description: A Helm Chart to experiment with spiffe-vault within a Kubernetes cluster

# 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.
appVersion: "0.1.0"

Time to play with 'spiffe-vault':

kubectl exec -n {{ .Release.Namespace }} -i -t \
$(kubectl -n {{ .Release.Namespace }} get pods -l app.kubernetes.io/name={{ .Chart.Name }} -o jsonpath="{.items[0].metadata.name}") \
-c {{ .Chart.Name }} -- sh
