# Kasm DB Upload Job
#
# Use this to upload a Kasm database backup file into a PVC so it can be
# consumed by the db-restore.yaml job.
# Typical use cases:
#   - Migrating from a VM-based Kasm deployment to Kubernetes
#
# Prerequisites:
#   - This job must be deployed in the same namespace as your Kasm Helm release.
#   - Run this job before applying db-restore.yaml.
#
# Field reference:
#   image             — Replace with your Kasm version, e.g. kasmweb/api:1.19.0
#   storageClassName  — Storage class for the backup PVC. Commented out by default to use the namespace
#                       default. Uncomment and set a value to use a specific storage class.
#
# Before applying:
#   1. Replace all values marked with # <-- REPLACE
#   2. Apply with:  kubectl apply -n {NAMESPACE} -f examples/db-upload.yaml
#   3. Upload your backup file with:
#        kubectl cp -n {NAMESPACE} /path/to/kasm_dump.tar {UPLOAD-POD-NAME}:/data/kasm-db-dump/kasm_dump.tar
#      Retrieve the pod name with: kubectl get pods -n {NAMESPACE}
#   4. Monitor upload completion with: kubectl logs -f job/upload -n {NAMESPACE}
