Hi Hausiowen, You can find (mostly) everything a developer may be interested in at Dashboard's HACKING.rst (https://github.com/ceph/ceph/blob/754e08017714543d71835c0deb3853603567f2b4/…, I'm sending you that commit because Github is not rendering that doc in the master HEAD commit). You can delete all front-end code, and it will still work because Angular/Typescript code is 'transpiled' into Javascript code (frontend/dist subdir), so you don't directly run the 'code' version of the dashboard. So, answering your specific question, you may either: - Run from build/ subdir: "make mgr-dashboard-frontend-build", and then restart dashboard to reload new front-end ("ceph mgr module disable dashboard && ceph mgr module enable dashboard"), - Use the development mode front-end Angular provides, which performs incremental auto-builds every time you save a change: rename proxy.conf.json.sample to proxy.conf.json and add the backend port and HTTP/S proto and run "npm run start" (this will run a new front-end server in a different port than the ceph-mgr one). Let us know if that was of help to you!
