||
|
||
This docker image forked from [SaraSmiseth](https://github.com/SaraSmiseth)'s [repository](https://github.com/SaraSmiseth/prosody) provides you with a configured [Prosody](https://prosody.im/) XMPP server. Includes the _prosody-migrator_ tool for data migrations between different database types and there is also an option to create a bridges between the XMPP server and the most popular messaging services like Telegram or Matrix, via [Matterbridge](https://github.com/42wim/matterbridge). The image is based on `debian:bullseye-slim`.
|
||
The server was tested using the Android App [Conversations](https://conversations.im/) and the Desktop client [Gajim](https://gajim.org).
|
||
Multiple [architectures](https://hub.docker.com/r/sarasmiseth/prosody/tags) are supported. I use it on my raspberry pi 4.
|
||
|
||
While Conversations got everything set-up out-of-the-box, Gajim was used with the following extensions:
|
||
|
||
* HttpUpload
|
||
* Off-The-Record Encryption
|
||
* OMEMO (requires _python-axolotl_ to be installed)
|
||
* Url Image preview
|

## Features
|
||
|
||
* Secure by default
|
||
* SSL certificate required
|
||
* End-to-end encryption required (using [OMEMO](https://conversations.im/omemo/) or [OTR](https://en.wikipedia.org/wiki/Off-the-Record_Messaging))
|
||
* Data storage
|
||
* SQLite message store
|
||
* Configured file upload and image sharing
|
||
* Multi-user chat (MUC)
|
||
|
||
## Requirements
|
||
|
||
* You need a SSL certificate. I recommend [LetsEncrypt](https://letsencrypt.org/) for that.
|
||
|
||
## Image Details
|
||
|
||
### Ports
|
||
|
||
The following ports are exposed:
|
||
|
||
* 5000: proxy65 port used for file sharing
|
||
* 5222: c2s port (client to server)
|
||
* 5223: c2s legacy ssl port (client to server)
|
||
* 5269: s2s port (server to server)
|
||
* 5347: XMPP component port
|
||
* 5280: BOSH / websocket port
|
||
* 5281: Secure BOSH / websocket port
|
||
|
||
### Directories
|
||
|
||
#### Data
|
||
|
||
Path: ```/usr/local/var/lib/prosody/```.
|
||
|
||
* used for SQLite file
|
||
* used for HTTP uploads
|
||
* this is exposed as docker volume
|
||
|
||
#### Bundled modules
|
||
|
||
Path: ```/usr/local/lib/prosody/modules/```.
|
||
|
||
#### Additionally installed prosody modules
|
||
|
||
Path: ```/usr/local/lib/prosody/custom-modules/```.
|
||
|
||
#### Config
|
||
|
||
Path: ```/usr/local/etc/prosody/```.
|
||
|
||
* containing the main config file called ```prosody.cfg.lua```
|
||
* containing additional config files within ```conf.d/```
|
||
|
||
#### SSL certificates
|
||
|
||
Path: ```/usr/local/etc/prosody/certs/```.
|
||
|
||
Uses [automatic location](https://prosody.im/doc/certificates#automatic_location) to find your certs.
|
||
|
||
The http_upload module and the legacy_ssl module do not use the same search algorithm for the certificates. See [service certificates](https://prosody.im/doc/certificates#service_certificates).
|
||
|
||
The settings https_ssl and legacy_ssl_ssl in [05-vhost.cfg.lua](./conf.d/05-vhost.cfg.lua) configures the certificates to ```certs/domain.tld/fullchain.pem``` and ```certs/domain.tld/privkey.pem``` for legacy_ssl and to ```certs/DOMAIN_HTTP_UPLOAD/fullchain.pem``` and ```certs/DOMAIN_HTTP_UPLOAD/privkey.pem``` for http_upload where DOMAIN_HTTP_UPLOAD is an environtment variable.
|
||
|
||
##### Folder structure
|
||
|
||
An example certificate folder structure could look like this:
|
||
|
||
``` zsh
|
||
certs
|
||
├── conference.domain.tld
|
||
│ ├── fullchain.pem
|
||
│ └── privkey.pem
|
||
├── proxy.domain.tld
|
||
│ ├── fullchain.pem
|
||
│ └── privkey.pem
|
||
├── upload.domain.tld
|
||
│ ├── fullchain.pem
|
||
│ └── privkey.pem
|
||
└── domain.tld
|
||
├── fullchain.pem
|
||
└── privkey.pem
|
||
```
|
||
|
||
Thats how Let's encrypt certbot does it out of the box.
|
||
|
||
##### Symlinks
|
||
|
||
certbot creates the structure and uses symlinks to the actual certificates.
