Struct aws_sdk_codedeploy::model::MinimumHealthyHosts

#[non_exhaustive]
pub struct MinimumHealthyHosts { /* private fields */ }

Information about minimum healthy instance.

Implementations

impl MinimumHealthyHosts

pub fn type(&self) -> Option<&MinimumHealthyHostsType>

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.

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, 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 CodeDeploy Instance Health in the CodeDeploy User Guide.

pub fn value(&self) -> i32

impl MinimumHealthyHosts

pub fn builder() -> Builder

Trait Implementations

impl Clone for MinimumHealthyHosts

fn clone(&self) -> MinimumHealthyHosts

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MinimumHealthyHosts

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<MinimumHealthyHosts> for MinimumHealthyHosts

fn eq(&self, other: &MinimumHealthyHosts) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
