terraform-talos/oracle

OracleCloud

1. Upload the talos image to the cloud
2. Create networks
3. Launch the loadbalancer
4. Launch the controlplane
5. Scale the cluster

Create compartment (optional)

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
