OpenShift is Red Hat's distribution of Kubernetes optimized for continuous application development and multi-tenant deployment. OpenShift adds developer and operations-centric tools on top of Kubernetes to enable rapid application development, easy deployment and scaling, and long-term lifecycle maintenance for small and large teams.
OpenShift on ARM is now Generally Available. As such, this repository is no longer in use, and the information stored herein is mostly historical.
To obtain the openshift installer and client, visit console.redhat.com. Direct downloads are also available at mirror.openshift.com.
Extract the downloaded tarballs and copy the binaries into your PATH. Then run the following from an empty directory:
$ openshift-install create install-config
You'll be prompted to choose a platform to install to - AWS is the only available public cloud option for ARM at this time.
You will need to have cloud credentials set in your shell properly before installation. The account setup steps for AWS are identical to an x86_64 install, and are described in the installer documentation.
When selecting a region, note that ARM instances are available in most, but not all, AWS regions.
You will also be prompted for a pull-secret that will be made available to all of of your machines - get this from console.redhat.com.
This will create an install-config.yaml file which defines the installation. Please verify that both architecture values are set to arm64. Also, it is recommended to change network.networkType to OVNKubernetes, but the default value of OpenShiftSDN will still work.
Now, to create the cluster, run
$ openshift-install create cluster
Once the install completes successfully (usually 45m on AWS) the console URL and an admin username and password will be printed. If your DNS records were correct, you should be able to log in to your new OpenShift on ARM cluster!
To undo the installation and delete any cloud resources created by the installer, run
$ openshift-install destroy cluster

The OpenShift client tools for your cluster can be downloaded from the web console.
Please note that pre-releases may be pruned over time. If the pre-release that you installed was pruned, the cluster may be unable to pull necessary images and may show errors for various functionality (including updates). In that case, you will need to redeploy with a new pre-release.
OpenShift is built from many different open source projects - Red Hat CoreOS, the UBI RPM ecosystems, cri-o, Kubernetes, and many different extensions to Kubernetes. The openshift organization on GitHub holds active development of components on top of Kubernetes and references projects built elsewhere. Generally, you'll want to find the component that interests you and review their README.md for the processes for contributing.
Our unified continuous integration system tests pull requests to the ecosystem and core images, then builds and promotes them after merge. To see the latest development releases of OpenShift on ARM, visit our continuous release page. These releases are built continuously and expire after a few days.
All contributions are welcome - OpenShift uses the Apache 2 license and does not require any contributor agreement to submit patches. Please open issues for any bugs or problems you encounter, or get involved in the Kubernetes project at the container runtime layer.
If you've found a security issue that you'd like to disclose confidentially please contact Red Hat's Product Security team. Details at https://access.redhat.com/security/team/contact
