A possible workaround is asking Terraform to SSH on the instance, and wait until it is able to perform a connection before marking the instance as ready.

  # 07-aks-cluster.tf
  
  # Network Profile
  # Kubenet is a kubernetes network configuration plugin for your AKS cluster. Nodes get an IP address from
  # the AKS subnet, and pods receive an IP address from a separate address space entirely. The source IP address
  # of the traffic is NAT'd to the node's IP address.
  
  # With kubenet there's NO Pod-to-Pod communication because they don't have their own public IPs.
  # User Defined Routing (UDR) and IP forwarding is used for communication between pods across nodes.
  
  # Kubenet is the preferred method since you get more pods per node and the AKS Cluster scales to a bigger number.
  # With kubenet Max Number of Pods per Node: 110

I'm getting questions about Terraform vs Kubernetes for managing infrastructure resources.

I make the distinction by treating Terraform as a frontend tool that interacts with control planes that present **its** resources through a declarative interface. Ownership is key.

1/ Yesterday we released v2.1.0 of the @HashiCorp Terraform provider for @HelmPack with a cool new feature: diffs of the @kubernetesio manifests that Helm is sending to the cluster!

So, what does this look like? Let's see ...

— Phil, in the 🏜️ of Arizona (@PhilipSautter) April 2, 2021

This is very common. Terraform doesnt give workload portability. It gives workflow portability

By keeping the same workflow it improves adoption because it doesn’t matter if your managing EC2 or Pagerduty the same lang and tools work. It lowers switching costs through workflow https://t.co/wSOZYjZMm3

— Justin Garrison (@rothgar) July 29, 2021

Unfortunately I think this is the biggest misconception that orgs have when deciding to adopt Terraform. It's "cloud agnostic" in the same way that Python is cloud agnostic. You still need vendor specific libraries. The only thing you standardize on is syntax and workflow

— Noah Mercado (@noah_mercado) July 29, 2021

It's not controversial to provision resources with code. It shouldn't be controversial to deploy and manage resources with code.

Yes. If it’s anything reasonably complex, my process is:
1.) Build w/ UI
2.) Gen w/ #Terraformer (local state)
3.) Fix crazy codegen-ed names
4.) Import TF, verify Cloud == State == #Terraform
5.) rm -rf the manual version
6.) Recreate from TF
7.) Test and iterate w/ IaC

— Ryan Hochstetler (@ryanhos) January 19, 2022

Let's continue to Terraform🚀

The value of a Terraform variable can be set multiple ways, including setting a default value, interactively passing a value when executing a terraform plan and apply, using an environment variable, or setting the value in a .tfvars file.
