# Panfactum Changelog — edge.24-05-30

> Reduces default Vault storage size, adds Loki logging backend, introduces PVC Autoresizer for automatic EBS volume expansion, and fixes Karpenter scheduling issues.

## Highlights

- Default `vault_storage_size_gb` changed from `20` to `2` — manual update required if you used the old default
- New [`kube_logging`](https://panfactum.com/docs/edge/reference/infrastructure-modules/direct/kubernetes/kube_logging) module with Loki backend (Alpha)
- New [`kube_pvc_autoresizer`](https://panfactum.com/docs/edge/reference/infrastructure-modules/direct/kubernetes/kube_pvc_autoresizer) for automatic EBS volume expansion

## Breaking Changes

- The default for `vault_storage_size_gb` in [`kube_vault`](https://panfactum.com/docs/edge/reference/infrastructure-modules/direct/kubernetes/kube_vault) has been changed from `20` to `2` in order to improve resource utilization. If
  - Impacts: iac-module `kube_vault` — Default vault_storage_size_gb changed from 20 to 2

## Additions

- (Alpha) Added the [Loki](https://grafana.com/docs/loki/latest/) logging backend via [`kube_logging`](https://panfactum.com/docs/edge/reference/infrastructure-modules/direct/kubernetes/kube_logging) and the [Alloy](https://grafana.com/docs/alloy/latest/) log collector via [`kube_alloy`](https://panfactum.com/docs/edge/reference/infrastructure-modules/direct/kubernetes/kube_alloy).
  - Impacts: iac-module `kube_logging` — New module providing Loki logging backend
  - Impacts: iac-module `kube_alloy` — New module providing Alloy log collector
- The [PVC Autoresizer](https://github.com/topolvm/pvc-autoresizer) has been added via the [`kube_pvc_autoresizer`](https://panfactum.com/docs/edge/reference/infrastructure-modules/direct/kubernetes/kube_pvc_autoresizer) module in order to automatically expand EBS volumes as they fill
  - Impacts: iac-module `kube_pvc_autoresizer` — New module for automatic EBS volume expansion
- Added validation for phone number format in [`aws_registered_domains`](https://panfactum.com/docs/edge/reference/infrastructure-modules/direct/aws/aws_registered_domains).
  - Impacts: iac-module `aws_registered_domains` — Added phone number format validation

## Fixes

- Resolved issue where scheduling constraints could not be resolved for components deployed before Karpenter ([#41](https://github.com/Panfactum/stack/issues/41)).
  - Reference (issue-report): [Scheduling constraints unresolvable for pre-Karpenter components](https://github.com/Panfactum/stack/issues/41)
