Antrea ARM support

Starting with Antrea v0.13, we provide Antrea Docker images for both the arm/v7 and arm64 architectures. At the moment, the standard Antrea Docker manifest (projects.registry.vmware.com/antrea/antrea-ubuntu) does not include support for ARM, and the image name needs to be updated manually in the Antrea Kubernetes YAML manifest when deploying Antrea on a cluster which includes ARM Nodes.

To download the manifest for Antrea v0.13.0, substitute the image name, and deploy Antrea, you can use the following command:

curl -sL https://github.com/vmware-tanzu/antrea/releases/download/v0.13.0/antrea.yml | sed 's/antrea\/antrea-ubuntu/antrea\/antrea-ubuntu-march/' | kubectl apply -f -

Or to deploy the latest version of Antrea (built from the main branch), use:

curl -sL https://raw.githubusercontent.com/vmware-tanzu/antrea/main/build/yamls/antrea.yml | sed 's/antrea\/antrea-ubuntu/antrea\/antrea-ubuntu-march/' | kubectl apply -f -

In a future release, we will update the standard Docker manifest for Antrea to support ARM architectures, and this manual edit will not longer be required.

Note that while we do run a subset of the Kubernetes conformance tests on both the arm/v7 and arm64 images (using k3s as the Kubernetes distribution), our testing is not as thorough as for the amd64 image. However, we do not anticipate any issue.
