Kubernetes provider for terraform: kubernetes_manifest

2 min read

Since version 2.8.0 of the Kubernetes provider for terraform, the kubernetes_manifest resource is no longer considered experimental. With this resource we can push any kind of Kubernetes objects using terrraform that doesn't have a specific resource for it:

resource "kubernetes_manifest" "example_km" {
  manifest = yamldecode(<<-EOF
    apiVersion: v1
    kind: Namespace
    metadata:
      name: example-ns
      annotations:
        test: example
    EOF
  )
}

Terraform: aws_security_groups empty list of SecurityGroups

2 min read

Update 10/02/2020: The new version 4.0 of the AWS provider have been released. At this point, all AWS provider plural data sources (like the aws_security_groups) that return an array of results will now return an empty list if zero results are found.

Prior to that, if when trying to use the aws_security_groups data source if the tags did not match any SecurityGroup, terraform would have returned an error instead of an empty list:

data "aws_security_groups" "eks-pod" {
  tags = {
     "NotAnActualTag" = "WontMatchAnything"
  }
}
