If you are using the default not configured local workspace and inline programs, where is the "state" (aka list of stacks) stored. (Curious how to make something truly stateless to run on kubernetes for example)

auto.LocalWorkspace()

they would display different lists of stacks right?

Nah, the stacks are stored in the pulumi service, so they would show the same list of stacks.

ok, i wasn't sure if under the hood the "local" workspace was persisting something locally

LocalWorkspace is named as such because it depends on being able to store things like config and the project file locally before being able to execute a program. But when using inline programs like that app does, it’ll write all that into a temp directory just to allow executing the program.

Gotcha, so the only thing that matters then is that the pulumi token/credentials has access to the stack(s)

Notable exception is config. If you select a stack from a local workspace and the stack yaml file isn't present, then there is no config on the stack. You have two options: 1. run a

refreshConfig

before the update to pull the last applied config from the pulumi service 2. always set all required config values on each update

can you clarify what you mean by config in this context, the config I'm thinking of is the ENV variables my flask app is pulling in

He means pulumi config. Meaning your

pulumi.stackName.yaml

files and everything manipulated via

pulumi config

in CLI

I hope it’s OK to ask a follow up question here - is it possible to change the backend state storage for LocalWorkspace? e.g. to tell it to store in S3 rather than the Pulumi service? I wasn’t sure if it was as simple as setting Project.Backend (https://pkg.go.dev/github.com/pulumi/pulumi/sdk/v3@v3.2.1/go/common/workspace#Project) and then invoking https://pkg.go.dev/github.com/pulumi/pulumi/sdk/v3/go/auto#LocalWorkspace.SaveProjectSettings

This go example shows using the filestate backend: https://github.com/pulumi/automation-api-examples/blob/main/go/inline_secrets_provider/main.go#L93-L100

Thanks @lemon-agent-27707 ! I tried a few of the examples to see if I could find it but there’s so many 😀 If I wanted to use the S3 backend I imagine it’s just setting the url to S3?

Yes I believe you can substitute the URLs used for login outlined here: https://www.pulumi.com/docs/intro/concepts/state/

First time for everything 🙃
