Health checks verify that your application is functioning correctly and ready to handle incoming requests. By checking startup readiness and ongoing liveness, Magic Containers can prevent issues before they impact your users.

​
Health check types

Magic Containers offers three types of health checks:
  • Startup - Verifies the application has successfully started. No requests are routed until this check passes.
  • Readiness - Ensures the application is ready to handle incoming requests. We strongly recommend enabling this check to avoid failed requests.
  • Liveness - Confirms the application is actively running without problems.

​
Configuration

1

Enable health checks

Click the checkbox for each health check type you want to enable (Startup, Readiness, Liveness).
4

Configure the check method

Select either HTTP GET or TCP from the dropdown:HTTP GET - Provide the path and port for the HTTP request.
TCP - Specify the port for the TCP health check.
We strongly recommend enabling at least the Readiness health check to minimize failed requests and ensure a smoother user experience.
