Docker PhpMyAdmin configuration to access Joomla (local) Windows 10

Question

My PHP is found at: http://localhost:8080/administrator/index.php
And my PHPMyAdmin is found at: http://localhost:8080/phpmyadmin/index.php?route=/

I encounter an error when trying to log into PhpMyAdmin:

mysqli::real_connect(): (HY000/2002): No such file or directory

I have a local Docker Compose app running:

version: '3.1'

services:
  joomla:
    image: joomla
    restart: always
    links:
      - joomladb:mysql
    ports:
      - 8080:80
    volumes:
      - "../:/var/www/html"
    environment:
      JOOMLA_DB_HOST: joomladb
      JOOMLA_DB_PASSWORD: root

  joomladb:
    image: mysql:5.6
    ports:
      - 3306
    restart: always
    volumes:
      - "./data:/var/lib/mysql"
    environment:
      MYSQL_ROOT_PASSWORD: root

I go to that route via my console, and execute the command docker-compose up, that way when i list my docker images i get as follows:

C:\Users\user/docker ps
CONTAINER ID  IMAGE     COMMAND                   CREATED       STATUS        PORTS                   NAMES
aaca47f88000  joomla    "/entrypoint.sh apac..."  2 hours ago   Up 11 minutes 0.0.0.0:8080- >80/tcp   ops_joomla_1
B8d265boбa86  mysql:5.6 "docker-entrypoint....."  19 hours ago  Up 11 minutes 0.0.0.0:55738->3306/tcp ops_joomladb_1

I have checked my MySQL image and that works correctly.

Joomla works correctly as I can log in and navigate without encountering any problems. I havent changed any PhpMyAdmin credentials in any PHP files so it should be default, as far as I am aware that is:

username: root
pawword: ``.

Here is my config.inic.php file:

<?php

I allowed logging in using no password by changing $cfg['Servers'][$i]['AllowNoPassword'] from false to true.

And since I couldn't change the permissions to the file, I added the following line to the file:

$cfg['CheckConfigurationPermissions'] = false;

I also added a random blowfish as my auth mode is cookie

$cfg['blowfish_secret'] = 'W-Bo3r6x3vm-LM{fv/=uR/=2ASEHa[dP';

I have read on other sites that the error I am getting can be fixed by changing $cfg['Servers'][$i]['host'] from 'localhost' to '127.0.0.1'. However, I want to connect by typing in "localhost" and not the IP, and it gives an other error:

mysqli::real_connect(): (HY000/2002): Connection refused

I don't think I have any dockerfiles, if I did where would I find them?

Does anyone know how to fix this problem?

I appreciate the help, thanks!

PS: If any more information is needed I'd be happy to edit the post and add it

we need the docker compose yaml and any relevent dockerfiles — delboy1978uk, Apr 13 '21 at 14:51
I don't know Joomla, does it come with PhpMyAdmin or are you using a PhpMyAdmin instance outside the Docker stack ? You mentionned you wanted to access to the database with `localhost` but your containers have their own IP in the Docker network. Maybe you just need to use the service name: `joomladb`. Tell me if it works and I'll post a detailed answer. — AymDev, Apr 13 '21 at 15:17
If you use an external PhpMyAdmin I think you will need to map the port of the MySQL container. In your **docker-compose.yml**, in `services.joomladb.ports`, replace `3306` with `3306:3306`. As you can see in the `docker ps` output, the port of your machine mapped to container's `3306` is `55738` (Docker probably chose it randomly). — AymDev, Apr 13 '21 at 16:00
@AymDev Sorry for the late reply. I downloaded the php zip file from the official site and extracted it into my Joomla folder, that way i could acces it with [localhost](http://localhost:8080/phpmyadmin/index.php?route=/) , I also cannot log in with `joomladb` as the username. I also added `3306:3306` as the ports as you indicated and the docker images now have `3306` both internally and externaly, but I'm still gettign the same error — FlawFull, Apr 14 '21 at 12:26
I said to use `joomladb` instead of `localhost`, so as the host, not the username. I guess your username is `root` for a local PhpMyAdmin instance. — AymDev, Apr 14 '21 at 12:35
@AymDev If I try to use joomladb as the host it gives me the following `DNS_PROBE_FINISHED_NXDOMAIN` — FlawFull, Apr 14 '21 at 12:44
Ok so I guess it answers my first question: you don't use PhpMyAdmin inside a container. I'm afraid you're in the special case I still don't explain where `127.0.0.1` works while `localhost` doesn't. Try with that, just to see if it works. — AymDev, Apr 14 '21 at 12:51
@AymDev Using localhost i get `mysqli::real_connect(): (HY000/2002): No such file or directory` and using 127.0.0.1 i get `mysqli::real_connect(): (HY000/2002): Connection refused` — FlawFull, Apr 14 '21 at 13:29
I think you should stick to `127.0.0.1` for now (it's the same as `localhost` so no worries). I'd suspect something related to the database name. Try to see if [this question](https://stackoverflow.com/questions/40561433/docker-mysql-2002-connection-refused) helps. — AymDev, Apr 14 '21 at 13:35
I just remembered I saved a [gist](https://gist.github.com/AymDev/f1376783f60a416b9402a5e8ef39e784) with a Docker Compose file for MySQL + PhpMyAdmin. Worked very well for a long time. Maybe you'll have a use for it. — AymDev, Apr 14 '21 at 13:41
If you are diibg Joomla development, please join [joomla.se] Stack Exchange and ask your Joomla questions there to reach an audience of people with an intimate understanding of the CMS and its extensions. — mickmackusa, May 04 '21 at 21:13
