Terraform Module Collection

For Easy Provide Infrastructure, here some Terraform modules. The Modules wrappped the hcloud terraform provider, with some preconfiguration elements. This modules build the basic Infrastructure, from nolte/personal-storage-infrastructure and nolte/minecraft-infrastructure.

Terraform Modules

Repository for Shared, reuseable Terraform Modules. At the Moment the modules only useable for the hetzner.de/cloud, with the terraform Provider.

Usage

module "private_access_key" {
    source = "git::https://github.com/nolte/terraform-infrastructure-modules.git//[module_name]?ref=v0.0.5.dev"
    ...
}

Modules

module	description
`project_access_elements`	Handle the Accees Keys from a Project (wrapper for the hcloud_ssh_key).
`storage_elements`	Handle Storage Volumes (wrapper for hcloud_volume).
`computing_elements`	Handle Computing Instances (wrapper for hcloud_server), execute a preconfiguration with `CloudInit`.

Development

virtualenv -p python3 ~/venvs/development
source ~/venvs/development/bin/activate
pip install -r requirements.txt
pre-commit install

Example

Handle a Storage Volume

module "minio_storage_runtime" {
  source       = "git::https://github.com/nolte/terraform-infrastructure-modules.git//storage_elements?ref=v0.0.5.dev"

  storage_name = "minio_storage_runtime"
  storage_size = 30
  storage_labels = {
    service = "storagebox"
    type    = "runtime_storage"
  }
}

For more Information take a look to the source at storage_elements/main.tf and storage_elements/variables.tf

Example

Crate a Ready For Configure VM, with mounted Volues and preconfigured Ansible User (ready for, nolte/ansible_playbook-baseline-online-server).

handle a reconfigured computing instance

module "minio_computing_elements" {
  source                                           = "git::https://github.com/nolte/terraform-infrastructure-modules.git//computing_elements?ref=v0.0.5.dev"

  computing_instance_name                          = "${var.minio_computing_instance_name}"
  computing_instance_usage_root_key                = "${data.hcloud_ssh_key.machine_key.id}"
  computing_instance_labels                        = "${local.merged_minio_computing_instance_labels}"
  computing_instance_ssh_machine_key_id_var        = "${data.hcloud_ssh_key.machine_key.public_key}"
  computing_instance_ssh_private_key_id_var        = "${data.hcloud_ssh_key.private_key.public_key}"
  computing_instance_additional_volumes_cloud_init = "${data.template_file.cloudinit_mounts.rendered}"
}

you will find some example used in nolte/personal-storage-infrastructure or nolte/minecraft-infrastructure.
