Multi-Tenant Kubernetes Clusters: Challenges and Useful Tooling

• rbac-manager

  4 1,403 6.0 Go

  A Kubernetes operator that simplifies the management of Role Bindings and Service Accounts.

  

While RBAC is not particularly the toughest aspect of multi-tenancy, there are tools to help you with it. RBAC Manager was developed by Fairwinds to make security just a bit easier.

• dex

  37 9,025 9.4 Go

  OpenID Connect (OIDC) identity and OAuth 2.0 provider with pluggable connectors

  

Fortunately, there's an open-source tool called Dex that can help you with that. Dex uses OpenID Connect to drive authentication for other apps. This allows you to lean back and take comfort in the knowledge that your tenants can authenticate with their existing provider.

• InfluxDB

• vcluster

  70 5,577 9.7 Go

  vCluster - Create fully functional virtual Kubernetes clusters - Each vcluster runs inside a namespace of the underlying k8s cluster. It's cheaper than creating separate full-blown clusters and it offers better multi-tenancy and isolation than regular namespaces.

  

To get rid of these limitations, you can look into using vcluster. A vcluster is essentially an entire Kubernetes cluster, running inside of a regular namespace on the host cluster, giving you all the advantages of multi-tenancy, with close to none of the cons.

• prometheus

  381 52,748 9.9 Go

  The Prometheus monitoring system and time series database.

  

Thankfully, there are many tools that can ensure you have a complete overview of what's happening inside your cluster. Undoubtedly the most popular choice is Prometheus, and Prometheus in combination with Grafana can give you incredibly valuable insights.

• Grafana

  379 60,279 10.0 TypeScript

  The open and composable observability and data visualization platform. Visualize metrics, logs, and traces from multiple sources like Prometheus, Loki, Elasticsearch, InfluxDB, Postgres and many more.
