The Convox deployment process depends on application Health Checks to determine success.

If the Process exposes a port is it considered healthy after it passes a certain number of HTTP health checks.

Definition

services:
  web:
    health:
      grace: 5
      interval: 5
      path: /health
      timeout: 3

Options

Common Failures

• The cluster does not have sufficient memory or CPU resources available to start a new process
• The cluster does not have sufficient instances where a new process port is not already reserved by an older release
• A process crashes immediately after starting due to a problem in the latest code
• A process takes too long to initialize its server and therefore fails a network health check
• Returning a status code outside the acceptable (200-399,401) range
