# Install Mailu on a docker swarm
|
||||
|
||||
## Prerequisites
|
||||
|
||||
### 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 persistence (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 a swarm, the services are available (default mode) through a routing mesh managed by docker itself. With this mode, each service is given a virtual IP adress and docker manages the routing between this virtual IP and the container(s) provinding this service.
|
||||
With this default networking mode, I cannot get login working properly... As found in https://github.com/Mailu/Mailu/issues/375 , a workaround is to use the dnsrr networking mode at least for the front services.
|
||||
|
||||
The main consequence/limitation will be that the front services will *not* be available on every node, but only on the node where it will be deployed. In my case, I have only one manager and I choose to deploy the front service to the manager node, so I know on wich IP the front service will be available (aka the IP adress of my manager node).
|
||||
|
||||
### Variable substitution and docker-compose.yml
|
||||
The docker stack deploy command doesn't support variable substitution in the .yml file itself (but we still can use .env file to pass variables to the services). As a consequence we need to adjust the docker-compose file in order to :
|
||||
- remove all variables : $VERSION , $BIND_ADDRESS4 , $BIND_ADDRESS6 , $ANTIVIRUS , $WEBMAIL , etc
|
||||
- change the way we define the volumes (nfs share in our case)
|
||||
- add a deploy section for every 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
|
||||
docker stack deploy -c docker-compose-stack.yml 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:1.5
|
||||
pqokiaz0q128 mailu_fetchmail replicated 1/1 mailu/fetchmail:1.5
|
||||
```
|
||||
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:1.5 coreos-01 Running Running 11 days ago
|
||||
```
|
||||
|
||||
### Remove the stack
|
||||
Run the following command:
|
||||
```bash
|
||||
core@coreos-01 ~ $ docker stack rm mailu

# Install Mailu on a docker swarm
|
||||
|
||||
## Some warnings
|
||||
|
||||
### How Docker swarm works
|
||||
|
||||
Docker swarm enables replication and fail-over scenarios. As a feature, if a node dies or goes away, Docker will re-schedule it's containers on the remaining nodes.
|
||||
In order to take this decisions, docker swarm works on a consensus between managers regarding the state of nodes. Therefore it recommends to always have an uneven amount of manager nodes. This will always give a majority on either halve of a potential network split.
|
||||
|
||||
### Storage
|
||||
|
||||
On top of this some of Mailu's containers heavily rely on disk storage. As noted below, every host will need the same dataset on every host where related containers are run. So Dovecot IMAP needs `/mailu/mail` replicated to every node it *may* be scheduled to run. There are various solutions for this like NFS and GlusterFS.
|
||||
|
||||
### When disaster strikes
|
||||
|
||||
So imagine 3 swarm nodes and 3 GlusterFS endpoints:
|
||||
|
||||
```
|
||||
node-A -> gluster-A --|
|
||||
node-B -> gluster-B --|--> Single file system
|
||||
node-C -> gluster-C --|
|
||||
```
|
||||
|
||||
Each node has a connection to the shared file system and maintains connections between the other nodes. Let's say Dovecot is running on `node-A`. Now a network error / outage occurs on the route between `node-A` and the remaining nodes, but stays connected to the `gluster-A` endpoint. `node-B` and `node-C` conclude that `node-A` is down. They reschedule Dovecot to start on either one of them. Dovecot starts reading and writing its indexes to the **shared** filesystem. However, it is possible the Dovecot on `node-A` is still up and handling some client requests. I've seen cases where this situations resulted in:
|
||||
|
||||
- Retained locks
|
||||
- Corrupted indexes
|
||||
- Users no longer able to read any of mail
|
||||
- Lost mail
|
||||
|
||||
### It gets funkier
|
||||
|
||||
Our original deployment also included `main.db` on the GlusterFS. Due to the above we corrupted it once and we decided to move it to local storage and restirct the `admin` container to that host only. This inspired us to put some legwork is supporting different database back-ends like MySQL and PostgreSQL. We highly recommend to use either of them, in favor of sqlite.
|
||||
|
||||
### Conclusion
|
||||
|
||||
Although the above situation is less-likely to occur on a stable (local) network, it does indicate a failure case where there is a probability of data-loss or downtime. It may help to create redundant networks, but the effort might be too much for the actual results. We will need to look into better and safer methods of replicating mail data. For now, we regret to have to inform you that Docker swarm deployment is **unstable** and should be avoided in production environments.

## Prerequisites
|
||||
|
||||
### 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 persistence (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" (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 SUBNET.
|
||||
|
||||
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 SUBNET = 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 SUBNET 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:

### 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 :-(
|
||||
|
||||
### Ratelimits
|
||||
|
||||
When using ingress mode you probably want to disable rate limits, because all requests originate from the same ip address. Otherwise automatic login attempts can easily DoS the legitimate users.
|
||||
|
||||
## Scalability
|
||||
- smtp and imap are scalable
|
||||
- front and webmail are scalable (pending SUBNET 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)
|
||||
|
||||
## Docker secrets
|
||||
There are DB_PW_FILE and SECRET_KEY_FILE environment variables available to specify files for these variables. These can be used to configure Docker secrets instead of writing the values directly into the `docker-compose.yml` or `mailu.env`.
|
||||
|
||||
## 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 SUBNET definition for admin (for imap), smtp and antispam services
|
||||
|
||||

## 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
|
||||
```
|
||||
You might also have a look on the logs:
|
||||
```bash
|
||||
core@coreos-01 ~ $ docker service logs -f mailu_fetchmail
|
||||
```
|
||||
|
||||
## Remove the stack
|
||||
Run the following command:
|
||||
```bash
|
||||
core@coreos-01 ~ $ docker stack rm mailu
|
||||
```
|
||||
|
||||
## Notes on unbound resolver
|
||||
|
||||
In Docker compose flavor we currently have the option to include the unbound DNS resolver. This does not work in Docker Swarm, as it in not possible to configure any static IP addresses. There is an [open issue](https://github.com/moby/moby/issues/24170) for this at Docker. However, this doesn't seem to move anywhere since some time now. For that reasons we've chosen not to include the unbound resolver in the stack flavor.
|
||||
|
||||
If you still want to benefit from Unbound as a system resolver, you can install it system-wide. The following procedure was done on a Fedora 28 system and might needs some adjustments for your system. Note that this will need to be done on every swarm node. In this example we will make use of `dnssec-trigger`, which is used to configure unbound. When installing this and running the service, unbound is pulled in as dependency and does not need to be installed, configured or run separately.
|
||||
|
||||
Install required packages(unbound will be installed as dependency):
|
||||
|
||||
```
|
||||
sudo dnf install dnssec-trigger
|
||||
```
|
||||
|
||||
Enable and start the *dnssec-trigger* daemon:
|
||||
|
||||
```
|
||||
sudo systemctl enable --now dnssec-triggerd.service
|
||||
```
|
||||
|
||||
Configure NetworkManager to use unbound, create the file `/etc/NetworkManager/conf.d/unbound.conf` with contents:
|
||||
|
||||
```
|
||||
[main]
|
||||
dns=unbound
|
||||
```
|
||||
|
||||
You might need to restart NetworkManager for the changes to take effect:
|
||||
|
||||
```
|
||||
sudo systemctl restart NetworkManager
|
||||
```
|
||||
|
||||
Verify `resolv.conf`:
|
||||
|
||||
```
|
||||
$ cat /etc/resolv.conf
|
||||
# Generated by dnssec-trigger-script
|
||||
nameserver 127.0.0.1
|
||||
```
|
||||
|
||||

