unable to mount a folder inside container(pod) to host folder in kubernetes .

[sandeepn...@gmail.com]

Hi i am trying to mount the volume from container to host and throwing an exception to me .
My
yaml is like this

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: vthree-f3dev-app-pod-volumes
labels:
component: apiserver
provider: kubernetes
spec:
replicas: 1
selector:
template:
metadata:
labels:
component: apiserver
provider: kubernetes
spec:
containers:
- name: f3dev
image: XXXXXXXXXXXXXXXXXX
ports:
- containerPort: 8443
volumeMounts:
- mountPath: /etc/tomcat8/logs
name: test-volume
env:
- name : VTHREE_F3DEV_APP_POD_SERVICE_CONTEXT_ROOT
value : "f3dev"
- name : SOLR_SERVC_CONTEXT_ROOT
value : "solr"
volumes:
- name: test-volume
hostPath:
path: /logs/f3dev-pod-logs

And i am getting error while i am trying to deploy this

The Deployment "vthree-f3dev-app-pod-volumes" is invalid: spec.template.spec.containers[0].volumeMounts[0].name: Not found: "test-volume"

my kubctl version

kubectl --version
Kubernetes v1.5.2

Please suggest me where i am doing wrong .

It looks like the volumes section is not indented correctly. It should be indented to the same level as containers as it is part of the PodSpec[1].

As the error says, it has nothing to do with volumes but with the CMD or entry point of your docker image. The command it executes prints the error you pasted:
