is fast, efficient and secure with few moving parts. Stash is a TPR controller for Kubernetes built around restic to address these issues
Searchlight by AppsCode is a Kubernetes operator for Icinga. If you are running production workloads in Kubernetes, you probably want to be alerted when things go wrong. Icinga periodically runs various checks on a Kubernetes cluster and sends notifications if detects an issue. It also nicely supplements whitebox monitoring tools like, Prometheus with blackbox monitoring can catch problems that are otherwise invisible, and also serves as a fallback in case internal systems completely fail. Searchlight is a TPR controller for Kubernetes built around Icinga to address these issues.
