How to run development mode in docker

Hi,
I want to know how to run development mode in docker.
In my DockerFile the base image is docker.elastic.co/kibana/kibana:6.8.0
and the last line CMD /usr/local/bin/kibana-docker
how shold I modify so that the running kibana is development mode?

You need to start up kibana with the --dev. See https://github.com/elastic/kibana/blob/master/CONTRIBUTING.md#customizing-configkibanadevyml

So I need to change the content of kibana-docker script?
I have tried to add arge like
CMD [‘kibana-docker’,’- -dev’]
But it didn’t work

And it always show
ERROR Extra serve options "--dev" must have a value

I try to modify the last line of teh script /usr/share/kibana/bin/kibana in docker container
from
NODE_ENV=production "${NODE}" --no-warnings --inspect=0.0.0.0 --max-http-header-size=65536 $NODE_OPTIONS "${DIR}/src/cli" ${@}
to
NODE_ENV=development "${NODE}" --no-warnings --inspect=0.0.0.0 --max-http-header-size=65536 $NODE_OPTIONS "${DIR}/src/cli" ${@}

then the log shows the following error
