AliasProps Struct
Properties for a new Lambda alias.
Example
ts
const lambdaCode = lambda.Code.fromCfnParameters();
const func = new lambda.Function(this, 'Lambda', {
code: lambdaCode,
handler: 'index.handler',
runtime: lambda.Runtime.NODEJS_LATEST,
});
// used to make sure each CDK synthesis produces a different Version
const version = func.currentVersion;
const alias = new lambda.Alias(this, 'LambdaAlias', {
aliasName: 'Prod',
version,
});
new codedeploy.LambdaDeploymentGroup(this, 'DeploymentGroup', {
alias,
deploymentConfig: codedeploy.LambdaDeploymentConfig.LINEAR_10PERCENT_EVERY_1MINUTE,
});
Properties
additionalVersionsVersionWeight[]additional_versionstyping.List[VersionWeight]additionalVersionsList<VersionWeight>AdditionalVersionsVersionWeight[]AdditionalVersions*[]VersionWeight= No additional versions#Additional versions with individual weights this alias points to.
notes
Individual additional version weights specified here should add up to (less than) one. All remaining weight is routed to the default version.
For example, the config is
version: "1" additionalVersions: [{ version: "2", weight: 0.05 }]
Then 5% of traffic will be routed to function version 2, while the remaining 95% of traffic will be routed to function version 1.
