builder: return error if a node fails to boot by crazy-max · Pull Request #3062 · docker/buildx (original) (raw)
I think this was intentional to make it so that if you have a multi-node builder and one of the nodes (temporarily) goes down then you can still build with rest of the builders. Eg. you could even have multiple nodes with the same arch for some redundancy.
I think it would be ok if inspect --bootstrap
fails but I think then it would need some more specific condition as this Boot()
function is also used in other cases.
