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 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 }

- Method Detail
  - hasCommand
```
public final boolean hasCommand()
```
    For responses, this returns true if the service returned a value for the Command property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - command
```
public final List<String> command()
```
    A string array that specifies the command that the container runs to determine if it's healthy.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasCommand() method.
    
    Returns:
    
    A string array that specifies the command that the container runs to determine if it's healthy.
  - interval
```
public final Integer interval()
```
    The time period (in seconds) between each health check.
    
    Returns:
    
    The time period (in seconds) between each health check.
  - retries
```
public final Integer retries()
```
    The number of times to retry a failed health check before flagging the container unhealthy. The first run of the command does not count as a retry.
    
    Returns:
    
    The number of times to retry a failed health check before flagging the container unhealthy. The first run of the command does not count as a retry.
  - startPeriod
```
public final Integer startPeriod()
```
    The optional grace period (in seconds) to give a container time to bootstrap before the first failed health check counts toward the number of retries.
    
    Returns:
    
    The optional grace period (in seconds) to give a container time to bootstrap before the first failed health check counts toward the number of retries.
  - timeout
```
public final Integer timeout()
```
    The time period (in seconds) to wait for a health check to succeed before counting a failed health check.
    
    Returns:
    
    The time period (in seconds) to wait for a health check to succeed before counting a failed health check.
  - toBuilder

    Overrides:
    
    hashCode in class Object
  - equals

    Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
