Namespaces

Default Namespaces​

  • kube-system (Don't delete these by mistake)
  • default
  • kube-public (things available for every user)

Template​

apiVersion: v1
kind: Namespace
metadata:
  name: dev
---
tip

When accessing services within your own namespace, simply use the service name http://{svcName}.

When accessing services from a different namespace, use the fully qualified name:

http://{{svcName}}.{{namespace}}.svc.cluster.local

Limit resources within a Namespace​

apiVersion: v1
kinda: ResourceQuota
metadata:
  name: ${RESOURCE_NAME}
  # namespace: default
spec:
  hard:
    pods: "10" # Must be a string
    requests.cpu: "4"
    requests.memory: 5Gi
    limits.cpu: "10"
    limits.memory: 10Gi

  • Each Namespace can have its own policies and quotas
