Kind: Error: failed to load image: exit status 1

[YiannisGkoufas]

What happened:

I try to load a custom image in the "multinode" kind cluster I just created and it fails.
See the following:

export KUBECONFIG="$(kind get kubeconfig-path --name="multinode")"
docker build -t my-custom-image:latest .
kind load --loglevel trace docker-image my-custom-image

And the output:

DEBU[16:44:19] Running: /usr/bin/docker [docker image inspect -f {{ .Id }} my-custom-image] 
DEBU[16:44:19] Running: /usr/bin/docker [docker ps -q -a --no-trunc --filter label=io.k8s.sigs.kind.cluster --format {{.Names}}\t{{.Label "io.k8s.sigs.kind.cluster"}}]

What you expected to happen:

The docker image to be successfully loaded in the cluster.

How to reproduce it (as minimally and precisely as possible):

Create the following file config.yaml

kind: Cluster
apiVersion: kind.sigs.k8s.io/v1alpha3
nodes:
- role: control-plane
- role: worker
- role: worker

Create the cluster:

kind create cluster --config config.yaml --name multinode

Try to load any image:

docker pull ubuntu
export KUBECONFIG="$(kind get kubeconfig-path --name="multinode")"
kind load --loglevel trace docker-image ubuntu

• kind version: (use kind version):
  v0.5.1

kind load --loglevel trace docker-image my-custom-image

should be:
kind load --loglevel trace docker-image --name=multinode my-custom-image

[BenTheElder]

--name keys your cluster, if you don't use the default cluster name then you need to specify it for any cluster operations.

[BenTheElder]

we should give a better error message here but we have broader tracking issues for that (and I'm working on that today, after bug triage etc... 😅 )

[YiannisGkoufas]

Ahhh apologies, didn't realize I had to specify the name when loading!
It works as expected with --name parameter
Maybe it should be mentioned in the documentation?

[BenTheElder]

I agree, we should update the image loading documentation :sweat_smile:
