description: A Helm chart for Kubernetes
4+
# A chart can be either an 'application' or a 'library' chart.
5+
#
6+
# Application charts are a collection of templates that can be packaged into versioned archives
7+
# to be deployed.
8+
#
9+
# Library charts provide useful utilities or functions for the chart developer. They're included as
10+
# a dependency of application charts to inject those utilities and functions into the rendering
11+
# pipeline. Library charts do not define any templates and therefore cannot be deployed.
12+
type: application
13+
# This is the chart version. This version number should be incremented each time you make changes
14+
# to the chart and its templates, including the app version.
15+
# Versions are expected to follow Semantic Versioning (https://semver.org/)
16+
version: 0.1.0
17+
# This is the version number of the application being deployed. This version number should be
18+
# incremented each time you make changes to the application. Versions are not expected to
19+
# follow Semantic Versioning. They should reflect the version the application is using.
20+
# It is recommended to use it with quotes.

> helm charts for qryn
5+
## Overview
6+
This Helm chart provides Kubernetes deployment configurations for [Qryn](https://github.com/metrico/qryn), a data visualization and exploration tool. [Qryn](https://github.com/metrico/qryn) is a polyglot, lighweight, multi-standard drop-in observability framework for Logs, Metrics and Traces
7+
8+
## Usage
9+
To deploy [Qryn](https://github.com/metrico/qryn) using this Helm chart, use the following command:
10+
11+
bash
12+
Copy code
13+
helm install qryn-release qryn-helm
14+
For customization, you can provide a values.yaml file or use --set flags to override specific configurations during installation.
15+
16+
17+
Feel free to modify the configurations based on your requirements and environment.
18+
19+
