Kubernetes Platform Toolkit

karina is a toolkit for building and operating kubernetes based, multi-cluster platforms. It includes the following high level functions:

Features

• Provision kubernetes clusters on vSphere (with NSX-T or Calico), Kind and Cluster API (Coming Soon)
• Deploy a production runtime for monitoring, logging, security, multi-tenancy, backups, storage, container registry and DBaaS
• Batteries Included - Most components require just a version to enable and are pre-configured with ingress, LDAP and TLS (managed by cert-manager) due to a shared infrastructure model that includes information such as top-level wild card domain, LDAP connection details, S3 connection details, etc.
• Escape Hatches for when the defaults don't work for you, easily use kustomize patches to configure resources limits, labels, annotations and arguments.
• Integrated, but independent - karina works best when used to provision a kubernetes cluster and then deploy and test a production runtime, but each function can also be used independently, i.e you can run karina e2e tests in an environment that wasn't provisioned or deployed by karina.
• De-Centralized multi-cluster authentication using a root CA for administrator-level offline authentication, and Dex for online user authentication. CLI Clients for
• CLI Addons/Wrappers to perform day 2 and incident mitigation tasks such as rolling updates, restarts, backup, restore, failover, replication, logging configuration, system dumps etc..

Getting Started

To get started provisioning see the quickstart's for Kind and vSphere

Production Runtime

• Docker Registry (Harbor)
• Certificate Management (cert-manager)
• Secret Management (Sealed Secrets, Vault)
• Monitoring (Grafana, Prometheus, Thanos, Karma, Canary Checker)
• Logging (ElasticSearch, Filebeat, Packetbeat, Auditbeat, Kibana)
• Authentication (Dex)
• Authorization & Policy Enforcement (Open Policy Agent)
• Multi-Tenancy (Namespace Configurator Cluster Quotas, Kiosk)
• Database as a Service (postgres-operator)

Comparisons

Production Runtime

A production runtime is the suite of tools that are added to a Kubernetes cluster to provide functionality such as Authentication, Logging and Monitoring
