2. In the confirmation dialog box, click Terminate Deployment.

View container cluster information

1. On the Application Deployment page, click the target instance card. In the Application Deployment Instance panel, click Container Cluster.

2. In the Container Cluster dialog box, you can click the links to the right of View BizWorks-managed cluster information and Access workloads deployed on the cluster to view related container cluster information.

   • Click the link next to View BizWorks-managed Cluster Information to view basic information about the managed cluster on the Cluster Management page. You can click View Managed Cluster Details to view cluster details.

   • Click the link next to Access Workloads Deployed on the Cluster to view the related workload details in the Container Service for Kubernetes (ACK) console.

3. When you are finished, click Close.

View deployment records and logs

1. On the Application Deployment page, click a target instance card. In the Application Deployment Instance panel, you can view the deployment records in the Deployment Record area. The deployment records are displayed in a list and include information such as ID, Type, Status, Operator, and Completion Time. Each record provides links to its Details and Logs.

2. Click Logs to the right of the target deployment record ID to view the detailed pipeline logs for this deployment process.

   Note

   You can view logs only for Update and Create deployments.

   The logs are displayed as follows:

   • If you selected the default pipeline for Deployment Pipeline, the deployment logs are displayed in the Instance Change Records dialog box, showing the execution progress of each pipeline stage and detailed build and deployment logs.

   • If you selected a third-party pipeline for Deployment Pipeline, the deployment logs appear in the Deployment Logs dialog box. This dialog box shows pipeline information, the instance ID, and the running status, followed by detailed build and deployment logs.

     You can click View more run records to view more records on the pipeline instance page.

   • If a custom pipeline was selected for Deployment Pipeline, the deployment logs appear as follows.

     This example uses a pipeline with an added Pipeline Control task to illustrate the deployment logs for a custom pipeline.

     In the Instance Change Record dialog box, the pipeline displays five stages in sequence: Code Checkout, Maven, Create Image, Pipeline Control, and Deploy. A green checkmark next to each stage indicates it is complete. When the Deploy to Target Environment node is selected in the left-side pane, the right-side log area shows the Docker image push logs and application deployment status, ultimately displaying "Check deployment status [Deployment Successful]".

     • The deployment log details for a process in an approval workflow are as follows. In the Instance Change Record panel, the pipeline progress shows the execution status of each stage: Code Checkout, Maven, Create Image, Pipeline Control, and Deploy. The current Pipeline Control stage is shown as Pending for Approval.

       Click View Progress to see the specific approval progress. The approval process details page displays the process instance ID, creation time, creator, and running status, which is currently In Progress. The business information section shows the associated central application, and you can click the View link for more details. The approval progress is presented as a timeline: the Start Node has been completed by the initiator, and the process is currently at the Manual Approval node, which requires all designated approvers to pass (countersign). It shows that two people are pending approval. The Approve and Reject buttons are available at the bottom of the page for approvers.

       Alternatively, in the Deployment Records section of the instance details panel, click Details next to the target deployment record. In the Deployment Record Details panel, click Approval Progress to go to the approval progress details page. You can also find the target deployment record in the list and click Details to view its detailed information. The deployment record details include fields such as Operation Type, Status, Deployer, Completion Time, Deployment Environment, Deployment Content, Deployment Pipeline, and Deployment Policy. The Approval Progress button next to the status bar is the entry point for viewing the progress.

     • To terminate the deployment process of a custom pipeline, click Terminate Process in the Instance Change Record dialog box. In the confirmation dialog box, click OK. The deployment log details page shows the pipeline stage bar (including Code Checkout, Maven, Create Image, Pipeline Control, and Deploy), with status icons indicating whether each stage is completed, in progress, or not started. You can select a specific build step on the left to view its corresponding log output on the right. The Terminate Process button in the upper-right corner allows you to stop the current pipeline execution at any time.

3. Optional: View the detailed deployment configurations for a specific deployment record.

   1. Click Details to the right of the target deployment record ID.

   2. In the Deployment Record Details panel, you can view information such as Deployment Environment, Deployment Content, Resource Specifications, and Deployment Policy.
