I am trying to run skywalking on a local cluster (Docker Engine) using your helm chart to install it
This is the command that I ran

helm install "${SKYWALKING_RELEASE_NAME}" skywalking -n "${SKYWALKING_RELEASE_NAMESPACE}"
--set oap.image.tag=8.7.0-es7
--set oap.storageType=h2
--set ui.image.tag=8.7.0
--set elasticsearch.enabled=false

Requirement or improvement

• Please describe your requirements or improvement suggestions.

The UI pod comes up but the OAP does not, it moans about tables not being present.
By default it looks like OAP is started in no-init mode set by its env variables for the JAVA_OPTS
Looking at the OAP pod logs its moaning about tables not existing, which makes me think h2 needs to be initialized

How do I do that? Override the JAVA_OPTS with -Dmode=init or -Dmode=init-only
I cant find anything in your docs that describes how to get this to work using h2

Also is the OAP image tag *-es7 correct even when using h2 and not elastic search?
