terraform-provider-matchbox
terraform-provider-matchbox
allows defining Matchbox Profiles and Groups in Terraform. Matchbox matches machines, by label (e.g. MAC address), to Profiles with iPXE configs, Ignition configs, or generic free-form configs to provision clusters. Resources are created via the client certificate authenticated Matchbox API.
Usage
Setup a PXE network boot environment and deploy a Matchbox instance. Be sure to enable the gRPC API and follow the instructions to generate TLS credentials.
Configure the Matchbox provider with the Matchbox API endpoint and client certificate (e.g. providers.tf
).
provider "matchbox" {
endpoint = "matchbox.example.com:8081"
client_cert = "${file("~/.matchbox/client.crt")}"
client_key = "${file("~/.matchbox/client.key")}"
ca = "${file("~/.matchbox/ca.crt")}"
}
terraform {
required_providers {
matchbox = {
source = "poseidon/matchbox"
version = "0.5.2"
}
}
}
Define a Matchbox Profile or Group resource in Terraform.
// Fedora CoreOS profile
resource "matchbox_profile" "fedora-coreos-install" {
name = "worker"
kernel = "https://builds.coreos.fedoraproject.org/prod/streams/${var.os_stream}/builds/${var.os_version}/x86_64/fedora-coreos-${var.os_version}-live-kernel-x86_64"
initrd = [
"--name main https://builds.coreos.fedoraproject.org/prod/streams/${var.os_stream}/builds/${var.os_version}/x86_64/fedora-coreos-${var.os_version}-live-initramfs.x86_64.img"
]
args = [
"initrd=main",
"coreos.live.rootfs_url=https://builds.coreos.fedoraproject.org/prod/streams/${var.os_stream}/builds/${var.os_version}/x86_64/fedora-coreos-${var.os_version}-live-rootfs.x86_64.img",
"coreos.inst.install_dev=/dev/sda",
"coreos.inst.ignition_url=${var.matchbox_http_endpoint}/ignition?uuid=$${uuid}&mac=$${mac:hexhyp}"
]
raw_ignition = data.ct_config.worker.rendered
}
data "ct_config" "worker" {
content = templatefile("fcc/fedora-coreos.yaml", {
ssh_authorized_key = var.ssh_authorized_key
})
strict = true
}
// Default matcher group for machines
resource "matchbox_group" "default" {
name = "default"
profile = matchbox_profile.fedora-coreos-install.name
selector = {}
metadata = {}
}
Run terraform init
to ensure plugin version requirements are met.
$ terraform init
See examples for Terraform configs which PXE boot, install CoreOS, and provision entire clusters.
Requirements
- Terraform v0.13+ installed
- Matchbox v0.8+ installed
- Matchbox credentials
