NAME

Paws::CodeDeploy::MinimumHealthyHosts

USAGE

This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::CodeDeploy::MinimumHealthyHosts object:

  $service_obj->Method(Att1 => { Type => $value, ..., Value => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::CodeDeploy::MinimumHealthyHosts object:

  $result = $service_obj->Method(...);
  $result->Att1->Type

DESCRIPTION

Information about minimum healthy instance.

ATTRIBUTES

Type => Str

  The minimum healthy instance type:
  • HOST_COUNT: The minimum number of healthy instance as an absolute value.

  • FLEET_PERCENT: The minimum number of healthy instance as a percentage of the total number of instance in the deployment.

In an example of nine instance, if a HOST_COUNT of six is specified, deploy to up to three instances at a time. The deployment is successful if six or more instances are deployed to successfully. Otherwise, the deployment fails. If a FLEET_PERCENT of 40 is specified, deploy to up to five instance at a time. The deployment is successful if four or more instance are deployed to successfully. Otherwise, the deployment fails.

In a call to the GetDeploymentConfig, CodeDeployDefault.OneAtATime returns a minimum healthy instance type of MOST_CONCURRENCY and a value of 1. This means a deployment to only one instance at a time. (You cannot set the type to MOST_CONCURRENCY, only to HOST_COUNT or FLEET_PERCENT.) In addition, with CodeDeployDefault.OneAtATime, AWS CodeDeploy attempts to ensure that all instances but one are kept in a healthy state during the deployment. Although this allows one instance at a time to be taken offline for a new deployment, it also means that if the deployment to the last instance fails, the overall deployment is still successful.

For more information, see AWS CodeDeploy Instance Health (https://docs.aws.amazon.com/codedeploy/latest/userguide/instances-health.html) in the AWS CodeDeploy User Guide.

Value => Int

  The minimum healthy instance value.
