Docker Set environment variables in ubuntu cant access through php getenv

I've created a Docker container with an Ubuntu base image. Setting the environment variables through a .env file. When running the container, I can see the variables being passed through using the shell terminal.

I want to able to get the env varibles in my wp-config. I am using getenv but it is not working..

Any suggestions..

Thanks

Both previous answers, I could already pass the env variables to my apache environment served by docker. I just needed to add Pass env_name to the .htaccess file for each env variable.

I could then get the values via the $SERVER['env_name'] within my php application..

You use .env file, so you certainly use docker-compose. If not use docker-compose, .env will not make effect. And the .env file must be placed in the directory where docker-compose is run from.

Whole solution could be something like:

.env

MY_VARIABLE=abc

docker-compose.yml

version: '3'
services:
  my_service:
    environment:
      - MY_VARIABLE="${MY_VARIABLE}"

wp-config.php

echo getenv('MY_VARIABLE');

I guess you did not get env because you did not do - MY_VARIABLE="${MY_VARIABLE}" in docker-compose.yml, the value in .env will not be automatically act as an environment variable to container, you need to handle it in compose file. FYI.

Detail refers to offical guide

You can set the environment variable for your docker container in 2 ways

  1. In docker run command use docker run -e VARIABLE=VALUE ...

  2. In docker-compose file you can set in like:

      environment:
    - DEBUG=1
