I'm using helm to install vernemq on my kubernetes cluster

The problems is it can't start, I accepted the EULA

Here is the log:

Crash dump is being written to: /erl_crash.dump...

So where my problems at, I just use helm install vernemq vernemq/vernemq to install it.

I reproduced your issue and fixed it by using latest docker image. While installing chart it uses 1.10.2-alpine.

You can change it by pulling helm chart:

helm fetch --untar vernemq/vernemq

Then change directory to vernemq and edit values.yaml:

image:
  repository: vernemq/vernemq
  tag: latest

Save changes and install the chart, by using for example:

helm install vernemq .

When the chart is installed you can check the VerneMQ cluster status by using:

kubectl exec --namespace default vernemq-vernemq-0 /vernemq/bin/vmq-admin cluster show

and output should be similar to this:

+----------------------------------------------------------------+-------+
|                              Node                              |Running|
+----------------------------------------------------------------+-------+
|VerneMQ@v-vernemq-0.v-vernemq-headless.default.svc.cluster.local| true  |
+----------------------------------------------------------------+-------+
