pub struct CanopyClient { /* private fields */ }Expand description
HTTP client with auth configured for talking to a canopy server.
Tries two auth paths in order of preference:
- Tailscale: if the canopy tailnet endpoint is reachable, plain HTTPS works (auth is implicit via tailscale identity).
- mTLS: a fresh self-signed cert from the device key, short-lived
([
CERT_VALIDITY_DAYS]); for long-running daemons,Self::renewshould tick onCERT_RENEW_AFTERto swap in a fresh cert before expiry.
Self::refresh re-probes tailscale and swaps modes on reload.
Implementations§
Source§impl CanopyClient
impl CanopyClient
Sourcepub async fn new(
tamanu_version: impl Into<String>,
device_key_pem: Option<&str>,
) -> Result<Option<Self>>
pub async fn new( tamanu_version: impl Into<String>, device_key_pem: Option<&str>, ) -> Result<Option<Self>>
Build a canopy client, preferring tailscale and falling back to mTLS.
Probes the tailscale canopy endpoint first; if reachable, uses it.
Otherwise, if a device key PEM is provided, builds an mTLS client.
Returns Ok(None) if neither path is available.
tamanu_version is the version of the Tamanu install this client
speaks for; sent on every request via the X-Version header.
Sourcepub async fn is_tailscale(&self) -> bool
pub async fn is_tailscale(&self) -> bool
Returns true if the client is currently using the tailscale path.
Sourcepub async fn refresh(&self) -> Result<()>
pub async fn refresh(&self) -> Result<()>
Re-probe tailscale and swap modes if the picture has changed.
Intended to be called when the daemon receives a reload signal.
Sourcepub async fn renew(&self) -> Result<()>
pub async fn renew(&self) -> Result<()>
Rebuild the underlying HTTP client with a fresh certificate.
No-op in tailscale mode (no cert to rotate). In mTLS mode, atomically replaces the live client; in-flight requests continue with the old client until they complete.
Sourcepub async fn post_status(
&self,
base_url: &Url,
server_id: &str,
payload: &Value,
) -> Result<()>
pub async fn post_status( &self, base_url: &Url, server_id: &str, payload: &Value, ) -> Result<()>
POST a status snapshot to the canopy server.
In tailscale mode, base_url is ignored and a {TAILSCALE_URL}/public/status/{server_id}
URL is used. In mTLS mode, posts to {base_url}/status/{server_id}.
The payload is free-form JSON; the canopy /status contract reserves the
top-level healthy: bool and health: [] keys. The body is gzip-encoded
with Content-Encoding: gzip.
Sourcepub async fn post_event(
&self,
base_url: &Url,
event: NewEvent<'_>,
) -> Result<()>
pub async fn post_event( &self, base_url: &Url, event: NewEvent<'_>, ) -> Result<()>
POST an event to the canopy server.
In tailscale mode, base_url is ignored and TAILSCALE_URL is used.
In mTLS mode, posts to {base_url}/events.
