创建一个NOTES.txt文件

该部分会介绍为chart用户提供说明的Helm工具。在helm install或helm upgrade命令的最后，Helm会打印出对用户有用的信息。使用模板可以高度自定义这部分信息。

要在chart添加安装说明，只需创建templates/NOTES.txt文件即可。该文件是纯文本，但会像模板一样处理，所有正常的模板函数和对象都是可用的。

让我们创建一个简单的NOTES.txt文件：

Thank you for installing {{ .Chart.Name }}.

Your release is named {{ .Release.Name }}.

To learn more about the release,try:

  $ helm statue {{ .Release.Name }}

  $ helm get all {{ .Release.Name }}

Thank you for installing {{ .Chart.Name }}.Your release is named {{ .Release.Name }}.To learn more about the release, try:$ helm status {{ .Release.Name }}$ helm get all {{ .Release.Name }}

现在如果我们执行helm install rude-cardinal ./mychart会在底部看到：

RELEASES:

==> v1/Secret

NAME TYPE DATA AGE

rude-cardinal-secret 0paque 1 0s

==> v1/ConfigMap

NAME DATA AGE

rude-cardinal-configmap 3 0s

NOTES:

Thank you for installing mychart.

Your release is named rude-cardinal.

To learn more about the release,try:

  $ helm status rude-cardinal

  $ helm get all rude-cardinal

RESOURCES:
==> v1/Secret
NAME                   TYPE      DATA      AGE
rude-cardinal-secret   Opaque    1         0s==> v1/ConfigMap
NAME                      DATA      AGE
rude-cardinal-configmap   3         0sNOTES:
Thank you for installing mychart.Your release is named rude-cardinal.To learn more about the release, try:$ helm status rude-cardinal$ helm get all rude-cardinal

使用NOTES.txt这种方式是给用户提供关于如何使用新安装的chart细节信息的好方法。尽管并不是必须的，强烈建议创建一个NOTES.txt文件。
