Pod Kubernetes ki bloke nan `Pending` — kisa sa vle di?

Question

Mwen deplwaye yon app e pod la rete `Pending` pandan plizyè minit. Li pa janm vin `Running`. Kijan pou m konnen poukisa?

Accepted Answer

`Pending` vle di Kubernetes **pa jwenn yon nœud pou mete pod la** (oswa li poko ka kreye l). Premye bagay pou fè:

```bash
kubectl describe pod <non-pod>
```

Gade seksyon **Events** anba a. Kòz ki pi komen yo:

1. **`Insufficient cpu` / `Insufficient memory`**: `requests` pod la twò wo pou nœud ki disponib yo. Bese `resources.requests` oswa ajoute nœud.
2. **`pod has unbound immediate PersistentVolumeClaims`**: volim nan poko kreye. Verifye `kubectl get pvc` ak `storageClassName`.
3. **`node(s) had untolerated taint`**: nœud yo gen *taint* e pod la pa gen *toleration* ki koresponn.
4. **`didn't match Pod's node affinity/selector`**: `nodeSelector` la mande yon label okenn nœud pa genyen.

Si Events yo vid, gade si ou pa depase **ResourceQuota** namespace la: `kubectl describe quota`.
