Database Management - fluxcd/flux2

The database schema of Flux is not documented, and the code does not contain a reference to the database schema. It is likely that Flux does not use a relational database, but rather stores its data in a configuration file or in the Kubernetes cluster itself.

You may wish to refer to the official Flux documentation for further details.

How do I query the database?

Flux uses a database to store the state of the cluster and to track changes. The database is used by Flux to ensure that changes are applied correctly and that the cluster remains in a consistent state.

You can query the Flux database using the flux command-line tool. You can use the flux get command to view the inventory of resources that are managed by Flux.

Here’s an example of how to query the database using the flux get command:

flux get

To get information about all of the resources in the Flux database, you can use the flux get all command. This command will output a list of all resources that are tracked by Flux.

flux get all

You can also use the flux get command to query specific resources. For example, to view information about the resource “deployment.apps/nginx-deployment” you would use the following command:

flux get deployment.apps/nginx-deployment

You can also use the flux get command to query specific resources. To view information about the resource “deployment.apps/nginx-deployment” you would use the following command:

flux get deployment.apps/nginx-deployment

To get a summary of the resources tracked by Flux, you can use the flux stats command.

flux stats

This will output a summary of the resources that are tracked by Flux, including the number of resources, the number of resources that are in sync, and the number of resources that are out of sync.

You can also use the flux get all command to list the resource metadata that Flux is tracking. The flux get command works by reading from the Flux database.

Here’s an example of how to query the database using the flux get all command:

package main

import (
    "github.com/fluxcd/flux2/v2/internal/build"
    "github.com/fluxcd/flux2/v2/internal/object"
    kustomizev1 "github.com/fluxcd/flux2/v2/pkg/apis/kustomize/v1"
)

func main() {
    // Load the Flux inventory.
    inv := &kustomizev1.ResourceInventory{}

    // List the metadata of the resources in the Flux database.
    metas, err := build.ListMetaInInventory(inv)
    if err != nil {
        // Handle error.
    }

    // Print the metadata of the resources in the Flux database.
    for _, meta := range metas {
        // Print the metadata of the resource.
    }
}
