Introduction to Pluggable Components

Edit

Introduction

KubeSphere has decoupled some core feature components since v2.1.0. These components are designed to be pluggable which means you can enable them either before or after installation. By default, KubeSphere will be started with a minimal installation if you do not enable them.

Enable Pluggable Components

KubeSphere has six pluggable components as the following listed. You can enable any of them according to your demands. It is highly recommended that you install these pluggable components to discover the full-stack features and capabilities provided by KubeSphere. Please ensure your machines have sufficient CPU and memory before enabling them.

Pluggable Components

Pluggable Components Configuration Table

Attention: For multi-node installation, there should be at least ONE node having more than 8G of available memory, which is used for dependencies cache in CI node.

The following table shows the name, description and rough CPU/memory requirements of each component.

Component Feature CPU Memory
openpitrix-system Application Store 0.3 core 300 MiB
kubesphere-alerting-system alerting and notification system 0.08 core 80 M
kubesphere-devops-system（All-in-one） DevOps System 34 m 2.69 G
kubesphere-devops-system（Multi-node） DevOps System 0.47 core 8.6 G
istio-system Istio-based Service Mesh System 2 core 3.6 G
kubesphere-logging-system logging system 56 m 2.76 G
metrics-server enable HPA and "kubectl top" 5 m 44.35 MiB
GitLab + Harbor Source code repository & Image registry (3rd party App) 0.58 core 3.57 G
