Docker/setup-qemu-action

But how will you ensure every docker/setup-qemu-action has the right version of Ruby installed and every user knows how to install all of its dependencies? I think there is a simpler method to this madness. This is a tutorial to automatically build and push container images for your project, docker/setup-qemu-action, which will save you time and minimize tedious tasks, docker/setup-qemu-action. In my opinion, this tutorial is the most basic application docker/setup-qemu-action the term.

Traditionally, container images were built and optimized for a specific architecture, such as x86 or ARM However, with the advent of diverse hardware architectures and the rise of cloud platforms, the need for multi-architecture support became crucial. Multi-architecture containers enable deploying the same image across different architectures seamlessly. Here's an example of a GitHub Actions workflow that builds multi-architecture container images for both amd64 and arm64 architectures when a pull request is created or when changes are pushed to the main branch:. In this example, the workflow is triggered when there is a push to the main branch or when a pull request is created or updated against the main branch. The workflow includes the following steps:.

The Bioconductor Build System BBS now includes routine package testing on Linux ARM64, but the relatively low frequency of testing means this, if a problem occurs with your package, it can take a while to identify and fix the issue using the build system alone. Ideally such testing would happen automatically whenever you make changes to a package, but providing more rapid feedback than the BBS provides. In this article we build on these previously presented ideas to describe one approach for testing package on Linux ARM64 using a continuous integration environment on GitHub Actions. The first thing to remember when using architecture emulation is that everything works much slower than when running natively - typically by at least an order of magnitude. This influences some of the decisions made during this workflow regarding which containers to use and what we want to cache between workflow steps. Some operations that might be acceptable in a standard workflow become painfully slow under emulation, and so we try reduce the number of slow steps. The first of these is to use a modified version of the Bioconductor:devel docker image which has TinyTex pre-installed. This allows us to compile the package manual pages and and PDF vignettes during testing. Installing TinyTex and the required LaTeX packages takes approximately 10 minutes on our emulated system, so there is a noticeable time benefit to using an image with it already installed. The modified image can be found at ghcr. Note: You could probably achieve a similar result by using the standard Bioconductor container and running R CMD check with the arguments --no-manual and --no-build-vignettes , however I would rather run the complete testing process in case there is problematic code in either the manual page examples or vignette. Given this, we can split our workflow into two jobs; the first installs the packages while the second runs the actual package tests. Most of these steps are pretty standard for regular users of GitHub Actions. Initially we create an empty directory on our runner. In this example this is in the runners temporary directory, but it could be anywhere.

Workaround You can either disable BuildKit or specify a working version to get back on track, docker/setup-qemu-action.

In this post, we will focus on building multi-platform Docker images, as well as Arm images, in GitHub Actions. Depot launches cloud builders for both Intel and Arm — allowing you to build multi-platform Docker images with native CPUs and instant caching across builds. By default, Docker images are built for the architecture of the machine running the build. If you build an image on an Intel machine, the image will be built for Intel. If you build an image on an Arm machine, the image will be built for Arm. If you want to build an image for a different architecture than the machine you are building on, you can specify the --platform flag during a Docker build. A Docker image can also be built for multiple architectures simultaneously.

I wrote a reusable GitHub Action workflow for one of my pet projects, rickroller. The workflow itself is very small and uses mostly well-known Actions, but encompasses a lot of complex? So let's go together through all the steps required to create a robust and reusable workflow to build state-of-the-art, multi-architecture images with GitHub Actions. The full workflow is available here: github. Use this link to consult the exact version at the time of writing. Being in , my python project is deployed using a Docker image. This image is built and pushed to a registry in multiple "processes":. It thus makes sense to create one reusable workflow, that can be called in different CI contexts. It must be available for multiple architectures. Speed and security are also important topics: the Dockerfile should be scanned for vulnerabilities, and the workflow should avoid building the same layer over and over when it can actually just build and cache it once.

This solution happily bypasses a lot of gotchas. Start exploring in the Developer Sandbox for free. Hopefully that is enough information to diagnose any issue. The same emulation techniques can then be employed on your local development environment to find a solution, before testing again in a your GitHub Workflow, and finally deploying to Bioconductor. I think there is a simpler method to this madness. Try to use it and then shave off the rough spots. Additionally, the example provided assumes you have set up secrets in your GitHub repository for your container registry credentials. Report a website issue. Simple IT automation anyone can use. Red Hat Summit. If you want to build an image for a different architecture than the machine you are building on, you can specify the --platform flag during a Docker build. To get started with building a docker container, you need a Dockerfile :.

Using buildx we can build multi architecture containers , we can use a github action to automatically build it.

Will stay tuned for when we can remove the workaround. Iterate and improve. Thanks michael. It is one of the most common methods of distributing software for self-hosting. In the beginning… First, you run tests. We run containerd on workers which might be having a problem. Build Docker containers 40x faster. Featured Red Hat Enterprise Linux. Most of these steps are pretty standard for regular users of GitHub Actions. This is happening for both registry.
