In order to save the value of the variable as Secret<\/strong>, the variable must be encoded in base64<\/strong>, for this we use "_helpers.tpl<\/strong>"<\/p>\n

For example, we need to save the value of the variable "applicationSecret<\/strong>"<\/p>\n

values.yaml:<\/h3>\n
\r\n# Default values for artem-services.\r\n# This is a YAML-formatted file.\r\n# Declare variables to be passed into your templates.\r\n\r\nreplicaCount: 1\r\nnamespace: default\r\n\r\nimage:\r\n  repository: XXXXXXXXXXXX.dkr.ecr.eu-east-1.amazonaws.com\/artem-services\r\n  tag: 1.0.1\r\n  pullPolicy: IfNotPresent\r\n\r\nnameOverride: ""\r\nfullnameOverride: "artem-services"\r\n\r\napplicationSecret: |\r\n  var1=value1\r\n  var2=value2\r\n  var3=value3\r\n  var4=value4\r\n<\/pre>\n
 <\/p>\n
Add the following to "_helpers.tpl<\/strong>":<\/p>\n
_helpers.tpl:<\/h3>\n
\r\n{{- define "applicationSecret" }}\r\n{{- printf .Values.applicationSecret | b64enc }}\r\n{{- end }}\r\n<\/pre>\n
 <\/p>\n
Now in the "templates<\/strong>" directory, create the file "secret.yaml<\/strong>"<\/p>\n
secret.yaml:<\/h3>\n
