The text discusses the common challenges developers face when debugging build failures in CI/CD environments, particularly when lacking secure access to the necessary resources for real-time troubleshooting. It highlights a typical interaction where developers seek SSH access from SRE teams to debug issues, but face security constraints that prevent this, leading to inefficient debugging processes. The text then introduces CircleCI's SSH debugging feature as a solution, allowing developers to securely access execution environments and troubleshoot failed builds directly on the resources, thereby saving time and improving efficiency. By detailing a specific build failure scenario, the text explains how CircleCI's SSH feature enables users to identify and rectify issues related to missing environment variables, ultimately facilitating a smoother development process.
