DeploymentConfig

Source: src/AWS/CodeDeploy/DeploymentConfig.ts

A custom AWS CodeDeploy deployment configuration — the rules for how traffic shifts during a deployment (canary/linear traffic routing for Lambda/ECS, minimum-healthy-hosts and zonal rollout for Server). Deployment configurations are immutable: any change replaces the configuration.

Creating a Deployment Config

Lambda Canary Config

const config = yield* CodeDeploy.DeploymentConfig("canary", {
  computePlatform: "Lambda",
  trafficRoutingConfig: {
    type: "TimeBasedCanary",
    timeBasedCanary: { canaryPercentage: 10, canaryInterval: 5 },
  },
});

Server Config with Minimum Healthy Hosts

const config = yield* CodeDeploy.DeploymentConfig("half-fleet", {
  computePlatform: "Server",
  minimumHealthyHosts: { type: "FLEET_PERCENT", value: 50 },
});
