ASSISTANT
The error message:
```
error: daemonsets.apps "prometheus-prometheus-node-exporter" is invalid
A copy of your changes has been stored to "/tmp/kubectl-edit-1500215338.yaml"
error: Edit cancelled, no valid changes were saved.
```
indicates that the edits you made to the DaemonSet were syntactically invalid (YAML formatting or structure issues) and so Kubernetes rejected them.
---
## How to fix this edit error and correctly remove the affinity block
### Steps:
1. **Get the current DaemonSet YAML to a file**:
```bash
kubectl get ds prometheus-prometheus-node-exporter -n prometheus -o yaml > node-exporter-ds.yaml
```
2. **Open the file with your preferred editor (vim/nano/micro)**:
```bash
nano node-exporter-ds.yaml
```
3. **Find the `affinity:` block under `.spec.template.spec` and completely remove it**
For example, remove this section (including indentation):
```yaml
affinity:
nodeAffinity:
requiredDuringSchedulingIgnoredDuringExecution:
nodeSelectorTerms:
- matchExpressions:
- key: eks.amazonaws.com/compute-type
operator: NotIn
values:
- fargate
- key: type
operator: NotIn
values:
- virtual-kubelet
```
Make sure you remove exactly the whole `affinity` key and its children.
---
**Important:** Be careful **not** to remove or break any other required sections in the file (like `metadata`, `spec`, `containers`, etc.).
---
4. **Save the file**
5. **Apply the fixed YAML**
```bash
kubectl apply -f node-exporter-ds.yaml
```
6. **Check DaemonSet and Pods**
```bash
kubectl get ds prometheus-prometheus-node-exporter -n prometheus
kubectl get pods -n prometheus -l app.kubernetes.io/name=prometheus-node-exporter -w
```
Wait to see if pods start scheduling and become `Running`.
---
## If you prefer patching instead of editing full YAML:
You can delete the affinity with a strategic patch:
```bash
kubectl patch ds prometheus-prometheus-node-exporter -n prometheus --type=json -p='[{"op":"remove","path":"/spec/template/spec/affinity"}]'
```
This command **removes the affinity section** safely.
Then check pods:
```bash
kubectl get pods -n prometheus -l app.kubernetes.io/name=prometheus-node-exporter -w
```
---
## Notes:
- Always validate YAML syntax (e.g. online YAML linters) if editing manually.
- Make sure indentation matches properly, Kubernetes YAML is indentation sensitive.
