These improvements are designed to boost productivity and minimize downtime, making it easier than ever to ensure your CI/CD workflows are running smoothly.
Understanding the Debugging Interface¶
The debugging interface revolves around two key components: the pipeline view and the action details side panel.
Pipeline View¶
The pipeline view provides a clear, visual representation of each stage in your pipeline. You can see:
- The current status of each action.
- A history of action executions, including their start and end times.
- Color-coded indicators to quickly show whether an action is in progress, succeeded, or failed.
Action Details Side Panel¶
When you click on an action in the pipeline view, the action details side panel appears, offering:
- Comprehensive execution logs that detail the outputs of the action.
- The ability to re-trigger failed actions directly from this interface.
- A simple error message display that highlights what went wrong and proposes potential solutions.
This layout is intuitive, reducing the cognitive load on users and speeding up the debugging process.
Key Features of the New Debugging Experience¶
Here are some of the standout features of the new AWS CodePipeline debugging interface:
1. Simplified Access¶
