Setup:Installation Guide/Docker

Overview

Starting with version 4.5, BlueSpice MediaWiki can be installed with a stack of Docker container images.

Everything is built in a modular way to allow different types of setups.

The most common cases are:

1. "All-in-one" (with and without Let's Encrypt)
2. Custom database and search service
3. Custom load balancer / proxy

Architecture

Notes

• Internal HTTP connections may use non-standard ports. Those are noted next to the respective services.
  • HTTP (in-secure) is only used for internal communication within the virtual network the stack is operated in. All connections to the client use TLS.
• Proprietary ports (esp. for database connections) are noted next to the respective services.
• There may be additional services and ports in use, based on the setup. Some examples:
  • When using LDAP based authentication an LDAPS connection (port 636) is used from the bluespice/wiki containers to the LDAP-Server
  • When using Kerberos authentication, a connection (port 88) is used from the bluespice/kerberos-proxy containers to the Kerberos-Server
  • When using DeepL or OpenAI services, a HTTPS connection (port 443) is used from the bluespice/wiki containers to to the respective service
  • When using OpenIDConnect authentication, a HTTPS connection (port 443) is used from the bluespice/wiki "task" container to to the authentication provider
  • When using "Let's Encrypt" Certbot, a HTTPS connection (port 443) is used from the acme-companion container to the "Let's Encrypt" service

Step 1: Get the stack

Load project bluespice-deploy from https://github.com/hallowelt/bluespice-deploy/releases/latest and enter the sub-directory compose for Docker Compose files.

For example, run:

wget https://github.com/hallowelt/bluespice-deploy/archive/refs/tags/5.1.3.zip \
  && unzip 5.1.3.zip \
  && cd bluespice-deploy-5.1.3/compose

The directory contains the following files:

Filename	Type	Comment
bluespice-deploy	shell script	Start-up script, wrapping command docker compose and service yml files. Additional service yml files can be loaded by adding -f <filename> .
docker-compose.main.yml	yml	Main containers of the wiki (wiki-web and wiki-task).
docker-compose.persistent-data-services.yml	yml	Containers of database and search services, storing persistent data onto the file system. Optionally with external MySQL/MariaDB and OpenSearch one can skip loading this .yml in bluespice-deploy. Please then wire your services properly in the .env file.
docker-compose.stateless-services.yml	yml	Containers for caching, PDF rendering, formula-rendering and diagram editing.
docker-compose.helper-service.yml	yml	Helper containers for file system preparation and automated BlueSpice upgrade. These containers exit automatically after finishing tasks.
docker-compose.proxy.yml	yml	Container of proxy service. Can be replaced by existing proxy/load-balancer infrastructure.
docker-compose.proxy-letsencrypt.yml	yml	Additional service for auto-renewal of "Let's Encrypt" certificates. Only required when using the Let's Encrypt service and having no other TLS termination.
docker-compose.kerberos-proxy.yml	yml	Additional proxy for Kerberos based authentication.
docker-compose.collabpads-service.yml	yml	Containers of back-end services for CollabPads (included in Pro and Farm editions).
.env.sample	text	Sample for creating .env that defines key environment variables.
bluespice.service.demo	service script	Demo-file for control the BlueSpice stack as a systemctl service. One can create e.g a /etc/systemd/system/bluespice.service.

Step 2: Set up environment variables

Create your .env based on the sample file .env.sample.

Example:

# set or use your data directory 
DATADIR=/data/bluespice
VERSION=5.1.3
EDITION=free
BACKUP_HOUR=04

WIKI_NAME=BlueSpice
WIKI_LANG=en
WIKI_PASSWORDSENDER=no-reply@wiki.company.local
WIKI_EMERGENCYCONTACT=no-reply@wiki.company.local
WIKI_HOST=wiki.company.local
WIKI_PORT=443
WIKI_PROTOCOL=https
WIKI_BASE_PATH=

DB_USER=set_or_use_your_db_user_name
DB_PASS=SET_OR_USE_YOUR_DB_PASS_WORD
DB_ROOT_USER=root 
DB_ROOT_PASS=$DB_PASS
DB_HOST=database
DB_NAME=bluespice
DB_PREFIX=

SMTP_HOST=mail.company.local
SMTP_PORT=25
SMTP_USER=...
SMTP_PASS=...
SMTP_ID_HOST=...

LETSENCRYPT=false

Different editions This config works for all editions, but the main image of Pro or Farm edition needs to be obtained differently, see Pro and Farm edition

Step 3: Start the stack

Use bluespice-deploy up -d to start the stack. Once all containers are shown as "ready" you can navigate to $WIKI_PROTOCOL://$WIKI_HOST:$WIKI_PORT (e.g. https://wiki.company.local) in your preferred web browser and start using the application.

