Why did the health check fail?

Looks like it just timed out. When I increased the healthcheck duration to 5 mins, a couple of the subsequent builds took too long to deploy successfully, so had to redeploy them. Avg deploy time is ~1 minute.

Looks like? I would appreciate it if you could tell me the reason as printed by the health check logs.

Here's healthcheck status from the buildlogs

Attempt #1 failed with service unavailable. Continuing to retry for 49s
Attempt #2 failed with service unavailable. Continuing to retry for 38s
Attempt #3 failed with service unavailable. Continuing to retry for 25s
Attempt #4 failed with service unavailable. Continuing to retry for 11s

1/1 replicas never became healthy!
Healthcheck failed!

But here are the deploy logs which basically state that the server was up

loaded configuration
[GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production.
- using env:    export GIN_MODE=release
- using code:    gin.SetMode(gin.ReleaseMode)
[GIN-debug] GET    /health                   --> reply_rocket/internal/handler.HealthCheck (6 handlers)

Also, the same commits which are facing this healthcheck issue on production are successfully deploying on staging without any redeployments.

Please have your GIN server listen on the PORT environment variable.

I'm pretty sure its the same, haven't changed anything.
The same commit when redeployed (without any changes to env) doesn't fail again.

Here's a log from a successful deployment.

I'm pretty sure its the same

Please check, and if needed make the necessary changes.

Checked, its the same.

Is your GIN server listening on the PORT environment variable? (y/N)

y

Please show the applicable code.

Here's the server starting:

        if err := endless.ListenAndServe(fmt.Sprintf(":%s", cfg.Port), r); err != nil {
            lg.Error().Err(err).Msg("server closed")
        }

Here's how cfg.Port references the env

type Server struct {
    Port        string            `envconfig:"PORT,optional" default:"8080"`

What is your PORT service variable set to?

8080

ttempt #8 failed with service unavailable. Continuing to retry for 27s
