[Enhancement]: use kubeconfig in bootstrap_git resource #717
Comments
What's wrong with multiple Flux providers ? Is it because lack of "for_each" on a list of providers ? |
@JordanP, providers are only available outside of modules. Having multiple providers per-cluster where the kubeconfig (or values) is fed through outputs into the top-level flux provider for that cluster is clunky. like this (example) module "cluster-somek8s" {
source = "./modules/a-cluster-config"
}
provider "flux" {
alias = "somek8s"
kubernetes = {
host = module.somek8s.host
client_certificate = module.somek8s.cert
client_key = module.somek8s.key
cluster_ca_certificate = module.somek8s.ca
}
}
module "flux-somek8s" {
source = "./modules/a-flux-deploy"
provider = {
flux = flux.somek8s
}
depends_on = [module.cluster-somek8s] # NOTE afaik this is hard to make this module depend on the cluster being up
} I'd like to be able to have a module for a cluster where defining a cluster also includes Flux, without top-level config needing to be added. This limiting the number of steps to get components up. Please correct me if you think there's a better way to use the tooling. If this were possible, it could be able to do something like this (example) provider "flux" {}
variable "github-token" {}
module "cluster" {
for_each = toset(["sfo", "syd", "fra"])
source = "./modules/a-cluster-config-with-flux"
region = each.key
github-token = var.github-token
provider = {
flux = flux
}
} Let me know your thoughts. |
@BobyMCbobs I've previously solved this issue using the following approach:
This approach is similar to the examples in this repository To implement this solution, you would use the |
Description
As a platform builder managing multiple clusters, I need to create, manage and destroy multiple dynamic clusters without instantiating multiple flux providers, while using a kubeconfig provided from a data or resource source.
Given the complexities of Terraform providers in modules, it would allow ease of use to provide a kubeconfig on bootstrap.
TLDR;
