Pulumi's 2.0 release introduces enhanced support for Node.js, Python, .NET, and Go, along with significant improvements to Kubernetes and other cloud resource providers. The update includes refined management capabilities for Kubernetes clusters and application workloads, offering users multiple ways to provision and manage workloads through YAML manifests, Helm charts, operators, and direct API access. The pulumi/kubernetes package now supports Go and .NET, alongside enhanced features like the latest Kubernetes v1.18 release and warnings for deprecated apiVersions. Pulumi expands its support for managed Kubernetes clusters, including additional security group options and envelope-encrypted secrets. The update also facilitates alternative authentication methods, and the generation of kubeconfig files for specific IAM users or roles. Pulumi encourages user feedback to further enhance the Kubernetes experience and offers various resources like PulumiTV and Community Slack for learning and engagement.
