How to get all environment variables？

[kadifu]

Hello, I use the tag fpm-apache mirror. I can see in the documentation that you can use 'php-envvars' to view PHP-related environment variables. But what command can I use to view all environment variables, such as Apache-related configurations?

[shinsenter]

You can use the built-in Linux command printenv to list all environment variables.

To run it in your container from the host machine:

docker exec -it <your_container_id> printenv
