Creating CR objects

[TheCodeAddiction]

Hey! I am trying to create an operator that is quite simple, but I am have some questions.

What I am trying to do is quite simple:

• I have created a operator for my CR called foo
• I now want my operator, to create a CR bar. Bar has its own stand alone operator currently deployed in our cluster.
• Currently, I don't need to implement ownership between foo and bar, however in the future, that is something I am gonna do.

Insides foo's reconcile method, how do I apply a bar CR to my cluster? Could someone give me a quick demo on how to deploy a CR with the operator_sdk framework?

Take a look at: https://github.com/quarkiverse/quarkus-operator-sdk/tree/main/samples/joke. This sample operator does the same kind of thing you're trying to do: when a JokeRequest CR is applied to the cluster, it queries an external joke API and uses the retrieved information to create a Joke CR on the cluster. If you have a CRD for your bar CR, you could generate the Java code for it using Fabric8's client java code generator as well. Take a look at https://github.com/java-operator-sdk/java-operator-sdk/tree/main/sample-operators/leader-election which demonstrates this contract-first approach.
