ContainerHealthCheck
Instructions on when and how to check the health of a support container in a container fleet. These properties override any Docker health checks that are set in the container image. For more information on container health checks, see HealthCheck command in the Amazon Elastic Container Service API. Game server containers don't have a health check parameter; Amazon GameLift Servers automatically handles health checks for these containers.
The following example instructs the container to initiate a health check command every 60 seconds and wait 10 seconds for it to succeed. If it fails, retry the command 3 times before flagging the container as unhealthy. It also tells the container to wait 100 seconds after launch before counting failed health checks.
{"Command": [ "CMD-SHELL", "ps cax | grep "processmanager" || exit 1" ], "Interval":
60, "Timeout": 10, "Retries": 3, "StartPeriod": 100 }
