Create infrastructure
Creating and configuring infrastructure processes depends on the resources you choose, and it will be explained in the playbook section
Prerequisites
Before you begin, ensure you have the following:
Deployment Steps
1. Generate Hetzner API Token
Create new project in Hetzner console
Obtain API token from Hetzner console that will be used by Terraform to interact with the platform. Navigate to your project and click on SECURITY > API TOKENS > GENERATE API (give read/write access)
Paste API token in the .auto.tfvars. This will overwrite default values in variables.tf file.
2. Configure infrastructure
Choose how many servers you want to have in your cluster, what type, which part of infrastructure you want to deploy, etc:
hcloud_token = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
location_list = ["fsn1", "nbg1", "hel1"]
instances_lb = "1"
instances_minio_lb = "1"
instances_coolify_controler = "1"
instances_coolify_worker = "4"
instances_db = "1"
instances_services = "2"
instances_minio = "4"
server_type_coolify_controler = "cx11"
server_type_coolify_worker = "cx21"
server_type_db = "cx41"
server_type_services = "cx21"
server_type_minio = "cx21"
os_type = "ubuntu-22.04"
disk_size = "10"
volumes_per_node = "4"
public_net = true
3. Initialize and Apply Terraform
Initialize Terraform and apply the configuration:
cd hetzner-infra
terraform init --upgrade
terraform validate
terraform apply -auto-approve
When Terraform finishes with infrastructure creation, you need the private and public server IPs. Public IPs are needed for setting up necessary installation and configuration with Ansible. Private IPs will be used by servers for communication and load balancing for distributing traffic. When the infrastructure is up and running, we can disable public IPs and the only entry point would be our load balancer.
Terraform creates SSH private and public keys that are added to Hetzner and servers. They are also used by Ansible. Be careful with keys, you don't want to lose them.
Terrafrom outputs:
server_ips = {
"coolify_controler" = {
"coolify-controler-0" = "167.235.253.176"
}
"coolify_worker" = {
"coolify-worker-0" = "157.90.252.123"
"coolify-worker-1" = "168.119.165.118"
"coolify-worker-2" = "65.109.2.124"
"coolify-worker-3" = "49.13.126.247"
}
"minio" = {
"minio-0" = "91.107.198.134"
"minio-1" = "49.13.167.104"
"minio-2" = "65.109.141.80"
"minio-3" = "159.69.241.156"
}
"minio_lb" = {
"minio-lb-0" = "157.90.150.92"
}
"nginx_lb" = {
"nginx-lb-0" = "167.235.243.221"
}
"postgres_db" = {
"postgres-0" = "88.198.111.144"
}
"services" = {
"services-0" = "168.119.101.156"
"services-1" = "167.235.30.10"
}
}
server_status = {
"coolify_controler" = {
"coolify-controler-0" = "running"
}
"coolify_worker" = {
"coolify-worker-0" = "running"
"coolify-worker-1" = "running"
"coolify-worker-2" = "running"
"coolify-worker-3" = "running"
}
"minio" = {
"minio-0" = "running"
"minio-1" = "running"
"minio-2" = "running"
"minio-3" = "running"
}
"minio_lb" = {
"minio-lb-0" = "running"
}
"nginx_lb" = {
"nginx-lb-0" = "running"
}
"postgres_db" = {
"postgres-0" = "running"
}
"services" = {
"services-0" = "running"
"services-1" = "running"
}
}

4. Configure Ansible hosts
Add Ip addresses to the hosts file.
[coolify-controler]
167.235.253.176
[coolify-worker]
157.90.252.123
168.119.165.118
65.109.2.124
49.13.126.247
[services]
168.119.101.156
167.235.30.10
[db]
88.198.111.144
[minio]
91.107.198.134
49.13.167.104
65.109.141.80
159.69.241.156
[nginx-minio-lb]
157.90.150.92
[nginx-lb]
167.235.243.221
Now we are ready to configure individual playbooks and run them. This will install the required dependencies and configure our servers.
5. Destroy infrastructure
To destroy the infrastructure run the following command:
terraform destroy -auto-approve