# 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 persistence (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 address 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 SUBNET.
|
||||
|
||||
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 SUBNET = 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 SUBNET 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 SUBNET 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
|
||||
|
||||

## 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:

<p>To deploy the docker stack use the following commands. For more information about setting up docker swarm nodes read the
|

<a href="https://docs.docker.com/get-started">docker documentation</a></p>
|
||||
|
||||
<pre><code>cd {{ root }}

docker swarm init

docker stack deploy -c docker-compose.yml mailu
|
||||
</pre></code>
|
||||
|
||||
In the docker stack deploy command, mailu is the app name. Feel free to change it.<br/>
|
||||
In order to display the running container you can use<br/>
|
||||
<pre><code>docker ps</code></pre>
|
||||
or
|
||||
<pre><code>docker stack ps --no-trunc mailu</code></pre>
|
||||
Command for removing docker stack is
|
||||
<pre><code>docker stack rm mailu</code></pre>
|
||||
|
||||
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:
|
||||
|
||||
<pre><code>docker exec $(docker ps | grep admin | cut -d ' ' -f1) flask mailu admin {{ postmaster }} {{ domain }} PASSWORD
|
||||
</pre></code>
|
||||
|
||||
<p>Login to the admin interface to change the password for a safe one, at
|
||||
{% if admin_enabled %}
|
||||
one of the hostnames
|
||||
<a href="https://{{ hostnames.split(',')[0] }}{{ admin_path }}">{{ hostnames.split(',')[0] }}{{ admin_path }}</a>.
|
||||
{% else %}
|
||||
<a href="http://127.0.0.1:8080/ui">http://127.0.0.1:8080/ui</a> (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
|
||||
<pre><code>ssh -L 127.0.0.1:8080:127.0.0.1:8080 <user>@<server>
|
||||
</code></pre>
|
||||
And access the above URL from your local machine.
|
||||
<br />
