mstein11 opened a new issue #10777: URL: https://github.com/apache/druid/issues/10777
### Affected Version Druid Version: 0.20.0 OpenShift Version: 4 ### Description When trying to start Druid in an OpenShift environment based on the [Helm-Chart](https://github.com/helm/charts/tree/master/incubator/druid), it fails. The Deployments of Druid-Broker, Druid-Coordinator, Druid-Router and Druid-Historical all fail start start their pods because of missing permission to create files at the container start. We assume this is because OpenShift does not run the pods as User 1000 but rather as a random UserId and the random User is not permitted to manipulate some files. We further assume, that owning the required files by the root group (group Id 0) and making those files writeable by the group will alleviate the issue - as described [here](https://stackoverflow.com/questions/42363105/permission-denied-mkdir-in-container-on-openshift) and [here](https://docs.openshift.com/container-platform/3.3/creating_images/guidelines.html#openshift-container-platform-specific-guidelines) We use the default helm values to deploy the druid to openshift. ## pod logs Druid-Broker 2021-01-19T08:01:06+0000 startup service broker Setting druid.host=10.86.0.214 in /tmp/conf/druid/cluster/query/broker/runtime.properties Setting
