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.

• blog.ogenki.io: Applying GitOps Principles to Infrastructure: An overview of tf-controller
  • Terraform can be considered a "semi-declarative" tool as there is no built-in automatic reconciliation feature. There are several solutions to address this issue, but generally speaking, a modification will be applied using terraform apply. The code is actually written using the HCL configuration files (declarative), but the execution is done imperatively. As a result, there can be a drift between the declared and actual state (for example, a colleague who would have changed something directly into the console 😉).
  • ❓❓ So, how can I ensure that what is committed using Git is really applied. How to be notified if there is a change compared to the desired state and how to automatically apply what is in my code (GitOps)?
  • This is the promise of tf-controller, an Open Source Kubernetes operator from Weaveworks, tightly related to Flux (a GitOps engine from the same company). Flux is one of the solutions I really appreciate, that's why I invite you to have a look on my previous article

  # 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
  # With Kubenet and CIDR =/24 : 251 nodes * 110 pods per node = 27.610 pods
  # With Azure CNI (instead of kubenet) and CIDR =/24 : 8 nodes * 30 pods per node = 240 pods
  
  # If we have limited IP addresses to work with, we can fit more pods in the limited IP address space because we can
  # fit more pods per node.
  
  # The Service CIDR, Pod CIDR, and Docker Bridge Access can be any address range.
  # The DNS Service IP must be any IP address that's within the Service CIDR address range.
  
  # Network settings (service_cidr, pod_cidr, docker_bridge_cidr, dns_service_ip) are commented. The below values
  # correspond to the applied default values when these settings are note set up.
  
  # Default network settings with kubenet when they are not configured:
  # Azure AKS VNet      = "10.0.0.0/8"
  # Azure AKS Subnet    = "10.240.0.0/16"
  # service_cidr        = "10.0.0.0/16"
  # pod_cidr            = "10.244.0.0/16"
  # docker_bridge_cidr  = "172.17.0.1/16" # Default. You can reuse this range across different AKS Clusters
  # dns_service_ip      = "10.0.0.10"
  
  network_profile {  # (1)
  load_balancer_sku = "Standard"
  network_plugin = "kubenet"  # use Azure CNI network plugin when windows node pools are required (not supported by kubenet)
  #service_cidr = "10.0.0.0/16"
  #dns_service_ip = "10.0.0.10"
  #docker_bridge_cidr = "172.17.0.1/16" # Default. You can reuse this range across different AKS clusters.

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 ...

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

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

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

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.
