NoneType' object is not subscriptable error during aws-eks-kubectl-run pipe run




I'm trying to apply a yaml file using the aws-eks-kubectl-run pipe but it returns an error.

If I try to apply the yaml file manually it works without any issues

The error is:

✔ Successfully updated the kube config.
Traceback (most recent call last):
File "/", line 42, in <module>
File "/usr/local/lib/python3.7/site-packages/kubectl_run/", line 112, in run
File "/usr/local/lib/python3.7/site-packages/kubectl_run/", line 77, in handle_apply
self.update_labels_in_metadata(template_file, labels)
File "/usr/local/lib/python3.7/site-packages/kubectl_run/", line 31, in update_labels_in_metadata
yaml_doc['metadata'].setdefault('labels', {}).update(labels)
TypeError: 'NoneType' object is not subscriptable

I'm trying to apply the file

- wget
- ls -latrh
- pipe: atlassian/aws-eks-kubectl-run:1.2.4
CLUSTER_NAME: "$name-$environment"
# KUBECTL_ARGS: '<array>' # Optional
RESOURCE_PATH: "spotinst-kubernetes-cluster-controller-ga.yaml"
# LABELS: '<array>' # Optional
DEBUG: 'true'


Changing the 'with_default_labels' to true also doesn't fix the issue.


Any idea how to fix this issue? for other yaml files it works without any issues

Hi @Rutger van Bruggen ,

thank you for your question.

The problem is in "spotinst-kubernetes-cluster-controller-ga.yam" file. It ends with three dashes (---).

According to YAML specs 2.2 Structures:

YAML uses three dashes (---) to separate directives from document content. This also serves to signal the start of a document if no directives are present. Three dots ( ...) indicate the end of a document without starting a new one, for use in communication channels.

during parsing the file pipe's method `update_labels_in_metadata` tries to find all separate documents from provided file, but the latest three dashes (---) declare false start of the new document.

It'd be better add pre-processing and remove trailing three dashes (---) from the file.

- truncate -s-4 spotinst-kubernetes-cluster-controller-ga.yaml

Also, we'll think about this case to prevent breaking the pipe.

Thanks for the update. I can confirm it fixed the issue
