Architecture

Scaleway Serverless Jobs only supports amd64 architecture for images.

For example, if you build an image using an ARM CPU, such as Apple Silicon M series, your image will be in the arm64 architecture, and you will have an error message during deployment.

You must ensure that you build your image to target amd64 architecture, to acheive this there are multiple solutions:

You can use the following docker command: docker buildx build --platform linux/amd64 ., or
You can use an Instance with amd64 architecture to run your builds.
