I followed this tutorial to create a Kubernetes cluster on Azure to run build agents: http://www.chrisjohnson.io/2018/07/07/using-azure-kubernetes-service-aks-for-your-vsts-build-agents/
To recap what is there: a helm chart to do a deployment with a secret and a config map. For this deployment I created a kubernetes cluster on Azure with all default settings and it is pulling an image from the docker hub with vsts build agent installed.
All was working fine, but recently pods started to be evicted pretty regularly, the message on them is
Message: Pod The node was low on resource: [DiskPressure].
How can I fix this issue?
