k8s-modules

This repository contains live examples for creation of kubernetes cluster which can run env0 deployments. you can take those examples and use them as-is or fork the repo and adjust for yourself.

You can, of course, mix and match according to your own needs.

AWS

Creating a full-blown cluster installation

If you'd like to create a cluster from scratch, including a VPC and an EFS for storage, you can simply use the aws root folder as a module.

// cluster.tf
module "my-cluster" {
  source = "github.com/env0/k8s-modules//aws"

  region       = var.region
  cluster_name = var.cluster_name
}

Partial installation

You can also just pick out the parts necessary for your installation. Check the versions.tf of submodule to know which providers are needed, check the providers.tf file of the root module to know how to configure them.

For example, only create a EFS CSI driver for storage:

// csi-driver.tf
module "csi-driver" {
  source = "github.com/env0/k8s-modules//aws/csi-driver"

  cluster_name = "eks_corporation_prod"
  efs_id = var.efs_id
}

Alternative Log Storage

You can store the deployment logs on your own cloud provider, for supported cloud providers. See log-storage/README.md for more details

Installing the env0 agent

If you'd like, you can also install the env0 agent using terraform. Make sure you fill out

• var.env0_values according to the values provided to you by env0
• var.customer_values according to your features optional configuration

// agent.tf
resource "helm_release" "agent" {
  depends_on       = [module.my-cluster] // add all necessary dependencies here 
  name             = "env0-agent"
  namespace        = "env0-agent"
  chart            = "env0-agent"
  create_namespace = true
  repository       = "https://env0.github.io/self-hosted"
  timeout          = 600
  values           = [
    yamlencode(merge(jsondecode(var.env0_values), jsondecode(var.customer_values)))
  ]
}
