Terraform code to launch a AlmaLinux Ampere A1 Shape on Oracle Cloud Infrastructure (OCI) Free-Tier which automatically builds Ansible AWX
The goal of this code is to supply the minimal ammount of information to quickly have working AlmaLinux Ampere A1 instance on OCI "Always Free". This instance is confured with metadata to install required software, configure itself, and build Ansible AWX. To keep things simple, The root compartment will be used (compartment id and tenancy id are the same) when launching the instance.
Addtional tasks performed by this code:
- Dynamically creating sshkeys to use when logging into the instance.
- Dynamically getting region, availability zone and image id..
- Creating necessary core networking configurations for the tenancy
- Rendering metadata to pass into the Ampere A1 instance.
- Launch 1 to 4 Ampere A1 instances with metadata and ssh keys.
- Output IP information to connect to the instance.
To get started clone this repository from GitHub locally.
The easiest way to configure is to use a terraform.tfvars in the project directory.
Please note that Compartment OCID are the same as Tenancy OCID for Root Compartment.
The following is an example of what terraform.tfvars should look like:
tenancy_ocid = "ocid1.tenancy.oc1..aaaaaaaabcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopq"
user_ocid = "ocid1.user.oc1..aaaaaaaabcdefghijklmnopqrstuvwxyz0987654321zyxwvustqrponmlkj"
fingerprint = "a1:01:b2:02:c3:03:e4:04:10:11:12:13:14:15:16:17"
private_key_path = "/home/bwayne/.oci/oracleidentitycloudservice_bwayne-04-06-03-42.pem"
This can also be used as a terraform module. The following is example code for module usage:
variable "tenancy_ocid" {}
variable "user_ocid" {}
variable "fingerprint" {}
variable "private_key_path" {}
module "oci-ampere-a1-AlmaLinux" {
source = "github.com/amperecomputing/terraform-oci-ampere-a1-AlmaLinux"
tenancy_ocid = var.tenancy_ocid
user_ocid = var.user_ocid
fingerprint = var.fingerprint
private_key_path = var.private_key_path
# Optional
# oci_vcn_cidr_block = "10.2.0.0/16"
# oci_vcn_cidr_subnet = "10.2.1.0/24"
# instance_prefix = "ampere-a1-"
# oci_vm_count = "4"
# ampere_a1_vm_memory = "8"
# ampere_a1_cpu_core_count = "1"
}
output "oci_ampere_a1_private_ips" {
value = module.oci-ampere-a1.AmpereA1_PrivateIPs
}
output "oci_ampere_a1_public_ips" {
value = module.oci-ampere-a1.AmpereA1_PublicIPs
}
terraform init && terraform plan && terraform apply -auto-approve
The default user is "opc".
Using an ssh client, outputted external IP address, and the key this terraform created, type the following from within the directory you ran Terraform.
ssh -i ./oci-id_rsa opc@<IPADDRESS>
