New RHSCL-based Docker images that are now in beta let you easily build your own application containers even without writing any Dockerfiles. Here is an example of a Ruby on Rails application built with the Ruby 2.2 image using the PostgreSQL 9.4 image as a database backend.

Red Hat Software Collections 2.0 Docker images, Beta release

Red Hat Software Collections 2.0 Docker images, Beta release

I’m very happy to announce that Docker images based on collections from Red Hat Software Collections (RHSCL) 2.0 are in beta testing.  The images are available from the Red Hat Container Registry, and we’ve got the set of collections for language, databases and web servers covered – a complete list is below.

If you’ve not tried out the Docker package from RHEL7 Extras, you need to enable the Extras channel, install the docker page, and start the docker service; an extended guide for RHEL Docker is available here.  Once you are set up, pulling the RHSCL Docker images is very simple… for example, you can fetch the Python 3.4 image as follows:

Dockerfiles now available for Red Hat Software Collections

Dockerfiles now available for Red Hat Software Collections

Shipping_containers_at_ClydeWe recently announced that we’ve made available a set of Dockerfiles for Red Hat Software Collections.  We are making these available since we think they may be useful to customers looking to build more complex application containers on top of RHEL and RHSCL. We don’t intend the Dockerfiles to produce useful standalone images which you’ll immediately put in production – the Docker images which these create are very simple containers which give you RHEL plus the basic set of packages from a particular RHSCL collection.

There are two different ways to get your hands on the Dockerfiles:

  1. From the upstream source at github 
  2. From a new package, rhscl-dockerfiles, which we’ve shipped in the RHSCL channels – both for RHEL6 and RHEL7

You might already heard about DevConf conference in Brno (February 7-9th). If not, it’s an open conference for all Linux and JBoss Developers, Admins and advanced Linux users organized by Red Hat Czech Republic. There will also be a lab dedicated to Software Collections on Friday 3:50-5:20.  Maintainers of Red Hat Software Collections will attend the lab, so you have great opportunity to ask how to add new modules into a Ruby collection or whatever bothers you.
What’s the lab content?
  • We’ll be presenting how to build collections.
  • We can show you how to build your collection locally or in copr.
  • But most of all we are looking forward to your questions.

The conference program will be available at: http://devconf.cz/schedule
