Docker/setup-qemu-action how will you ensure every environment has the right version of Ruby installed and every user knows how to install all of its dependencies?

Just tried again, and still getting the same issue. Not able to find the image from the fly registry. Screenshot at I did my best to compare names, tags, and IDs, and everything looked to be correctly written out. We are using the GitHub runners to build and push the image. We may have found the issue and a workaround. It looks like sometime earlier today GitHub updated the ubuntu runner which bumped the version of BuildKit from 0.

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.

This allows us to compile the package manual pages and and PDF vignettes during testing. I docker/setup-qemu-action confirm this workaround worked for me. Iterate and improve, 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.

Using buildx we can build multi architecture containers , we can use a github action to automatically build it. We are going to need to get the latest tag to be able to properly tag the docker image and to check out the correct version:. Then we will have to setup qemu and buildx. We can define a list of platforms we want to use as a comma-separated list:. To be able to push the image to DockerHub we will have to login. To define these secrets we will have to go to the Settings section on the repository and click on the Secrets sub menu. Finally, we are going to build the image for the list of platforms we want and push it to dockerhub using the tag we have pushed to the repository:.

I recently found myself needing to generate a multi-arch Docker image for one of my projects - specifically an ARM64 compatible image. Each Docker image is represented by a manifest. A multi-arch image is actually just a manifest that contains multiple entries, 1 for each platform. To learn more, see this Docker blog post. Now that we know what a multi-arch docker image looks like under the hood, lets get started with a simple Github Action to build a Docker image. The first thing we need to do is add the setup-buildx-action step.

This influences some of the decisions made during this workflow regarding which containers to use and what we want to cache between workflow steps. Images built with the latest docker buildx and or github actions work again. If this job executes successfully we should have a cached library containing all the packages required to test the package. Red Hat Account Number. Most of these steps are pretty standard for regular users of GitHub Actions. The run section is where we provide the command to be executed inside the container. Given this, we can split our workflow into two jobs; the first installs the packages while the second runs the actual package tests. Multi-architecture containers enable deploying the same image across different architectures seamlessly. Hi I can confirm it worked for me by specifying the version! To get started with building a docker container, you need a Dockerfile :. Until then, reverting to BuildKit 0. To do this we can use the upload-artifact action. See how to build them in GitHub Actions.

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.

The GitHub Actions workflow uses the custom Docker image containing Podman mypodman:latest to build and push the multi-architecture container image for both amd64 and arm64 architectures. It seems like a ton of work, but this gets easier the more you are exposed to it. This will give the end users a clear place to mount their configuration files and be an obvious location for persistent data. In this example, the GitHub Actions workflow uses macos-latest , you can change it based on your requirement. Thanks a lot for your investigation. This allows us to compile the package manual pages and and PDF vignettes during testing. To get started with building a docker container, you need a Dockerfile :. We built Depot to eliminate the pain of emulation and other limitations above, not only in GitHub Actions but in all CI providers. This is required for multi-platform Docker image builds in GitHub Actions, as the hosted runners are Intel machines. There is one more step to go before we call it done. A secure, stable, and supported operating system. Hash An icon of a hash sign Code Name Agent The second job in our workflow will carry out the package tests. Take a nice thing and then automate it.
