OCI8 extension for php:8.0-fpm-alpine in Dockerfile

Question

I'm trying to install and enable OCI8 in dockerfile for php:8.0-fpm-alpine image to ..

This is a part of my Dockerfile:

ARG PHP_VERSION=8.0

FROM php:${PHP_VERSION}-fpm-alpine AS api_platform_php

# Install Oracle Instantclient
RUN mkdir /usr/lib/oracle
RUN apk --no-cache add libaio curl && \
    curl -o instantclient.zip https://download.oracle.com/otn_software/linux/instantclient/217000/instantclient-basic-linux.x64-21.7.0.0.0dbru.zip -SL && \
    curl -o instantclient-sdk.zip https://download.oracle.com/otn_software/linux/instantclient/217000/instantclient-sdk-linux.x64-21.7.0.0.0dbru.zip -SL && \
    unzip instantclient.zip && unzip instantclient-sdk.zip &&\
    mv instantclient_21_7 /usr/lib/oracle/ && \
    rm instantclient.zip && rm instantclient-sdk.zip && \
    cd /usr/lib/oracle/instantclient_21_7 \
        && ln -sf libclntsh.so.21.1 libclntsh.so \
        && ln -sf libclntshcore.so.21.1 libclntshcore.so \
        && ln -sf libocci.so.21.1 libocci.so \
        && rm -rf *.zip

#ENV LD_LIBRARY_PATH /usr/lib/oracle/instantclient
#ENV ORACLE_BASE /usr/lib/oracle/instantclient
#ENV TNS_ADMIN /usr/lib/oracle/instantclient
#ENV ORACLE_HOME /usr/lib/oracle/instantclient

# Install Oracle extensions
RUN docker-php-ext-configure pdo_oci --with-pdo-oci=instantclient,/usr/lib/oracle/instantclient_21_7 \
       && echo 'instantclient > /usr/lib/oracle/instantclient_21_7/' \
       && ldconfig | pecl install oci8-3.0.1 \
       && docker-php-ext-install \
               pdo_oci \
       && docker-php-ext-enable \
               oci8

The result is as follow :

configure: error: Oracle Instant Client directory /usr/lib/oracle/.../client64/lib libraries not found. Try --with-oci8=instantclient,DIR

Thanks for your help

I have Succeed to enable the extension...
I think my issue was the order of the installation.
