Description
I'm getting the error "To fix it set server name by environment variable PHP_IDE_CONFIG and restart debug session." in the debug window of phpstorm. Docker-Compose setup or the guide seems to be missing something to successfully accept incoming remote debugging connections.

Steps To Reproduce

Expected Result
Xdebug should stop at the breakpoint of src/pub/index.php . e.g. at $bootstrap->run($app); .

Actual Result

Window pops up when loading the homepage of magento2.test. None of the fields are editable. Trying different options here does not seem to work.

Then, this error

I added a env variable, PHP_IDE_CONFIG=serverName=magento2.test to phpfpm , and that seems to have resolved the issue. I had tried to add it to the nginx container (doh), and obviously, that wasn't right.

Off topic, but I also set max_allowed_packet=64M to allow the Magento data migration tool to run. The default setting wasn't sufficient.

Hi @younkim . I apologize for not replying, I have been on vacation for a while. The PHP_IDE_CONFIG var should not need to be set for Xdebug to work. I have tested this many times and it all works out of the box as long as the other config is setup in PHPStorm.

As far as max_allowed_packets , I have reopened this ticket about this. I have noticed this a long time ago. I will make an update so that this config is set out of the box so we don't need to make this change. All of the built-in Magento code should be able to be worked with out of the box instead of needing to make one-off config changes 😄

Before:

MySQL [magento]> SHOW VARIABLES like '%max_allowed_packet%';
+--------------------------+------------+
| Variable_name            | Value      |
+--------------------------+------------+
| max_allowed_packet       | 4194304    |
After:
MySQL [magento]> SHOW VARIABLES like '%max_allowed_packet%';
+--------------------------+------------+
| Variable_name            | Value      |
+--------------------------+------------+
| max_allowed_packet       | 134217728  |

have the same problem. Unfortunately, it does not still work for me too, even with PHP_IDE_CONFIG. How did you do that? just export PHP_IDE_CONFIG=serverName=magento2.test?
UPDATE:

i solved that by adding environment for PHP_IDE_CONFIG into  docker config:
    image: markoshust/magento-php:7.4-fpm-0
    links:
    volumes: *appvolumes
    environment:
      - PHP_IDE_CONFIG=serverName=magento2.test
