Kubernetes(EKS) node groups
Kubernetes(EKS) provides node groups, which is used for provisioning and providing lifecycle management of nodes.
SpaceONE recommends using two seperate node groups, one for core service and the other for plugins.
| node group | Description |
|---|---|
| spaceone-core-nodegroup | Deploy core pods like identity, console, inventory |
| spaceone-supervisor-nodegroup | Deploy supervisor pods and plugins |
Each node group has its own kubernetes labels
| Key | Value |
|---|---|
| Category | core |
| Key | Value |
|---|---|
| Category | supervisor |
Helm chart value
Based on kubernetes labels on node groups, SpaceONE helm chart supports node selector options.
SpaceONE helm chart also supports ***pod.spec*** options, so that you can specific options for some pod.
One example is nodeSelector, which determines pod's location based on labels.
spaceone-core-nodegroup
Include nodeSelector at every chart value like below.
The value of nodeSelector is the key and value of label that you have applied above.
config:
enabled: true
replicas: 4
image:
name: public.ecr.aws/megazone/spaceone/config
version: 1.8.5
pod:
spec:
nodeSelector:
Category: core
spaceone-supervisor-nodegroup
Include nodeSelector at supervisor chart value like below.
In a supervisor value, you have to update two sections.
- KubernetesConnector
- pod
KubernetesConnector indicates that plugins created by supervisor has nodeSelector configuration.

Category: supervisor
pod indicates that supervisor pod itself is deployed with nodeSelector option.
