Development Guide

Technology stack required for development

Build

make build

Deploy on local kubernetes cluster

Run local Kubernetes cluster using Docker container using Kind and deploy kuadrant operator (and all dependencies) in a single command.

make local-setup

The make local-setup target accepts the following variables:

Makefile Variable Description Default value
GATEWAYAPI_PROVIDER GatewayAPI provider name. Accepted values: [istio | envoygateway] istio

Run as a local process

Run local Kubernetes cluster using Docker container using Kind and deploy all dependencies in a single command.

make local-env-setup

The make local-env-setup target accepts the following variables:

Makefile Variable Description Default value
GATEWAYAPI_PROVIDER GatewayAPI provider name. Accepted values: [istio | envoygateway] istio

Then, run the operator locally

make run

Deploy on existing kubernetes cluster

Requirements:

  • Active session open to the kubernetes cluster.
  • GatewayAPI installed
  • GatewayAPI provider installed. Currently only Istio and EnvoyGateway supported.
  • Cert Manager installed

Before running the kuadrant operator, some dependencies needs to be deployed.

make install
make deploy-dependencies

Then, deploy the operator

make deploy

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
CHANNELS Bundle channels used in the bundle, comma separated alpha
DEFAULT_CHANNEL The default channel used in the bundle alpha
  • 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] \
            [CHANNELS=alpha] \
            [DEFAULT_CHANNEL=alpha]
  • 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
DEFAULT_CHANNEL Catalog default channel alpha
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] \
            [DEFAULT_CHANNEL=alpha]
  • 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.
