RT4 make initdb uses wrong IP address of mysql and fails due to this


I am trying to install RT4 using Docker and “make initdb” falis. I have set the the following ./configure parameter
–with-db-rt-pass=$DB_PASS \

as you can see the db-host is set to When the "make initdb"command is run, it fails wiht the following message

root@b1f514f430f4:/usr/local/src/rt-4.4.2# make initdb
/usr/bin/perl -I/opt/rt4/local/lib -I/opt/rt4/lib sbin/rt-setup-database --action init --prompt-for-dba-password
In order to create or update your RT database, this script needs to connect to your  mysql instance on (port '3306') as root
Please specify that user's database password below. If the user has no database
password, just press return.

As you can see it uses ‘root’@‘’ instead of ‘root’@‘’ and it does not use the password provided

any idea, what i am doing wrong?


No. RT is using the right IP. The message Access denied for user ‘root’@‘’ (using password: NO) is returned by the mysql server. It means that from (which seems to be the container where you are installing RT) you are trying to log in as root.

Note that in mysql you may have several root users depending on the connecting host (which may contain wildcards, too).
