Demystifying Docker overlay networking

Docker overlay networking is insanely simple to configure. I mean insanely simple! But lurking beneath the simplicity of the setup are a bunch of moving parts that you really wanna understand if you’re gonna deploy this stuff in your prime-time production estate. Anyway… last week I attended the Docker Open Systems Summit in Berlin and… Read More »

Docker on the Cloudcast

Last week I appeared as a guest on The Cloudcast. I talked with Brian for 40 minutes about Docker and how important it is for IT Ops to get involved and get up to speed. It’s a cracking podcast and I highly recommend you listen to it regularly. Also, if you’re IT Ops or DevOps,… Read More »

Anyone want container scars!

Most people think Docker is just for developers. Comments like this from Keith Townsend’s CTO Advisor blog are all over the internet: “… It’s obvious that Docker is a company focused on developers opposed to infrastructure…” While I don’t necessarily agree with Keith‘s comment, I hear it enough to know that plenty of people see it… Read More »

Docker 1.12 The Game Changer

It’s no secret that Docker and containers have been threatening to change the world for a while now. And they already have for some of us. But you know what… there’s always been something missing, something preventing it from taking off big style. Like a missing ingredient or something. Well it’s missing no more! WARNING:… Read More »

Docker Launches Kubernetes Killer

DISCLAIMER: This is all my personal opinion. As always, I reserve the right to be totally and utterly wrong about everything 😀 So Docker, Inc. just announced native clustering and orchestration. TLDR; I reckon it’s the biggest thing to happen to Docker since Docker, and I expect it to be a game-changer.

Docker Cloud: Why all the complaining

Here’s my summary of the situation – The Docker Cloud service used to be called Tutum and it used to be free. Since then, Docker, Inc. acquired Tutum, re-branded the product as “Docker Cloud”,… Read More »

Docker on Windows: State of Play

Just a few *very quick* and typo-riddled thoughts on what I understand to be the state of play with containers on Windows. I’m basing this on a session I attended at Dockercon that had a John Starks from Microsoft talk about Windows and Cotnainer internals and also perform some demos. First up….. it’s quite clear… Read More »

Enterprise Docker Discussion Group

I just created a new LinkedIn Group called “Enterprise Docker”. Raison d’être: To discuss all things relating to Docker and container use in the enterprise! So stuff like: Who pays for Docker and container infrastructure in enterprises What commercial support is available and what it’s like What does the Docker ecosystem need to do better in… Read More »

Integrating Docker with Devops Automated Workflows

A few weeks ago I released a lightning fast (~1 hour) video course over at Pluralsight showing how to integrate Dockerized apps into a CI/CD automated workflow using some cool new features on Docker Hub. Docker’s hot right. And we’ll be royally shafted if we don’t bring it under the control of our existing operational processes and… Read More »

Production in the Cloud

This is my “Production in the Cloud” presentation form the recent TECHUNPLUGGED event in Amsterdam. The skinny: It’s my opinion that public cloud services such as Amazon Web Services (AWS) and Microsoft Azure are ready for many enterprise production workloads. More than most of us think. Sure…… there’ll be cases where they’re not a fit.… Read More »
