Mastering Kubernetes

Creating quotas

1. Create a compute quota object:

    apiVersion: v1
    kind: ResourceQuota
    metadata:
      name: compute-quota
    spec:
      hard:
        pods: "2"
        requests.cpu: "1"
        requests.memory: 20Mi
        limits.cpu: "2"
        limits.memory: 2Gi
    
    > kubectl create -f compute-quota.yaml
    resourcequota "compute-quota" created

2. Next, let's add a count quota object:

    apiVersion: v1
    kind: ResourceQuota
    metadata:
      name: object-counts-quota
    spec:
      hard:
        configmaps: "10"
        persistentvolumeclaims: "4"
        replicationcontrollers: "20"
        secrets: "10"
        services: "10"
        services.loadbalancers: "2"
    
    > kubectl create -f object-count-quota.yaml
    resourcequota "object-counts-quota" created 

3. We can observe all the quotas:

    > kubectl get quota
    NAME                     AGE
    compute-resources        17m
    object-counts 15m ...
