ALM-12 Failed to Update Process Application

ALM-12 Failed to Update Process Application


This alarm is reported when the configuration of a pod fails to be updated.

Pod: In Kubernetes, pods are the smallest unit of creation, scheduling, and deployment. A pod is a group of relatively tightly coupled containers. Pods are always co-located and run in a shared application context. Containers within a pod share a namespace, IP address, port space, and volume.

System Actions

The pod keeps restarting.

Possible Causes

The configuration update lifecycle configured for the application is incorrect.


  1. Obtain the name of the pod whose configuration fails to be updated.

    1. Use a browser to log in to the FusionStage OM zone console.
      1. Log in to ManageOne Maintenance Portal.
        • Login address: https://Address for accessing the homepage of ManageOne Maintenance Portal:31943, for example,
        • The default username is admin, and the default password is Huawei12#$.
      2. On the O&M Maps page, click the FusionStage link under Quick Links to go to the FusionStage OM zone console.
    2. Choose Application Operations > Application Operations from the main menu.
    3. In the navigation pane on the left, choose Alarm Center > Alarm List and query the alarm by setting query criteria.
    4. Click to expand the alarm information. Record the values of name and namespace in Location Info, that is, podname and namespace.

  2. Use PuTTY to log in to the manage_lb1_ip node.

    The default username is paas, and the default password is QAZ2wsx@123!.

  3. Run the following command and enter the password of the root user to switch to the root user:

    su - root

    Default password: QAZ2wsx@123!

  4. Run the following command to obtain the IP address of the node on which the pod runs:

    kubectl get pod podname -n namespace -oyaml | grep -i hostip:

    In the preceding command, podname is the instance name obtained in 1, and namespace is the namespace obtained in 1.

    Log in to the node using SSH.

  5. Search for the error information based on the pod name and correct the application configuration.

    1. Run the following commands to view the kubelet log:

      cd /var/paas/sys/log/kubernetes/

      vi kubelet.log

      Press the / key, enter the name of the pod, and then press Enter for search. If Failed or Error is displayed in the command output or if the log line starts with E, the error information may be displayed as shown in the following figure.

    2. Correct the lifecycle script based on the error information. If the following information is displayed, the configuration update lifecycle fails to be executed. In this case, you need to correct the application configuration, delete and deploy the application again, and then check whether the alarm is cleared.
      hostname:~ # cd /var/paas/sys/log/kubernetes/
      hostname:/var/paas/sys/log/kubernetes # vi kubelet.log
