Load Balancer Healthchecks

Load balancer healthchecks are configured in Docker services and can determine when a container is not healthy to receive traffic.

Configuring

Healthchecks are configured per service and are tested at container runtime.

Viewing

To view load balancer healthcheck logs:

1. Navigate to the "loadbalancer" service details page.

2. Click "Logs" to view the logs.

   

3. Inspect the logs for the behaviour of healthchecks.
   The following example is what a failing healthcheck could look like.

   

Docker Healthchecks

Docker healthchecks are defined in Dockerfile and will run when the container is started. However, the outcome of a Docker healthcheck has limited visibility in MedStack Control. The result of a failing healthcheck may be published as a task error on the service details page.
