Docker chown folder on volume binded with magento - docker

Question

I am actually blocked because when I add this command in my Dockerfile
"RUN ln -s /etc/nginx/sites-available/local.magento /etc/nginx/sites-enabled" to activate my virtual host, I have always the same error
"nginx: [emerg] open() "/var/www/html/magento2/site/nginx.conf.sample" failed (13: Permission denied) in /etc/nginx/sites-enabled/local.magento:10"
Although I have made add this command "mkdir -p /var/www/html;
chmod 777 -R /var/www/html;
chown rootless:rootless /var/www/html; ", I have read that we cannot make a chown for an other user on a folder already binded by a volume. I have read every posts on that and I tried every methods without succeed. So I guess I must not use a correct method elsewhere.
Could you please tell me what's wrong with my dockerfile?

I have tried many things regarding the existing topics on that but nothing to do...
Don't judge the details on my dockerfile like my password or the comments, it's a test file nothing else:)
Thanks in advance for your help
