Getting Started with Kubernetes

It’s not that long ago that Docker was the new kid on the block. And at that time not many of us really knew what it was or what it did. But I think a lot of us are past that now – we know what it is and hopefully we’re using it! Well… today… Read More »

Docker Networking Deep Dive

Love it or hate it….. networks are at the centre of everything!  And that doesn’t change with Docker. In fact, you could argue that networks are more important than ever in the emerging container world…… For example…. as good and useful as containers are, they add new emphasis to the challenge of scale.

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 »

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

So there’s a few unhappy campers in the Docker space at the moment. And it seems to boil down to money. Here’s my summary of the situation – The Docker Cloud service used to be called Tutum and it used to be free.
