The #jsonnet channel on Kubernetes Slack is for discussion around the use of Jsonnet with Kubernetes.
There is also an IRC channel: #jsonnet on the freenode network (chat.freenode.net).

You're welcome to contribute to Jsonnet via Github and do share your plans with us even if you're at an early stage. If it's your first time submitting a pull request, a bot will ask you to sign either the Google individual or corporate contributor license agreement (CLA). CLAs are a common requirement when patching open source software projects owned by large companies.
