Docker 🐳

I finally have a beta invite for the native OSX version of Docker, well sort of native OSX version, as you can see from the quote below there is still a virtual machine running … Faster and more reliable — No more VirtualBox! On Mac, the Docker Engine runs in an xhyve Virtual Machine (VM) on top of an Alpine Linux distribution. The VM is managed by the native Docker application. On Windows, the Docker Engine is running in a Hyper-V VM. You do not need Docker Machine (docker-machine) to run Docker for Mac and Docker for Windows. ...

As mentioned in a post back in February I have been working on my second book for Packt Publishing↗ which is now available for pre-order. You can pre-order your copy from the Packt website↗ or Amazon↗ .

As mentioned in my previous post I have been doing a lot of work with Docker Machine↗ and Docker Swarm↗ recently, to configure mulit-host networking with the latest version of Docker I needed to use a service discovery tool. As I had played with Consul↗ in the past I decided to use that for my back-end service discovery. Now if I wanted to launch a single node then I would run the following; ...

I have been quiet on here as I am in the process of writing again, one of things I have been looking at is Dockers new networking features. This gave me an excuse to have a play with Weave. Rather than go into too much detail here, lets go all click bait because you won’t believe what happened next. I launched two hosts in Digital Ocean↗ , one in London and then one in New York City using Docker Machine; ...

I had a play with the excellent Alpine Linux↗ over the weekend. Alpine describes itself as; Alpine Linux is a security-oriented, lightweight Linux distribution based on musl libc and busybox. And by lightweight they really do mean lightweight, with an 8MB container size and a 130MB bare metal installation it is tiny. Because of this I decided to use it as the new base images for my Docker Images↗ as some of them were getting a little bloated. As you can see from the table below, the difference in the final image size is staggering … ...

As mentioned in a post a few months ago I have been working on a book about the various ways you can approach monitoring your Docker containers, I am proud to announce that it was published today by Packt Publishing↗ . You can order your copy from the Packt website↗ or Amazon↗ . A free sample of the book can be found here↗ .

I have been reading about Flocker↗ for quite a while and it’s been something I have been meaning to look at since the introduction of plugins back in the Docker 1.7 release↗ . But I have been busy looking at other parts of Docker. Since I had a few hours this weekend I thought it was about time and had a play. ClusterHQ describes Flocker as; Flocker is an open-source container data volume manager for your Dockerized application. It gives ops teams the tools they need to run containerized stateful services like databases in production. ...

One of the reasons I haven’t been posting much on here for the last fews months is that I have been busy spending my weekends and evenings writing a book called “Monitoring Docker” which is being published by Packt Publishing↗ at the end of the year. It’s now available for pre-order from the Packt website↗ and also Amazon !!! Exciting times :D
