我们如何在 pulumi 中只使用多个 kubernetes 配置中的 1 个配置

Question

We have 5 EKS clusters and configs are defined in same folder location. When I try to create a resource, as the stack path is common for all clusters, my resource is getting deployed in all clusters. I have to provide a condition to deploy in a single cluster.

We use github actions and in the workflows, the common stack path is declares. I am new to pulumi and typescripting, trying to figure out where i can provide condition to deploy only in single cluster with the existing setup. Any help would be appreciated, thank you in advance.

With infrastructure automation tools like Pulumi or Terraform, you usually code the setup of how you want our infrastructure to be.

In Pulumi, you code your infrastructure in a project. The documentation of what a Pulumi project is can be found here:

https://www.pulumi.com/docs/intro/concepts/project/

When you want to set this up a number of times, you use different stacks for that. Here are the docs on Stacks :

https://www.pulumi.com/docs/intro/concepts/stack/

Off interest is this sentence in the opening paragraph:

Stacks are commonly used to denote different phases of development (such as development , staging , and production ) or feature branches (such as feature-x-dev ).

You can put environment specific configuration in the stack config file (YAML). When using stacks, you end up with this in your source structure:

Pulumi.yaml       // <- Pulumi project file
Pulumi.dev.yaml   // <- Config for stack `dev`
Pulumi.prod.yaml  // <- Config for stack `prod`

I limit stack configuration to aspects like resource names, sizing config like amount of nodes, etc but not to have flags which lead to creating more/less resources. I explicitely do not want drift between my environments.

How I do it is exactly the opposite of what you want to achieve. I never have Typescript files resembling an environment.

Can you elaborate more on what the differences between your environments are?
