Fix/podspec enable name handling #13
Conversation
The serviceAccount values were changed to a (create/name), but the podspec was still expecting a flat string. This fix restores the correct serviceAccountName mapping.
Summary of ChangesHello @PhennyOpsta, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request streamlines the management of Kubernetes ServiceAccounts within the Helm chart ecosystem. It introduces a more direct way to specify ServiceAccount names, moving from a nested object structure to a simple string value. This change simplifies the ServiceAccount creation template and its integration into PodSpecs, ensuring a more consistent and easier-to-manage configuration across various applications leveraging the common chart.

Code Review
This pull request aims to simplify the ServiceAccount configuration. However, a potential YAML injection vulnerability was identified in the ServiceAccount template where user-supplied values are used without proper quoting, which could allow for the injection of malicious metadata. Additionally, the current implementation introduces a significant regression by removing the ability to use pre-existing ServiceAccounts and also removes standard labels from created resources. Several chart versions have also been incorrectly decremented, which needs to be addressed.

The chart version has been decremented from 0.78.0 to 0.77.0. This violates Semantic Versioning principles and can break dependency management and deployment pipelines. The version should be incremented to reflect the new changes. Given this is a feature change, a minor version bump is appropriate.

A YAML injection vulnerability exists here as the user-provided value .Values.serviceAccount is rendered directly without quoting, potentially allowing for malicious metadata injection. It is critical to use the quote function to prevent this. Furthermore, the current ServiceAccount creation logic in this block introduces a regression by removing the ability to use existing ServiceAccounts and omitting standard labels, which are essential for resource management.

The description for serviceAccount is misleading. It states "If not specified, the chart will automatically create one." However, the template logic in _serviceaccount.yaml ({{- if .Values.serviceAccount }}) will only create a service account if a name is provided. If it's not specified (i.e., an empty string), no service account is created. The description should be updated to accurately reflect the actual behavior of the chart.
