LINKERD: Pending External IP in Kubernetes on Ubuntu

Question

I have installed kubernetes on my ubuntu machine when I tried to run the following command I see external-IP as "pending", where svc.yml is service object in linkerd, link below

Answer 1

The yaml you specified for the Service has type: LoadBalancer . That will only work with a cloud provider - so not on your bare metal Ubuntu installation.

Modify the Service definition and specify a different type, for example clusterIP

Answer 2

I think you have insufficient memory on your machine, try this command

kubectl get nodes -o yaml | grep '\\sname\\|cpu\\|memory'

Answer 3

Try this one if you are using LoadBalancer on an on-premise / bare-metal kubernetes cluster.

https://github.com/google/metallb

From the project description :

Kubernetes does not offer an implementation of network load-balancers (Services of type LoadBalancer) for bare metal clusters. ... If you're not running on a supported IaaS platform (GCP, AWS, Azure…), LoadBalancers will remain in the “pending” state indefinitely when created .

and this project tries to solve this problem.
