Plugin overviews

There are 48 plugins currently:

1. Kubernetes Ingestor - - this plugin is a catalog entity provider which creates catalog entities directly from kubernetes resources. It has the ability to ingest by default all standard k8s workload types, allows supplying custom GVKs, and has the ability to auto-ingest all crossplane claims and KRO instances automatically as components. There are numerous annotations which can be put on the kubernetes workloads to influence the creation of the component in backstage. It also supports creating backstage templates and registers them in the catalog for every XRD in your cluster for the Claim resource type.

2. Crossplane Resources Frontend - - this is a frontend plugin which provides visibility into the crossplane claim, composite resource and managed resources associated with a component. This relies heavily on system generated annotations from the Kubernetes Ingestor but technically does not require it if you add all the needed annotations manually. The plugin exposes general data, provides a YAML viewer for each resource including the ability to copy to clipboard the content or download the yaml file. It also supports viewing the events related to a specific resource and includes a graph view of the resources related to a claim.

3. Crossplane Resources Backend - - This plugin implements the permission framework elements for the crossplane frontend plugin and provides necessary backend services.

4. Crossplane Common - - This is a shared common library between the frontend and backend crossplane plugins where the permission definitions reside. This is not added into a backstage instance directly, rather it is a dependency of both of the other plugins.

5. ScaleOps Frontend - - this is a frontend plugin which displays cost optimization data from ScaleOps for Kubernetes workloads on your component. It shows potential and realized savings, resource recommendations, and provides links to the ScaleOps dashboard.

6. ScaleOps Backend - - this backend plugin provides secure server-side authentication with ScaleOps, API proxying for the frontend plugin, and exposes 5 entity-centric MCP actions for AI agents and automation tools to query cost optimization data, recommendations, network usage, and policy definitions.

7. Entity Scaffolder Content - - This allows embedding a tab with scaffolder templates on a component. This can also populate the list of templates and data in the templates based on the context from which it is run.

8. Devpod Plugin - - this plugin adds a grid item on the overview tab of components allowing for a "Open in Devpod" button. It supports allowing the user to choose the IDE it should open with, and also provides the CLI command the user could run to open it up from the command line.

9. Scaffolder Actions - - this is a package of multiple scaffolder actions:

• terasky:claim-template - This action converts input parameters into a kubernetes yaml manifest for the crossplane claim and writes it to the filesystem of the action based on the format "<cluster>/<namespace>/<kind>/<name>.yaml"
• terasky:crd-template - This action converts input parameters into a kubernetes yaml manifest for the Kubernetes Custom Resource and writes it to the filesystem of the action based on the format "<cluster>/<namespace>/<kind>/<name>.yaml"
• terasky:catalog-info-cleaner - This action takes a backstage entity and cleans up runtime information and then outputs as a catalog-info.yaml file on the filesystem of the action the cleaned up manifest.
