install-cni

Output Kubernetes configs to install Linkerd CNI.

This command installs a DaemonSet into the Linkerd control plane. The DaemonSet copies the necessary linkerd-cni plugin binaries and configs onto the host. It assumes that the ’linkerd install’ command will be executed with the ‘–linkerd-cni-enabled’ flag. This command needs to be executed before the ’linkerd install –linkerd-cni-enabled’ command.

The installation can be configured by using the –set, –values, –set-string and –set-file flags. A full list of configurable values can be found at https://artifacthub.io/packages/helm/linkerd2/linkerd2-cni#values
