Docker Container Creation Failed No Such Image public.ecr.aws SAM Build Python

What this error means

Container creation failed: No such image: public.ecr.aws/sam/build-python3.12:latest-x86_64 is a Docker failure pattern reported for developers trying to fix docker container creation failure when running sam build —use-container with missing ecr image on apple silicon. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

Stack Overflow user on M2 Pro with Docker v29.2.0 gets ‘No such image: public.ecr.aws/sam/build-python3.12:latest-x86_64’ when running sam build —use-container. ARM64 vs x86_64 architecture mismatch issue with AWS SAM CLI Docker images. Category is Docker (container runtime error).

Common causes

Quick fixes

1. Confirm the exact error signature matches Container creation failed: No such image: public.ecr.aws/sam/build-python3.12:latest-x86_64.
2. Check the Docker account, local tool state, and provider configuration involved in the failing workflow.
3. Compare the failing environment with a known working setup, then change one configuration value at a time.

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 Container creation failed: No such image: public.ecr.aws/sam/build-python3.12:latest-x86_64 text and the smallest action that reproduces it.

Can I ignore this error?

No. Treat it as a failed Docker 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 Container creation failed: No such image: public.ecr.aws/sam/build-python3.12:latest-x86_64.
