How to set the 'secure' and the 'httpOnly' attribute for any session cookie from DOCKERFILE

[Ibra95ak-pomechain]

I'm using this dockerfile image for my project and I want to set the 'secure' and the 'httpOnly' attribute to true.

My main goal is to have them as default values for all cookies and sessions on the server.

I added the ENV variables corresponding to that :

ENV PHP_SESSION_COOKIE_SECURE=On
ENV PHP_SESSION_COOKIE_PATH=/
ENV PHP_SESSION_COOKIE_HTTPONLY=On

Also, I tried :

ENV PHP_SESSION_COOKIE_SECURE=true
ENV PHP_SESSION_COOKIE_PATH=/
ENV PHP_SESSION_COOKIE_HTTPONLY=true

And still, I see them set as false when I browse the website.

Here is my dockerfile:
