KubeFire is to create and manage Kubernetes clusters running on FireCracker microVMs via weaveworks/ignite.
DNS and Service Discovery.
CoreDNS is a DNS server. It is written in Go. It can be used in a multitude of environments because of its flexibility.
CoreDNS is a DNS server/forwarder, written in Go, that chains plugins. Each plugin performs a (DNS) function.
CoreDNS can listen for DNS requests coming in over UDP/TCP (go'old DNS), TLS (RFC 7858), also called DoT, DNS over HTTP/2 - DoH - (RFC 8484) and gRPC (not a standard).
Production Grade k8s Installation, Upgrades and Management. The easiest way to get a production grade Kubernetes cluster up and running. We like to think of it as kubectl for clusters.
kops will not only help you create, destroy, upgrade and maintain production-grade, highly available, Kubernetes cluster, but it will also provision the necessary cloud infrastructure.
AWS (Amazon Web Services) and GCE (Google Cloud Platform) are currently officially supported, with DigitalOcean, Hetzner and OpenStack in beta support, and Azure in alpha.
Open source cost monitoring for cloud native environments.
OpenCost is a vendor-neutral open source project for measuring and allocating infrastructure and container costs in real time. Built by Kubernetes experts and supported by Kubernetes practitioners, OpenCost shines a light into the black box of Kubernetes spend.
Purpose-built OS for Kubernetes, fully managed by Kubernetes.
k3OS is a Linux distribution designed to remove as much OS maintenance as possible in a Kubernetes cluster. It is specifically designed to only have what is needed to run k3s. Additionally the OS is designed to be managed by kubectl once a cluster is bootstrapped. Nodes only need to join a cluster and then all aspects of the OS can be managed from Kubernetes. Both k3OS and k3s upgrades are handled by the k3OS operator.
kube-image-keeper (a.k.a. kuik) is a container image caching system designed for Kubernetes. It ensures the availability of your favorite container images by keeping a local copy within your k8s cluster.
Just-in-time Nodes for Any Kubernetes Cluster.
Karpenter simplifies Kubernetes infrastructure with the right nodes at the right time.
Karpenter automatically launches just the right compute resources to handle your cluster's applications. It is designed to let you take full advantage of the cloud with fast and simple compute provisioning for Kubernetes clusters.
Progressive Delivery Operator for Kubernetes.
Flagger is a progressive delivery tool that automates the release process for applications running on Kubernetes. It reduces the risk of introducing a new software version in production by gradually shifting traffic to the new version while measuring metrics and running conformance tests.
Open Interoperable HCI with Harvester.
Harvester is the next generation of hyperconverged infrastructure designed for the modern cloud-native environment. Completely open-source and free to use, Harvester easily integrates into Rancher helping operators consolidate workloads and reduce the complexity of their infrastructure.
Pluto is a utility to help users find deprecated Kubernetes apiVersions in their code repositories and their helm releases.
Automatically provision and manage TLS certificates in Kubernetes.
cert-manager adds certificates and certificate issuers as resource types in Kubernetes clusters, and simplifies the process of obtaining, renewing and using those certificates.
It supports issuing certificates from a variety of sources, including Let's Encrypt (ACME), HashiCorp Vault, and Venafi TPP / TLS Protect Cloud, as well as local in-cluster issuance.
cert-manager also ensures certificates remain valid and up to date, attempting to renew certificates at an appropriate time before expiry to reduce the risk of outages and remove toil.
Open Source Marketplace For Kubernetes.
arkade is how developers install the latest versions of their favourite tools and Kubernetes apps.
With arkade get, you'll have kubectl, kind, terraform, and jq on your machine faster than you can type apt-get install/brew update.
Deploy a Production Ready Kubernetes Cluster
The Most Widely Deployed Open Source Cloud Software in the World.
Deployed by thousands. Proven production at scale. OpenStack is a set of software components that provide common services for cloud infrastructure.
Pacemaker is an advanced, scalable high-availability cluster resource manager.
It supports "N-node" clusters with significant capabilities for managing resources and dependencies.
It will run scripts at initialization, when machines go up or down, when related resources fail and can be configured to periodically check resource health.
Kubescape is a K8s open-source tool providing a multi-cloud K8s single pane of glass, including risk analysis, security compliance, RBAC visualizer and image vulnerabilities scanning.
Kubescape scans K8s clusters, YAML files, and HELM charts, detecting misconfigurations according to multiple frameworks (such as the NSA-CISA, MITRE ATT&CK®), software vulnerabilities, and RBAC (role-based-access-control) violations at early stages of the CI/CD pipeline, calculates risk score instantly and shows risk trends over time.
The world's lightest, fastest service mesh. A different kind of service mesh.
Ultra light, ultra simple, ultra powerful. Linkerd adds security, observability, and reliability to Kubernetes, without the complexity. CNCF-hosted and 100% open source.
Cloud native certificate management. X.509 certificate management for Kubernetes and OpenShift.
cert-manager creates TLS certificates for workloads in your Kubernetes or OpenShift cluster and renews the certificates before they expire.
A community Linux distribution designed for container workloads, with high security and low maintenance.
Flatcar Container Linux is designed from the ground up for running container workloads. It fully embraces the container paradigm, including only what is required to run containers.
Update monitor & manager for applications using the Omaha protocol, optimized for Flatcar Container Linux.
Nebraska is an update manager for Flatcar Container Linux.
Nebraska offers an easy way to monitor and manage the rollout of updates to applications that use the Omaha protocol, with special functionality for Flatcar Container Linux updates.
