Documentation for installing iRedMail with external mysql server is here: https://docs.iredmail.org/install.iredmail.with.remote.mysql.server.html

I would suggest creating a second Docker image for this purpose, even if most of the files can be shared.

As an insider, extra image is not necessary. The only trick is to trick startup scripts. Startup scripts overwrite "default" values of passwords by values from /opt/iredmail/.cv... For external mysql server config-get needs to be modified as well, and thoroughly tested..

I am very bad with time now, so I am looking forward to receive a pull-request.. Thank you

I have an apparently working solution to this but need to do a bit more testing before I submit a pull request. It involves patching the relevant config files during the initial boot. So far this is working well with an external MariaDB container, but should work with MySql as well.

Perfect, I am just updating for the latest version of iredmail.. maybe we can release it together :-) I would test your setup with updates of the database which takes place at every release...

[toastbrotch]

looking forward to the pull request. i think it should not take care where the db actually is, this is the responsibility of the user that wants to run the container with an external db. i just need a way to define my own db.

does it actually work by setting all those env-vars here https://docs.iredmail.org/install.iredmail.with.remote.mysql.server.html#install-iredmail

I have just rewrite the starting mechanism due to phusion image got terribly old. The container is migrated to centos:7 base image, and supervisord is used for dealing with services.

Mysql was upgraded to MariaDB which is just a minor update. Importantly, all database preparation is in mariadb-server service which can be disabled at the startup through entrypoint.sh. Then every service will need to validated to usage of localhost.
