## Hosts
|
||||
|
||||
### Container Linux
|
||||
Typhoon uses the [Ignition](https://github.com/coreos/ignition) system of Fedora CoreOS and Flatcar Linux to immutably declare a system via first-boot disk provisioning. Fedora CoreOS uses a [Fedora CoreOS Config](https://docs.fedoraproject.org/en-US/fedora-coreos/fcct-config/) (FCC) and Flatcar Linux uses a [Container Linux Config](https://github.com/coreos/container-linux-config-transpiler/blob/master/doc/examples.md) (CLC). These define disk partitions, filesystems, systemd units, dropins, config files, mount units, raid arrays, and users.
|
||||
|
||||
Controller and worker instances form a minimal and secure Kubernetes cluster on each platform. Typhoon provides the **snippets** feature to accept Fedora CoreOS Configs or Container Linux Configs to validate and additively merge into instance declarations. This allows advanced host customization and experimentation.
|
||||
|
||||
!!! note
|
||||
Snippets cannot be used to modify an already existing instance, the antithesis of immutable provisioning. Ignition fully declares a system on first boot only.
|
||||
|
||||
!!! danger
|
||||
Container Linux Configs provide powerful host customization abilities. You are responsible for the additional configs defined for hosts.
|
||||
Snippets provide the powerful host customization abilities of Ignition. You are responsible for additional units, configs, files, and conflicts.
|
||||
|
||||
Container Linux Configs (CLCs) declare how a Container Linux instance's disk should be provisioned on first boot from disk. CLCs define disk partitions, filesystems, files, systemd units, dropins, networkd configs, mount units, raid arrays, and users. Typhoon creates controller and worker instances with base Container Linux Configs to create a minimal, secure Kubernetes cluster on each platform.
|
||||
!!! danger
|
||||
Edits to snippets for controller instances can (correctly) cause Terraform to observe a diff (if not otherwise suppressed) and propose destroying and recreating controller(s). Recognize that this is destructive since controllers run etcd and are stateful. See [blue/green](/topics/maintenance/#upgrades) clusters.
|
||||
|
||||
Typhoon AWS, Azure, bare-metal, DigitalOcean, and Google Cloud support CLC *snippets* - valid Container Linux Configs that are validated and additively merged into the Typhoon base config during `terraform plan`. This allows advanced host customizations and experimentation.
|
||||
### Fedora CoreOS
|
||||
|
||||
#### Examples
|
||||
!!! note
|
||||
Fedora CoreOS snippets require `terraform-provider-ct` v0.5+
|
||||
|
||||
Container Linux [docs](https://coreos.com/os/docs/latest/clc-examples.html) show many simple config examples. Ensure a file `/opt/hello` is created with permissions 0644.
|
||||
Define a Fedora CoreOS Config (FCC) ([docs](https://docs.fedoraproject.org/en-US/fedora-coreos/fcct-config/), [config](https://github.com/coreos/fcct/blob/master/docs/configuration-v1_0.md), [examples](https://github.com/coreos/fcct/blob/master/docs/examples.md)) in version control near your Terraform workspace directory (e.g. perhaps in a `snippets` subdirectory). You may organize snippets into multiple files, if desired.
|
||||
|
||||
For example, ensure an `/opt/hello` file is created with permissions 0644.
|
||||
|
||||
```yaml
|
||||
# custom-files
|
||||
variant: fcos
|
||||
version: 1.0.0
|
||||
storage:
|
||||
files:
|
||||
- path: /opt/hello
|
||||
contents:
|
||||
inline: |
|
||||
Hello World
|
||||
mode: 0644
|
||||
```
|
||||
|
||||
Reference the FCC contents by location (e.g. `file("./custom-units.yaml")`). On [AWS](/fedora-coreos/aws/#cluster) or [Google Cloud](/fedora-coreos/google-cloud/#cluster) extend the `controller_snippets` or `worker_snippets` list variables.
|
||||
|
||||
```tf
|
||||
module "nemo" {
|
||||
...
|
||||
|
||||
controller_count = 1
|
||||
worker_count = 2
|
||||
controller_snippets = [
|
||||
file("./custom-files"),
|
||||
file("./custom-units"),
|
||||
]
|
||||
worker_snippets = [
|
||||
file("./custom-files"),
|
||||
file("./custom-units")",
|
||||
]
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||
On [Bare-Metal](/fedora-coreos/bare-metal/#cluster), different FCCs may be used for each node (since hardware may be heterogeneous). Extend the `snippets` map variable by mapping a controller or worker name key to a list of snippets.
|
||||
|
||||
```tf
|
||||
module "mercury" {
|
||||
...
|
||||
snippets = {
|
||||
"node2" = [file("./units/hello.yaml")]
|
||||
"node3" = [
|
||||
file("./units/world.yaml"),
|
||||
file("./units/hello.yaml"),

||||

|

Reference the CLC contents by location (e.g. `file("./custom-units.yaml")`). On [AWS](/cl/aws/#cluster), [Azure](/cl/azure/#cluster), [DigitalOcean](/cl/digital-ocean/#cluster), or [Google Cloud](/cl/google-cloud/#cluster) extend the `controller_clc_snippets` or `worker_clc_snippets` list variables.

||||

|
||||
|
||||
#### Usage
|
||||
|
||||
Write Container Linux Configs *snippets* as files in the repository where you keep Terraform configs for clusters (perhaps in a `clc` or `snippets` subdirectory). You may organize snippets in multiple files as desired, provided they are each valid.
|
||||
|
||||

Most syntax errors in CLCs can be caught during planning. For example, mangle the indentation in one of the CLC files:

```
|
||||
|
||||
Container Linux Configs (and the CoreOS Ignition system) create immutable infrastructure. Disk provisioning is performed only on first boot from disk. That means if you change a snippet used by an instance, Terraform will (correctly) try to destroy and recreate that instance. Be careful!
|
||||
|
||||
!!! danger
|
||||
Destroying and recreating controller instances is destructive! etcd runs on controller instances and stores data there. Do not modify controller snippets. See [blue/green](/topics/maintenance/#upgrades) clusters.
|
||||
|
||||
## Architecture
|
||||
|
||||
Typhoon chooses variables to expose with purpose. If you must customize clusters in ways that aren't supported by input variables, fork Typhoon and maintain a repository with customizations. Reference the repository by changing the username.
