This docker image provides you with a configured Prosody XMPP server. The image is based on debian:buster-slim.
The server was tested using the Android App Conversations and the Desktop client Gajim.
Multiple architectures 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
- Secure by default
- Data storage
- SQLite message store
- Configured file upload and image sharing
- Multi-user chat (MUC)
- You need a SSL certificate. I recommend LetsEncrypt for that.
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
Path: /usr/local/var/lib/prosody/.
- used for SQLite file
- used for HTTP uploads
- this is exposed as docker volume
Path: /usr/local/lib/prosody/modules/.
Path: /usr/local/lib/prosody/custom-modules/.
Path: /usr/local/etc/prosody/.
- containing the main config file called
prosody.cfg.lua - containing additional config files within
conf.d/
Path: /usr/local/etc/prosody/certs/.
Uses 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.
The settings https_ssl and legacy_ssl_ssl in 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.
An example certificate folder structure could look like this:
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.pemThats how Let's encrypt certbot does it out of the box.
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.
See official documentation for more information.
I recommend using a docker-compose.yml file:
version: '3.7'
services:
server:
image: sarasmiseth/prosody:v1.0.0
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/prosodyBoot it via: docker-compose up -d.
Inspect logs: docker-compose logs -f.

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.
This module lets you advertise various contact addresses for your XMPP service via XEP-0157. It is configured for the following contacts:
- abuse
- admin
- feedback
- sales
- security
- support
You can change them in 05-server_contact_info.cfg.lua.
There is a helper script that eases installing additional prosody modules: docker-prosody-module-install
It downloads the current 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.
When migrating from prosody 0.10, you need to update the database once:
docker-compose exec server bash
prosodyctl mod_storage_sql upgradeYou can test your server with these websites:
