Deployment resource state does not update

[soujiro32167]

What happened?

Using a kubernetes provider with renderYamlToDirectory, I want to create a deployment and configmap.

The resources get created successfully. After a second pulumi up, no changes are observed.

However, after updating the deployment, the pulumi state will not update. Updating the configmap works fine

To reproduce:

1. Run the reproducer file with a clean stack: pulumi up -s repro
2. Update the deployment - containerPort: 9090
3. pulumi up -s repro --diff shows the diff correctly
4. Click yes to apply the changes
5. pulumi up -s repro --diff shows the same diff, even though the change was already applied

Note: the yaml yamls/apps_v1-deployment-myns-my-deployment.yaml gets updated correctly

Example

import * as k8s from "@pulumi/kubernetes"
import * as pulumi from "@pulumi/pulumi"

const provider = new k8s.Provider("k8s", {
    renderYamlToDirectory: 'yamls',
    namespace: 'myns'
})

const configMap = new k8s.core.v1.ConfigMap("my-configmap", {
    metadata: {
        name: "my-configmap",
    },
    data: {
        "key1": "value1",
        "key2": "value2",
    },
}, {provider})

const deployment = new k8s.apps.v1.Deployment("my-deployment", {
    metadata: {
        name: "my-deployment",
    },
    spec: {
        replicas: 1,
        selector: {
            matchLabels: {
                app: "my-deployment",
            },
        },
        template: {
            metadata: {
                labels: {
                    app: "my-deployment",
                },
            },
            spec: {
                containers: [
                    {
                        name: "my-deployment",
                        image: "nginx",
                        ports: [
                            {
                                containerPort: 8080,
                            },
                        ],
                    },
                ],
            },
        },
    },
}, {provider})

Thanks for reporting this issue @soujiro32167. I am able to reproduce this. Note that the same issue also exists for ConfigMaps if we set CMs to be mutable within our k8s provider setup. The issue doesn't exist for CMs in the repro, since our provider is doing a replacement, which goes through a different flow for saving state compared to an update flow.

The bug most likely is being triggered here:

pulumi-kubernetes/provider/pkg/provider/provider.go

Line 2365 in 41b0d90

obj := checkpointObject(newInputs, oldLive, newResInputs, initialAPIVersion, fieldManager)

We should store newInputs instead of oldLive similar to what we do in the Create flow (ref:

pulumi-kubernetes/provider/pkg/provider/provider.go

Line 1865 in 41b0d90

obj := checkpointObject(newInputs, newInputs, newResInputs, initialAPIVersion, fieldManager)

).
