terraform-kubernetes-deployment-api

This Terraform module creates a Deployment for Kubernetes along with a Horizontal Pod Autoscaler and a Service. The deployment includes a container with various configurations such as environment variables, volumes, resources, liveness and startup probes, etc.

How to use

module "deployment" {
  source  = "graphnode-technologies/deployment-api/kubernetes"
  version = "1.4.0"

  name                = "example"
  namespace           = "default"
  replicas            = 1
  image               = "nginx:latest"
  args                = ["nginx", "-g", "daemon off;"]
  service_account_name = "example-service-account"
  environment_vars    = {
    EXAMPLE_VAR = "example_value"
  }
}
