Hey Guys, I would like to disable a possibility to perform Pulumi UP in any form. I know that there is Deployment.Instance.IsDryRun but I would like to exclude this possibility at the start of the program so I don't have to modify the stacks. An example in program.cs

if (Environment.GetEnvironmentVariable("PULUMI_DRY_RUN") == "true")
{
    return await Deployment.RunAsync<Stack>();
}
else
{
    throw new NotSupportedException("Pulumi command is not supported");
}

The problem with this approach is, the preview is called first with the variable set on true and it never gets back to this context. Is there a way to get info what command was invoked ?

It should. I'm pretty sure the program gets invoked twice, once for preview, once for the actual up and it starts the whole program from scratch each time.

@damp-smartphone-91507 - I've tested the above code and it works to only give a preview result if you run

pulumi preview

or if you run

pulumi up

. As fraser mentioned if

pulumi up

is run without

--skip-preview

(of

-if

) if will run the preview first but then not deploy. It's worth bearing in mind that I don't believe this would stop

pulumi destroy

from being run as this does not typically execute the program during destroy.
