@pires , @wallyqs - Although not explicitly tested, this issue is resolved by #26, right?

[wallyqs]

@ColinSullivan1 that is one part needed but also a few more parts pending:

• Make it possible to parameterize the auth via the ClusterSpec here

  nats-operator/pkg/spec/cluster.go

  Line 60 in 1478d4a

  type ClusterSpec struct {

• Codegen updates for the new field for Auth support
• Include the Authorization field when present to the generated config
  

  nats-operator/pkg/util/kubernetes/kubernetes.go

  Lines 238 to 245 in 1478d4a

  	sconfig := &natsconf.ServerConfig{
  	Port: int(constants.ClientPort),
  	HTTPPort: int(constants.MonitoringPort),
  	Cluster: &natsconf.ClusterConfig{
  	Port: int(constants.ClusterPort),
  	Routes: routes,
  	},
  	}

• Do the same for cluster config (for this we could generate password on the fly I think but for client auth it needs to be customizable somehow)

  Authorization *AuthorizationConfig `json:"authorization,omitempty"`
