Question

Hello everyone At my company we are evaluating Pulumi to help us manage kubernetes infrastructure on multiple clouds We are just starting out One thing we are trying to get straight in our minds is the Project and Stack relationship and practices the community follow From reading through the documentation we want to create a project and then add stack s to that project I am curious and wondered if anyone would mind commenting on how they setup up and organise their `project` and `stack` We are using pulumi version v3 19 0 Thanks

I can t quite grasp how to start out a project Should we use `pulumi new` command but only generate a project Then to add a stack `pulumi stack init`

green-stone-37839 · Answer

By default `pulumi new ` will create a project and ask you to create a single stack as well If you d like to add additional stacks to a project `pulumi stack init ` is the command you d use

acceptable-notebook-17653 · Answer

Thanks I was hoping we could somehow use `pulumi new` to add more stacks as we would benefit from pulumis built in ability to install dependencies etc

green-stone-37839 · Answer

A common use case for setting up projects and stacks is to associate your Pulumi projects to an application and stacks to different environments So say you had a 3 tier web app called MyWebApp the project would be `MyWebApp` and your stacks could be associated to your different environments like dev test stage prod etc

Thanks I am wondering how we would spin just the kubernetes infrastructure In our minds we would have in a git repository a top level directory called clusters which is also the project Then we would have a number of sub directories which are the stacks e g ``` clusters eks eu 01 eks eu 02```

green-stone-37839 · Answer

Yeah that s a useful pattern

acceptable-notebook-17653 · Answer

So far I tried ```pulumi new go generate only name clusters description Kubernetes clusters ```

acceptable-notebook-17653 · Answer

and then I setup the stacks `pulumi stack init stack eks eu 01`

green-stone-37839 · Answer

By default stacks will be located in the same directory as the `Pulumi yaml` file which tracks the project

acceptable-notebook-17653 · Answer

but they are basically empty and I don t get the benefit of the buitin ability of the cli to setup the environment for the stack

green-stone-37839 · Answer

By environment for the stack do you mean configuration values

acceptable-notebook-17653 · Answer

yeah so if we use python for our project the stacks don t get setup with a virtual env for example

acceptable-notebook-17653 · Answer

does that make sense

acceptable-notebook-17653 · Answer

So if I run the following commands

acceptable-notebook-17653 · Answer

```pulumi new go generate only name clusters description Kubernetes clusters at <http example com|example com> dir clusters cd clusters pulumi stack init name eks eu 01```

acceptable-notebook-17653 · Answer

I end up with this layout

acceptable-notebook-17653 · Answer

```clusters Pulumi yaml eks eu 01 lt stack go mod lt this seems redundant main go lt this too```

acceptable-notebook-17653 · Answer

In the above example the root stack seems not useful for our use case and the stack doesn t contain anything

acceptable-notebook-17653 · Answer

Which results in the desired stacks from the pulumi service ```pulumi stack ls NAME LAST UPDATE RESOURCE COUNT URL eks eu 01 n a n a <https app pulumi com example clusters eks eu 01>```

acceptable-notebook-17653 · Answer

I then want to add another stack so I run ```pulumi stack init stack eks eu 02```

acceptable-notebook-17653 · Answer

For those stacks I have to manually create the directory `mkdir eks eu 02`

acceptable-notebook-17653 · Answer

It feels like I am not understanding the expected use of Projects and Stacks

acceptable-notebook-17653 · Answer

I think I get this now So in our use case a project contains a program that contains a resource in our case an eks cluster A stack is used to feed that program with specific and different configuration

< acceptable notebook 17653> I m happy to jump on a call with you to talk through this if it makes it easier to grok

billowy-army-68599 · Answer

but I think you ve come to the correct conclusion program the Pulumi code that is run by the pulumi program stack a reusable instance of a Pulumi program with unique configuration It exists within a project and then can be many stacks project a grouping of a program and one OR many stacks

billowy-army-68599 · Answer

you shouldn t have to create a new directory for each stack

acceptable-notebook-17653 · Answer

Thanks so much for the offer < billowy army 68599> and for confirming I am on the right course now thumbsup The penny finally dropped