|
||
If you mount them like that prosody somehow does not find them.
|
||
I copied them to a folder named ```certs``` next to my ```docker-compose.yml``` and made sure to use the ```-L``` flag of ```cp```.
|
||
This makes cp follow symbolic links when copying from them.
|
||
For example ```cp -L src dest```.
|
||
|
||
##### Permissions
|
||
|
||
See official [documentation](https://prosody.im/doc/certificates#permissions) for more information.
|
||
Check [Volumes permissions](#volumes-permissions) as well.
|
||
|
||
### Run
|
||
|
||
First you need to build the image:
|
||
```bash
|
||
docker build -t prosody/xmpp .
|
||
```
|
||
|
||
Next I recommend using a ```docker-compose.yml``` file:
|
||
|
||
```yaml
|
||
version: '3.7'
|
||
|
||
services:
|
||
server:
|
||
image: sarasmiseth/prosody:latest
|
||
restart: unless-stopped
|
||
ports:
|
||
- "5000:5000"
|
||
- "5222:5222"
|
||
- "5223:5223"
|
||
- "5269:5269"
|
||
- "5281:5281"
|
||
environment:
|
||
DOMAIN: domain.tld
|
||
volumes:
|
||
- ./certs:/usr/local/etc/prosody/certs
|
||
- ./data:/usr/local/var/lib/prosody
|
||
```
|
||
|
||
Boot it via: ```docker-compose up -d```.
|
||
|
||
Inspect logs: ```docker-compose logs -f```.
|
||
|
||
### Volumes permissions
|
||
|
||
The prosody user inside the container has the `uid=999` and `gid=999`. If you use the example `docker-compose.yml` from above make sure, that the `./data` folder and the `./certs` folder have the correct permissions.
|
||
|
||
``` shell
|
||
sudo chown 999:999 ./certs
|
||
sudo chown 999:999 ./data
|
||
```
|
||
|

#### DNS
|
||
|
||
You need these DNS record pointing to your server:
|
||
|
||
* domain.tld
|
||
* conference.domain.tld
|
||
* proxy.domain.tld
|
||
* pubsub.domain.tld
|
||
* upload.domain.tld
|
||
* A SRV record for _xmpps-client._tcp.domain.tld for port 5223.
|
||
|
||
where domain.tld is the environment variable DOMAIN.
|
||
|
||
### Extend
|
||
|
||
There is a helper script that eases installing additional prosody modules: ```docker-prosody-module-install```
|
||
|
||
It downloads the current [prosody-modules](https://hg.prosody.im/prosody-modules/) repository. The specified modules are copied and its name is added to the ```modules_enabled``` variable within ```conf.d/01-modules.cfg.lua```.
|
||
|
||
There is also ```docker-prosody-module-copy``` which copies the specified modules but does not add them to the ```modules_enabled``` variable within ```conf.d/01-modules.cfg.lua```.
|
||
|
||
If you need additional configuration just overwrite the respective _cfg.lua_ file or add new ones.
|
||
|
||
### Upgrade
|
||
|
||
When migrating from prosody 0.10, you need to update the database once:
|
||
|
||
```bash
|
||
docker-compose exec server bash
|
||
prosodyctl mod_storage_sql upgrade
|
||
```
|
||
|
||
## Matterbridge
|
||
|
||
To enable bridges using **Matterbridge** simply add the service in the docker-compose.yml file. Then you need to add _toml_ config file in ```matterbridge``` directory spedifying protocols and gateways. Check [documentation](https://github.com/42wim/matterbridge#readme).
|
||
|
||
``` yaml
|
||
matterbridge:
|
||
image: 42wim/matterbridge:latest
|
||
restart: unless-stopped
|
||
volumes:
|
||
- ./matterbridge/matterbridge.toml:/etc/matterbridge/matterbridge.toml:ro
|
||
- ./matterbridge/nicks.tengo:/etc/matterbridge/nicks.tengo:ro
|
||
- ./matterbridge/out.tengo:/etc/matterbridge/out.tengo:ro
|
||
depends_on:
|
||
- server
|
||
|
||
```
|
||
## Migration tool
|
||
|
||
You need to set up ```migrator.cfg.lua``` config file before build the image. Once your server is working you could use
|
||
the migration tool in this way:
|
||
``` bash
|
||
docker exec -it prosody-docker_server_1 prosody-migrator -h
|
||
```
|
||
|
||
## Test your server
|
||
|
||
You can test your server with these websites:
|
||
|
||
* [IM Observatory](https://www.xmpp.net/)
|
||
* [XMPP Compliance Tester](https://compliance.conversations.im/)
