Hi Team,

Found solution, we need to create one more file under /etc/systemd/system with name of <service>.service.d and keep the required environtment variable on <file>.conf

Below is the explanation:

One particularly interesting solution is to use /etc/systemd/system/myservice.service.d directory. Unlike other solutions, this directory is supported by systemd itself and therefore comes with no distribution-specific paths.

In this case, you place a file like /etc/systemd/system/myservice.service.d/local.conf that adds the missing parts of unit file:

[Service]
Environment="FOO=bar baz"

Afterwards, systemd merges the two files when starting the service (remember to systemctl daemon-reload after changing either of them). And since this path is used directly by systemd, you don't use EnvironmentFile= for this.

Hi Narayana,

When you say "if execute using dotnet then it is staring without issue" where are you starting it from? The same location as suggested by the service?

 

Regards,
Francisco
