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

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
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`_.

# Install Mailu master on kubernetes
## Prequisites
### Structure
There's chosen to have a double NGINX stack for Mailu, this way the main ingress can still be used to access other websites/domains on your cluster. This is the current structure:
- `NGINX Ingress controller`: Listens to the nodes ports 80 & 443 and directly forwards all TCP traffic on the E-amail ports (993,143,25,587,...). This is because this `DaemonSet` already consumes ports 80 & 443 and uses `hostNetwork: true`
- `Cert manager`: Creates automatic Lets Encrypt certificates based on an `Ingress`-objects domain name.
- `Mailu NGINX Front container`: This container receives all the mail traffic forwarded from the ingress controller. The web traffic is also forwarded based on an ingress
- `Mailu components`: All Mailu components are split into separate files to make them more
### What you need
- A working Kubernetes cluster (tested with 1.10.5)
- A working [cert-manager](https://github.com/jetstack/cert-manager) installation
- A working nginx-ingress controller needed for the lets-encrypt certificates. You can find those files in the `nginx` subfolder
#### Cert manager
The `Cert-manager` is quite easy to deploy using Helm when reading the [docs](https://cert-manager.readthedocs.io/en/latest/getting-started/2-installing.html).
After booting the `Cert-manager` you'll need a `ClusterIssuer` which takes care of all required certificates through `Ingress` items. An example:
```yaml
apiVersion: certmanager.k8s.io/v1alpha1
kind: ClusterIssuer
metadata:
name: letsencrypt-prod
spec:
acme:
email: something@example.com
http01: {}
privateKeySecretRef:
key: ""
name: letsencrypt-stage
server: https://acme-v02.api.letsencrypt.org/directory
```
## Deploying Mailu
All manifests can be found in the `mailu` subdirectory. All commands below need to be run from this subdirectory
### Personalization
- All services run in the same namespace, currently `mailu-mailserver`. So if you want to use a different one, change the `namespace` value in **every** file
- Check the `storage-class` field in the `pvc.yaml` file, you can also change the sizes to your liking. Note that you need `RWX` (read-write-many) and `RWO` (read-write-once) storageclasses.
- Check the `configmap.yaml` and adapt it to your needs. Be sure to check the kubernetes DNS values at the end (if you use a different namespace)
- Check the `ingress-ssl.yaml` and change it to the domain you want (this is for the kubernetes ingress controller, it will forward to `mailu/nginx` a.k.a. the `front` pod)
## Installation
First run the command to start Mailu:
```bash
kubectl create -f rbac.yaml
kubectl create -f configmap.yaml
kubectl create -f pvc.yaml
kubectl create -f ingress-ssl.yaml
kubectl create -f redis.yaml
kubectl create -f front.yaml
kubectl create -f webmail.yaml
kubectl create -f imap.yaml
kubectl create -f security.yaml
kubectl create -f smtp.yaml
kubectl create -f fetchmail.yaml
kubectl create -f admin.yaml
kubectl create -f webdav.yaml
```
## Create the first admin account
When the cluster is online you need to create you master user to access `https://mail.example.com/admin`.
Enter the main `admin` pod to create the root account:
```bash
kubectl -n mailu-mailserver get po
kubectl -n mailu-mailserver exec -it mailu-admin-.... /bin/sh
```
And in the pod run the following command. The command uses following entries:
- `admin` Make it an admin user
- `root` The first part of the e-mail adres (ROOT@example.com)
- `example.com` the domain appendix
- `password` the chosen password for the user
```bash
python manage.py admin root example.com password
```
Now you should be able to login on the mail account: `https://mail.example.com/admin`
## Adaptations
### Postfix
I noticed you need an override for the `postfix` server in order to be able to send mail. I noticed Google wasn't able to deliver mail to my account and it had to do with the `smtpd_authorized_xclient_hosts` value in the config file. The config can be read [here](https://github.com/hacor/Mailu/blob/master/core/postfix/conf/main.cf#L35) and is pointing to a single IP of the service. But the requests come from the host IPs (the NGINX Ingress proxy) and they don't use the service specific IP.
Enter the `postfix` pod:
```bash
kubectl -n mailu-mailserver get po
kubectl -n mailu-mailserver exec -it mailu-smtp-.... /bin/sh
```
Now you're in the pod, create an override file like so:
```bash
vi /overrides/postfix.cf
```
And give it the following contents, off course replacing `10.2.0.0/16` with the CIDR of your pod range. This way the NGINX pods can also restart and your mail server will still operate
```bash
not_needed = true
smtpd_authorized_xclient_hosts = 10.2.0.0/16
```
The first line seems stupid, but is needed because its pasted after a #, so from the second line we're really in action.
Save and close the file and exit. Now you need to delete the pod in order to recreate the config file.
```bash
kubectl -n mailu-mailserver delete po/mailu-smtp-....
```
### Dovecot
- If you are using Dovecot on a shared file system (Glusterfs, NFS,...), you need to create a special override otherwise a lot of indexing errors will occur on your Dovecot pod.
- I also higher the number of max connections per IP. Now it's limited to 10.
Enter the dovecot pod:
```bash
kubectl -n mailu-mailserver get po
kubectl -n mailu-mailserver exec -it mailu-imap-.... /bin/sh
```
Create the file `/overrides/dovecot.conf`
```bash
vi /overrides/dovecot.conf
```
And enter following contents:
```bash
mail_nfs_index = yes
mail_nfs_storage = yes
mail_fsync = always
mmap_disable = yes
mail_max_userip_connections=100
```
Save and close the file and delete the imap pod to get it recreated.
```bash
kubectl -n mailu-mailserver delete po/mailu-imap-....
```
Wait for the pod to recreate and you're online!
Happy mailing!

