Editing grafana.ini / defaults.ini

Hello,

I’am new working with grafana a little and i have a question.
I have installed Grafana with the following code:

docker run
–restart=always
–name grafana
-p 3000:3000
-e GF_SECURITY_ADMIN_PASSWORD=Solarboat
-e GF_PATHS_CONFIG=/etc/grafana/grafana.ini
-e GF_INSTALL_PLUGINS=“grafana-worldmap-panel,
grafana-clock-panel,
btplc-trend-box-panel,
jdbranham-diagram-panel,
grafana-piechart-panel,
satellogic-3d-globe-panel,
mtanda-histogram-panel”
-v /Data/grafana/data:/var/lib/grafana
-d grafana/grafana

when i want to edit the defaults.ini file (root@3a879bacde93:/usr/share/grafana/conf#) or when i want to edit the grafana.ini file (root@3a879bacde93:etc/grafana/grafana.ini) i can not open and edit these files.

What i want to do is enable smtp.

Greetings,
