AWS Codebuild build stage shows nginx was installed but container doesn't have nginx - aws-codebuild

Question

I'm new with AWS Codebuild and trying to deploy my docker application in EKS. On my Dockerfile I'm running RUN apk add nginx and build stage shows that it's being installed.
Step 6/24 : RUN apk add nginx
---> Running in cbd7a4e37bb7
(1/2) Installing pcre (8.44-r0)
(2/2) Installing nginx (1.18.0-r15)
Executing nginx-1.18.0-r15.pre-install
Executing nginx-1.18.0-r15.post-install
Executing busybox-1.32.1-r6.trigger
OK: 15 MiB in 34 packages
Removing intermediate container cbd7a4e37bb7
---> a890efd77e97
After the BUILD stage has been completed, I enter my EKS pod but didn't see any nginx under /etc
/etc # ls
ImageMagick-7 fstab issue my.cnf.d periodic securetty sysctl.d
alpine-release group logrotate.d mysql php7 services terminfo
apk group- modprobe.d network pkcs11 shadow udhcpd.conf
ca-certificates hostname modules openldap profile shadow- wgetrc
ca-certificates.conf hosts modules-load.d opt profile.d shells
conf.d init.d motd os-release protocols ssh
crontabs inittab mtab passwd resolv.conf ssl
fonts inputrc my.cnf passwd- rsyncd.conf sysctl.conf
I manually executed apk add nginx inside my pod and that's the only time nginx appeared under /etc
My AWS Codebuild is using the following configurations:
Managed image
OS: Amazon Linux 2
Runtime: Standard
Image: aws/codebuild/amazonlinux2-x86_64-standard:3.0
Image version: Always use the latest image for this runtime version
Privilaged: Enabled
Also,
I noticed that AWS Build doesn't execute the following COPY command in my Dockerfile:
COPY docker/php/php.ini /usr/local/etc/php/ (this works)
COPY docker/nginx/conf.d/default.conf /etc/nginx/conf.d/default.conf (this doesn't, probably because nginx didn't get installed on runtime)
COPY docker/nginx/docker-entrypoint.sh /usr/local/bin/docker-entrypoint-d9 (this doen't work.. still a mystery)
I hope I was able to provide the full details. Please let me know if you need more information. Thank you.
