Overview ¶

Package hostprovider names the cloud or VPS provider this server runs on, from DMI strings first and a short link-local metadata probe second, and holds the provider-specific steps for opening web ports in a firewall the control plane cannot change.

Types ¶

type Deps ¶

type Deps struct {
	ReadFile func(path string) ([]byte, error)
	// Get performs one GET and returns the status code and a bounded body.
	Get func(ctx context.Context, url string, header http.Header) (int, []byte, error)
}

Deps are the host seams; tests replace both.

func SystemDeps ¶

func SystemDeps() Deps

SystemDeps reads the real host and uses a one second metadata timeout.

type Guidance ¶

type Guidance struct {
	ID      ID         `json:"id"`
	Name    string     `json:"name"`
	Source  string     `json:"source"`
	DocsURL string     `json:"docs_url"`
	Ports   []PortRule `json:"ports"`
	Steps   []string   `json:"steps"`
	Note    string     `json:"note,omitempty"`
}

Guidance is the exact manual procedure for one provider's firewall.

func Detect ¶

func Detect(ctx context.Context, d Deps) (Guidance, bool)

Detect returns the provider guidance for this host, or false when none is recognised.

func For ¶

func For(id ID, source string) Guidance

For returns the guidance for id, tagged with how it was detected.

type ID ¶

type ID string

ID names a provider.

const (
	DigitalOcean ID = "digitalocean"
	AWS          ID = "aws"
	GCP          ID = "gcp"
	Hetzner      ID = "hetzner"
	Azure        ID = "azure"
	Oracle       ID = "oracle"
	Vultr        ID = "vultr"
	Linode       ID = "linode"
)

Provider IDs.

type PortRule ¶

type PortRule struct {
	Port     int    `json:"port"`
	Protocol string `json:"protocol"`
	Source   string `json:"source"`
}

PortRule is one inbound rule to create.
