+# volbench on k8s
+Standardized benchmarking for volumes hosted on kubernetes
+
+## how does it look like
+To guarantee the simplest usage possible, the k8s version is composed of two files:
+- ```volbench.sh``` which is the actual bash script calling ```fio``` with the relevant benchmarking profile
+- ```volbench.yaml``` which is a standard yaml configuration file 
+
+Note: ```volbench.sh``` has very few changes from the CLI version to run smoothly as a pod on k8s.
+
+## what does ```volbench.yaml``` do
+When applying the file towards a k8s cluster, it will create: 
+- a namespace called ```volbench```
+- a persistent volume claim called ```volbenchtemp1``` linked to the created namespace
+- a pod called ```volbench-runner``` within the created namespace consuming the persistent volume
+
+Here is the full yaml file:
+```yaml 
+apiVersion: v1
+kind: Namespace
+metadata:
+  name: volbench
+---
+apiVersion: v1
+kind: PersistentVolumeClaim
+metadata:
+  name: volbenchtemp1
+  namespace: volbench
+spec:
+  storageClassName: "fast"
+  accessModes:
+    - ReadWriteOnce
+  resources:
+    requests:
+      storage: 1Gi

+      args: ["-c", 'apk update && apk add git fio bash --no-cache; git clone --single-branch --branch containerized http://github.com/rovandep/volbench.git; /volbench/k8s/volbench.sh; sleep 36000']
+      volumeMounts:
+        - mountPath: /tmp
+          name: tmp1
+      env:
+      - name: FIO_files
+        value: "/tmp/volbenchtest1 /tmp/volbenchtest2"
+      - name: FIO_size
+        value: "1MB"
+      - name: FIO_ramptime
+        value: "1"
+      - name: FIO_runtime
+        value: "5"
+      - name: FIO_rwmixread
+        value: "75"
+      - name: FIO_fdatasync
+        value: "0"
+  volumes:
+    - name: tmp1
+      persistentVolumeClaim:
+        claimName: volbenchtemp1
+```
+
+Note: there are environment variables defined under ```env:``` within the YAML configuration file defining the ```fio``` benchmarking profile.
+
+Here is an overview of the ones shipped in the configuraiton file that allows a very fast run to check that all is working as expected.
+
+
+## how to use it
+In a nutshell, from the above YAML output:
+- the ```storageClassName``` might need to be change to match the existing ```storageClassName``` on the targeted k8s.  
+- the ```env``` field might need to be change to match the desired ```fio``` benchmarking profile.
