Hi @ancient-wolf-19325 can u help me fix that issue?

The error

ERROR: name unknown: repository name not known to registry

during the

docker build --push

step means Docker is trying to push the image to a registry (

cr.flyte.org/flyteorg/flyte-sandbox-bundled

) that does not exist or is not accessible from your environment. This is common when using Flyte's local sandbox or demo setup, which does not have a remote registry at that address. To fix this for local development, you should configure your Flyte project to use a local registry (like

localhost:30000

) or avoid the

--push

step by using the default image that comes with the sandbox, or by building and tagging images locally without pushing to a remote registry. For more details, see Flyte local setup instructions and ImageSpec registry setup. Would you like step-by-step instructions on how to configure your registry for local development or how to use a local image with Flyte?
