Recent Roundcube Docker Builds
After the release of Roundcube 1.5 and the recent security updates we have also published new Roundcube Docker images. We’d like to highlight a few changes to the latest builds and give some general information about the Roundcube Docker images:
Version 1.5.1
After we removed spell.roundcube.net as the default spell checking service in version 1.5.0
the 1.5.1 images now come with aspell pre-installed and a new env variable named
ROUNDCUBEMAIL_ASPELL_DICTS to define aspell dictionaries to be installed for spell checking.
Adding them all by default would significantly increase the image size and thus they are installed
on demand.
For those who want to connect with an external spell checking API (spell.roundcube.net or
self-hosted) the env variable
ROUNDCUBEMAIL_SPELLCHECK_URI is available too.
See the README file for detailed descriptions of these variables.
Redis support built in
The new images for versions 1.4.12 and 1.5.1 now have the PHP Redis module included which allows to configure Redis as caching engine or session storage backend.
Image tagging schema
The Roundcube Docker images are available in three variants (apache, fpm and fpm-alpine)
and can be referenced by <version>-<variant>. In addition to the exact version we
also publish tags like 1.4.x-<variant> and latest-<variant> which can be used
to pull in automatic updates for the according major release branch.
The latest tag is an alias of latest-apache.
Docker Compose, Kubernetes and Helm Charts
Have a look at our examples
for complete setups with MariaDB or Postgres and Nginx using docker-compose or a set of Kubernetes
resources. Besides the plain containers and the docker-compose examples, there are also two
Helm Charts for Roundcube currently available:
