This topic describes how to view the status of an application in the Container Service
for Kubernetes (ACK) console after you migrate the application configurations. This
topic also describes how to troubleshoot and fix application startup issues when the
application configurations are migrated.
Check the application startup process
After you manually migrate application configurations or migrate application configurations
by using Kompose, you can check whether the application starts up as expected in the
ACK console. If any exceptions occur during the startup process, you can view application
boot log in the console to locate the causes.
- Log on to the ACK console.
- In the left-side navigation pane, click Clusters.
- On the Clusters page, find the cluster that you want to manage and click the name of the cluster
or click Details in the Actions column. The details page of the cluster appears.
- In the left-side navigation pane of the details page, choose .
- Select the corresponding namespace and click Details on the right side of the application that fails to start up.
- Click the Pods tab, find the container that runs the application and click Logs in the Actions column.
- In the Logs tab, view the log of the application.
Fix application startup issues
Analyze and fix application startup issues successively. For example, the preceding
log indicates that the nginx-deployment application fails to access config. To fix
this issue, perform the following operations:
- Manually create a Service in the ACK cluster to allow other applications to access
config.
The
Name in the following figure indicates the Service name. The name must be the same as
the hostname. You can specify
Port Mapping as needed. For example, you can specify the same value for
Name,
Service Port, and
Container Port. For more information, see
Manage Services in the ACK console.

- After you create the Service, deploy the application again to check whether the issue
is fixed.
If the state of the container is
Running as shown in the following figure, it indicates that the container starts up as expected.

Exceptions may occur during the application startup process. For more information
about these exceptions and how to fix them, see Troubleshooting.
