Installing BEL (Demo profile)
Installing BEL on any Kubernetes cluster is easy. In this guide, we’ll show you how to do just that.
Step 0: Get your license key
BEL requires a valid license key to run. Log into the Buoyant portal and follow the instructions there. You should end up with an environment variable like this:
export BUOYANT_LICENSE=[LICENSE]
Step 1: Get the CLI tool
Once you have your license key, the next step is to download and install the BEL CLI:
curl --proto '=https' --tlsv1.2 -sSfL https://enterprise.buoyant.io/install | sh
Follow the instructions to add the BEL linkerd CLI to your system path.
Verify that the CLI is installed and running the expected version with:
linkerd version --client
You should see:
Client version: enterprise-2.17.1
Finally, validate that your Kubernetes cluster is ready for installation:
linkerd check --pre
Step 2: Install BEL
At this point, we’re ready to install BEL on your cluster.
Using the CLI to install BEL is quick and easy, but note that the TLS certificates generated by this installation will expire in a year. If you expect your Linkerd installation to run for more than a year, please use Helm or BEL’s lifecycle operator.
To install BEL, run:
linkerd install --crds | kubectl apply -f -
linkerd install | kubectl apply -f -
If you are on GKE 1.29+, you need to set a custom clusterNetworks value. Learn more
--set clusterNetworks=34.118.224.0/20\,10.0.0.0/8\,100.64.0.0/10\,172.16.0.0/12\,192.168.0.0/16\,fd00::/8
For more information see the GKE docs.
Step 3: Verify your installation
After the installation is complete, you can verify the health and configuration
of Linkerd by running the linkerd check command:
linkerd check
That’s it!
Congratulations! You have successfully installed BEL onto your cluster. Note that your installation is optimized for non-production traffic such as demos and experiments. To configure a production install, please see our full BEL installation guide.
Happy meshing!
