Development Guide

Technology stack required for development

Build

make

Run locally

You need an active session open to a kubernetes cluster.

Optionally, run kind and deploy kuadrant deps

make local-env-setup

Then, run the operator locally

make run

Deploy the operator in a deployment object

make local-setup

List of tasks done by the command above:

  • Create local cluster using kind
  • Build kuadrant docker image from the current working directory
  • Deploy Kuadrant control plane (including istio, authorino and limitador)

TODO: customize with custom authorino and limitador git refs. Make sure Makefile propagates variable to deploy target

Deploy kuadrant operator using OLM

You can deploy kuadrant using OLM just running few commands. No need to build any image. Kuadrant engineering team provides latest and release version tagged images. They are available in the Quay.io/Kuadrant image repository.

Create kind cluster

make kind-create-cluster

Deploy OLM system

make install-olm

Deploy kuadrant using OLM. The make deploy-catalog target accepts the following variables:

Makefile Variable Description Default value
CATALOG_IMG Kuadrant operator catalog image URL quay.io/kuadrant/kuadrant-operator-catalog:latest 
make deploy-catalog [CATALOG_IMG=quay.io/kuadrant/kuadrant-operator-catalog:latest]

Build custom OLM catalog

If you want to deploy (using OLM) a custom kuadrant operator, you need to build your own catalog. Furthermore, if you want to deploy a custom limitador or authorino operator, you also need to build your own catalog. The kuadrant operator bundle includes the authorino or limtador operator dependency version, hence using other than latest version requires a custom kuadrant operator bundle and a custom catalog including the custom bundle.

Build kuadrant operator bundle image

The make bundle target accepts the following variables:

Makefile Variable Description Default value Notes
IMG Kuadrant operator image URL quay.io/kuadrant/kuadrant-operator:latest TAG var could be use to build this URL, defaults to latest if not provided
VERSION Bundle version 0.0.0
LIMITADOR_OPERATOR_BUNDLE_IMG Limitador operator bundle URL quay.io/kuadrant/limitador-operator-bundle:latest LIMITADOR_OPERATOR_VERSION var could be used to build this, defaults to latest if not provided
AUTHORINO_OPERATOR_BUNDLE_IMG Authorino operator bundle URL quay.io/kuadrant/authorino-operator-bundle:latest AUTHORINO_OPERATOR_VERSION var could be used to build this, defaults to latest if not provided
DNS_OPERATOR_BUNDLE_IMG DNS operator bundle URL quay.io/kuadrant/dns-operator-bundle:latest DNS_OPERATOR_BUNDLE_IMG var could be used to build this, defaults to latest if not provided
RELATED_IMAGE_WASMSHIM WASM shim image URL oci://quay.io/kuadrant/wasm-shim:latest WASM_SHIM_VERSION var could be used to build this, defaults to latest if not provided
  • Build the bundle manifests
make bundle [IMG=quay.io/kuadrant/kuadrant-operator:latest] \
            [VERSION=0.0.0] \
            [LIMITADOR_OPERATOR_BUNDLE_IMG=quay.io/kuadrant/limitador-operator-bundle:latest] \
            [AUTHORINO_OPERATOR_BUNDLE_IMG=quay.io/kuadrant/authorino-operator-bundle:latest] \
            [DNS_OPERATOR_BUNDLE_IMG=quay.io/kuadrant/dns-operator-bundle:latest] \
            [RELATED_IMAGE_WASMSHIM=oci://quay.io/kuadrant/wasm-shim:latest]
  • Build the bundle image from the manifests
Makefile Variable Description Default value
BUNDLE_IMG Kuadrant operator bundle image URL quay.io/kuadrant/kuadrant-operator-bundle:latest 
make bundle-build [BUNDLE_IMG=quay.io/kuadrant/kuadrant-operator-bundle:latest]
  • Push the bundle image to a registry
Makefile Variable Description Default value
BUNDLE_IMG Kuadrant operator bundle image URL quay.io/kuadrant/kuadrant-operator-bundle:latest 
make bundle-push [BUNDLE_IMG=quay.io/kuadrant/kuadrant-operator-bundle:latest]

Frequently, you may need to build custom kuadrant bundle with the default (latest) Limitador and Authorino bundles. These are the example commands to build the manifests, build the bundle image and push to the registry.

In the example, a new kuadrant operator bundle version 0.8.0 will be created that references the kuadrant operator image quay.io/kuadrant/kuadrant-operator:v0.5.0 and latest Limitador and Authorino bundles.

# manifests
make bundle IMG=quay.io/kuadrant/kuadrant-operator:v0.5.0 VERSION=0.8.0

# bundle image
make bundle-build BUNDLE_IMG=quay.io/kuadrant/kuadrant-operator-bundle:my-bundle

# push bundle image
make bundle-push BUNDLE_IMG=quay.io/kuadrant/kuadrant-operator-bundle:my-bundle

Build custom catalog

The catalog's format will be File-based Catalog.

Make sure all the required bundles are pushed to the registry. It is required by the opm tool.

The make catalog target accepts the following variables:

Makefile Variable Description Default value
BUNDLE_IMG Kuadrant operator bundle image URL quay.io/kuadrant/kuadrant-operator-bundle:latest
LIMITADOR_OPERATOR_BUNDLE_IMG Limitador operator bundle URL quay.io/kuadrant/limitador-operator-bundle:latest
AUTHORINO_OPERATOR_BUNDLE_IMG Authorino operator bundle URL quay.io/kuadrant/authorino-operator-bundle:latest
DNS_OPERATOR_BUNDLE_IMG DNS operator bundle URL quay.io/kuadrant/dns-operator-bundle:latest 
make catalog [BUNDLE_IMG=quay.io/kuadrant/kuadrant-operator-bundle:latest] \
            [LIMITADOR_OPERATOR_BUNDLE_IMG=quay.io/kuadrant/limitador-operator-bundle:latest] \
            [AUTHORINO_OPERATOR_BUNDLE_IMG=quay.io/kuadrant/authorino-operator-bundle:latest] \
            [DNS_OPERATOR_BUNDLE_IMG=quay.io/kuadrant/dns-operator-bundle:latest]
  • Build the catalog image from the manifests
Makefile Variable Description Default value
CATALOG_IMG Kuadrant operator catalog image URL quay.io/kuadrant/kuadrant-operator-catalog:latest 
make catalog-build [CATALOG_IMG=quay.io/kuadrant/kuadrant-operator-catalog:latest]
  • Push the catalog image to a registry
make catalog-push [CATALOG_IMG=quay.io/kuadrant/kuadrant-operator-bundle:latest]

You can try out your custom catalog image following the steps of the Deploy kuadrant operator using OLM section.
