skaffold: Skaffold sync failure

I am running skaffold 24 version. I am using skaffold sync(with sync command same as in version 26), its failing with exit status 2.

Expected behavior

I should be able to directly sync the modified file to running pod.

Actual behavior

Returning exit code 2.

level=warning msg=“Skipping deploy due to sync error: copying files: exit status 2”

Information

• Skaffold version: 24
• Operating system: Linux
• Contents of skaffold.yaml:

apiVersion: skaffold/v1beta6
kind: Config
build:
 artifacts:
 - image: someurl.com/kube/pythonserver
 context: .
 sync:
 '*.py': .
 kaniko:
 buildContext:
 localDir: {}
 namespace: prashant
 image: someurl.com/gkp/kaniko-executor:latest dockerConfig:
 path: C:\Users\prashant\.docker\config.json
deploy:
 kubectl:
 manifests:
 - deploy.yml

Steps to reproduce the behavior

1. Make a sample hello world python application
2. Create dockerfile for the same, build and deploy the application using kaniko and skaffold in dev mode.
3. Change Hello world to Hello New world in python application.
4. Skaffold would catch the changes made and would try to copy the file to running pod.
5. Skaffold fails to copy the changed file.

Here is the Dockerfile for my application

FROM someurl.net/lrh7:latest
RUN yum install tar -y
COPY app.py .
EXPOSE 8080
CMD [ "python", "app.py" ]
