Introduction

Dockerfile for installation of matrix open federated Instant Messaging and VoIP communication server.

The riot.im web client has now his own docker file at github.

Configuration

To configure run the image with "generate" as argument. You have to setup the server domain and a /data-directory. After this you have to edit the generated homeserver.yaml file.

To get the things done, "generate" will create a own self-signed certificate.

This needs to be changed for production usage.

Example:

$ docker run -v /tmp/data:/data --rm -e SERVER_NAME=localhost -e REPORT_STATS=no silviof/docker-matrix generate

Start

For starting you need the port bindings and a mapping for the /data-directory.

$ docker run -d -p 8448:8448 -p 3478:3478 -v /tmp/data:/data silviof/docker-matrix start

Port configurations

This following ports are used in the container. You can use -p-option on docker run to configure this part (eg.: -p 443:8448).

• turnserver: 3478,3479,5349,5350 udp and tcp
• homeserver: 8008,8448 tcp

Version information

To get the installed synapse version you can run the image with version as argument or look at the container via cat.

$ docker run -ti --rm silviof/docker-matrix version
-=> Matrix Version
synapse: master (7e0a1683e639c18bd973f825b91c908966179c15)
coturn:  master (88bd6268d8f4cdfdfaffe4f5029d489564270dd6)

# docker exec -it CONTAINERID cat /synapse.version
synapse: master (7e0a1683e639c18bd973f825b91c908966179c15)
coturn:  master (88bd6268d8f4cdfdfaffe4f5029d489564270dd6)

Environment variables

• SERVER_NAME: Server and domain name, mandatory, needed only for generate
• REPORT_STATS: statistic report, mandatory, values: yes or no, needed only for generate

build specific arguments

• BV_SYN: synapse version, optional, defaults to master
• BV_TUR: coturn turnserver version, optional, defaults to master

For building of synapse version v0.11.0-rc2 and coturn with commit a9fc47e add --build-arg BV_SYN=v0.11.0-rc2 --build-arg BV_TUR=a9fc47efd77 to the docker build command.

diff between system and fresh generated config file

To get a hint about new options etc you can do a diff between your configured homeserver.yaml and a newly created config file. Call your image with diff as argument.

$ docker run --rm -ti -v /tmp/data:/data silviof/docker-matrix diff
[...]
+# ldap_config:
+#   enabled: true
+#   server: "ldap://localhost"
+#   port: 389
+#   tls: false
+#   search_base: "ou=Users,dc=example,dc=com"
+#   search_property: "cn"
+#   email_property: "email"
+#   full_name_property: "givenName"
[...]

For generating of this output its diff from busybox used. The used diff parameters can be changed through DIFFPARAMS environment variable. The default is Naur.

Exported volumes

• /data: data-container
