I’m using this approach in OpenShift, so it should be applicable in Kubernetes as well.
Try to put your script into a configmap key/value, mount this configmap as a volume and run the script from the volume.
apiVersion: batch/v1
kind: Job
metadata:
name: hello-world-job
spec:
parallelism: 1
completions: 1
template:
metadata:
name: hello-world-job
spec:
volumes:
- name: hello-world-scripts-volume
configMap:
name: hello-world-scripts
containers:
- name: hello-world-job
image: alpine
volumeMounts:
- mountPath: /hello-world-scripts
name: hello-world-scripts-volume
env:
- name: HOME
value: /tmp
command:
- /bin/sh
- -c
- |
echo "scripts in /hello-world-scripts"
ls -lh /hello-world-scripts
echo "copy scripts to /tmp"
cp /hello-world-scripts/*.sh /tmp
echo "apply 'chmod +x' to /tmp/*.sh"
chmod +x /tmp/*.sh
echo "execute script-one.sh now"
/tmp/script-one.sh
restartPolicy: Never
---
apiVersion: v1
items:
- apiVersion: v1
data:
script-one.sh: |
echo "script-one.sh"
date
sleep 1
echo "run /tmp/script-2.sh now"
/tmp/script-2.sh
script-2.sh: |
echo "script-2.sh"
sleep 1
date
kind: ConfigMap
metadata:
creationTimestamp: null
name: hello-world-scripts
kind: List
metadata: {}
