error installing oci8 in php8.1-apache docker image

[LucaMicelloneUnito]

I have an error when I use "FROM php:8.1-apache" and try to install oci8 for oracle.

I follow these steps;

1. download from oracle https://download.oracle.com/otn_software/linux/instantclient/216000/instantclient-basic-linux.x64-21.6.0.0.0dbru.zip and https://download.oracle.com/otn_software/linux/instantclient/216000/instantclient-sdk-linux.x64-21.6.0.0.0dbru.zip
2. unzip instantclient-basic-linux.x64-21.6.0.0.0dbru.zip and instantclient-sdk-linux.x64-21.6.0.0.0dbru.zip in folder /opt/oracle/instantclient
3. launch command echo 'instantclient,/opt/oracle/instantclient' | pecl install oci8-3.2.1

After this command there is an error: Fatal error: Uncaught Error: Call to undefined function exec() in /usr/local/lib/php/PEAR/Builder.php:465

[...]
Build complete.
Don't forget to run 'make test'.

The same command with php7.4-apache echo 'instantclient,/opt/oracle/instantclient' | pecl install oci8-2.2.0 works.

Try this

FROM php:8.1-apache
RUN apt update && apt install -y wget unzip libaio1 && rm -rf /var/lib/apt/lists/*
RUN cd /tmp/ && wget https://download.oracle.com/otn_software/linux/instantclient/216000/instantclient-basic-linux.x64-21.6.0.0.0dbru.zip && \
    wget https://download.oracle.com/otn_software/linux/instantclient/216000/instantclient-sdk-linux.x64-21.6.0.0.0dbru.zip && \
    unzip '*.zip' && \
    rm *.zip
RUN docker-php-ext-configure oci8 --with-oci8=instantclient,/tmp/instantclient_21_6/
RUN docker-php-ext-install oci8 && \
    echo /tmp/instantclient_21_6 > /etc/ld.so.conf.d/oracle.conf && \
    ldconfig
