Infra Consul

Infra environment for deploy consul with Federation and vault integration in differents environments with same deploy.

Steps Simplified

Requirements

Have some dependecies accordingly what environment are you using.

Libvirtd

libvirtd needs to works in your environment.
Add follow options to your configuration.nix:

{
  users.users.myname.extraGroups = [
    "qemu-libvirtd" "libvirtd" 
    "wheel" "video" "audio" "disk" "networkmanager"
  ]; 
  virtualisation.libvirtd.enable = true;
  # optional
  boot.kernelModules = [ "kvm-amd" "kvm-intel" ];
  # optional
  services.qemuGuest.enable = true;
}

GCP

Need instalation of gcloud, or append it inside devShell.

{
  environment.systemPackages = [
    pkgs.google-cloud-sdk 
  ];
}

Get auth to GCP with:

gcloud auth application-default login

Azure

required az command. you can put it inside devShell too.

{
  environment.systemPackages = [
    pkgs.azure-cli 
  ];
}

Get auth to Azure with:

az login

Environment

If you use external VAULT, it's required to set the envs to point to it.
To set it, use:

IC_VAULT_ADDR=https://vault:443
IC_VAULT_TOKEN=root-token

Build

By default it will build libvirt

Libvirtd

To build libvirt Image to be imported use:

nix build .#qcow # or `build-qcow`

GCP

To build GCP Image use:

nix build .#gce # or `build-gce`

Azure

To build azure Image to be imported use:

nix build .#azure # or `build-azure`

Provision

Required to build image before apply.
Required access to ./result. Add this access with git add -Nf result

It will call terraform in the end with the configuration made by terranix
Converting the config.nix files in config.tf.json

In the end of provision it will output an JSON with the values of each machine created.

Operations

Defaults to libvirt

# Apply infra
nix run ".#apply" # or `nix run` or `apply`
# Destroy infra
nix run ".#destroy" # or `nix run` or `destroy`

Libvirt

Provide infra in Libvirtd environment.

# Apply
nix run ".#apply-libvirt" # or `apply-libvirt`
# Destroy
nix run ".#destroy-libvirt" # or `destroy-libvirt`

GCP

Provide infra in GCP environment.

# Apply
nix run ".#apply-gcp" # or `apply-gcp`
# Destroy
nix run ".#destroy-gcp" # or `destroy-gcp`

Azure

Provide infra in Azure environment.

# Apply
nix run ".#apply-azure" # or `apply-azure`
# Destroy
nix run ".#destroy-azure" # or `destroy-azure`

Deploy

Required access to output.json generated by provision.
Add this access with git add -Nf output.json
Required vault access. you can pass Environment or use an local vault.

Deploy uses colmena as backend.
For deploy, you can follow all patterns of provision, but replacing apply to deploy

It defaults to libvirt

nix run ".#deploy" # or `deploy`

Libvirt

For deploy to libvirt explicit use:

nix run ".#deploy-libvirt" # or `colmena deploy --on @libvirt` # or `deploy-libvirt`

GCP

For deploy to GCP use:

nix run ".#deploy-gcp" # or `colmena deploy --on @gcp` # or `deploy-gcp`

Azure

For deploy to Azure use:

nix run ".#deploy-azure" # or `colmena deploy --on @azure` # or `deploy-azure`

Vault

Use vault as pki and secret manager.
To configure it, set Environment with token and addr.
And then use:

./scripts/vault-init.sh

to configure it.

Environment

Set environment vars with addr and token. If you are using local-vault, you don't need to set it.

IC_VAULT_ADDR=https://vault:443
IC_VAULT_TOKEN=root-token

Local-Vault

Use docker-compose by arion-compose to run a dev local-vault.
For libvirt environment you can use local vault.
Start vault dev server in http://127.0.0.1:8200with:

local-vault # or arion up

K8s

Federation in Kubernetes can be configured using scripts and devShell alias.

If you are using libvirt environment, you can use an local-k8s

Federation

Configure it with federation with

./scripts/k8s/configure.sh # configure k8s

Local K8s

Start local kubernetes with k3d for libvirt local tests.

local-k8s # start k3d local
