tfarbe

Add color to Terraform 12 plan output.

Inspired from: https://github.com/coinbase/terraform-landscape

NOTE: if you're using terraform v11, tfarbe will not help and you should use terraform-landscape.

Example of output

Also formats the ouput for markdown diff.

For example, this:

  # module.apps.kubernetes_deployment.deployment is tainted, so must be replaced
-/+ resource "kubernetes_deployment" "deployment" {
      ~ id               = "some-app" -> (known after apply)
        wait_for_rollout = true

              ~ spec {
                  - active_deadline_seconds          = 0 -> null
                  - automount_service_account_token  = false -> null
                    dns_policy                       = "ClusterFirst"
                    host_ipc                         = false
                    host_network                     = false
                    host_pid                         = false
                  + hostname                         = (known after apply)
                  + node_name                        = (known after apply)
                    restart_policy                   = "Always"
                  + service_account_name             = (known after apply)

becomes:

# module.apps.kubernetes_deployment.deployment is tainted, so must be replaced
-/+ resource "kubernetes_deployment" "deployment" {
~       id               = "some-app" -> (known after apply)
        wait_for_rollout = true

~               spec {
-                   active_deadline_seconds          = 0 -> null
-                   automount_service_account_token  = false -> null
                    dns_policy                       = "ClusterFirst"
                    host_ipc                         = false
                    host_network                     = false
                    host_pid                         = false
+                   hostname                         = (known after apply)
+                   node_name                        = (known after apply)
                    restart_policy                   = "Always"
+                   service_account_name             = (known after apply)
