New Pod Check

Check Items

• Check whether pods can be created on the existing nodes after the cluster is upgraded.
• Check whether pods can be created on new nodes after the cluster is upgraded.

Procedure

After creating a node based on New Node Check, create a DaemonSet workload to create pods on each node.

1. Log in to the CCE console and click the cluster name to access the cluster console.
2. In the navigation pane, choose Workloads. On the displayed page, click Create Workload or Create from YAML in the upper right corner. For details about how to create a DaemonSet, see Creating a DaemonSet.

   It is a good practice to use the image for routine tests as the base image. You can deploy minimum pods for an application by referring to the following YAML file.

   

   In this test, YAML deploys DaemonSet in the default namespace, uses ngxin:perl as the base image, requests 10m vCPUs and 10 MiB memory, and limits 100 MB CPU and 50 MiB memory.

   apiVersion: apps/v1
   kind: DaemonSet
   metadata:
     name: post-upgrade-check
     namespace: default
   spec:
     selector:
       matchLabels:
         app: post-upgrade-check
         version: v1
     template:
       metadata:
         labels:
           app: post-upgrade-check
           version: v1
       spec:
         containers:
           - name: container-1
             image: nginx:perl
             imagePullPolicy: IfNotPresent
             resources:
               requests:
                 cpu: 10m
                 memory: 10Mi
               limits:
                 cpu: 100m
                 memory: 50Mi

3. After the workload is created, check whether the pods of the workload are running properly.
4. After the check is complete, choose Workloads in the navigation pane. On the displayed page, click the DaemonSets tab, locate the post-upgrade-check workload, and choose More > Delete in the Operation column to delete the test workload.

Solution

If the pod cannot be created or the pod status is abnormal, contact technical support and specify whether the exception occurs on new nodes or existing nodes.
