# FullStack Devop's collection of helm charts
2+
3+
## Usage
4+
5+
[Helm](https://helm.sh) must be installed to use the charts. Please refer to
6+
Helm's [documentation](https://helm.sh/docs) to get started.
7+
8+
Once Helm has been set up correctly, add the repo as follows:
9+
10+
helm repo add fsops http://fullstack-devops.github.io/helm-charts/
11+
12+
If you had already added this repo earlier, run `helm repo update` to retrieve
13+
the latest versions of the packages. You can then run `helm search repo
14+
fsops` to see the charts.
15+
16+
To install the <chart-name> chart:
17+
18+
helm install my-<chart-name> fsops/<chart-name>
19+
20+
To uninstall the chart:
21+
22+
helm delete my-<chart-name>

# A chart can be either an 'application' or a 'library' chart.
6+
#
7+
# Application charts are a collection of templates that can be packaged into versioned archives
8+
# to be deployed.
9+
#
10+
# Library charts provide useful utilities or functions for the chart developer. They're included as
11+
# a dependency of application charts to inject those utilities and functions into the rendering
12+
# 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
