Container Cloud Service Engine (CCSE) provides log center services. This section describes how to centrally report application service logs to the Cloud Log Service center for retrieval and query.

Before You Begin

You have activated Cloud Log Service.
You have activated CCSE, created a container cluster, and installed the log plug-in. For details, see Container Cloud Service Engine (CCSE) Documentation.

Configuring Log Collection When Releasing an App

As an example, the following describes how to configure log collection for a Tomcat

service application for reference.

Log in to the CCSE console.
Click on the name of the target cluster to enter the Cluster Management page.
In the Workload menu bar, select the Stateless and click the Add button.
Configure the workload name, data volume, scaling method, number of instances, and container information in the instance based on your actual needs. For details, see Container Cloud Service Engine (CCSE) Documentation.
Click Show Advanced Settings right below Instance Container to display the Pod Annotation section.
Enter the pod annotation information.
Annotation name: ctyun.sls.logs
Annotation value:

[ {"sls.capture.type":"stdout","sls.app.name":"tomcat","sls.container.name":"tomcat-demo","sls.log.project":"ccse_ccse-als-test","sls.log.rule":"ccse_ccse-als-test_default_deployment_tomcat","sls.log.unit":"ccse_ccse-als-test_default_deployment_tomcat" } ]

• Description of the annotation value:

Values such as sls.log.project sls.log.rule sls.log.rule need to be adjusted based on the cluster name.

sls.capture.type is the output type of Cloud Log Service, including the standard output (stdout) and file logs (applog). If it is a file log, you need to specify the log path using another annotation "key：sls.log.path". The annotation value in this example is the standard output (stdout).

The annotation value is in the form of a JSON array and supports log collection on multi-container instances.

Fill in the workload type as it is, and use lowercase letters for "statefulset deployment".

• Submit the application for release.

Viewing Logs on the CCSE Console

Click O&M Management on the left to enter the Log Center page and select the Cloud Log Service tab.
Select the namespace and workload name used to release the workload. If the log can be retrieved, the log function is normal.

Viewing Logs on the Cloud Log Service Console

Log in to the Cloud Log Service console.
Select the log project corresponding to the container cluster. When you install the plug-in in the container cluster, a log project named k8s-log-{clusterid} will be created by default.
Select the target log unit and click Retrieve Log to view the collected logs and you can retrieve and analyze logs.

Collection Configuration Rule Management

When you finish the log collection configuration in CCSE, you can view and manage the collection configuration on the Cloud Log Service console. Select the target log project and log unit, and you can view and manage the current collection rules under the Data Ingestion column.
