Deployment Details and Phase Logs

Inspect deployment phases, live logs, and failure details for a single rollout.

This guide covers deployment phase logs and the workflow for finding rollout errors.

About Deployment Phase Logs

Deployment details divide a rollout into ordered phases. Each phase shows progress and streams related Amazon Web Services (AWS) logs when logs are available.

The phase list can include trigger, build, infrastructure stack, bootstrap, before rollout, and after rollout phases. The exact phase content depends on the deployment.

Real-Time Log Tailing

When a deployment is active, the control plane polls AWS CloudWatch Logs and appends new events about every 20 seconds. If logs are not available yet, the viewer shows a waiting message.

Use the phase status indicators to find the first failed phase before you inspect log output.

Troubleshooting a Rollout

To locate a failed deployment phase and inspect the log output explaining why a deployment failed, you can use the deployment details view.

Before you start

The project must have at least one failed deployment.

Steps

1. Click Projects in the global sidebar.
2. Click your target project.
3. Click Deployments in the project sidebar.
4. Locate the failed deployment in the list.
5. Click the failed deployment row to open its details.
6. Scroll to Phases.
7. Click the failed phase accordion to expand it.
8. Review the log output for error messages.

What happens next

The page displays the failed phase logs so you can diagnose build, configuration, or infrastructure problems.
