Добрый день, есть миникубик, хотел подключить вместо манифестного стейтфул-сета БД - приложение через Helm (в основном для практики). Столкнулся с проблемой. Если использовать просто "helm install my-release bitnami/mysql" - всё окей. Если прописать mysql как зависимость - то она постоянно перезапускается. При этом логи у обеих одинаковые.
И так по порядку:

spoiler# Default values for my-app-chart.

# Declare variables to be passed into your templates.

# We usually recommend not to specify default resources and to leave this as a conscious

Chart.yaml
spoilerapiVersion: v2

description: A Helm chart for Kubernetes
# A chart can be either an 'application' or a 'library' chart.
#
# Application charts are a collection of templates that can be packaged into versioned archives
# to be deployed.
#
# Library charts provide useful utilities or functions for the chart developer. They're included as
# a dependency of application charts to inject those utilities and functions into the rendering
# pipeline. Library charts do not define any templates and therefore cannot be deployed.
type: application
# This is the chart version. This version number should be incremented each time you make changes
# to the chart and its templates, including the app version.
# Versions are expected to follow Semantic Versioning (https://semver.org/)
version: 0.1.0
# This is the version number of the application being deployed. This version number should be
# incremented each time you make changes to the application. Versions are not expected to
# follow Semantic Versioning. They should reflect the version the application is using.
appVersion: 1.16.0
dependencies:
- name: mysql
repository: https://charts.bitnami.com/bitnami
version: 8.0.0

Предугадывая несколько встречных вопросов:
1) Другой релиз ставить пробовал. Даже пробовал MariaDB.
2) Без NodePort и прочей шелухи в values - тоже пробовал.
Мучаюсь уже вторую ночь, подскажите пожалуйста.
