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.

aws-iam-authenticator - A tool to use AWS IAM credentials to authenticate to a Kubernetes cluster

•    Go

A tool to use AWS IAM credentials to authenticate to a Kubernetes cluster. The initial work on this tool was driven by Heptio. The project recieves contributions from multiple community engineers and is currently maintained by Heptio and Amazon EKS OSS Engineers. If you are an administrator running a Kubernetes cluster on AWS, you already need to manage AWS IAM credentials to provision and update the cluster. By using AWS IAM Authenticator for Kubernetes, you avoid having to manage a separate credential for Kubernetes access. AWS IAM also provides a number of nice properties such as an out of band audit trail (via CloudTrail) and 2FA/MFA enforcement.

flagger - Istio and App Mesh progressive delivery Kubernetes operator

•    Go

Flagger is a Kubernetes operator that automates the promotion of canary deployments using Istio or App Mesh routing for traffic shifting and Prometheus metrics for canary analysis. The canary analysis can be extended with webhooks for running acceptance tests, load tests or any other custom validation. Flagger implements a control loop that gradually shifts traffic to the canary while measuring key performance indicators like HTTP requests success rate, requests average duration and pods health. Based on analysis of the KPIs a canary is promoted or aborted, and the analysis result is published to Slack.

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.

gardener - Kubernetes API server extension and controller manager managing the full lifecycle of conformant Kubernetes clusters (Shoots) as a service on AWS, Azure, GCP, and OpenStack

•    Go

The Gardener implements the automated management and operation of Kubernetes clusters as a service and aims to support that service on multiple Cloud providers (AWS, GCP, Azure, OpenStack). Its main principle is to use Kubernetes itself as base for its tasks. In essence, the Gardener is an extension API server along with a bundle of Kubernetes controllers which introduces new API objects in an existing Kubernetes cluster (which is called Garden cluster) in order to use them for the management of further Kubernetes clusters (which are called Shoot clusters). To do that reliably and to offer a certain quality of service, it requires to control the main components of a Kubernetes cluster (etcd, API server, controller manager, scheduler). These so-called control plane components are hosted in Kubernetes clusters themselves (which are called Seed clusters).

eksctl - a CLI for Amazon EKS

•    Go

eksctl is a simple CLI tool for creating clusters on EKS - Amazon's new managed Kubernetes service for EC2. It is written in Go, and uses CloudFormation. You will need to have AWS API credentials configured. What works for AWS CLI or any other tools (kops, Terraform etc), should be sufficient. You can use ~/.aws/credentials file or environment variables. For more information read AWS documentation.

kube2iam - kube2iam provides different AWS IAM roles for pods running on Kubernetes

•    Go

Provide IAM credentials to containers running inside a kubernetes cluster based on annotations.Traditionally in AWS, service level isolation is done using IAM roles. IAM roles are attributed through instance profiles and are accessible by services through the transparent usage by the aws-sdk of the ec2 metadata API. When using the aws-sdk, a call is made to the ec2 metadata API which provides temporary credentials that are then used to make calls to the AWS service.

aws-workshop-for-kubernetes - AWS Workshop for Kubernetes

•    Shell

This is a self-paced workshop designed for Development and Operations teams who would like to leverage Kubernetes on Amazon Web Services (AWS). This workshop provides instructions to create, manage, and scale a Kubernetes cluster on AWS, as well as how to deploy applications, scale them, run stateless and stateful containers, perform service discovery between different microservices, and other similar concepts.

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

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.

•    Smarty

kube-apiserver: exposes the Kubernetes API. It is the front-end for the Kubernetes control plane. It is designed to scale horizontally – that is, it scales by deploying more instances. etcd: is used as Kubernetes’ backing store. All cluster data is stored here. Always have a backup plan for etcd’s data for your Kubernetes cluster. kube-scheduler: watches newly created pods that have no node assigned, and selects a node for them to run on. kube-controller-manager: runs controllers, which are the background threads that handle routine tasks in the cluster. Logically, each controller is a separate process, but to reduce complexity, they are all compiled into a single binary and run in a single process. kubelet: is the primary node agent. It watches for pods that have been assigned to its node (either by apiserver or via local configuration file) kube-proxy: enables the Kubernetes service abstraction by maintaining network rules on the host and performing connection forwarding. keepalived cluster config a virtual IP address (192.168.20.10), this virtual IP address point to k8s-master01, k8s-master02, k8s-master03. nginx service as the load balancer of k8s-master01, k8s-master02, k8s-master03's apiserver. The other nodes kubernetes services connect the keepalived virtual ip address (192.168.20.10) and nginx exposed port (16443) to communicate with the master cluster's apiservers.
