Grafana UI customisation - Docker image

Hi Team,

I have a requirement to customize the grafana UI, which has been used as an image pulled from docker hub and ran as an container.

I need to make modification to the Grafana UI and add “This system is for authorized users only. We may monitor, record, and disclose all activity and information on this system, subject to local law” at the end of login page.

I ran the grafana container and then logged into the container by using “docker exec -it ‘containerId’ /bin/bash”. Modified the login.html from the path /usr/share/grafana/public/app/partials and saved it.

Restarted my container and i didn’t see my changes in Grafana login-UI.

Can you please help.
