Docker also use package up the contents of the containers in layers, rather than a complete snapshot. As such, containers can be smaller than a virtual machine whilst providing equivalent functionality. Lightweight - unlike a virtual machine, containers don’t need to contain an entire operating system in order to function.Except with Docker we get these extra benefits: We could get broadly the same effect using a virtual machine running Linux. Reducing system administration time and increasing confidence that everything will work (just about) everywhere🤞. The number one benefit of Docker for CFD is how easy it becomes to provide identical, isolated CFD environments on any platform or operating system. So, by packaging your CFD environment (OpenFOAM & whatever other tools you may need) into a container you can, thanks to Docker run OpenFOAM pretty much anywhere. And, as the Docker Engine can be installed on almost any infrastructure, your container can be used, without modification, almost anywhere. That container can then be used on any machine running the Docker Engine.

In the same way, a Docker container lets you package up all of the code you need to run a particular set of computing tasks. The container doesn’t need to be modified to go on a ship, on a train, to be lifted by a crane or hauled on a truck. They’re standardised so they can be handled & transported wherever they end up in the world.

But, if you don’t run on multiple operating systems, don’t need to manage multiple versions/releases or you need to juice every last drop of performance from OpenFOAM, then this may not be the post for you…sorry.ĭocker is set of tools that make running, building and managing software containers much easier than it otherwise might be.īut what is a container in this context? Think of a shipping container. That’s all possible & it’s thanks to an idea called containerisation & an open-source project called Docker I could deploy the same CFD environment anywhere, without doing any extra work.the process of updating/upgrading OpenFOAM was consistent & could be done just once.behaviour was consistent across the board (scripts that worked locally, also worked in the cloud).all machines had the same CFD environment (identical OpenFOAM releases, OS versions & other software tools).I typically run OpenFOAM on macOS, and on AWS instances running Ubuntu Linux.

Meaning you can install OpenFOAM on Windows as easily as you can on Linux (especially if you’re running the Foundation version & using their Ubuntu packs).īut if you want to run OpenFOAM on multiple operating systems with a high-degree of confidence that they’re all running the same version of the code and that they’ll all behave consistently, then perhaps Docker could be useful?

A feature that lets you run Linux command-line tools alongside your usual Windows programs. On Windows that problem has largely gone away with the introduction of the Windows Subsystem for Linux. Not impossible, but not ideal, particularly if you were just looking to take OpenFOAM for a quick spin. Back then, running OpenFOAM on Windows, macOS (or even a niche Linux distribution) involved virtual machines, patching &/or compiling from source or using an unofficial port.

What problem does Docker solve for CFD?.

What is Docker? Why is it useful for CFD? What is it good/not-so-good for? And, most importantly, how do you actually use it? That’s what I hope this updated version might achieve. But I think there’s still some confusion about using OpenFOAM with Docker. Since then, both OpenCFD & The OpenFOAM Foundation have started distributing Docker-ised versions of their respective releases, easing these issues.

make it easier to work with several different versions (&/or different releases) of OpenFOAM on the same machine.
