terraform-talos/oracle

OracleCloud

1. Upload the talos image to the cloud
2. Create networks (loadbalancer + controlplane)

Create compartment

This is optional stage.

First you need to prepare your compartment:

cd init
terraform init
terraform apply

It creats:

• compartment
• terraform account
• resources tags
• identity policy for terraform and CCM

Upload images

cd images

# fixme, url does not exist yet
wget https://$url -O oracle-amd64.qcow2
wget https://$url -O oracle-arm64.qcow2

terraform init
terraform apply

Create networks

• creates networks by zones and for zonal loadbalancer
• creates NAT for private networks
• creates security group and security list

make create-network

Launch the cluster

Create the loadbalancer

make create-lb

Generate Talos configs

make create-config create-templates

• Check file terraform.tfvars.json
• Create the terraform.tfvars like this

controlplane = {
  count = 1,
  type  = "VM.Standard.E4.Flex"
  ocpus = 1
  memgb = 4
}

instances = {
  "jNdv:eu-amsterdam-1-AD-1" = {
    web_count             = 1,
    web_instance_shape    = "VM.Standard.E2.1.Micro",
    web_instance_ocpus    = 1,
    web_instance_memgb    = 1,
    worker_count          = 1,
    worker_instance_shape = "VM.Standard.E2.1.Micro",
    worker_instance_ocpus = 1,
    worker_instance_memgb = 1,
  },
}

Bootstrap cluster

terraform apply
