  }),
];

Then run:

jskube apply -f config.ts

Commands:

• jskube print -f foo.ts - print the yaml for foo.ts
• jskube get-env-vars --user service_user_name --namespace service_user_namespace - get the environment variables needed to connect to kubernetes as a given service user from CI
• jskube apply -f foo.ts - update the infrastructure to match foo.ts
• jskube diff -f foo.ts - show the changes if foo.ts is applied
• jskube delete -f foo.ts - delete all the resources in foo.ts (also aliased as jskube destroy -f foo.ts)
• all other commands passed through, but with the -f parameter handled by jskube
