Kubernetes Platform Toolkit

---

karina is an open-source toolkit for building platforms, which includes:

• Integrated Production Runtime for monitoring, logging, multi-tenancy, auth, policy, secrets, DBaaS and CICD.
  • Docker Registry (Harbor)
  • Authentication (Dex, Oauth Proxy)
  • Authorization & Policy Enforcement (Open Policy Agent and Gatekeeper)
  • Certificate Management (cert-manager)
  • Secret Management (Sealed Secrets, Vault)
  • CI/CD (Tekton, ArgoCD, Flux, kpack, keptn)
  • Database as a Service (postgres-operator, rabbitmq-operator, redis-operator)
  • Logging (ElasticSearch, Filebeat, Packetbeat, Auditbeat, Kibana)
  • Monitoring (Grafana, Prometheus, Thanos, Karma, Canary Checker)
  • Multi-Tenancy (Namespace Configurator Cluster Quotas, Kiosk)
• Cluster Provisioning framework for Kind, vSphere and Cluster API (Coming Soon)
• Operations focused CLI for health checks, backup and restore, rolling updates, logging, etc..

karina leverages a number of other standalone operators built by flanksource:

• kommons as high-level library wrapping client-go
• canary-checker for multi-cluster synthetic monitoring of pod scheduling, docker pulls, DNS, ICMP, LDAP, Postgres, HTTP, etc..
• template-operator for building re-usable CRD's similar to crossplane's XRD
• platform-operator for multi-tenancy support
• git-operator for deploying GitOps tools like Flux and exposing REST interfaces onto of Git.

Design Principles

• 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/S3 connection details, etc.
• Escape Hatches for when the defaults don't work for you, easily use kustomize patches to configure resource limits, labels, annotations and anything else on any object managed by karina.
• 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.
