Docker Stack expects a project file, named docker-compose.yml in a project directory. First create your project directory.

mkdir -p {{ root }}/{redis,certs,data,dkim,mail,mailqueue,overrides/rspamd,overrides/postfix,overrides/dovecot,overrides/nginx,filter,dav,webmail}

Then download the project file. A side configuration file makes it easier to read and check the configuration variables generated by the wizard.

cd {{ root }}
wget {{ url_for('.file', uid=uid, _scheme='https', filepath='docker-compose.yml', _external=True) }}
wget {{ url_for('.file', uid=uid, _scheme='https', filepath='mailu.env', _external=True) }}
{% endcall %} {% call macros.panel("info", "Step 2 - Review the configuration") %}

We did not insert any malicious code on purpose in the configurations we distribute, but your download could have been intercepted, or our wizard website could have been compromised, so make sure you check the configuration files before going any further.

When you are done checking them, check them one last time.

{% endcall %} {% call macros.panel("info", "Step 3 - Deploy docker stack") %}

To deploy the docker stack use the following commands. For more information about setting up docker swarm nodes read the docker documentation

cd {{ root }}
docker swarm init
docker stack deploy -c docker-compose.yml mailu
In the docker stack deploy command, mailu is the app name. Feel free to change it.
In order to display the running container you can use
docker ps
or
docker stack ps --no-trunc mailu
Command for removing docker stack is
docker stack rm mailu
Before you can use Mailu, you must create the primary administrator user account. This should be {{ postmaster }}@{{ domain }}. Use the following command, changing PASSWORD to your liking:
docker exec $(docker ps | grep admin | cut -d ' ' -f1) flask mailu admin {{ postmaster }} {{ domain }} PASSWORD

Login to the admin interface to change the password for a safe one, at {% if admin_enabled %} one of the hostnames {{ hostnames.split(',')[0] }}{{ admin_path }}. {% else %} http://127.0.0.1:8080/ui (only directly from the host running docker). If you run mailu on a remote server, and wish to access the admin interface via a SSH tunnel, you can create a port-forward from your local machine to your server like

ssh -L 127.0.0.1:8080:127.0.0.1:8080 <user>@<server>
And access the above URL from your local machine.
{% endif %} Also, choose the "Update password" option in the left menu.
