Hands on with Docker, openSUSE Leap 15

May 4th, 2018 by

This blog is part of a series of technical blogs leading up to the release of openSUSE Leap 15. All of the blogs provide a use case regarding openSUSE Leap and the packages available in the distribution. Happy reading.

Docker is a software technology providing containers, promoted by the company Docker, Inc. Docker provides an additional layer of abstraction and automation of operating-system-level virtualization on Windows and Linux.

Docker implements a high-level Application Programming Interface to provide lightweight containers that run processes in isolation.

Because Docker containers are so lightweight, a single server or virtual machine can run several containers simultaneously.

Let’s do some hands on with Docker and openSUSE Leap 15.

== Install Docker  ==

Use GUI method

use yast2  sw_single install docker

# yast2  sw_single

Search  docker

Select docker to install

 

Use command line to install docker

use zypper to install, if you don’t want interactive use #zypper  -n install docker

# zypper  install  docker

Loading repository data…

Reading installed packages…

Resolving package dependencies…

The following 13 NEW packages are going to be installed:

 containerd criu docker docker-bash-completion docker-libnetwork docker-runc git-core git-gui gitk libnet9

 libsha1detectcoll1 python2-ipaddr python2-protobuf

The following recommended package was automatically selected:

 criu

13 new packages to install.

Overall download size: 23.2 MiB. Already cached: 0 B. After the operation, additional 117.1 MiB will be used.

Continue? [y/n/…? shows all options] (y):  Y

Check docker version when you install it

# docker  –version

Docker version 17.09.1-ce, build f4ffd2511ce9

openSUSE Leap 42.3 Cloud Images Become Available

August 22nd, 2017 by

Cloud images for openSUSE Leap 42.3 are now available for Azure, Google Compute Engine and more cloud providers.

The images for Amazon Web Services (AWS EC2) are expected to arrive soon as they were recently submitted for review by the AWS Marketplace team.

“Compared to openSUSE Leap 42.2 we were in much better shape releasing two of three images on release date (GCE and Azure) and even the delayed image was released much closer to release date than the 42.2 release,” Robert Schweikert wrote on Google Plus.

End users can choose the cloud service provider that best fits their usage model.

Leap ships with tools for uploading and managing images. The tools allow for uploading, publishing, deleting and deprecating images.

There are a couple of known things not working at the moment like the “gcloud” command in the GCE image and the automatic hostname setting in the GCE image,

Both will be worked on as time permits, Schweikert wrote.

Cloud images of openSUSE have been available in for years and users can run Docker containers in a Virtual Machine with openSUSE’s cloud image; this has been tested with SUSE Linux Enterprise Server 12, which shares a common core with openSUSE Leap.

Since releasing openSUSE Leap 42.2 in the AWS Marketplace, around mid January, roughly 220 subscribers are running openSUSE Leap. AWS customers have an opportunity to use openSUSE’s community software on AWS without any hourly-software instance charge.

SoftIron CEO announces new ARM server running openSUSE Leap

Chief Executive Officer of SoftIron, Norman Fraser, Ph.D., provides the keynote talk at the openSUSE Conference in Nuremberg, Germany, on June 24.

The keynote speaker for the openSUSE Conference today and Chief Executive Officer of SoftIron, Norman Fraser, Ph.D., made a big announcement about the release of a new powerful ARM server that comes with essential tools to get the 64-bit ARM development up and running, out-of-the-box.

Fraser announced the availability of the affordable, feature rich Overdrive 1000, which is an entry level 64-bit ARM® developer system, powered by the AMD Opteron A1100™ series processor.

“Many developers want more than what the DIY boards can offer but only need specific parts of the functionality delivered by full on enterprise systems,” Fraser said.

The Overdrive 1000 will run openSUSE Leap and comes with Apache webserver, MySQL, PHP, Xen, KVM Hypervisor, Docker and OpenJDK pre-installed so developers can get to work and see results straight out-of-the-box, according to Fraser.
