Redmine

Hello,

I am currently facing issues trying to recover my Redmine.
I used to have 2 Docker containers, one for the database and one for redmine itself:

docker run -d --restart=always --name redmine-db -e MYSQL_ROOT_PASSWORD=SECRET -e MYSQL_DATABASE=redmine mysql:5.6.27
docker run -d --restart=always --name redmine-cuckoo --link redmine-db:mysql -p 8000:3000 redmine:5.0.4

I have the 3 different backup files: one for the database, one for files and one for config:

docker run --rm --volumes-from redmine-db -v $(pwd):/backup mysql tar cvfz /backup/redmine-db.tar.gz /var/lib/mysql/redmine
docker run --rm --volumes-from redmine-cuckoo -v $(pwd):/backup redmine:3.2.1 tar cvfz\
 /backup/redmine-files.tar.gz /usr/src/redmine/files
docker run --rm --volumes-from redmine-cuckoo -v $(pwd):/backup redmine:3.2.1 tar cvfz\
 /backup/redmine-config.tar.gz /usr/src/redmine/config

I think the issue is with the database recovery. I created a new redmine-db container (as above - with mysql root password), then I copied back my redmine-db.tar.gz in the container and untarred it.

In redmine-db container, there is however something not normal. I have plenty of tables (good), but I can't access them!?

mysql> show tables;

mysql> select * from users;
ERROR 1146 (42S02): Table 'redmine.users' doesn't exist

Should I have backuped something else in redmine-db.tar.gz? Is there a way to recover nonetheless?

From this link: https://stackoverflow.com/questions/7759170/mysql-table-doesnt-exist-but-it-does-or-it-should, it looks like I should have backuped ib* files in the root of the MySQL datadir (I did not, did not know).
Is there a way to restore however? I suspect not.
If I can't recover the database, will the config and files directory contain anything interesting I can recover? I wanted to recover the contents of each tasks (label, description etc).

Thanks,
