Description

// TODO(user): An in-depth paragraph about your project and overview of use

Getting Started

Prerequisites

• go version v1.24.6+
• docker version 17.03+.
• kubectl version v1.11.3+.
• Access to a Kubernetes v1.11.3+ cluster.

To Deploy on the cluster

Build and push your image to the location specified by IMG:

make docker-build docker-push IMG=<some-registry>/search-operator:tag

NOTE: This image ought to be published in the personal registry you specified. And it is required to have access to pull the image from the working environment. Make sure you have the proper permission to the registry if the above commands don’t work.

Install the CRDs into the cluster:

make install

Deploy the Manager to the cluster with the image specified by IMG:

make deploy IMG=<some-registry>/search-operator:tag

NOTE: If you encounter RBAC errors, you may need to grant yourself cluster-admin privileges or be logged in as admin.

Create instances of your solution You can apply the samples (examples) from the config/sample:

kubectl apply -k config/samples/

NOTE: Ensure that the samples has default values to test it out.

To Uninstall

Delete the instances (CRs) from the cluster:

kubectl delete -k config/samples/

Delete the APIs(CRDs) from the cluster:

make uninstall

UnDeploy the controller from the cluster:

make undeploy

Project Distribution

Following the options to release and provide this solution to the users.

By providing a bundle with all YAML files

1. Build the installer for the image built and published in the registry:

make build-installer IMG=<some-registry>/search-operator:tag

NOTE: The makefile target mentioned above generates an 'install.yaml' file in the dist directory. This file contains all the resources built with Kustomize, which are necessary to install this project without its dependencies.

1. Using the installer

Users can just run 'kubectl apply -f ' to install the project, i.e.:

kubectl apply -f https://raw.githubusercontent.com/<org>/search-operator/<tag or branch>/dist/install.yaml

By providing a Helm Chart

1. Build the chart using the optional helm plugin

kubebuilder edit --plugins=helm/v2-alpha

1. See that a chart was generated under 'dist/chart', and users can obtain this solution from there.

NOTE: If you change the project, you need to update the Helm Chart using the same command above to sync the latest changes. Furthermore, if you create webhooks, you need to use the above command with the '--force' flag and manually ensure that any custom configuration previously added to 'dist/chart/values.yaml' or 'dist/chart/manager/manager.yaml' is manually re-applied afterwards.

Contributing

// TODO(user): Add detailed information on how you would like others to contribute to this project

NOTE: Run make help for more information on all potential make targets

More information can be found via the Kubebuilder Documentation

Test Locally

Copy the .env.example to .env and replace urls:

cp .env.example .env

run the operator to reconcile the searchindex APIResource:

go run cmd/main.go

test by manually adding a searchindex resource:

export KUBCONFIG=<path to an KCP admin kubeconfig>
kubectl apply -f ./scripts/searchindex-test-resource.yaml --server="https://localhost:8443/clusters/root:orgs"

observe logs of successful reconciliation (start with KCP kubeconfig configured with path :root:platform-mesh-system):

# In shell:
searchindex.core.platform-mesh.io/testindex5 created
# In Operator
{"level":"info","service":"...","operator":"searchindex","controller":"SearchIndexReconciler","name":"<index name>","namespace":"","reconcile_id":"...","time":"...","caller":"...","message":"start reconcile"}

check if the url with your new index name in the path returns the desired values:

https://opensearch.portal.localhost:8443/<index name>
