Command-line options

The following command-line options are supported for the operator:

  • -kubeconfig the path to the kubeconfig file. Usually named config, it contains authorization information as well as the URL of the Kubernetes master.

  • -outofcluster run the operator on a client machine, as opposed to a within the cluster. When running in this mode, the operator cannot connect to databases inside the cluster, as well as call URLs of in-cluster objects (i.e. teams api server). Mostly useful for debugging, it also requires setting the OPERATOR_NAMESPACE environment variable for the operator own namespace.

  • -nodatabaseaccess disable database access from the operator. Equivalent to the enable_database_access set to off and can be overridden by the aforementioned operator configuration option.

  • -noteamsapi disable access to the teams API. Equivalent to the enable_teams_api set to off can can be overridden by the aforementioned operator configuration option.

In addition to that, standard glog flags are also supported. For instance, one may want to add -alsologtostderr and -v=8 to debug the operator REST calls.
