Overview
When making an API call, you may pass MinimumHealthyHosts data as a hash:
{
type: "HOST_COUNT", # accepts HOST_COUNT, FLEET_PERCENT
value: 1,
}

Instance Attribute Details
#type ⇒ String
The minimum healthy instance type:
HOST_COUNT
: The minimum number of healthy instances as an absolute value.FLEET_PERCENT
: The minimum number of healthy instances as a percentage of the total number of instances in the deployment.
In an example of nine instances, 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 instances at a time. The deployment is successful if four or more instances are deployed to successfully. Otherwise, the deployment fails.
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.
