GCP Cloud Run Deployment Fails — IAM Permission Denied for Service Account

What this error means

getting a IAM permission denied for running the application with service account which has roles/run.admin role set is a GCP failure pattern reported for developers trying to fix gcp cloud run terraform deployment failing because the service account with run.admin role still gets iam permission denied, needing additional roles or configuration. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

DDG snippet shows real Terraform-based GCP Cloud Run deployment failure. Service account explicitly has roles/run.admin but deployment is blocked by IAM permission denied. Related results show default App Engine service account also has this issue. Affects paid GCP cloud deployments.

Common causes

• DDG snippet shows real Terraform-based GCP Cloud Run deployment failure. Service account explicitly has roles/run.admin but deployment is blocked by IAM permission denied. Related results show default App Engine service account also has this issue. Affects paid GCP cloud deployments.

Quick fixes

1. Confirm the exact error signature matches getting a IAM permission denied for running the application with service account which has roles/run.admin role set.
2. Check the GCP account, local tool state, and provider configuration involved in the failing workflow.
3. Check the build output, project root, and deployment platform configuration before redeploying.

Platform/tool-specific checks

• Verify the command, editor, extension, or API client that produced the error.
• Compare local settings with CI, deployment, or editor-level settings when the error appears in only one environment.
• Avoid deleting credentials, local model data, or project settings until the failing scope is clear.

Step-by-step troubleshooting

1. Capture the exact error message and the command, editor action, or request that triggered it.
2. Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
3. Review the source evidence below and compare it with your environment.
4. Apply one change at a time and rerun the smallest failing action.
5. Keep the working fix documented for the team or deployment environment.

How to prevent it

• Keep provider/tool configuration documented.
• Record non-secret diagnostics such as tool version, provider name, model name, and command path.
• Add a lightweight check before CI or production workflows depend on the tool.

FAQ

What should I check first?

Start with the exact getting a IAM permission denied for running the application with service account which has roles/run.admin role set text and the smallest action that reproduces it.

Can I ignore this error?

No. Treat it as a failed GCP workflow until the root cause is understood.

Is this guaranteed to have one fix?

No. The imported evidence supports the troubleshooting path above, but tool behavior can vary by account, plan, version, provider, and local configuration.

How do I know the fix worked?

Rerun the same command, editor action, or request. The fix is working when that action completes without getting a IAM permission denied for running the application with service account which has roles/run.admin role set.
