Build alpine-swoole will be failed for PHP 8.1 - alpine 3.16 - swoole 5.0.2 due to no php command.

docker compose build alpine-swool

PHP_VERSION=8.1
PHP_BUILD_VERSION=8
ALPINE_VERSION=3.16
SW_VERSION=v5.0.2

Solution

If change php -> php81 , may it works.
May we can try to add execution file name as environment variable to build docker image.

RUN php81 -v & sleep 3 \
    && php81 -m & sleep 3 \
    && php81 --ri swoole & sleep 3 \
    && php81 --ri Zend\ OPcache & sleep 3 \
    && composer & sleep 3 \
    && echo -e "\033[42;37m Build Completed :).\033[0m\n"
