# Garage helm3 chart
This chart deploys garage on a kubernetes cluster.
## Deploying
With default options:
```bash
helm install --create-namespace --namespace garage garage ./garage
```
With custom values:
```bash
helm install --create-namespace --namespace garage garage ./garage -f values.override.yaml
```
## Overriding default values
All possible configuration values can be found in [values.yaml](garage/values.yaml).
This is an example `values.overrride.yaml` for deploying in a microk8s cluster with a https s3 api ingress route:
```yaml
# Start 4 instances (StatefulSets) of garage
replicaCount: 4
# Override default storage class and size
persistence:
meta:
storageClass: "openebs-hostpath"
size: 100Mi
data:
storageClass: "openebs-hostpath"
size: 1Gi
ingress:
s3:
api:
enabled: true
className: "public"
annotations:
cert-manager.io/cluster-issuer: "letsencrypt-prod"
nginx.ingress.kubernetes.io/proxy-body-size: 500m
hosts:
- host: s3-api.my-domain.com
paths:
- path: /
pathType: Prefix
tls:
- secretName: garage-ingress-cert
hosts:
- s3-api.my-domain.com
```
## Removing
```bash
helm delete --namespace garage garage
```
Note that this will leave behind custom CRD `garagenodes.deuxfleurs.fr`, which must be removed manually if desired.

# 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.
# It is recommended to use it with quotes.
