Variables ¶

View Source

var ErrNoDrive = errors.New("no NoCloud drive: attach a cloud-init drive with user-data (fqdn) and network-config")

ErrNoDrive is a machine without a NoCloud drive.

View Source

var ErrNotBaked = errors.New("no " + config.EdgeFile + " in the ISO: this is the release ISO; boot one made with fortressctl bake")

ErrNotBaked is the release ISO booted as it ships: it has no fortress.yml, so it trusts nobody.

Functions ¶

func LoadPolicy ¶

func LoadPolicy(path string) ([]byte, error)

LoadPolicy reads the policy fortressctl apply stored at path. An edge nobody applied a policy to has none: nil, and no error.

func MountSource ¶

func MountSource(dir string) (string, bool)

MountSource reports what device is mounted at dir, if any.

func MountVar ¶

func MountVar(dev string) (string, error)

MountVar mounts the persistent disk at /var, formatting it ext4 if blank. An empty dev uses /dev/vda when it exists and /dev/sda otherwise. State lives in /var/fortressedge, logs in /var/log/fortressedge. Idempotent. The returned path is the device that is mounted.

func Setup ¶

func Setup() error

func StorePolicy ¶

func StorePolicy(path string, b []byte) error

StorePolicy replaces the policy at path whole: a power cut leaves the old one or the new one, never part of either.

func WatchPower ¶

func WatchPower(press func())

WatchPower calls press once when the ACPI power button is pressed. Proxmox Shutdown and Reboot are that button (QMP system_powerdown); Reboot starts the VM again only after it has powered off. The goroutines block in read until the process exits on poweroff.

Types ¶

type Seed ¶

type Seed struct {
	UserData      []byte
	NetworkConfig []byte
	Edge          []byte
}

Seed is the config boot reads: fortress.yml from the ISO, user-data and network-config from the NoCloud drive. The policy is on the /var disk, read once that is mounted.

func FindSeed ¶

func FindSeed() (Seed, error)

FindSeed reads fortress.yml from the initramfs and waits for the NoCloud drive. The drive stays attached: every boot reads it, as cloud-init does, so a change made on the platform (Proxmox's Cloud-Init tab, a Terraform apply) takes effect at the next start.
