I have created a Kubernetes cluster in my PC (master + 2 nodes). Version is 1.13.2. Afterwards, I installed Istio using the guidelines in https://istio.io/docs/setup/kubernetes/download-release and https://istio.io/docs/setup/kubernetes/quick-start (version is 1.0.5).

After checking the status of the pods, I see that the istio-pilot pod is always in status Pending, while some other pods fail as well. After several iterations, the result is always the same.

Initially the Master node has 2 cores/4 GB RAM and I increased it to 5 cores / 6 GB RAM, but the result is still the same. There are also 2 Worker nodes with 2 cores / 2 GB RAM each.

Any ideas what the problem could be?
