I'm trying to install one agent on Kubernates platform according to the documentation:
Deamonset created, pod is created and status is running
but Kubernetes couln't install agent on node due to problem with space on filesystem:
dynatrace@pc-1572:~$ kubectl logs -f dynatrace-oneagent-cfppz --namespace=kube-system ... 13:25:43 Starting installer... 13:25:43 Checking root privileges... 13:25:43 OK 13:26:15 Installation started, version 188.8.131.52990, build date: 06.12.2017, PID 13207. 13:26:15 Detected platform: LINUX arch: X86 13:26:16 Detected bitness: 64 13:26:18 /opt/dynatrace/oneagent is on / 13:26:18 Error: Free space on filesystem with /opt/dynatrace/oneagent: 0 KiB 13:26:18 Error: Not enough space on /opt/dynatrace/oneagent. Required free space: 868026 KiB
I have more than 20GB left on filesystem so it's not a reason. One agent installation without Kubernetes works fine, agent can connect to the Dynatrace server without any problem and it doesn't report any problem with space in the same location:

I'm using minikube version v0.24.1 on Ubuntu 17.10.
Maybe someone have any idea what could go wrong during preparation on installation process?
Thanks in advance,

this is a known limitation of our installer and expected behavior.
We currently do not support Minikube because of incompatibility with the operating system installed within Minikube's VM. Minikube is a solution designated primarily for development purposes, not actual production deployments but if you feel that we should support it, please consider creating a RFE.
