New and updated cloud providers
EKS Pulumi Package supports more options for managed node groups
As the AWS team has improved the Elastic Kubernetes Service (EKS), they’ve added additional options, particularly for managed node groups, that haven’t been available in the EKS Pulumi Package. We’ve updated the package to add these missing options.

New resources in the Azure Native provider
We shipped 2 new versions of the Azure Native provider (1.20.0 through 1.21.0) that collectively added 8 new resources that you can manage with the Azure Native provider, including core networking and IoT security resources.
Pulumi CLI and core technologies
In this milestone, we shipped Pulumi versions 3.9.0 through 3.10.1. The full list of changes in each version is available in the changelog; read on to learn about some of the biggest changes.
Methods for Pulumi Component Packages
Pulumi Components often have methods that provide additional functionality associated with an instance of a component. Previously, when authoring a Pulumi Component Package, you couldn’t make a component’s methods available in all languages. Now, with updates to the Pulumi Packages schema and Provider interface, you can! We’ll have a dedicated blog post out soon with more details on how to use methods in your Pulumi Component Package.

dependsOn now works for Pulumi Component Packages, and more
The dependsOn option creates a list of explicit dependencies between resources, which can be useful when you need to explicity specify additional dependencies that Pulumi doesn’t know about but must still respect. Previously, dependsOn worked differently depending on the language your Pulumi code was written in or when referencing a component inside a Pulumi Component Package. Now, depending on a Pulumi Component Package’s component will always wait on all of that component’s children, regardless of language. Additionally, you can now pass Inputs and Outputs to dependsOn, which can be especially useful in Kubernetes and Helm workflows where you need to depend on the output of a resource created by a Helm chart.
To see this work in action, check out the Staged App Rollout Gated by Prometheus Checks example, where we create a staged rollout (from 3-replica canary -> 10-replica staging) gated by confirming that the P90 response time reported by Prometheus is less than some amount. The relevant code is the last line of this snippet, which lets your Kubernetes deployment depend on a Prometheus resource:
const p8sService = prometheus.getResource("v1/Service", "p8s-prometheus-server");
const p8sDeployment = prometheus.getResource(
"extensions/v1beta1/Deployment",
"p8s-prometheus-server",
);
const localPort = 9090;
const forwarderHandle = util.forwardPrometheusService(p8sService, p8sDeployment, {
localPort,
});
// Canary ring. Replicate instrumented Pod 3 times.
const canary = new k8s.apps.v1beta1.Deployment(
"canary-example-app",
{ spec: { replicas: 1, template: instrumentedPod } },
{ dependsOn: p8sDeployment },
);

Aliases can now be used with providers
Pulumi has historically enabled you to alias resources, which can help with scenarios where you want to change a resource’s name without causing a delete and replace of that resource. Now, you can also alias providers, which can make it easier to refactor stacks and code over time. In the example below, an AWS provider instance is created with the alias “newName”:
import * as aws from "@pulumi/aws";
const providerName = "newName";
const awsProvider = new aws.Provider(providerName, {
region: "us-west-2",
}, { aliases: [{ name: "oldName" }]});
const bucket = new aws.s3.Bucket("my-bucket", {}, { provider: awsProvider });
export const bucketName = bucket.id;

Azure Native resources now link to the Azure Portal
For popular cloud providers like Pulumi AWS and Pulumi Azure Classic, the Pulumi Service contains convenient links from the Resources tab directly to the resource’s management page in the cloud provider console. Now, resources you manage using the Pulumi Azure Native Provider provide these convenient links to the Azure Portal.
