Http.WaitForHealthy("https://app.example.com/healthz/db", o => o
  .WithTimeoutSeconds(300)
  .WithIntervalSeconds(5));

Example

Wait for a freshly deployed app to report healthy before swapping a slot into production. Http.WaitForHealthy runs in-process on the build host, so the build image does not need curl.

// Deploy to the staging slot
AppService.DeployFolder("my-web-app", Root / "publish", "my-rg", o => o
  .WithDeploymentSlot("staging"));

// Wait for the staging slot to come up before promoting it
Http.WaitForHealthy("https://my-web-app-staging.azurewebsites.net/healthz", o => o
  .WithTimeoutSeconds(300)
  .WithIntervalSeconds(5));

// Promote staging to production
AppService.SwapSlots("my-web-app", "staging", "my-rg");
