A noob question about systemctl (ubuntu)

[Joveice]

Hello,

 

So I have a service I can enable like this

systemctl start my-service@prod

so, you guessed it, it has prod, qa and test.

 

But is this the correct way to enable only prod?

systemctl enable my-service@prod

Or will this fail / enable all of them?

systemctl enable

makes it so that, when the conditions for starting a service, which are defined in its unit file, are met, it is started

systemctl start

starts a service manually

 

An enabled service won't automatically start at the moment of being enabled nor will a started service automatically  become enabled.

I know that, but I'm asking if this is the correct way for multiple instances.

Do you? You referred to both commands as enabling a service.

Are you asking about the @prod part of it?  if not you can use

systemctl enable --now thing

and be done with it.

Also, Stack Overflow saves the day again.

I'm wondering about the @prod part of it, as I only want to enable 1 of them to start when the system starts and not the others.

Assuming the service file was written correctly, then yes, adding the @prod part means you won't start or enable any @test parts and vice versa
