Configuring a license secret with BEL's lifecycle automation
BEL’s lifecycle automation for Linkerd
requires a license, and by default, a buoyant-license
secret will be created
during installation. However, you may choose to create a Kubernetes secret
yourself. This guide demonstrates how to provide a license using your own
Kubernetes secret.
Prerequisites
- The
BUOYANT_LICENSE
environment variable set
Step 1: Install the BEL lifecycle automation operator
Create a license secret in the linkerd-buoyant
namespace:
kubectl create namespace linkerd-buoyant
kubectl create secret generic --namespace linkerd-buoyant buoyant-license \
--from-literal=license=$BUOYANT_LICENSE
Next, we can install the BEL lifecycle automation operator itself:
helm install linkerd-buoyant \
--create-namespace \
--namespace linkerd-buoyant \
--set buoyantCloudEnabled=false \
--set licenseSecret=buoyant-license \
linkerd-buoyant/linkerd-buoyant
Step 2: Configure the lifecycle operator with a license secret
Create a license secret in the linkerd
namespace:
kubectl create secret generic --namespace linkerd buoyant-license \
--from-literal=license=$BUOYANT_LICENSE
Configure a ControlPlane
resource with the licenseSecret
value. Note that
the example below is an abberviated configuration, see the installation
docs for a complete ControlPlane
resource.
apiVersion: linkerd.buoyant.io/v1alpha1
kind: ControlPlane
metadata:
name: linkerd-control-plane
spec:
components:
linkerd:
licenseSecret: buoyant-license