Install Mailu master on kubernetes
==================================
Prequisites
-----------
Structure
~~~~~~~~~
Theres chosen to have a double NGINX stack for Mailu, this way the main
ingress can still be used to access other websites/domains on your
cluster. This is the current structure:
- ``NGINX Ingress controller``: Listens to the nodes ports 80 & 443. We have chosen to have a double NGINX stack for Mailu.
- ``Cert manager``: Creates automatic Lets Encrypt certificates based on an ``Ingress``-objects domain name.
- ``Mailu NGINX Front daemonset``: This daemonset runs in parallel with the Nginx Ingress Controller and only listens on all E-mail specific ports (25, 110, 143, 587,...)
- ``Mailu components``: All Mailu components (imap, smtp, security, webmail,...) are split into separate files to make them more handy to use, you can find the ``YAML`` files in this directory
What you need
~~~~~~~~~~~~~
- A working Kubernetes cluster (tested with 1.10.5)
- A working `cert-manager`_ installation
- A working nginx-ingress controller needed for the lets-encrypt
certificates. You can find those files in the ``nginx`` subfolder
Cert manager
^^^^^^^^^^^^
The ``Cert-manager`` is quite easy to deploy using Helm when reading the
`docs`_. After booting the ``Cert-manager`` youll need a
``ClusterIssuer`` which takes care of all required certificates through
``Ingress`` items. We chose to provide a ``clusterIssuer`` so you can provide SSL certificates
for other namespaces (different websites/services), if you don't need this option, you can easily change this by
changing ``clusterIssuer`` to ``Issuer`` and adding the ``namespace: mailu-mailserver`` to the metadata.
An example of a production and a staging ``clusterIssuer``:
.. code:: yaml
# This clusterIssuer example uses the staging environment for testing first
apiVersion: certmanager.k8s.io/v1alpha1
kind: ClusterIssuer
metadata:
name: letsencrypt-stage
spec:
acme:
email: something@example.com
http01: {}
privateKeySecretRef:
name: letsencrypt-stage
server: https://acme-staging-v02.api.letsencrypt.org/directory
.. code:: yaml
# This clusterIssuer example uses the production environment
apiVersion: certmanager.k8s.io/v1alpha1
kind: ClusterIssuer
metadata:
name: letsencrypt-prod
spec:
acme:
email: something@example.com
http01: {}
privateKeySecretRef:
name: letsencrypt-prod
server: https://acme-v02.api.letsencrypt.org/directory
**IMPORTANT**: All ``*-ingress.yaml`` files use the ``letsencrypt-stage`` ``clusterIssuer``. If you are ready for production,
change this field in all ``*-ingress.yaml`` files to ``letsencrypt-prod`` or whatever name you chose for the production.
If you choose for ``Issuer`` instead of ``clusterIssuer`` you also need to change the annotation to ``certmanager.k8s.io/issuer`` instead of ``certmanager.k8s.io/cluster-issuer``
Deploying Mailu
---------------
All manifests can be found in the ``mailu`` subdirectory. All commands
below need to be run from this subdirectory
Personalization
~~~~~~~~~~~~~~~
- All services run in the same namespace, currently ``mailu-mailserver``. So if you want to use a different one, change the ``namespace`` value in **every** file
- Check the ``storage-class`` field in the ``pvc.yaml`` file, you can also change the sizes to your liking. Note that you need ``RWX`` (read-write-many) and ``RWO`` (read-write-once) storageclasses.
- Check the ``configmap.yaml`` and adapt it to your needs. Be sure to check the kubernetes DNS values at the end (if you use a different namespace)
- Check the ``*-ingress.yaml`` files and change it to the domain you want (this is for the kubernetes ingress controller to handle the admin, webmail, webdav and auth connections)
Installation
------------
Boot the Mailu components
~~~~~~~~~~~~~~~~~~~~~~~~~
To start Mailu, run the following commands from the ``docs/kubernetes/mailu`` directory
.. code-block:: bash
kubectl create -f rbac.yaml
kubectl create -f configmap.yaml
kubectl create -f pvc.yaml
kubectl create -f redis.yaml
kubectl create -f front.yaml
kubectl create -f webmail.yaml
kubectl create -f imap.yaml
kubectl create -f security.yaml
kubectl create -f smtp.yaml
kubectl create -f fetchmail.yaml
kubectl create -f admin.yaml
kubectl create -f webdav.yaml
kubectl create -f admin-ingress.yaml
kubectl create -f webdav-ingress.yaml
kubectl create -f security-ingress.yaml
kubectl create -f webmail-ingress.yaml
Create the first admin account
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
When the cluster is online you need to create you master user to access https://mail.example.com/admin
Enter the main ``admin`` pod to create the root account:
.. code-block:: bash
kubectl -n mailu-mailserver get po
kubectl -n mailu-mailserver exec -it mailu-admin-.... /bin/sh
And in the pod run the following command. The command uses following entries:
.. code-block:: bash
python manage.py admin root example.com password
- ``admin`` Make it an admin user
- ``root`` The first part of the e-mail adres (ROOT@example.com)
- ``example.com`` the domain appendix
- ``password`` the chosen password for the user
Now you should be able to login on the mail account: https://mail.example.com/admin
Adaptations
-----------
Dovecot
~~~~~~~
- If you are using Dovecot on a shared file system (Glusterfs, NFS,...), you need to create a special override otherwise a lot of indexing errors will occur on your Dovecot pod.
- I also higher the number of max connections per IP. Now it's limited to 10.
Enter the dovecot pod:
.. code:: bash
kubectl -n mailu-mailserver get po
kubectl -n mailu-mailserver exec -it mailu-imap-.... /bin/sh
Create the file ``overrides/dovecot.conf``
.. code:: bash
vi /overrides/dovecot.conf
And enter following contents:
.. code:: bash
mail_nfs_index = yes
mail_nfs_storage = yes
mail_fsync = always
mmap_disable = yes
mail_max_userip_connections=100
Save and close the file and delete the imap pod to get it recreated.
.. code:: bash
kubectl -n mailu-mailserver delete po/mailu-imap-....
Wait for the pod to recreate and you're online!
Happy mailing!
.. _here: https://github.com/hacor/Mailu/blob/master/core/postfix/conf/main.cf#L35
.. _cert-manager: https://github.com/jetstack/cert-manager
.. _docs: https://cert-manager.readthedocs.io/en/latest/getting-started/2-installing.html
Imap login fix
~~~~~~~~~~~~~~
If it seems you're not able to login using IMAP on your Mailu accounts, check the logs of the imap container to see whether it's a permissions problem on the database.
This problem can be easily fixed by running following commands:
.. code:: bash
kubectl -n mailu-mailserver exec -it maolu-imap-... /bin/sh
chmod 777 /data/main.db

