Uninstall Crossplane

On this page

This document is for an older version of Crossplane.

This document applies to Crossplane version v1.16 and not to the latest release v1.18.

Warning

Resources created by Crossplane aren’t deleted if Crossplane isn’t uninstalled in order.

This can leave cloud resources running, requiring manual deletion.

Ordered Crossplane uninstall

Most Crossplane resources have dependencies on other Crossplane resources.

For example, a managed resource is dependent on the provider.

Failure to delete Crossplane resources in order may prevent Crossplane from deleting provisioned external resources.

Removing Crossplane resources should happen in the following order:

Remove all composite resource definitions
Remove all remaining managed resources
Remove all providers

Deleting the Crossplane pod removes remaining Crossplane components like claims.

Tip

Collect an inventory of all external resources with kubectl get managed.

Depending on the size of the Kubernetes API server and number of resources, this command may take minutes to return.

Remove composite resource definitions

Removing installed composite resource definitions removes any composite resources defined by the composite resource definition and the managed resourced they created.

View the installed composite resource definitions with kubectl get xrd.

1kubectl get xrd
2NAME                                                ESTABLISHED   OFFERED   AGE

Delete the composite resource definitions with kubectl delete xrd.

1kubectl delete xrd compositepostgresqlinstances.database.example.org

Remove managed resources

Manually delete any managed resources manually created.

Use kubectl get managed to view remaining managed resources.

1kubectl get managed
2NAME                                                   READY   SYNCED   EXTERNAL-NAME                 AGE
3bucket.s3.aws.upbound.io/crossplane-bucket-867737b10   True    True     crossplane-bucket-867737b10   8h

Use kubectl delete to remove the resources.

1kubectl delete bucket.s3.aws.upbound.io/crossplane-bucket-867737b10

Remove Crossplane providers

List the installed providers with kubectl get providers.

1kubectl get providers
2NAME                   INSTALLED   HEALTHY   PACKAGE                                        AGE
3upbound-provider-aws   True        True      xpkg.upbound.io/upbound/provider-aws:v0.27.0   8h

Remove the installed providers with kubectl delete provider.

1kubectl delete provider upbound-provider-aws

Uninstall the Crossplane deployment

Uninstall Crossplane using Helm with helm uninstall

1helm uninstall crossplane --namespace crossplane-system

Verify Helm removed the Crossplane pods with kubectl get pods

1kubectl get pods -n crossplane-system
2No resources found in crossplane-system namespace.

Delete the Crossplane namespace

When Helm installs Crossplane it creates the crossplane-system namespace. Helm doesn’t uninstall this namespace with helm uninstall.

Manually delete the Crossplane namespace with kubectl delete namespace.

1kubectl delete namespace crossplane-system

Verify Kubernetes removed the namespace with kubectl get namespaces

1kubectl get namespace
