puppet 3.8.3 para SLES11SP3

No es ningún secreto que odio SuSE en todas sus encarnaciones: tanto openSuSE como SLES. Hoy vamos a ver cómo instalar una versión reciente (en este caso 3.8.3) de puppet en lugar de la 2.6.18 que he visto que nos viene por defecto.

Para ello deberemos instalar los siguientes repositorios:

zypper addrepo -f --no-gpgcheck http://demeter.uni-regensburg.de/SLES11SP3-x86/DVD1/ "SLES11SP3-x64 DVD1 Online"
zypper addrepo -f --no-gpgcheck http://demeter.uni-regensburg.de/SLE11SP3-SDK-x86/DVD1/ "SUSE-Linux-Enterprise-Software-Development-Kit-11-SP3"
zypper addrepo http://download.opensuse.org/repositories/devel:languages:ruby/SLE_11_SP4/devel:languages:ruby.repo
zypper refresh

Instalamos libyaml como dependencia:

rpm -Uvh http://download.opensuse.org/repositories/devel:/languages:/misc/SLE_11_SP4/i586/libyaml-0-2-0.1.6-15.1.i586.rpm

Instalamos ruby 2.1:

zypper install ruby2.1

Realizamos la instalación rubygems desde .tgz:

cd /usr/local/src
wget https://rubygems.org/rubygems/rubygems-2.6.4.tgz --no-check-certificate
tar xzf rubygems-2.6.4.tgz 
cd rubygems-2.6.4/
ruby.ruby2.1 setup.rb

Antes de instalar puppet deberemos instalar sus dependencias, en este caso json:

gem install json

Finalmente procedemos a instalar puppet:

cd /usr/local/src/
wget https://downloads.puppetlabs.com/puppet/puppet-3.8.3.tar.gz
wget http://downloads.puppetlabs.com/facter/facter-2.4.1.tar.gz
wget https://downloads.puppetlabs.com/hiera/hiera-1.3.4.tar.gz
tar xzf puppet-3.8.3.tar.gz 
tar xzf facter-2.4.1.tar.gz 
tar xzf hiera-1.3.4.tar.gz 
cd facter-2.4.1
ruby.ruby2.1 install.rb 
cd ../hiera-1.3.4
ruby.ruby2.1 install.rb 
cd ../puppet-3.8.3
ruby.ruby2.1 install.rb

Una vez finalizado dicho proceso, ya tendremos puppet con una versión decente disponible:

sles11sp3:~ # puppet --version
3.8.3

SUSE targets simplification with OpenStack Cloud 6 release

Public privateGerman open source vendor SUSE claims its new OpenStack Cloud 6 is designed to overcome the fear of commitment that is putting IT buyers off engagement with the cloud. SUSE claims its new private cloud offering is a solution to the buying objections that potential customers have outlined.

According to SUSE’s own feedback, many companies want the cloud but think it’s too much hassle to install applications and can’t risk the disruption to their business. A recent study commissioned by SUSE found that more than 90% of large companies say they’ve already got at least one private cloud within their business, can see the advantages and would, in theory, use cloud computing for more business-critical workloads. But in practise they are not going to. Their worst fears are over installation challenges, possible vendor lock-in and a lack of OpenStack skills in the market.

SUSE claims it can address these fears and aims to convince potential clients that they won’t be subject to IT project creep. In response it is offering non-disruptive upgrades and a more business-friendly release cycle with longer support duration. This combination, it claims, will compensate for the limited skilled resources by requiring fewer upgrades and minimising disruption to production environments.

In addition, SUSE aims to offer more training to boost the available skills base with a new OpenStack training and certification scheme. SUSE is introducing the SUSE Certified Administrator-OpenStack  (SCA-OpenStack) certification along with a new training course on how to install and administer SUSE OpenStack Cloud. This is intended as a complement to, not a replacement for, existing SUSE OpenStack Cloud training. The training was developed in collaboration with the OpenStack Foundation exam development team.

A new course will specifically prepare students to take both the OpenStack Foundation Certified OpenStack Administrator (COA) exam as well as the SCA-OpenStack exam. The new course will be held unveiled at an OpenStack Summit in Texas on April the 25th.

The Cloud 6 is based on the OpenStack release Liberty, has Docker and IBM z Systems mainframe support designed to make it easier to move applications and data to the cloud. Cloud 6 also supports Xen, KVM, Hyper-V and VMware hypervisor options and the OpenStack Manila shared file system service.

Survey reveals support for OpenStack but fears over hidden costs

openstack logoAlmost all IT professionals want to adopt OpenStack but fear the hidden costs, according to a new study by SUSE Linux.

Positive sentiment could evaporate in the face of challenges such as difficult installation, skills shortages and the fear of vendor lock-ins, the report has warned.

The study was commissioned by enterprise Linux, cloud and storage infrastructure provider SUSE. Researcher Dynamic Markets interviewed 813 senior IT professionals in the US, Canada, Germany, France, Italy and the Nordics, along with 110 from the UK. According to SUSE, 80% of the UK group said they are planning to adopt or have already moved to OpenStack private cloud. But there is serious concern about the aforementioned private cloud installation challenges and possible vendor lock-in.

Though 88% of companies said they have a private cloud at work an even higher percentage (96%) said they would use a cloud solution for business-critical workloads. Almost as many, 94%, said they see infrastructure-as-a-service as the future for the data centre.

However, many respondents confessed that the practicalities of OpenStack might get in the way and gave a series of responses that indicate there may be a high degree of difficulty involved.

Almost half of UK enterprises that have tried to implement an OpenStack cloud have failed, according to SUSE. Another 57% said they found the implementation experience difficult. Meanwhile, another 30% could be about to endure an off-putting experience, according to SUSE, since this number plan to download and install OpenStack software themselves, which (says SUSE) could exacerbate their difficulties.

Despite the open ethos of OpenStack, an alarming 91% of UK respondents are wary about falling victim to vendor lock-in when they choose a private cloud infrastructure.

Keeping control of the infrastructure will be made even harder by the impossibility of finding staff, said the report, as 89% say a lack of available talent in the market is making them reluctant to embark on a private cloud project.

The Cloud may be the future but there are clear concerns about how it should be integrated and managed, according to Mark Smith, SUSE’s senior product marketing manager. With cost the primary motivator for adopting the cloud, many IT professionals worry that there will be a price to pay later, according to SUSE.
