SQL Sink Plugin dissapear after every ekuiper docker container restart (persistent volumes enabled for /kuiper/log, /kuiper/data, /kuiper/etc and /kuiper/plugins)

[canob]

Hi everyone,
Can anybody tell me which folder I need to add as a volume in docker to persist the installation of SQL Sink Plugin?
Because every time I restart ekuiper docker container, the rules that depend on SQL Sink Plugin are stopped, and SQL Sink Plugin is not installed anymore, and I need to reinstall every time.
The folders that I already have as persisted volumes in ekuiper docker are:

/kuiper/log
/kuiper/data
/kuiper/etc
/kuiper/plugins

Thanks in advance for your help.
