While running "sudo docker-compose -f docker-compose.prod.yml up", I had the following error :

Anyone had this issue, how could I solve this? Thanks !

@AchrafB2015 The backend cannot connect to the MySQL server that docker spawned. If you could share the docker-compose file used and the output of docker ps -a or docker-compose ps -a, it would help me debug the issue.

@manrajgrover I have the same issue. I just used the docker-compose.prod.yml from main, but changed the passwords from the defaults.

Here is my output:

@manrajgrover I also tried again using the default passwords (i.e. not changing the docker-compose.prod.yml from main) and am still getting this issue.

My base system is ubuntu-22.04

It does appear to work with the dev docker, I can at least get to the landing page.

@turian Hi, can you try connecting to MySQL through docker container created?

Using credentials mentioned here

$ docker exec -it audino-mysql-1 /bin/bash
$ mysql -u audino -p -A -P 3306

@manrajgrover So trying those commands using the default credentials, I cannot connect:

joseph@audino:/root$ docker exec -it audino-mysql-1 /bin/bash
bash-4.2# mysql -u audino -p -A -P 3306
Enter password:
ERROR 1045 (28000): Access denied for user 'audino'@'localhost' (using password: YES)
