A few days ago DigitalOcean released their Managed Kubernetes service, as I had a little time this afternoon I decided to give it a spin. Each of the public clouds has a Kubernetes service now, I covered these in the third edition of Mastering Docker↗ . The general gist of the chapter was that both the Microsoft Azure and Google Cloud offerings were both excellent. However, the Amazon Web Services offering was an over-complicated mess. ...

It has been 270 days since my last post, so what I have been doing with my time? Well, I have been busy writing, just not this blog. Not only have I wrote and released Learn Ansible↗ , but also I have updated the Second Edition of Mastering Docker↗ bringing it up to date with the release of the Third Edition of Mastering Docker↗ which is now available from Packt Publishing↗ . ...

Over the last six months the Docker Store, which was first introduced as a private beta nearly a year and a half ago in June 2016, has come on leaps and bounds. It has quickly, but without much fanfare, become a one stop shop for all things Docker, with the both the documentation and home pages linking back to content now hosted on the store. So what is the Docker Store? In short, it is a market place for containers, plugins and also Docker itself there is a mixture of free and also paid content from both Docker themselves as well as third part providers. ...

As I had some free time this weekend so I thought it would be good to have a play with the recently released preview of Rancher 2.0. Please do not follow along with this post, you will see why towards the end !!! When I last wrote about Rancher, is was back in June 2016↗ , in that post I launched Rancher locally and used it target a few VirtualBox VMs. Rather than Virtual Box VMs I am going to use a cloud service, but I am going to be running it locally again, to do this launch the container I ran the following command; ...

My fifth book has now been published, and is avilable from Packt↗ publishing; Kubernetes has established itself as the standard platform for container management, orchestration, and deployment. It has been adopted by companies such as Google, its original developers, and Microsoft as an integral part of their public cloud platforms, so that you can develop for Kubernetes and not worry about being locked into a single vendor. This book will initially start by introducing serverless functions. Then you will configure tools such as Minikube to run Kubernetes. Once you are up-and-running, you will install and configure Kubeless, your first step towards running Function as a Service (FaaS) on Kubernetes. Then you will gradually move towards running Fission, a framework used for managing serverless functions on Kubernetes environments. Towards the end of the book, you will also work with Kubernetes functions on public and private clouds. ...

This morning, like a lot of the Docker community, I receieved an email I had been waiting for since November, confirmation that Kubernetes on Docker for Mac had made its way through to a public edge release. The version of Docker I was running was on the stable channel; The first thing I did was open up the preferences; ...

It has been a while as I have been busy writing, I thought I would spend some of my freetime having a very quick play with Ansible AWX↗ , which is the Open Source version of Ansible Tower↗ . I created the following Vagrantfile to launch a CentOS 7↗ server; Ansible AWX 1/3 # -*- mode: ruby -*- # vi: set ft=ruby : VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.box = "centos/7" config.vm.provider :virtualbox do |v| v.memory = 4048 v.cpus = 2 v.customize ["modifyvm", :id, "--natdnshostresolver1", "on"] v.customize ["modifyvm", :id, "--ioapic", "on"] end config.vm.define "awx" do |awx| awx.vm.hostname = "awx.local" awx.vm.network :forwarded_port, guest: "80", host: "8080" awx.vm.provision :ansible do |ansible| ansible.playbook = "playbook.yml" ansible.become = true end end end This launches the following playbook.yml which prepares the CentOS 7 box by installing Docker and the other prerequisites need to build and launch AWX; ...

It has been a while since I have posted, since Docker Bootcamp was published I have been hard at work on the second edition of Mastering Docker for Packt↗ which is now available from https://www.packtpub.com/en-us/product/mastering-docker-9781789618686↗ as well as Amazon and all other book stores.
