facing docker buildx error when building for multiple platforms.

[prembhaskal]

What steps did you take:
I was trying to build kapp-controller locally for multiple platforms by following steps from here

I gave below value for platform

dev:
  ... snip ...
  #@schema/desc "Comma separated list of supported architectures"
  platform: "linux/amd64,linux/arm64"

and ran command bash ./hack/deploy.sh

What happened:
I got below error from kbld

fatal: No names found, cannot describe anything.
kapp-controller | starting build (using Docker buildx): . -> ghcr.io/prembhaskal/kapp-controller-test:rand-1699340468455821000-5915218025059-kapp-controller
kapp-controller | ERROR: Multiple platforms feature is currently not supported for docker driver. Please switch to a different driver (eg. "docker buildx create --use")
kapp-controller | error: exit status 1
kapp-controller | finished build (using Docker buildx)

What did you expect:
I expected that kbld creates docker image with multiple manifest, one each for the given platform.

Anything else you would like to add:
Below are

Environment:

• kbld version (use kbld --version):

% kbld --version
kbld version 0.38.0

• Docker registry used (e.g. Docker HUB):
  ghcr.io/prembhaskal/kapp-controller-test
• OS (e.g. from /etc/os-release):
  MAC M2 , macOS Ventura 13.6

docker buildx version

 % docker buildx version

If building images using buildkit:

• Buildkit version (e.g. kubectl buildkit version):
• Kubernetes version (e.g. kubectl version):

If building images using pack

• Pack Version (e.g. pack version):

https://docs.docker.com/engine/reference/commandline/buildx_create/#platform I think we should create a builder instance for multiple platforms, then do build.

[prembhaskal]

If this is found to be valid after triage, I would like to work on it.

[prembhaskal]

Found workaround today. The issue can be fixed by creating a builder instance before doing the build.

docker buildx create --name kc-build  
docker buildx use kc-build
bash ./hack/deploy.sh

 docker buildx inspect --bootstrap

@prembhaskal As you have mentioned (and the hint in the main issue also hints towards), we need to create a build instance to fix this. However, there's another related issue that we need to fix (details in slack thread). We can either update this issue or close and reopen another one for this.

[prembhaskal]

@praveenrewar yes I think it is similar to the slack discussion, but I didn't see any issue link there.

[praveenrewar]

Yeah, we don't have an issue created for the slack discussion, I was saying we could open another one.

[prembhaskal]

I think we can close this and reopen another one with other context added too.

[praveenrewar]

@joaopapereira has created #451, closing this one.
