linkerd2-cni chart

Giant Swarm offers a Linkerd2 CNI Managed App which can be installed in tenant clusters. Here we define the Linkerd2 CNI chart with its templates and default configuration.

Installation

The target namespace should have the following annotations and labels (use App CR's namespaceConfig to deliver them):

labels
- config.linkerd.io/admission-webhooks=disabled
- linkerd.io/cni-resource="true"
annotation
- linkerd.io/inject=disabled

Please note, the only supported namespace name is linkerd-cni.

If you're installing using the Web UI, you'll need to add the required labels and annotation to the linkerd-cni namespace by hand.

Example AppCR

apiVersion: application.giantswarm.io/v1alpha1
kind: App
metadata:
  name: linkerd2-cni
  namespace: by7t2
spec:
  catalog: giantswarm
  kubeConfig:
    inCluster: false
  name: linkerd2-cni
  namespace: linkerd-cni
  namespaceConfig:
    annotations:
      linkerd.io/inject: disabled
    labels:
      linkerd.io/cni-resource: "true"
      config.linkerd.io/admission-webhooks: disabled
  version: 0.8.0

Usage with `linkerd` cli

You can use the linkerd cli as usual, just don't forget to specify the cni plugins namespace with --cni-namespace flag.
