It could be difficult to find a Scaleway image ID for the right zone, architecture, and instance type. The Scaleway marketplace API has an endpoint dedicated to that but it could be difficult to understand the response and to find the right image UUID.
Here is a bash command that returns a JSON with just the necessary information needed to find your image ID.
curl -s 'https://api-marketplace.scaleway.com/images?page=1&per_page=100' | sed 's/par1/fr-par-1/g; s/ams1/nl-ams-1/g' | jq '.images | map({"key": .label | gsub("_";"-"), "value": .versions[0].local_images}) | from_entries'
