Hi! Can you paste the health check from your compose file?

Priya Nair Team Aurora · 10:11 a.m. · #9

healthcheck:
  test: ["CMD", "curl", "-f", "http://localhost:8080/health"]
  interval: 10s
  retries: 3

Our server listens on 3000 now. We changed it on Friday night.

That's it. The health check still calls port 8080, so it fails and Docker keeps restarting the container. Point it at 3000 and redeploy.

Meet at our table: Table 12.

Redeployed. It's been up for 20 minutes with no restarts.

Repaired the deployment configuration: the health check pointed at the wrong port, so the container kept being restarted.

-      test: ["CMD", "curl", "-f", "http://localhost:8080/health"]
+      test: ["CMD", "curl", "-f", "http://localhost:3000/health"]
