Play with Docker

PWD is a Docker playground which allows users to run Docker commands in a matter of seconds. It gives the experience of having a free Alpine Linux Virtual Machine in browser, where you can build and run Docker containers and even create clusters in Docker Swarm Mode.

Play with Kubernetes

PWK is a K8s playground which allows users to run K8s clusters in a matter of seconds. It gives the experience of having a free Alpine Linux Virtual Machine in browser. Under the hood Docker-in-Docker (DinD) is used to give the effect of multiple VMs/PCs.

Crafting Your Cloud-Native Strategy

A cloud-native organization's goal is to provide its business with an effective, sustainable means of innovating. This eBook shares cloud-native practices and technologies to fully automate the application stack infrastructure layers.

Michael Coté finished his latest cloud book.

Harbor by VMware

Project Harbor is an enterprise-class registry server that stores and distributes Docker images. Harbor extends the open source Docker Distribution by adding the functionalities usually required by an enterprise, such as security, identity and management.

Digital Rebar

For physical infrastructure, Digital Rebar functions as a fully integrated Cobbler/Foreman + Ansible Tower (or Juju + MaaS) with the added bonus of being able to configure RAID, IPMI and BIOS. Furthermore, Digital Rebar is not opinionated about scripting tools so you can mix and match Chef, Puppet, Ansible, SaltStack, or even Bash.
cloud

For cloud infrastructure, Digital Rebar provides a hybrid cluster install like Terraform, but with an ongoing iterative operation and upgrade strategy.

Should at least be buzzword-compatible.

Building Docker 1.12.0 (with Swarm Mode)

Manual to build Docker 1.12.0 from source on an Odroid-C2. I followed the main steps to build 1.13.0 on mine and didn't need to implement any of the bugfixes mentioned in the article. Yay for me.

Docker Networking 101 - Host mode

How Docker host mode works - useful if you need the hosts network stack in your Docker container.

Deutsche OpenStack Tage

Der Schwerpunkt der Konferenz liegt auf dem Enterprise Einsatz der Cloud Computing Software OpenStack. Namhafte Entwickler und Vertreter großer Unternehmen werden die Einführung und den Betrieb von OpenStack anhand von Best Practices und Case Studies vorstellen.

Klingt auch nach einem interessanten Event.

Docker Blog: Introducing Docker 1.13

Ever been bitten by the dreaded Error response from daemon: client is newer than server problem because your Docker CLI was updated, but you still need to use it with older Docker engines?

Starting with 1.13, newer CLIs can talk to older daemons.

Finally!

janakiramm/wp-statefulset - Deploy a Highly Available WordPress Instance as a StatefulSet in Kubernetes 1.5

PetSets sind jetzt StatefulSets. Auch wenn NFS sicher nicht ideal für Distributed Storage ist, ist das ein guter Walkthrough zum Betreiben einer Stateful App in Kubernetes.

 

KubeVirt

KubeVirt is a virtual machine management architecture built around Kubernetes, implemented as an extension to Kubernetes. The aim is to provide a common ground for virtualization solutions on top of Kubernetes.

Mal im Auge behalten, klingt interessant.

ClusterHQ Folds, Flocker Lives On

In a particularly well-titled blog post, ClusterHQ CEO Mark Davis blamed the company’s failure on the fact that a lot of other persistent storage options for containers have evolved in recent years, which made Flocker less of a big deal than it once was.

Setting up persistent storage in a container ecosystem is still a big hassle though. Seems Flocker is now an option not to consider unless it is clear how the open-source project continues.

Intercloud: Cisco schließt 1-Milliarde-Dollar-Cloud

Ebenfalls keine gute Nachricht ist das Intercloud-Ende für die Initiatoren der Open-Source-Cloud-Software Openstack, auf der die Cisco-Cloud-Plattform basiert. Vor Cisco hatte schon HP seiner Openstack-Cloud-Lösung Helion den Stecker gezogen. Auch Openstack-Mitentwickler Rackspace hat der Lösung mittlerweile den Rücken gekehrt. 

Da kommt wohl Bewegung in den OpenStack-Business-Markt.

Cloud Native Strategy Toolkit

Over the last year I've spoken with many people at large organizations in the thick of improving how they do software. This “journey” goes by many names: “digital transformation,” putting a “cloud strategy” in place, or as my company Pivotal puts it, becoming “cloud native.” Some are annoyingly clever enough to just call it “what we’ve always done.”

Draft of the second edition of Cloud Native Journey by Michael Coté of Software Defined Talk fame.Goes on my To Read list.
