![]() Docker Files And Directories Software Containers MuchBut, 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.Docker is set of tools that make running, building and managing software containers much easier than it otherwise might be.But what is a container in this context? Think of a shipping container. I could deploy the same CFD environment anywhere, without doing any extra work.That’s all possible & it’s thanks to an idea called containerisation & an open-source project called DockerNever heard of either? Read on. 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) It would be pretty helpful to me if… ![]() So if only one layer of a container’s contents changes the other layers can be re-used rather than having to be re-downloaded and duplicated. 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: Why not just use a virtual machine?We could get broadly the same effect using a virtual machine running Linux. So, no waiting for your virtual machine to boot or leaving it running just in case you want to access it quickly. Quick Start — Docker is architected in such a way that starting a process in a container is almost instantaneous. Try doing that with a virtual machine image. Need to share your exact CFD environment with a client so that they can do some runs themselves? No problem — email them the Dockerfile & away they go. Being plain-text it’s readable, understandable, sharable, archivable, version controllable and easily edited. This is the recipe that describes the ingredients & the steps required to create the contents of a container. This is the main reason why it probably isn’t the approach for someone looking to juice the last drops of crunch power from their system.As a very simple illustration, I timed the execution of the standard motorbike tutorial in OpenFOAM v6. NativeBut, surely the performance takes a hit when running OpenFOAM in a container, doesn’t it?Docker introduces an additional interface between our code & the underlying system resources on Windows & Mac (less so on Linux) which can reduce performance. Plus, you can update or modify any one of those different versions completely independent of the others.Performance Comparison: Docker vs. By isolating different OpenFOAM versions in their own containers you can have multiple OpenFOAM releases (&/or versions) on one system without needing to worry about incompatible libraries or clashing language versions. Download & Install Docker Community Edition The 5-min VersionThese are the very basic steps to get OpenFOAM running on any machine in 5 mins: Here are some options for getting started. Installing OpenFOAM via DockerInstalling OpenFOAM can be ridiculously easy with Docker - it can also be ridiculously complicated & frustrating if you’re not familiar with it. The takeaway here is not who won, but that the performance gap can be negligible. Foundation Ubuntu package running natively = 5m 13sSurprised? Me too. Star wars battlefront 1 free download full version pc torrentHow you use any given container depends heavily on how it was built. OpenFOAM Foundation - Installation InstructionsInstallation is really only half of the story. Do OpenFOAM-y things in your new container, just to show it workedThe “5 mins” bit depends on your internet connection, but you can get the idea from the more-or-less realtime animation below.Both OpenCFD & The OpenFOAM Foundation use Docker to package releases for Windows, Mac and other Linux versions.Their approaches vary slightly, but you can find their detailed installation & usage instructions here: docker container run -ti cfdengine/openfoam Choose an existing image & start it (it will download the contents the first time you run it) Search the online Docker repository ( Docker Hub) for an OpenFOAM image These scripts setup how we access them and determine how we work with them. Hence the official OpenFOAM Docker versions (from The OpenFOAM Foundation & OpenCFD) have “helper” scripts to start the containers. Most of this functionality is down to how the image was built (using this Dockerfile).An OpenFOAM Docker image that was built differently will need to be used differently. That drops us into a new BASH shell, as a user called “foam”, with access to all of the codes within the container (a minimal Ubuntu install with OpenFOAM v6 but no ParaView).
