I got an error in my Deoloyment.ysml file. I have made env in this file and assign values in values file. I got a syntax error in this file

With AKIRA_HTTP_PORT: "8080" in values.yaml, in the env variables write:

env:
  - name:  AKIRA_HTTP_PORT
    value: {{ .Values.website.port | quote }}

It should have to work

Answer to your problem is available in Helm documentation QUOTE STRINGS, DON’T QUOTE INTEGERS.

When you are working with string data, you are always safer quoting the strings than leaving them as bare words:

name: {{ .Values.MyName | quote }}

But when working with integers do not quote the values. That can, in many cases, cause parsing errors inside of Kubernetes.

port: {{ .Values.Port }}

This remark does not apply to env variables values which are expected to be string, even if they represent integers:

env:
 - name: HOST
   value: "http://host"
 - name: PORT
   value: "1234"

I'm assuming you have put the port value of AKIRA_HTTP_PORT inside quotes, that's why you are getting the error.

You can read the docs about Template Functions and Pipelines.
