description: A Helm chart for Kubernetes

# 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.
13+
type: application
14+
15+
# This is the chart version. This version number should be incremented each time you make changes
16+
# to the chart and its templates, including the app version.
17+
# Versions are expected to follow Semantic Versioning (https://semver.org/)
18+
version: 0.1.0
19+
20+
# This is the version number of the application being deployed. This version number should be
21+
# incremented each time you make changes to the application. Versions are not expected to
22+
# follow Semantic Versioning. They should reflect the version the application is using.
23+
# It is recommended to use it with quotes.

Thank you for installing {{ .Chart.Name }}!
2+
3+
Your release is named {{ .Release.Name }}.
4+
5+
To learn more about the release, try:
6+
7+
$ helm status {{ .Release.Name }}
8+
$ helm get all {{ .Release.Name }}
9+
10+
The timeserver application has been deployed with the following components:
11+
- Deployment: {{ include "app.fullname" . }}
12+
- Service: {{ include "app.fullname" . }}
13+
{{- if .Values.createConfigMap }}
14+
- ConfigMap: {{ include "app.configMapName" . }}
15+
{{- end }}
16+
{{- if .Values.createSecret }}
17+
- Secret: {{ include "app.secretName" . }}
18+
{{- end }}
19+
20+
To access the timeserver service from within the cluster:
21+
22+
$ kubectl run -it --rm debug --image=busybox --restart=Never -- wget -O- http://{{ include "app.fullname" . }}:{{ .Values.service.port }}
23+
24+
To get the application URL:
25+
{{- if eq .Values.service.type "NodePort" }}
26+
export NODE_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ include "app.fullname" . }})
27+
export NODE_IP=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
28+
echo http://$NODE_IP:$NODE_PORT
29+
{{- else if eq .Values.service.type "LoadBalancer" }}
30+
NOTE: It may take a few minutes for the LoadBalancer IP to be available.
31+
You can watch the status by running:
32+
$ kubectl get --namespace {{ .Release.Namespace }} svc -w {{ include "app.fullname" . }}
33+
34+
export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ include "app.fullname" . }} --template "{{"{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}"}}")
35+
echo http://$SERVICE_IP:{{ .Values.service.port }}
36+
{{- else if eq .Values.service.type "ClusterIP" }}
37+
$ kubectl port-forward --namespace {{ .Release.Namespace }} svc/{{ include "app.fullname" . }} 8080:{{ .Values.service.port }}
38+
39+
Then access the application at: http://127.0.0.1:8080
