Database Setup issue

[ejo4041]

I am fairly new to docker, docker-compose, and piwik, but I did follow the instructions in the README to a T and I am getting this error at the Database setup page:

Error while trying to connect to the database server: SQLSTATE[HY000] [1045] Access denied for user 'root'@'172.24.0.3' (using password: YES)

The only modification I have made:

...(networks section)
-  lb_web:
-    external: true
+  #lb_web:
+    #external: true
...(web section)
+    ports:
        - 8078:80
-    - lb_web
+    #- lb_web

I believe I did the proper 'docker-compose down' and then 'MYSQL_ROOT_PASSWORD=mystrongpassword docker-compose up' after making these changes

Here the output I see from the logs:

Any suggestions? I ssh'd to the piwik DB container, but I could not login to mysql with the root user and password I used. Maybe I am doing something wrong, or some modifications need to be made to the docker container. Thanks!

Based on your presented output, "Please check that /var/www/html/config/config.ini.php is readable by the user 'www-data'" I believe that you are experiencing a user/group permission issue, and so the file cannot be read.

POSSIBLE SOLUTION:
Add yourself "$USER" to the www-data group and then adjust the file and directory permissions so that the file becomes readable.

APPROACH:
Enter the commands below into your server's CLI and then restart the server and see if it fixes your problem:

sudo gpasswd -a "$USER" www-data
sudo chown -R "$USER":www-data /var/www/html
find /var/www/html -type f -exec chmod 0660 {} \;
sudo find /var/www/html -type d -exec chmod 2770 {} \;
