<p>I am creating an InfluxDB deployment in a Kubernetes cluster (v1.15.2), this is my yaml file:</p>
<pre><code>apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: monitoring-influxdb
  namespace: kube-system
spec:
  replicas: 1
  template:
    metadata:
      labels:
        task: monitoring
        k8s-app: influxdb
    spec:
      containers:
      - name: influxdb
        image: registry.cn-hangzhou.aliyuncs.com/google_containers/heapster-influxdb-amd64:v1.5.2
        volumeMounts:
        - mountPath: /data
          name: influxdb-storage
      volumes:
      - name: influxdb-storage
        emptyDir: {}
---
apiVersion: v1
kind: Service
metadata:
  labels:
    task: monitoring
    # For use as a Cluster add-on (https://github.com/kubernetes/kubernetes/tree/master/cluster/addons)
    # If you are NOT using this as an addon, you should comment out this line.
    kubernetes.io/cluster-service: 'true'
    kubernetes.io/name: monitoring-influxdb
  name: monitoring-influxdb
  namespace: kube-system
spec:
  ports:
  - port: 8086
    targetPort: 8086
  selector:
    k8s-app: influxdb
</code></pre>
<p>And this is the pod status:</p>
<pre><code>$ kubectl get deployment -n kube-system
NAME                   READY   UP-TO-DATE   AVAILABLE   AGE
coredns                1/1     1            1           163d
kubernetes-dashboard   1/1     1            1           164d
monitoring-grafana     0/1     0            0           12m
monitoring-influxdb    0/1     0            0           11m
</code></pre>
<p>Now, I've been waiting 30 minutes and there is still no pod available, how do I check the deployment log from command line? I could not access the Kubernetes dashboard now. I am searching a command to get the pod log, but now there is no pod available. I already tried to add label in node:</p>
<pre><code>kubectl label nodes azshara-k8s03 k8s-app=influxdb
</code></pre>
<p>This is my deployment describe content:</p>
<pre><code>$ kubectl describe deployments monitoring-influxdb -n kube-system

<p>This is another way to get logs:</p>
<pre><code>$ kubectl -n kube-system logs -f deployment/monitoring-influxdb
error: timed out waiting for the condition
</code></pre>
<p>There is no output for this command:</p>
<pre><code>kubectl logs --selector k8s-app=influxdb
</code></pre>
<p>There is all my pod in kube-system namespace:</p>
