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

  4. 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.

  6. Sam Okafor Team Maple · 10:15 a.m. · #11

    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.

  8. Priya Nair Team Aurora · 10:39 a.m. · #13

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

Outcome

Submitted by Sam Okafor, Team Maple · 10:41 a.m.

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

Evidence: Code diff

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