Now that we have created controller.json, resource.json and the DockerFile, let's create the Operator using CRAFT.
First, let us check whether CRAFT is working in our machine.
$ craft version
This should display the version and other info regarding CRAFT.
If this gives an error saying "$GOPATH is not set", then set GOPATH to the location where you've installed Go.
Now that we have verified that CRAFT is working properly, creating the Operator with CRAFT is a fairly straight forward process:
craft create -c config/controller.json -r config/resource.json \ --podDockerFile resource/DockerFile -p
If the execution in the terminal stops at a certain point, do not assume that it has hanged. The command takes a little while to execute, so give it some time.
This will create the Operator template in $GOPATH/src, build operator.yaml for deployment, build and push Docker images for operator and resource. We shall see what these are individually in the next section.
