I am transitioning from docker to Kubernetes. Had been volumes on docker to expose files needed by container, just like the example below to provide grafana container some files.
I am confused on how the same can be established in Kubernetes using volumeMounts and volumes, and how is it linked to PersistentVolumeClaim.
version: '3'
volumes:
grafana_app_data: {}
services:
grafana:
image: grafana/grafana:latest
volumes:
- grafana_app_data:/var/lib/grafana
- ./directory-on-local-machine/:/etc/grafana/provisioning/A Pod Spec that is equivalent ↔️ would be something like this:
apiVersion: v1
kind: Pod
metadata:
name: grafana-pod
spec:
containers:
- image: grafana/grafana:latest
name: grafana-container
volumeMounts:
- mountPath: /var/lib/grafana
name: grafana-app-data
- mountPath: /etc/grafana/provisioning
name: grafana-provisioning
volumes:
- name: grafana-app-data
hostPath:
path: /grafana-data
type: Directory
- name: grafana-provisioning
hostPath:
path: /directory-on-machiche
type: DirectoryThis is using basic hostPath, you can also use a local volume 💾 or any other type of supported volume depending on what you need. 💾📀💿💽