When starting the stack the first time, the wiki-task container will automatically perform the installation. It may take a couple of minutes for the process to set up the database and complete. Once it is finished, the password for the default Admin user can be found in $DATADIR/wiki/initialAdminPassword.

Additional options

Configs for LocalSettings.php

Instead of exposing the LocalSettings.php for adding additional configurations, the stack offers two entry points. After the initial installation, you can add your configs to two files in ${DATADIR}/wiki/bluespice/:

• pre-init-settings.php - Set configs before the initialization of BlueSpice's debug logging, libraries, skins, extensions and default settings. Configs set here can be picked up by the init process.
• post-init-settings.php - Set configs after the initialization, manipulating configs that have been set by the init process.

For example, if you add the following lines to pre-init-settings.php, you can then read outputted debug logs (if any) in ${DATADIR}/wiki/bluespice/logs/debug.log:

$GLOBALS['bsgDebugLogGroups']['exception'] = "/data/bluespice/logs/debug.log";
$wgShowExceptionDetails = true;

Maintenance scripts

To run maintenance scripts from MediaWiki or from other extensions, please use the wiki-task container, which handles all back-end jobs and processes. You can connect into the container in two different ways:

• run ./bluespice-deploy exec -it wiki-task bash in the compose directory for Docker Compose files
• or alternatively, run docker exec -it bluespice-wiki-task bash wherever you are on the host machine

Inside the container you can enter the wiki's code base with cd /app/bluespice/w , where one can run scripts like php maintenance/run.php update --quick, php extensions/BlueSpiceExtendedSearch/maintenance/updateWikiPageIndex.php and so on.

SSL certificates

To use a Let's Encrypt certificate for your domain name, set LETSENCRYPT=true in your .env file.

To use a self-signend certificate for your domain name, put its .crt and .key files in ${DATADIR}/proxy/certs. For example, with wiki.company.local you should prepare wiki.company.local.crt and wiki.company.local.key files.

Kerberos proxy

For implicit authentication using Kerberos, an additional proxy must be used: bluespice/kerberos-proxy . The file docker-compose.kerberos-proxy.yml contains a common configuration. It can be used instead of the regular docker-compose.proxy.yml file inside bluespice-deploy .

Make sure to have the files

• ${DATADIR}/kerberos/krb5.conf
• ${DATADIR}/kerberos/kerberos.keytab

set up properly.

The file ${DATADIR}/wiki/bluespice/pre-init-settings.php can then be used to set up "Extension:Auth_remoteuser" and the LDAP stack extensions.

SAML authentication

During the initial installation a certificate for message signing will automatically be created. It can be found in ${DATADIR}/wiki/simplesamlphp/certs/.

In order to configure a remote IdP, one must copy the IdP metadata XML to a file called ${DATADIR}/wiki/simplesamlphp/saml_idp_metadata.xml. The SP metadata can then be obtained via https://{{$WIKI_HOST}}/_sp/module.php/saml/sp/metadata.php/default-sp. It must be configured in the remote IdP.

Test authentication You can test authentication directly within the SimpleSAMLphp application. To do so, navigate to https://{{$WIKI_HOST}}/_sp/module.php/admin and log in with admin and the INTERNAL_SIMPLESAMLPHP_ADMIN_PASS found in ${DATADIR}/wiki/.wikienv

Next, the extensions "PluggableAuth" and "SimpleSAMLphp" must be enabled on the wiki. To do so, add

wfLoadExtensions( [
    'PluggableAuth',
    'SimpleSAMLphp'
] );

to the ${DATADIR}/wiki/bluespice/post-init-settings.php. Run

./bluespice-deploy exec wiki-task /app/bluespice/w/maintenance/update.php --quick

to complete the installation.

After that, the authentication plugin configuration can be applied in Special:BlueSpiceConfigManager under "Authentication".

OpenID Connect authentication

The extensions "PluggableAuth" and "OpenIDConnect" must be enabled on the wiki. To do so, add

wfLoadExtensions( [
    'PluggableAuth',
    'OpenIDConnect'
] );

to the ${DATADIR}/wiki/bluespice/post-init-settings.php. Run

./bluespice-deploy exec wiki-task /app/bluespice/w/maintenance/update.php --quick

to complete the installation.

After that, the authentication plugin configuration can be applied in Special:BlueSpiceConfigManager under "Authentication".
