docs: Fix nonexistent python image tag in sandbox quickstart (DOCS-3127) - #3138
Merged
Conversation
The container_image example used python:3.15, which has no released tag on Docker Hub. Copying the snippet made the sandbox fail to start with an opaque SandboxFailedError. Use python:3.14 and note the failure mode. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Fixes DOCS-3127.
The
container_imageexample on Create sandboxes usedpython:3.15, which has no released tag on Docker Hub (only a release candidate). Copying the snippet as written makes the image pull fail (ImagePullBackOff), and the client surfaces onlySandboxFailedError: Sandbox <id> failed to start.python:3.14.SandboxFailedError.Localized copies under
fr/,ja/, andko/still carrypython:3.15; perAGENTS.md, they're left to the translation process.The opaque client error is tracked separately in coreweave/cwsandbox-client#106.
