operator-sdk - SDK for building Kubernetes applications

•    Go

The project is currently pre-alpha and it is expected that breaking changes to the API will be made in the upcoming releases. See the design docs for planned work on upcoming milestones.

chaos-mesh - A Chaos Engineering Platform for Kubernetes.

•    Go

This readme and related documentation are Work in Progress. Controller-manager: used to schedule and manage the lifecycle of CRD objects.

awesome-operators - A resource tracking a number of Operators out in the wild.

Operators are Kubernetes native applications. We define native as being both managed using the Kubernetes APIs via kubectl and ran on Kubernetes as containers. Operators take advantage of Kubernetes’s extensibility to deliver the automation advantages of cloud services like provisioning, scaling, and backup/restore while being able to run anywhere that Kubernetes can run. This list is built by the community. Have you built or are you using an Operator that is not listed? Please send a pull request and we will add that Operator to the list.

Litmus - Cloud-Native Chaos Engineering

•    Go

Litmus is a toolset to do cloud-native chaos engineering. Litmus provides tools to orchestrate chaos on Kubernetes to help SREs find weaknesses in their deployments. SREs use Litmus to run chaos experiments initially in the staging environment and eventually in production to find bugs, vulnerabilities. Fixing the weaknesses leads to increased resilience of the system.

sloth - 🦥 Easy and simple Prometheus SLO (service level objectives) generator

•    Go

Meet the easiest way to generate SLOs for Prometheus. Sloth generates understandable, uniform and reliable Prometheus SLOs for any kind of service. Using a simple SLO spec that results in multiple metrics and multi window multi burn alerts.

etcd-operator - etcd operator creates/configures/manages etcd clusters atop Kubernetes

•    Go

Major planned features have been completed and while no breaking API changes are currently planned, we reserve the right to address bugs and API changes in a backwards incompatible way before the project is declared stable. See upgrade guide for safe upgrade process.Currently user facing etcd cluster objects are created as Kubernetes Custom Resources, however, taking advantage of User Aggregated API Servers to improve reliability, validation and versioning is planned. The use of Aggregated API should be minimally disruptive to existing users but may change what Kubernetes objects are created or how users deploy the etcd operator.

vault-operator - Run and manage Vault on Kubernetes simply and securely

•    Go

The basic features have been completed, and while no breaking API changes are currently planned, the API can change in a backwards incompatible way before the project is declared stable. The Vault operator deploys and manages Vault clusters on Kubernetes. Vault instances created by the Vault operator are highly available and support automatic failover and upgrade.

elasticsearch-operator - manages elasticsearch clusters

•    Go

The ElasticSearch operator is designed to manage one or more elastic search clusters. Included in the project (initially) is the ability to create the Elastic cluster, deploy the data nodes across zones in your Kubernetes cluster, and snapshot indexes to AWS S3. The operator was built and tested on a 1.7.X Kubernetes cluster and is the minimum version required due to the operators use of Custom Resource Definitions.

postgres-operator - Postgres operator creates and manages PostgreSQL clusters running in Kubernetes

•    Go

The operator watches additions, updates, and deletions of PostgreSQL cluster manifests and changes the running clusters accordingly. For example, when a user submits a new manifest, the operator fetches that manifest and spawns a new Postgres cluster along with all necessary entities such as Kubernetes StatefulSets and Postgres roles. See this Postgres cluster manifest for settings that a manifest may contain. The operator also watches updates to its own configuration and alters running Postgres clusters if necessary. For instance, if a pod docker image is changed, the operator carries out the rolling update. That is, the operator re-spawns one-by-one pods of each StatefulSet it manages with the new Docker image.

kooper - Kooper is a simple Go library to create Kubernetes operators and controllers.

•    Go

Kooper is a simple Go library to create Kubernetes operators and controllers. Kooper is a set of utilities packed as a library or framework to easily create Kubernetes controllers and operators.

aws-service-operator - AWS Service Operator allows you to create AWS resources using kubectl.

•    Go

The AWS Service Operator allows you to manage AWS resources using Kubernetes Custom Resource Definitions. Using the AWS Service Operator enables a gitops workflow to drive your infrastructure to the desired state leveraging Kubernetes Custom Resource Definitions (CRD), the Kubernetes internal control loop, and AWS cloudformation orchestration. Read more about "operators" here.

terraform-k8s - Terraform Cloud Operator for Kubernetes

•    Go

The Terraform Cloud Operator for Kubernetes provides first-class integration between Kubernetes and Terraform Cloud by extending the Kubernetes control plane to enable lifecycle management of cloud and on-prem infrastructure through Kubernetes manifests. Manifests can be deployed and managed using kubectl, Terraform, Gitops tools, or any other tool that allows you to manage Kubernetes custom resources. This operator provides a unified way to manage a Kubernetes application and its infrastructure dependencies through a single Kubernetes CustomResourceDefinition (CRD). After the infrastructure dependencies are created, pertinent information such as endpoints and credentials are returned from Terraform Cloud to Kubernetes.

console - Management UI for MinIO and MinIO operator

•    TypeScript

All console needs is a MinIO user with admin privileges and URL pointing to your MinIO deployment.

cass-operator - The DataStax Kubernetes Operator for Apache Cassandra

•    Go

Note that since the manifest will install a Custom Resource Definition, the user running the above command will need cluster-admin privileges.

postgres-operator-examples - Examples for deploying applications with PGO, the Postgres Operator from Crunchy Data

•    Smarty

This repository contains examples for deploying PGO, the Postgres Operator from Crunchy Data, using a variety of examples. The examples are grouped by various tools that can be used to deploy them.

kube-prometheus - Use Prometheus to monitor Kubernetes and application running on Kubernetes

This repository collects Kubernetes manifests, dashboards, and alerting rules combined with documentation and scripts to provide single-command deployments of end-to-end Kubernetes cluster monitoring.This repository has been merged with the Prometheus Operator. It can now be found under contrib/kube-prometheus.

007 - Small experimental language with a license to macro

•    Perl

Prague, Czech Republic. Around two o'clock at night. A single car pulls up to the section headquarters. Section chief JOHN DRYDEN gets out and looks around him before getting into the empty building.

dlpack - RFC for common in-memory tensor structure and operator interface for deep learning system

•    C

We do not intend to implement of Tensor and Ops, but instead use this as common bridge to reuse tensor and ops across frameworks.RFC proposals are opened as issues. The major release will happen as a vote issue to make sure the participants agree on the changes.

vim-operator-surround - Vim operator mapping to enclose text objects with surrounds like paren, quote and so on

•    Vim

This plugin provides Vim operator mappings to deal with surrounds like (), "" and so on. In addition, both end of the text object are the same character, vim-operator-surround recognizes them as a surround (this behavior is customizable with some variables). This plugin would be more useful with vim-textobj-between or vim-textobj-anyblock. And you can customize and add surround definitions in global and filetype specific scope.

rxify - An RxJS library wrapper that lets you execute Rx operators directly using marble-diagram ASCII string arguments

•    Javascript

An RxJS library wrapper that lets you execute Rx operators directly using marble-diagram ASCII string arguments. rxify was mainly created as an educational tool to guide those ramping up on Reactive Extensions for the first time by presenting an alternative way to visualize and experiment on its asynchronous features. However, some folks may find it useful for other purposes such as general problem-solving or simplifying unit tests.
