Then open the ``.env`` file to setup the mail server. Modify the ``ROOT`` setting
to match your setup directory if different from ``/mailu``.
Important configuration variables
---------------------------------
Modify the ``VERSION`` configuration in the ``.env`` file to reflect the version you picked.
Open the ``.env`` file and review the following variable settings:
Set the common configuration values
-----------------------------------
- Change ``ROOT`` if you have your setup directory in a different location then ``/mailu``.
- Check ``VERSION`` to reflect the version you picked. (``master`` or ``1.5``).
Open the ``.env`` file and set configuration settings after reading the configuration
documentation. Some settings are specific to the Docker Compose setup.
Make sure to read the comments in the file and instructions from the :ref:`common_cfg` section.
Modify ``BIND_ADDRESS4`` to match the public IP address assigned to your server.
This address should be configured on one of the network interfaces of the server.
If the address is not configured directly (NAT) on any of the network interfaces or if
you would simply like the server to listen on all interfaces, use ``0.0.0.0``.
Modify ``BIND_ADDRESS6`` to match the public IPv6 address assigned to your server.
The behavior is identical to ``BIND_ADDRESS4``.
TLS certificates
````````````````
Set the ``TLS_FLAVOR`` to one of the following
values:
- ``cert`` is the default and requires certificates to be setup manually;
- ``letsencrypt`` will use the Letsencrypt! CA to generate automatic ceriticates;
- ``letsencrypt`` will use the *Letsencrypt!* CA to generate automatic ceriticates;
- ``mail`` is similar to ``cert`` except that TLS will only be served for
emails (IMAP and SMTP), not HTTP (use it behind reverse proxies);
- ``mail-letsencrypt`` is similar to ``letsencrypt`` except that TLS will only be served for
emails (IMAP and SMTP), not HTTP (use it behind reverse proxies);
- ``notls`` will disable TLS, this is not recommended except for testing.
.. note::
When using *Letsencrypt!* you have to make sure that the DNS ``A`` and ``AAAA`` records for the
all hostnames mentioned in the ``HOSTNAMES`` variable match with the ip adresses of you server.
Or else certificate generation will fail! See also: :ref:`dns_setup`.
Bind address
````````````
Modify ``BIND_ADDRESS4`` and ``BIND_ADDRESS6`` to match the public IP addresses assigned to your server. For IPv6 you will need the ``<global>`` scope address.
You can find those addresses by running the following:
.. code-block:: bash
[root@mailu ~]$ ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

If the address is not configured directly (NAT) on any of the network interfaces or if
you would simply like the server to listen on all interfaces, use ``0.0.0.0`` and ``::``. Note that running is this mode is not supported and can lead to `issues`_.

We supply a separate ``test/build.yml`` file for
convenience. To build all Mailu containers:
.. code-block:: bash
docker-compose build admin webdav
docker-compose -f tests/build.yml build
Then you can simply start the stack as normal, newly-built images will be used.
The ``build.yml`` file has two variables:
#. ``$DOCKER_ORG``: First part of the image tag. Defaults to *mailu* and needs to be changed
only when pushing to your own Docker hub account.
#. ``$VERSION``: Last part of the image tag. Defaults to *local* to differentiate from pulled
images.
To re-build only specific containers at a later time.
.. code-block:: bash
docker-compose -f tests/build.yml build admin webdav
If you have to push the images to Docker Hub for testing in Docker Swarm or a remote
host, you have to define ``DOCKER_ORG`` (usually your Docker user-name) and login to
the hub.
.. code-block:: bash
docker login

export VERSION="feat-extra-app"

To run the newly created images: ``cd`` to your project directory. Edit ``.env`` to set
``VERSION`` to the same value as used during the build, which defaults to ``local``.

