IPv6 is not enabling

[dcshiman]

Describe the bug

I am trying to enable IPv6 on the container, but when the container starts up it give me the following message even though I am using the default /etc/nginx/conf.d/default.conf file.

10-listen-on-ipv6-by-default.sh: info: /etc/nginx/conf.d/default.conf differs from the packaged version

To reproduce

Steps to reproduce the behavior:

1. Deploy NGINX Unprivileged Docker image nginxinc/nginx-unprivileged:1.22.1
2. View output/logs/configuration on '10-listen-on-ipv6-by-default.sh: info: /etc/nginx/conf.d/default.conf differs from the packaged version'
3. See error

Expected behavior

IPv6 should be enabled by changing port to listen [::]:8080

Your environment

• Version of Docker: Using AWS Bottlerocket AMI on AWS EKS kubernetes v1.23 on IPv6
• Version of the NGINX Unprivileged Docker image nginxinc/nginx-unprivileged:1.22.1
• Target deployment kubernetes

Additional context

I would am using the container with kuberhealthy test run. Which dose not allow to change the entrypoint of the container. It would be helpful if we can turn on IPv6 by Environment variable NGINX_PORT