Kubernetes setup
================
Please note that Kubernetes setup is not yet well supported or documented, all
tests currently run on Docker Compose. The configuration has not yet been updated
to work properly with ngin authentication proxy.
Prepare the environment
-----------------------
The resource configurations in this folder assume that you have `Kubernetes Ingress`_
set up for your cluster. If you are not using the `NGINX Ingress Controller for Kubernetes`_,
please ensure that the configuration specified in the file matches your set up.
.. _`Kubernetes Ingress`: https://kubernetes.io/docs/concepts/services-networking/ingress/
.. _`NGINX Ingress Controller for Kubernetes`: https://github.com/kubernetes/ingress/tree/master/controllers/nginx
Setup the Kubernetes service
----------------------------
Using the resource configurations is simple:
1. ``kubectl apply -f kubernetes-nginx-ingress-controller.yaml`` to configure an ingress controller with the proper settings. (If you have one set up already you may need to port the configuration to your own ingress).
2. ``kubectl apply -f kubernetes-mailu.yaml`` to create the resources required to run Mailu.
Based on the configuration, your Mailu instance should be available at ``mail.<hostname>.tld/admin`` (note that visiting just ``mail.<hostname>.tld`` will likely result in a 404 error).

# 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

## 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 follwoing command:
```bash
core@coreos-01 ~ $ docker stack rm mailu
```

# 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/

```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 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).

## 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
```
