## Just some random #kubectl commands for myself. I have tested these on 1.20 \<\> 1.25

#### Get all ingress logs (if your ingress is nginx)

```
kubectl logs -n ingress-nginx -l app.kubernetes.io/name=ingress-nginx

```

#### Get all logs from Deployment

```
kubectl logs deployment/ -n --watch

```

#### Why is the pod stuck in “ContainerCreating”?

```
kubectl get events --sort-by=.metadata.creationTimestamp --watch

```

#### Restart your deployment, nice and clean

```
kubectl rollout restart deployment/ -n 

```

#### Check which namespaces are using the most disk space

```
kubectl get namespace --no-headers | xargs -I {} sh -c 'echo {}; kubectl get pods -n {} --no-headers | xargs -I {} sh -c "kubectl logs {} -n {} | wc -c"' | awk '{print $1" "($2/1024/1024)" MB"}' | sort -k2 -n -r | head

```

#### Check if any pods are using a lot of disk space

```
kubectl get pods --all-namespaces -o json | jq '.items[].spec.containers[].resources.requests.storage' | grep -v null

```

#### Check the Kubernetes event logs for any disk-related errors

```
kubectl get events --field-selector involvedObject.kind=Node,reason=OutOfDisk

```

I'll add more when I find more usefull stuff