# Install Mailu on a docker swarm
## Prequisites
### Swarm
In order to deploy Mailu on a swarm, you will first need to initialize the swarm:
The main command will be:
```bash
docker swarm init --advertise-addr <IP_ADDR>
```
See https://docs.docker.com/engine/swarm/swarm-tutorial/create-swarm/
If you want to add other managers or workers, please use:
```bash
docker swarm join --token xxxxx
```
See https://docs.docker.com/engine/swarm/join-nodes/
You have now a working swarm, and you can check its status with:
```bash
core@coreos-01 ~/git/Mailu/docs/swarm/1.5 $ docker node ls
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS ENGINE VERSION
xhgeekkrlttpmtgmapt5hyxrb black-pearl Ready Active 18.06.0-ce
sczlqjgfhehsfdjhfhhph1nvb * coreos-01 Ready Active Leader 18.03.1-ce
mzrm9nbdggsfz4sgq6dhs5i6n flying-dutchman Ready Active 18.06.0-ce
```
### Volume definition
For data persistance (the Mailu services might be launched/relaunched on any of the swarm nodes), we need to have Mailu data stored in a manner accessible by every manager or worker in the swarm.
Hereafter we will assume that "Mailu Data" is available on every node at "$ROOT/certs:/certs" (GlusterFS and nfs shares have been successfully used).
On this example, we are using:
- the mesh routing mode (default mode). With this mode, each service is given a virtual IP adress and docker manages the routing between this virtual IP and the container(s) providing this service.
- the default ingress mode.
### Allow authentification with the mesh routing
In order to allow every (front & webmail) container to access the other services, we will use the variable POD_ADDRESS_RANGE.
Let's create the mailu_default network:
```bash
core@coreos-01 ~ $ docker network create -d overlay --attachable mailu_default
core@coreos-01 ~ $ docker network inspect mailu_default | grep Subnet
"Subnet": "10.0.1.0/24",
```
In the docker-compose.yml file, we will then use POD_ADDRESS_RANGE = 10.0.1.0/24
In fact, imap & smtp logs doesn't show the IPs from the front(s) container(s), but the IP of "mailu_default-endpoint". So it is sufficient to set POD_ADDRESS_RANGE to this specific ip (which can be found by inspecting mailu_default network). The issue is that this endpoint is created while the stack is created, I did'nt figure a way to determine this IP before the stack creation...
### Limitation with the ingress mode
With the default ingress mode, the front(s) container(s) will see origin IP(s) all being 10.255.0.x (which is the ingress-endpoint, can be found by inspecting the ingress network)
This issue is known and discussed here:
https://github.com/moby/moby/issues/25526
A workaround (using network host mode and global deployment) is discussed here:
https://github.com/moby/moby/issues/25526#issuecomment-336363408
### Don't create an open relay !
As a side effect of this ingress mode "feature", make sure that the ingress subnet is not in your RELAYHOST, otherwise you would create an smtp open relay :-(
## Scalability
- smtp and imap are scalable
- front and webmail are scalable (pending POD_ADDRESS_RANGE is used), although the let's encrypt magic might not like it (race condidtion ? or risk to be banned by let's encrypt server if too many front containers attemps to renew the certs at the same time)
- redis, antispam, antivirus, fetchmail, admin, webdav have not been tested (hence replicas=1 in the following docker-compose.yml file)
## Variable substitution and docker-compose.yml
The docker stack deploy command doesn't support variable substitution in the .yml file itself.
As a consequence, we cannot simply use ``` docker stack deploy -c docker.compose.yml mailu ```
Instead, we will use the following work-around:
``` echo "$(docker-compose -f /mnt/docker/apps/mailu/docker-compose.yml config 2>/dev/null)" | docker stack deploy -c- mailu ```
We need also to:
- add a deploy section for every service
- modify the way the ports are defined for the front service
- add the POD_ADDRESS_RANGE definition for imap, smtp and antispam services

