[SOLVED] Why does my Rocket health endpoint return 404 not found?

Why does my Rocket health endpoint return 404 not found?

I am implementing health check endpoint for my Rocket API like this:

rocket_healthz = "0.2.0"

rocket_healthz::healthz!();

#[launch]
fn rocket() -> _ {
    rocket::build()
        .mount("/actuator/health", routes![healthz])
}

but when I access the health endpoint using this command:

curl http://127.0.0.1:11014/actuator/health

shows result like this:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <title>404 Not Found</title>
</head>
<body align="center">
    <div role="main" align="center">
        <h1>404: Not Found</h1>
        <p>The requested resource could not be found.</p>
        <hr />
    </div>
    <div role="contentinfo" align="center">
        <small>Rocket</small>
    </div>
</body>

Where am I going wrong? What should I do to fix this problem?

Solution

From the documentation, it looks like it adds the /healthz part itself. So as written, calling the endpoint /actuator/health/healthz should work.

I do not see a way for you to customize the route if you wanted /health instead of /healthz.
