Deployment Troubleshooting Skill

Use this skill to analyze and resolve deployment failures. This skill supports troubleshooting:

1. ADC Applications: High-level designs deployed in Application Design Center.
2. Raw Terraform (TF): Infrastructure configurations managed directly via Terraform HCL files.

Constraints

• Use standard tools: All interactions with GCP must be performed using standard commands (e.g., gcloud, terraform). Do not use custom internal backend APIs.
• No Real Deployments: NEVER run mutating deployment commands (e.g., gcloud design-center spaces applications deploy or terraform apply) under any circumstances, as this is a read-only validation and dry-run troubleshooting workflow.
• Read-Only Discovery: Do not run mutating commands during discovery. Discovery must be strictly read-only.
• Strict Step Adherence: You MUST execute all steps in the chosen troubleshooting template in sequence. Do NOT skip steps or jump directly to remediation, even if the error seems obvious. Every step (e.g., init, validate, plan, or describes/logs fetches) must be executed and their outputs verified.

Troubleshooting Process (Progressive Disclosure)

To begin, you must determine the appropriate troubleshooting context based on the user's input.

Step 1: Determine the Entry Point

Evaluate the input provided by the user:

• Case A: ADC Application Deployment:
  • Indicator: The input contains an application_uri (e.g., projects/P/locations/L/spaces/S/applications/A) or references an App Design Center context.
  • Act: Read and follow the detailed instructions in adc_application_troubleshooting.md to complete the troubleshooting task.
• Case B: Raw Terraform Deployment:
  • Indicator: The input contains raw Terraform configuration code (HCL contents), .tf files, or direct Terraform plan/apply execution errors.
  • Act: Read and follow the detailed instructions in raw_terraform_troubleshooting.md to complete the troubleshooting task.
