@easayliu Also, the following error log might be a clue that you configure the OAP address incorrectly, for example, did you forget `//` after `http:`? Please provide full context when asking question
```
java.net.UnknownHostException: failed to resolve 'http:' after 2 queries
```

maybe we should update the dockerhub image's README file to `docker run --name oap-ui --restart always -d -e SW_OAP_ADDRESS=http://oap:12800 apache/skywalking-ui`

@easayliu our latest codes are what you showed, so maybe you were using an older version of helm
