Let's say something like this is being returned.

failed quota: my-quota: must specify limits.cpu,limits.memory,requests.cpu,requests.memory

In this example, there is a quota or cluster resource quota named my-quota. The oc get quota command with the --all-namespaces flag and grep can be used to determine if my-quota is a quota in a certain project. Similarly, the oc get clusterresourcequota could be used to determine if my-quota is a cluster resource quota.

~]$ oc get quota --all-namespaces | grep my-quota
my-project    my-quota    8m27s   pods: 8/10, requests.cpu: 30m/1, requests.memory: 288Mi/1Gi          limits.cpu: 1500m/2, limits.memory: 384Mi/2Gi

Notice in this example that my-quota has quotas for.

• requests.cpu
• requests.memory
• limits.cpu
• limits.memory

In this scenario, check your deployment or deployment config YAML for the requests/limits cpu/memory. If your deployment or deployment config does not have these settings, updating your deployment or deployment config to have these setting will probably resolve this issue. Check out my article on updating your deployment or deployment config with CPU and Memory requests and limits.

Be aware that you may need to specify the resource CPU and Memory requests and limits under both strategy and containers in your YAML.

spec:
  strategy:
    resources:
      requests:
        cpu: 10m
        memory: 128Mi
      limits:
        cpu: 500m
        memory: 512Mi
  template:
    spec:
      containers:
      - name: hello-openshift
        image: openshift/hello-openshift:latest
        resources:
          requests:
            cpu: 10m
            memory: 128Mi
          limits:
            cpu: 500m
            memory: 512Mi

Or if you are using limits to set the min and max CPU and Memory for pods and containers in the project, ensure your limits has min and max CPU and memory for both pods and containers.
