Resource Discovery

A cross-service inventory engine that walks your emulated compute, networking, storage, database, serverless, and Databricks resources and answers the real cloud discovery APIs: Resource Explorer 2 + Resource Groups Tagging API (AWS), Resource Graph (Azure), and Cloud Asset Inventory (GCP).

Every provider auto-wires a ResourceDiscovery engine over its core drivers, so anything you create through those services is immediately discoverable — no separate registration step.

Use the real SDK (recommended)

import (
    "github.com/aws/aws-sdk-go-v2/service/resourceexplorer2"
    "github.com/stackshy/cloudemu"
    awsserver "github.com/stackshy/cloudemu/server/aws"
)

cloud := cloudemu.NewAWS()
ts := httptest.NewServer(awsserver.New(awsserver.Drivers{
    EC2: cloud.EC2, VPC: cloud.VPC, S3: cloud.S3,
    ResourceDiscovery: cloud.ResourceDiscovery,
    AccountID:         "123456789012",
    Region:            "us-east-1",
}))

client := resourceexplorer2.NewFromConfig(cfg, func(o *resourceexplorer2.Options) {
    o.BaseEndpoint = aws.String(ts.URL)
})

client.Search(ctx, &resourceexplorer2.SearchInput{
    QueryString: aws.String("service:s3 tag.env:prod"),
})

Wire the engine into azureserver.Drivers{ResourceDiscovery: …, SubscriptionID: …} or gcpserver.Drivers{ResourceDiscovery: …, ProjectID: …} for the Azure and GCP equivalents.

Operations supported via SDK-compat

AWS Resource Explorer 2: CreateView, DeleteView, ListViews, GetView, Search, ListResources, ListIndexes, GetIndex. Query filters: service:<name>, tag.<key>:<value>, region:<name>.

AWS Resource Groups Tagging API: GetResources (with ResourceTypeFilters + TagFilters), GetTagKeys, GetTagValues, TagResources, UntagResources.

Azure Resource Graph: POST /resources, POST /resourcesHistory, GET /operations. A KQL subset over the Resources table: where type == … / in~ (…), where location == …, where tags['k'] == …, and | limit / | take.

GCP Cloud Asset Inventory: searchAllResources, searchAllIamPolicies, exportAssets, batchGetAssetsHistory, assets.list, and feed CRUD (Create/List/Get/Patch/Delete). Filters: service:, assetType:, location:, labels.<k>:<v>.

What it inventories

The engine reads live state from the service drivers and emits normalized, cross-cloud resource records:

Alternative: Portable Go API

Query the engine directly, without an SDK:

import "github.com/stackshy/cloudemu/resourcediscovery"

all, _ := aws.ResourceDiscovery.ListAll(ctx)

results, _ := aws.ResourceDiscovery.List(ctx, resourcediscovery.Query{
    Services: []string{"compute"},
    Type:     "Instance",
    Region:   "us-east-1",
    Tags:     map[string]string{"env": "prod"},
})

keys, _ := aws.ResourceDiscovery.GetTagKeys(ctx)
