Install/Upgrade

kapp is recommended to install/upgrade the Service Bindings CRDs and operator.

If upgrading from a release not installed with kapp, first remove the current install.

Then deploy Service Bindings:

kapp deploy -a service-bindings -f https://github.com/vmware-tanzu/servicebinding/releases/download/v0.9.4/service-bindings-0.9.4.yaml

If you are unable to use kapp, service-bindings-0.9.4.yaml can be applied via tools like kubectl, but it will be harder to uninstall and upgrade.

Advanced installs

For users who need to install into an air-gapped cluster, or wish to limit their dependence on public image registries, an imgpkg bundle is available. For this install flow Carvel kapp, imgpkg and kbld are required.

Download the bundle to a location that has access to your image registry and cluster:

curl -L https://github.com/vmware-tanzu/servicebinding/releases/download/v0.9.4/service-bindings-bundle-0.9.4.tar -o service-bindings-bundle-0.9.4.tar

Relocate the bundle's images to your registry:

imgpkg copy --tar service-bindings-bundle-0.9.4.tar --to-repo <your-image-repository>

Pull the config files from the bundle:

mkdir bundle
imgpkg pull --bundle <your-image-repository> --output bundle

Finally, deploy Service Binding to your cluster:

kapp deploy -a service-bindings -f <(kbld -f ./bundle/config/service-bindings.yaml -f ./bundle/.imgpkg/images.yml)

The Carvel docs have more information about deploying to air-gapped environments.

kapp-controller managed installs

Preview support for kapp-controller with a Package definition in the service-bindings-package-0.9.3.yaml asset. Please see the Carvel docs for how to install a package on a cluster.

Uninstall

To remove service bindings from your cluster:

kapp delete -a service-bindings
