Description of problem:

When switching from ubi8 to ubi9 the change from mod_php to php fpm breaks configs with environment variables

Version-Release number of selected component (if applicable):


How reproducible:

Dockerfile.ubi8


# ubi8 
FROM registry.access.redhat.com/ubi8/php-80

USER 0
ADD . /tmp/src
RUN chown -R 1001:0 /tmp/src
USER 1001

# Install the dependencies
RUN /usr/libexec/s2i/assemble

# Set the default command for the resulting image
CMD /usr/libexec/s2i/run
Dockerfile.ubi9


# ubi9
FROM registry.access.redhat.com/ubi9/php-80

USER 0
ADD . /tmp/src
RUN chown -R 1001:0 /tmp/src
USER 1001

# Uncomment this sed to fix the environment variables
# RUN sed -i "s/.clear_env.=.*/clear_env = no/g" /etc/php-fpm.d/www.conf

# Install the dependencies
RUN /usr/libexec/s2i/assemble

# Set the default command for the resulting image
CMD /usr/libexec/s2i/run
With those two docker files in the same directly build out a phpinfo file


cat <<EOF >>phpinfo.php
<?php

phpinfo();

?>
EOF
UBI8 baseline of expected results
Now run the ubi8 image to see the expected baseline


docker build . -f Dockerfile.ubi8 -t test8:latest
podman run -e FOO=BAR -p 8080:8080 test8:latest
open a browser to http://127.0.0.1:8080/phpinfo.php


note:



in loaded modules "mod_php"

environment variable FOO is set to bar


UBI9 showing issue
docker build . -f Dockerfile.ubi9 -t test9:latest
podman run -e FOO=BAR -p 8080:8080 test9:latest
open a browser to http://127.0.0.1:8080/phpinfo.php


note:



no loaded modules "mod_php"

php-fpm now set to active in cgi

environment varible FOO is now missing


From here you can edit the Dockerfile.ubi9 and uncomment the sed line/rebuild/rerun and see the normal expected results.
