32+
Alternative: build the image individually and set optional build args (LIBRDKAFKA_VERSION default = v1.5.3, RDKAFKA_EXT_VERSION default =
33+
4.1.x for php74 / 5.x for php80)
34+
35+
docker-compose build --no-cache --pull --build-arg LIBRDKAFKA_VERSION="v1.5.3" --build-arg RDKAFKA_EXT_VERSION="4.1.1" php74
36+
37+
Test - should show latest 7.4 version
38+
39+
docker-compose run php74 php -v
40+
41+
Test - should show ```FFI``` in modules list
42+
43+
docker-compose run php74 php -m
44+
45+
Test ffi librdkafka binding - should show current version of librdkafka:
46+
47+
docker-compose run php74 php examples/version.php
48+
49+
Test - should show ```rdkafka``` in modules list
50+
