1) Install operator-sdk on your computer https://github.com/operator-framework/operator-sdk/blob/master/doc/user/install-operator-sdk.md. I prefer to install into $GOPATH/bin.
2) create script somewhere like /opt/bootstrap_operator.sh
#!/bin/bash
set -e
REPO="git.blindage.org/21h/redis-operator"
API_VERSION="blindage.org/v1alpha1"
KIND="Redis"
NAME="redis-operator"
# operator sdk
export GO111MODULE=on
echo "Bootstraping ${NAME}"
operator-sdk new ${NAME} --git-init --repo ${REPO} --verbose
cd ${NAME}
echo "Adding API ${API_VERSION}"
operator-sdk add api --api-version=${API_VERSION} --kind=${KIND} --verbose
echo "Creating controller"
operator-sdk add controller --api-version=${API_VERSION} --kind=${KIND} --verbose
3) change directory to your “~/dev” and run script bash /opt/bootstrap_operator.sh, it will create new directory “~/dev/redis-operator”
4) build your new operator, pack to image operator-sdk build redis-operator
5) push new image to registry with docker push myregistry.ru/redis-operator
