Docker Update in SUSE's Containers Module

SUSE has provided a version bump to docker 1.10.3 in their containers module (with a security update 4/26). Together with their latest kernel, it provides for improved performance (e.g. starting/stopping containers).

Ubuntu 16.04 GAes and Provides Containers

Today, Ubuntu 16.04 LTS for Server is available for s390x (and a few other minor platforms :-). It provides a few interesting infrastructure options: besides OpenStack and KVM, it offers system containers with LXC/LXD; for application containers, it comes with Docker. Some aspects of what this introduces will follow here...

s390x/ubuntu:16.04 on Docker Hub

With https://hub.docker.com/r/s390x/ubuntu/, the first Ubuntu 16.04 image just appeared on DockerHub

Docker 1.10 on developerWorks

The Docker page on developerWorks now provides a new Docker binary. It's version 1.10 and provided for RHEL 7 only: SUSE officially provides Docker, and Canonical has uploaded a recent Docker version to the universe archive.

Blockchain in Containers

Neale Ferguson from Sine Nomine Associates recently pushed an interesting container image on Docker Hub: brunswickheads/openchain-peer provides a blockchain environment based on openblockchain (IBM's view and one of the efforts for hyperledger). https://hub.docker.com/r/brunswickheads/openchain-peer/ comes with a description how to use it.

"FROM golang" -- revisited

In this post, we created an image that deals with go-based containers. When tagging it golang, building works out of the box for most Dockerfiles.
Now that golang has been ported to s390x, we can look at this again, creating a golang image that bases on golang rather than gccgo:

Docker on the LinuxONE Community Cloud

The LinuxONE Community Cloud provides an open access to Linux running on a mainframe, primarily targeted at development, porting and functional testing.
Registered users can deploy recent SLES and RHEL instances. Since SLES12 SP1 along with the containers module provides Docker support, it's an easy way to play with Docker there. Try it!

The quickest way to get a container up is:

sudo -i service docker start
docker pull s390x/debian
docker run -ti s390x/debian bash
