Quickstart for Go-based Operators

This guide walks through an example of building a simple memcached-operator using tools and libraries provided by the Operator SDK.

• Go through the installation guide.
• User authorized with permissions.

1. Create a project directory for your project and initialize the project:

1. Create a simple Memcached API:

1. Use the built-in Makefile targets to build and push your operator. Make sure to define IMG when you call make:

export USERNAME=<quay-namespace>
export OPERATOR_IMG="quay.io/$USERNAME/memcached-operator:v0.0.1"
make docker-build docker-push IMG=$OPERATOR_IMG

SHELL := /bin/bash

1. Install :

1. Bundle your operator and push the bundle image:

make bundle IMG=$OPERATOR_IMG
export BUNDLE_IMG="quay.io/$USERNAME/memcached-operator-bundle:v0.0.1"
make docker-push IMG=$BUNDLE_IMG

1. Run your bundle:

operator-sdk run bundle $BUNDLE_IMG

1. Create a sample Memcached custom resource:

1. Uninstall the operator:

operator-sdk cleanup memcached-operator

Direct deployment

1. Deploy your operator:

make deploy IMG=$OPERATOR_IMG

1. Create a sample Memcached custom resource:
