How to fix 'map[] does not contain declared merge key: name' error when I edit and save the pod yaml?
I 'm trying to pull an image from a private registry. But the status of pod is 'ImagePullBackOff', which means I need to add a secret to the pod.
Events:
Type Reason Age From Message
---- ------ ---- ---- -------
Normal Pulling 52m (x255 over 22h) kubelet, cn-huhehaote.i-hp3fkfzlcf1u9cigq2h7 pulling image "xxx/fcp"
Normal BackOff 8m (x5597 over 22h) kubelet, cn-huhehaote.i-hp3fkfzlcf1u9cigq2h7 Back-off pulling image "xxx/fcp"
Warning Failed 3m (x5618 over 22h) kubelet, cn-huhehaote.i-hp3fkfzlcf1u9cigq2h7 Error: ImagePullBackOff
So I added the following code in pod yaml.
spec:
containers:
- name: private-reg-container
image: <your-private-image>
imagePullSecrets:
- name: my-secret
Then I got
error: map: map[] does not contain declared merge key: name
The solution I searched out is to delete 'imagePullSecret', which doesn't work for me. I wonder how to fix the error. Can anyone help me?
kubectl version is

I've stumbled with the same problem (using helm) and I've found out, that it is not allowed to edit the
imagePullSecretThe solution was to delete the deployment and recreate it.
Things may be different now in early 2023. I didn't have to delete the deployment (fortunately).
I had to delete the existing (empty) imagePullSecrets and then patch them. So:
# Delete existing imagePullSecret
kubectl patch deployment my-deploy \
--type=json \
-p='[{"op": "remove", "path": "/spec/template/spec/imagePullSecrets"}]'
# Now add the correct one
kubectl patch deployment my-deploy \
--patch '{"spec": {"template": {"spec": {"imagePullSecrets": [{"name": "my-registry-creds"}]}}}}'
As @fiunchinho mentioned in comments and as per Federation with Kubefed - cluster federation is deprecated.
Use of Federation v1 is strongly discouraged. Federation V1 never achieved GA status and is no longer under active development. Documentation is for historical purposes only.
The solution is to use Kubernetes Federation v2. For more details you can refer to Federation v2 user guide and Federation v development guide
Recently, I encountered the same issue in ArgoCD while deploying an
application.yaml
"Failed to compare desired state to live state: failed to calculate diff: map: map[] does not contain declared merge key: name"
![Failed to compare desired state to live state: failed to calculate diff: map: map[] does not contain declared merge key: name](https://i.sstatic.net/IpqwhtWk.png)
To resolve both issues, I accessed the ArgoCD web interface and navigated to the affected application and I selected the ConfigMap in the 'Unknown' state and delete it using the 'Foreground Delete' (option) since this ensures that all dependent resources are completely removed before completing the operation.
After ArgoCD detected the deletion of the ConfigMap and automatically recreated it, synchronizing the repository and updating the state of the resources.
The 'Unknown' state of the resources was correctly updated, and also the 'ComparisonError' disappeared, allowing ArgoCD to correctly compare the desired state with the actual state.
I got this error when I modified a deployment remove a certain segment of configuration.
I had accidentally removed a mandatory section of the deployment along with the part I actually wanted to remove, giving this error.
Carefully double check the part you are erasing from the yaml, to see whether you are accidentally removing unnecessary parts.
