Unable to run kubernetes pipeline


I’m trying to execute a simple kubernetes pipeline but when my pipeline failed immediately because kubernetes trying to spawn a pod to execute all my steps but this pod is immediately killed by kubernetes.

When I check the events I have the following weird outputs:

  Normal  Started    6s                kubelet, ip-10-64-7-249.eu-central-1.compute.internal  Started container
  Normal  Created    5s (x2 over 10s)  kubelet, ip-10-64-7-249.eu-central-1.compute.internal  Created container
  Normal  Killing    5s                kubelet, ip-10-64-7-249.eu-central-1.compute.internal  Killing container with id docker://drone-m5b4sok6jlj24kojgbfb:Container spec hash changed (3761618974 vs 538082423).. Container will be killed and recreated.

You can find my pipeline definition here:

kind: pipeline
type: kubernetes
name: test-first-pipeline

- name: example
  image: busybox
  - echo "hello world"
  - echo "it's working"

And my pipeline failed immediately at the built-in clone step. So my step example is never executed.

Does drone patch something on the pod which cause this inconsistency ?
Please can someone help me with that issue ?
