Partially reconstruct manifests in the event you lost them but still have actual deployment pods running.

Here is how you can partially reconstruct the deleted manifests to make sure your provider will keep monitoring them, withdrawing from their leases as well as allow users to re-send their deployment manifest (without redeploying) to restore it & their ingresses (uri's), avoiding the Pod restart, hence keeping the ephemeral data on a Pod.

1. Partially reconstruct missing manifests

This reconstruction is based on existing namespaces, there is no way to entirely reconstruct the manifests unless they were manually backed up.

Akash Provider safeguard script against freeloaders

This script issues akash tx market lease withdraw only against leases which ran out of balance.

Motivation

The deployment gets automatically closed when it runs out of balance in escrow account. But the balance settlement occurs only after a lease withdraw transaction.

Without timely withdrawal from the escrow accounts freeloaders can deploy an expensive deployment

Still errors. I believe python3.5 is way too old for the Ansible. I suggest latest stable Ubuntu version.
