A Pulumi package for managing Kubernetes proxies during provisioning.
Kubernetes Proxy Pulumi Provider
A [Pulumi] provider that proxies a port on the host to a port on a pod in the cluster during provisioning.
Warning: The way this fits into the Pulumi model is sketchy. It might break in future Pulumi releases. Use at your own risk!
This can be useful to use Pulumi to provision services that run within the cluster that are not publicly accessible, like a database.
To provision a PostgreSQL database running in Kubernetes:
import pulumi_kubernetes_proxy as k8s_proxy # Hardcode a port that is likely to be free. This needs to be stable (i.e., we # can't just let the kernel allocate a free port) so that Pulumi doesn't # perpetually show a diff in the PostgreSQL provider. PORT = 32123 eks_cluster = eks.Cluster(...) k8s_proxy.Provider( "postgresql-proxy", kubeconfig=eks_cluster.kubeconfig, host_port=PORT, remote_port=5432, # Target the PostgreSQL port. namespace="default", pod_selector="workload=postgresql", ) provider = postgresql.Provider( base_name, host="localhost", port=PORT, connect_timeout=10, database="db", username="user", password="pass", opts=pulumi.ResourceOptions(depends_on=[rds_proxy_provider]), )
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
