Changes AWS CodeDeploy can now detect instances running an outdated revision of your application and automatically update them with the latest revision.
Changes Amazon ECS customers using application and network load balancers can use CodeDeploy BlueGreen hook to invoke a CloudFormation stack update. With this update you can view CloudFormation deployment and target details via existing APIs and use your stack Id to list or delete all deployments associated with the stack.
Changes AWS CodeDeploy now supports tagging for the application and deployment group resources.
Changes Support for Amazon ECS service deployment - AWS CodeDeploy now supports the deployment of Amazon ECS services. An Amazon ECS deployment uses an Elastic Load Balancer, two Amazon ECS target groups, and a listener to reroute production traffic from your Amazon ECS service's original task set to a new replacement task set. The original task set is terminated when the deployment is complete. Success of a deployment can be validated using Lambda functions that are referenced by the deployment. This provides the opportunity to rollback if necessary. You can use the new ECSService, ECSTarget, and ECSTaskSet data types in the updated SDK to create or retrieve an Amazon ECS deployment.
Changes The AWS CodeDeploy API was updated to support DeleteGitHubAccountToken, a new method that deletes a GitHub account connection.
Changes Support for AWS Lambda function deployment - AWS CodeDeploy now supports the deployment of AWS Lambda functions. A Lambda deployment uses a Lambda function alias to shift traffic to a new version. You select a deployment configuration that specifies exactly how traffic shifts to your new version. Success of a deployment can be validated using Lambda functions that are referenced by the deployment. This provides the opportunity to rollback if necessary.
Changes Adds support for specifying Application Load Balancers in deployment groups, for both in-place and blue/green deployments.
Changes AWS CodeDeploy now supports the use of multiple tag groups in a single deployment group (an intersection of tags) to identify the instances for a deployment. When you create or update a deployment group, use the new ec2TagSet and onPremisesTagSet structures to specify up to three groups of tags. Only instances that are identified by at least one tag in each of the tag groups are included in the deployment group.
Changes AWS CodeDeploy has improved how it manages connections to GitHub accounts and repositories. You can now create and store up to 25 connections to GitHub accounts in order to associate AWS CodeDeploy applications with GitHub repositories. Each connection can support multiple repositories. You can create connections to up to 25 different GitHub accounts, or create more than one connection to a single account. The ListGitHubAccountTokenNames command has been introduced to retrieve the names of stored connections to GitHub accounts that you have created. The name of the connection to GitHub used for an AWS CodeDeploy application is also included in the ApplicationInfo structure. Two new fields, lastAttemptedDeployment and lastSuccessfulDeployment, have been added to DeploymentGroupInfo to improve the handling of deployment group information in the AWS CodeDeploy console. Information about these latest deployments can also be retrieved using the GetDeploymentGroup and BatchGetDeployment group requests. Also includes a region update (us-gov-west-1).
Changes This release introduces the previousRevision field in the responses to the GetDeployment and BatchGetDeployments actions. previousRevision provides information about the application revision that was deployed to the deployment group before the most recent successful deployment. Also, the fileExistsBehavior parameter has been added for CreateDeployment action requests. In the past, if the AWS CodeDeploy agent detected files in a target location that weren't part of the application revision from the most recent successful deployment, it would fail the current deployment by default. This new parameter provides options for how the agent handles these files: fail the deployment, retain the content, or overwrite the content.
Changes This release of AWS CodeDeploy introduces support for blue/green deployments. In a blue/green deployment, the current set of instances in a deployment group is replaced by new instances that have the latest application revision installed on them. After traffic is rerouted behind a load balancer to the replacement instances, the original instances can be terminated automatically or kept running for other uses.
Changes CodeDeploy supports IAM Session Arns in addition to IAM User Arns for on premise host authentication.
Changes AWS CodeDeploy now integrates with Amazon CloudWatch alarms, making it possible to stop a deployment if there is a change in the state of a specified alarm for a number of consecutive periods, as specified in the alarm threshold. AWS CodeDeploy also now supports automatically rolling back a deployment if certain conditions are met, such as a deployment failure or an activated alarm.
