I'm new to systemd and would like to know what is the best strategy for restarting my web application whenever I deploy new version.

Currently I start my service on boot and it just sits there, however I would like it to restart automatically whenever I change the files since whenever I push to master on gitlab the runner gets the files, compiles and copies it to correct directory. Then I want to restart it or close it however I don't know how since to restart it requires sudo.

Here is my service file

[Unit]

After=mongod.service



[Service]

WorkingDirectory=/var/app/mywebsite/Web

Environment="HOME=/home/stan"

Environment="DOTNET_CLI_TELEMETRY_OPTOUT=1"

Environment="DOTNET_SKIP_FIRST_TIME_EXPERIENCE=1"

ExecStart=/usr/bin/dotnet run -c Release -p /var/app/mywebsite/Web/project.json



[Install]

WantedBy=multi-user.target

Here is my ci file to be more specific

before_script:

    - set DOTNET_CLI_TELEMETRY_OPTOUT=1

    - set DOTNET_SKIP_FIRST_TIME_EXPERIENCE=1

    - set HOME=/home/stan

    - cd Web

    - dotnet restore

    - dotnet build -c Release

    - cd ..

copy:

    script:

        - cp -R ./* /var/app/mywebsite/ # After this I would like to restart the website service
