Services

In this context a (Stackable) service is a running instance of a data product. This is different from the meaning of a Kubernetes service which is an abstract way to expose an application running on a set of pods as a network service.

List running services

The stackablectl services command allows to inspect the running services of the Stackable data platform. Currently you can only get a read-only view of the running services, future versions may allow to e.g. uninstall running services.

An example invocation looks as follows:

$ stackablectl services list --all-namespaces
 PRODUCT   NAME         NAMESPACE  ENDPOINTS                                     EXTRA INFOS

 hive      hive         default    hive                172.18.0.4:32658
                                   metrics             172.18.0.4:30745

 opa       opa          default    http                http://172.18.0.2:31324

 superset  superset     default    external-superset   http://172.18.0.2:32716   Admin user: admin, password: admin

 trino     trino        default    coordinator-http    http://172.18.0.5:32128
                                   coordinator-metrics 172.18.0.5:31199
                                   coordinator-https   https://172.18.0.5:32721

 minio     minio-trino  default    http                http://172.18.0.4:31026   Third party service
                                   console-http        http://172.18.0.4:30354   Admin user: root, password: rootroot

When a product instance has not finished starting yet, the service will have no endpoint. Starting all of the product instances might take an considerable amount of time depending on your internet connectivity. In case the product is not ready yet a warning might be shown.

You can also

  • Show services in all namespaces

  • Redact the passwords from the output in case you want to share the list of services without giving out the admin credentials

  • Print the installed product versions

To achieve this you can use the following command:

$ stackablectl services list --all-namespaces --redact-credentials --show-versions