```
See how the services are being deployed:
```bash
core@coreos-01 ~ $ docker service ls
ID NAME MODE REPLICAS IMAGE PORTS
ywnsetmtkb1l mailu_antivirus replicated 1/1 mailu/none:master
pqokiaz0q128 mailu_fetchmail replicated 1/1 mailu/fetchmail:master
```
check a specific service:
```bash
core@coreos-01 ~ $ docker service ps mailu_fetchmail
ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS
tbu8ppgsdffj mailu_fetchmail.1 mailu/fetchmail:master coreos-01 Running Running 11 days ago
```
You might also have a look on the logs:
```bash
core@coreos-01 ~ $ docker service logs -f mailu_fetchmail
```
## Remove the stack
Run the follwoing command:
```bash
core@coreos-01 ~ $ docker stack rm mailu

For data persistance (the Mailu services might be launched/relaunched on any of the swarm nodes), we need to have Mailu data stored in a manner accessible by every manager or worker in the swarm.
Hereafter we will use a NFS share:
```bash
core@coreos-01 ~ $ showmount -e 192.168.0.30
Export list for 192.168.0.30:
/mnt/Pool1/pv 192.168.0.0
```
on the nfs server, I am using the following /etc/exports
```bash
$more /etc/exports
/mnt/Pool1/pv -alldirs -mapall=root -network 192.168.0.0 -mask 255.255.255.0
```
on the nfs server, I created the Mailu directory (in fact I copied a working Mailu set-up)
```bash
$mkdir /mnt/Pool1/pv/mailu
```
On your manager node, mount the nfs share to check that the share is available:
```bash
core@coreos-01 ~ $ sudo mount -t nfs 192.168.0.30:/mnt/Pool1/pv/mailu /mnt/local/
```
If this is ok, you can umount it:
```bash
core@coreos-01 ~ $ sudo umount /mnt/local/
```
## Networking mode
On this example, we are using:
- the mesh routing mode (default mode). With this mode, each service is given a virtual IP adress and docker manages the routing between this virtual IP and the container(s) providing this service.
- the default ingress mode.
### Allow authentification with the mesh routing
In order to allow every (front & webmail) container to access the other services, we will use the variable POD_ADDRESS_RANGE.
Let's create the mailu_default network:
```bash
core@coreos-01 ~ $ docker network create -d overlay --attachable mailu_default
core@coreos-01 ~ $ docker network inspect mailu_default | grep Subnet
"Subnet": "10.0.1.0/24",
```
In the docker-compose.yml file, we will then use POD_ADDRESS_RANGE = 10.0.1.0/24
In fact, imap & smtp logs doesn't show the IPs from the front(s) container(s), but the IP of "mailu_default-endpoint". So it is sufficient to set POD_ADDRESS_RANGE to this specific ip (which can be found by inspecting mailu_default network). The issue is that this endpoint is created while the stack is created, I did'nt figure a way to determine this IP before the stack creation...
### Limitation with the ingress mode
With the default ingress mode, the front(s) container(s) will see origin IP(s) all being 10.255.0.x (which is the ingress-endpoint, can be found by inspecting the ingress network)
This issue is known and discussed here:
https://github.com/moby/moby/issues/25526
A workaround (using network host mode and global deployment) is discussed here:
https://github.com/moby/moby/issues/25526#issuecomment-336363408
### Don't create an open relay !
As a side effect of this ingress mode "feature", make sure that the ingress subnet is not in your RELAYHOST, otherwise you would create an smtp open relay :-(
## Scalability
- smtp and imap are scalable
- front and webmail are scalable (pending POD_ADDRESS_RANGE is used), although the let's encrypt magic might not like it (race condidtion ? or risk to be banned by let's encrypt server if too many front containers attemps to renew the certs at the same time)
- redis, antispam, antivirus, fetchmail, admin, webdav have not been tested (hence replicas=1 in the following docker-compose.yml file)
## Variable substitution and docker-compose.yml
The docker stack deploy command doesn't support variable substitution in the .yml file itself. As a consequence, we need to use the following work-around:
``` echo "$(docker-compose -f /mnt/docker/apps/mailu/docker-compose.yml config 2>/dev/null)" | docker stack deploy -c- mailu ```
We need also to:
- change the way we define the volumes (nfs share in our case)
- add a deploy section for every service
- the way the ports are defined for the front service
## Docker compose
An example of docker-compose-stack.yml file is available here:

## Deploy Mailu on the docker swarm
Run the following command:
```bash
echo "$(docker-compose -f /mnt/docker/apps/mailu/docker-compose.yml config 2>/dev/null)" | docker stack deploy -c- mailu
```
See how the services are being deployed:
```bash
core@coreos-01 ~ $ docker service ls
ID NAME MODE REPLICAS IMAGE PORTS
ywnsetmtkb1l mailu_antivirus replicated 1/1 mailu/none:master
pqokiaz0q128 mailu_fetchmail replicated 1/1 mailu/fetchmail:master
```
check a specific service:
```bash
core@coreos-01 ~ $ docker service ps mailu_fetchmail
ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS
tbu8ppgsdffj mailu_fetchmail.1 mailu/fetchmail:master coreos-01 Running Running 11 days ago
```
## Remove the stack
Run the follwoing command:
```bash
core@coreos-01 ~ $ docker stack rm mailu
```
