Nginx, PHP-8.2, SQL Server 2019, Alpine, Custom OpenSSL Config

This article covers how to build a docker image that supports sqlsrv, pdo_sqlsrv PHP module for connecting PHP to Microsoft SQL Server 2019. Maybe, this flow can be used in another version.

Kindly try guys, if you have new suggestions, please comment. Thanks

- Dockerfile

FROM webdevops/php-nginx:8.2-alpine

RUN apk add autoconf make g++ unixodbc-dev gpg --no-cache

COPY odbc18.sh .
COPY ssl.sh .

RUN bash ssl.sh

RUN bash odbc18.sh

RUN pecl install sqlsrv && \
    pecl install pdo_sqlsrv

RUN echo extension=pdo_sqlsrv.so >> /opt/docker/etc/php/php.ini && \
    echo extension=sqlsrv.so >> /opt/docker/etc/php/php.ini

- odbc18.sh

case $(uname -m) in

    arm64)   architecture="arm64" ;;
    *) architecture="unsupported" ;;
esac
if [[ "unsupported" == "$architecture" ]];
then
    echo "Alpine architecture $(uname -m) is not currently supported.";
    exit;
