In this post, docker/setup-qemu-action, we docker/setup-qemu-action 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/setup-qemu-action 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, docker/setup-qemu-action.

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.

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:. Log in to the Docker registry: This step logs in to your Docker registry using the provided credentials stored as secrets in the repository settings. The context parameter specifies the root directory of your Docker build context. The tags parameter specifies the tags for the generated images, including the architecture suffix amd64 and arm With this workflow in place, whenever there is a pull request or a push to the main branch, GitHub Actions will automatically build and push the multi-architecture container image for both amd64 and arm64 architectures.

Docker/setup-qemu-action own investigation led me to the same change that mikeglazer identified. Your e-mail address.

But how will you ensure every environment 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, which will save you time and minimize tedious tasks. In my opinion, this tutorial is the most basic application of the term. I am applying automation to the code since I am familiar with both deployment strategies and application code. One foot in operations, the other in development. This was the original inspiration for this blog post, since I have spoken about automating things at internal Test Double events and Justin had not yet built any sort of workflow to perform these tasks before.

The problem with this environment is that nobody runs Power 9 on their desktop, and Docker Hub only offers automatic build support for the x86 architecture. It turns out that Docker provides GitHub actions that make the process of producing multi-architecture images quite simple. The code demonstrated in this post can be found in my hello-flask GitHub repository. In the repository containing your Dockerfile , create a. This is where we will place the files that configure GitHub actions.

Start the container and connect to port using your web browser. You will see the screen and can now install the OS of your choice using your keyboard and mouse. This can also be used to resize the existing disk to a larger capacity without any data loss. To change the storage location, include the following bind mount in your compose file:. To skip the download, rename your image to boot. You can use qemu-arm to run ARM64 images. By default, the container uses bridge networking, which shares the IP address with the host. If you want to assign an individual IP address to the container, you can create a macvlan network as follows:. An added benefit of this approach is that you won't have to perform any port mapping anymore, since all ports will be exposed by default.

The maa VM did start eventually though. Red Hat Learning. Try to use it and then shave off the rough spots. So I was able to start the deploy, but the logs of the actual deploy gave me: TZ runner[bb5ab] den [info]Pull failed, retrying attempt 1 TZ runner[bb5ab] den [info]Pull failed, retrying attempt 2 TZ runner[bb5ab] den [info]Pulling image failed This resulted in a rollback. Multi-architecture containers enable deploying the same image across different architectures seamlessly. The options argument supplies arguments you would give Docker at the command line if you were running it locally. You can expand on this workflow by adding additional steps for testing, deploying, or other actions as per your project requirements. It seems like a ton of work, but this gets easier the more you are exposed to it. We mount two locations from our runner into to container: the location of the library we created earlier and the directory containing the package to be tests. All Red Hat. The modified image can be found at ghcr.

This was the original inspiration for this blog post, since I have spoken about automating things at internal Test Double events and Justin had not yet built any sort of workflow to perform these tasks before. The second job in our workflow will carry out the package tests. Ajay Pratap. But, to build that image, one of the architectures must be emulated using qemu emulation. Build Docker containers 40x faster. Report a website issue. Then we use the remotes and BiocManager packages to list the package dependencies and install them. And there you have it. Ideally such testing would happen automatically whenever you make changes to a package, but providing more rapid feedback than the BBS provides. 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. The modified image can be found at ghcr.
