I'am try attach my NGINX configurations files (config, ssl certificates, and others) to my NGINX POD on AWS EKS (Elastic Kubernetes Service). Reading about this i'am using Persistence Volume and Persistence Volume Claim as demonstrated on follow tutorial (https://kubernetes.io/docs/tasks/configure-pod-container/configure-persistent-volume-storage/).
My scenario is: i need to attach the configurations files localizated on /mnt/data
into NGINX POD.
Persistent Volume:
apiVersion: v1
kind: PersistentVolume
metadata:
name: task-pv-volume
labels:
type: local
spec:
storageClassName: manual
capacity:
storage: 10Gi
accessModes:
- ReadWriteOnce
hostPath:
path: "/mnt/data"
Persistent Volume Claim:
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: task-pv-claim
spec:
storageClassName: manual
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 3Gi
NGINX POD:
apiVersion: v1
kind: Pod
metadata:
name: task-pv-pod
spec:
volumes:
- name: task-pv-storage
persistentVolumeClaim:
claimName: task-pv-claim
containers:
- name: task-pv-container
image: nginx
ports:
- containerPort: 80
name: "http-server"
volumeMounts:
- mountPath: "/usr/share/nginx/html"
name: task-pv-storage
After running the Persistent Volume, Persistent Volume Claim and NGINX POD and access the running NGINX POD with /bin/bash
the data that is located on my cluster at /mnt/data
should be inside the /usr/share/nginx/html
folder, correct? But when I access NGINX pod in the /usr/share/nginx/html
folder my /mnt/data
files are not there.
I'm new to development and maybe I'm missing something.
Thanks!
If you're creating a pod with nginx image the configuration created by the image will overwrite the existing files in the pod and which will also be reflected in the /mnt/data
path also.
You've to move your config files to usr/share/nginx/html after pod creation by using commands in pod.yml file. You can map /mnt/data
with tmp folder and use after creation commands to move files to usr/share/nginx/html
so everytime you create a new pod your config file will generate in desired path also
