ERROR (Mrsk::Utils::HealthcheckPoller::HealthcheckError): Exception while executing on host x.x.x.x: container not ready (unhealthy)

Hi!

I read the similar discussion but my issue is different. I believe my app is coming up correctly but it just doesn't tell MRSK.
Rails 7.0.4. App builds fine on my local.

Here is my error:

` INFO container not ready (unhealthy), retrying in 7s (attempt 7/7)...

I tried putting
get "up" => "rails/health#show", as: :rails_health_check
in my routes.rb but no help.

I know I missed something stupid but I can't see it.

(Btw, I think the 404 is from traefik.)

Thanks!

I see you added route to Rails 6 app. Did you also create the controller and action as well?

Alternatively, do you have any other static page like an /about page? If so, you could configure your docker healthcheck to use that in your config/deploy.yml file.

Thanks. As I said above, it's a rails 7.0.4 app. But I'll try your idea.

Thanks again!

@Jberczel I just changed my healtcheck to / and everything works now. Thanks!
