Hi guys, is it possible to set

stage

dynamically in SST? For example in my case based on git branch. In Serverless Framework I’ve accomplished this via javascript file variables. Inside the file was a function which extracted git branch and returned it as a string which then became value of the

stage

variable.

you just use the

--stage

arg on whatever command you are running

Well, my point was setting the stage inside the TypeScript runtime. I can see that in

<http://sst.App|sst.App>

is

readonly

variable

stage

. I need to be able to set a value of it for example from within the

main

function.

you could simply hard code the default stage for that branch in

sst.json

.

you could just set it as an environment variable and pass whatever the env variable is to the command

@Derek Kershner won’t setting the default stage in

sst.json

do the trick? 🤔

he cant change that value in code, and I think that is deprecating

oh! that won’t work then, was there any specific reason to deprecate the default stage key from

sst.json

?

you’d have to ask the gang, I dont think they said why in the blurb

okay, I’ll do that. 🙏

The deprecation was done to support personal aws envs, with the assumption that any upstream envs deployed from CI would use the CLI flag. I'm not sure SST is really set up to be run programmatically in general

Yeah too much in the CLI boots up needing the stage. We'll eventually rework everything to support progammatic access but right now you'd have to spawn it with the --stage flag

Yep, got it. ENV variables would be the way to go, I guess.

@Filip Pyrek [AWS Hero] to add a bit of context, currently it is not possible to set/change the stage inside

main

. SST needs to know the

stage

prior to that point, ie. to setup Live Lambda environment, SST console, etc.

I see, that's a pity, thanks for the info and the discussion guys. 🙌
