Docker - Why do changes to the php configuration file not take effect?

Question

solve

When the configuration file is posted, the answer is obvious. The system has two PHP files.

1. php.ini-production

2. php.ini

I changed it to php.ini -_-!!!

- ./php-fpm/php.ini-production:/usr/local/etc/php/php.ini:ro

Tip Modify the configuration file without deleting docker, just restart docker docker-compose restart

Problem process

If the docker and php configuration files used change, use docker-compose rm and then docker-comose up. Why is there no change when looking at phpinfo()?

Answer 1

The reasonable explanation is that the php.ini you modified is not the php.ini loaded by running PHP in docker.

Check which path is loaded in php.ini.

Answer 2

docker rm will delete the modified configuration. You need to configure the local php.ini to map to docker in docker-compose.yml

Answer 3

Docker loads php in the image package, it is useless to modify the local one

Answer 4

php -i|grep php.ini to see if the loaded file is correct
