Adds a Kubernetes-ZVMA companion to the existing Windows-ZVM recipe:
- scripts/examples/zerto-zvma-send.ps1 - Zerto-side sender for both
pre and post phases, packages the Zerto* env vars into a structured
JSON body and POSTs to a {phase}-templated webhook URL.
- scripts/examples/zerto-receiver-notify.ps1 - server-side receiver
that posts a Slack/Teams notification, with phase-aware formatting
and ZertoForce highlighted on pre.
- scripts/examples/zerto-receiver-vm-healthcheck.ps1 - server-side
receiver that pings + port-probes each VM in VmDisplayNames after
failover and writes a per-run JSON report.
- scripts/examples/send-env-vars.ps1 + save-env-vars.ps1 - generic
env-dump client/receiver pair (the diagnostic that surfaced what
the ZVMA scripts-service container exposes).
- docs/recipes/zerto-zvma-pre-post.md - full walkthrough mirroring
the existing Windows-ZVM recipe's structure.
- README.md and docs/README.md - link the new recipe and examples.

.SYNOPSIS
|
|
Zerto pre/post script (ZVMA / Linux scripts-service edition). Reads the
|
|
Zerto-injected environment variables and POSTs them to a Webhook Server
|
|
endpoint as a structured JSON payload.
|
|
|
|
.DESCRIPTION
|
|
Drop into a VPG's Recovery Scripts in the ZVM UI:
|
|
VPG settings -> Recovery -> Scripts -> Pre / Post Recovery Script
|
|
Path: /app/scripts-files/zerto-zvma-send.ps1
|
|
Parameters: -Phase pre (or -Phase post on the post-recovery slot)
|
|
|
|
Configure $WebhookUrl + $Bearer (or use the -WebhookUrl / -Bearer params
|
|
so one script file can serve multiple VPGs / endpoints).
|
|
|
|
Async by default - the call returns 202 in milliseconds and the actual
|
|
work runs in the webhook server's background, so the VPG sequence is
|
|
never blocked by slow downstream actions (DNS, notifications, etc.).
|
|
|
|
.NOTES
|
|
The scripts-service container has pwsh 7 and curl available. This script
|
|
uses Invoke-RestMethod to keep things native to PowerShell.
