The Admin Dogu is a tool in the Cloudogu EcoSystem for administration and maintenance of Dogus. By offering functionality through a user interface which in other systems is often only accessible through the console, the Admin Dogu allows you as an administrator to manage your Cloudogu EcoSystem with very little effort.

You can reach the Admin Dogu in the Warp menu via the "Administration" entry in the section with the same name. Please note that the Admin Dogu is currently only available with a german interface.

Position in the warp menu

The Admin-Dogu currently offers the following functions:

  • Dogu Management
  • Maintenance.

Navigation bar of the Admin-Dogu

Dogu Management

With the Dogu Management you can start, stop and restart Dogus and download the Logs of individual Dogus.

A role with at least read access is required to use the Dogu Management area.

To use the start/stop/restart actions of the Dogu Management area, a role with at least at least write access is required.

In the default view you can see the Dogus that are accessible via the Warp menu. You can also manage the system components used in the EcoSystem via the Dogu Management. To do this, activate the checkbox System-Dogus einblenden, which will show another table with system components.

Download logs

With the help of the logs, it is possible to trace internal processes or investigate possible errors.

The Dogu Managements area lists all installed Dogus. You have the option of downloading a log file for each Dogu via the Logs herunterladen action. You can access the action by clicking on the three-dot menu in the Aktionen column.

Logging Bereich

Clicking on Logs herunterladen opens a dialog where you can specify how many lines of the log you want to download.

If the Komplett checkbox is activated, the entire log file is downloaded after confirmation by clicking the Herunterladen button.

Select the number of rows in the log file

If you deactivate the Komplett checkbox, you can specify the number of the last log lines to be downloaded in the Zeilen field.

If 0 lines are specified, the entire log file is downloaded.

Manually select the number of rows in the log file

The log file is downloaded as an archive (.zip).

Start, stop and restart

All available Dogus are displayed in Dogu Management.

Under Aktionen you can start, stop or restart each displayed d´Dogu. Only those actions are available that you can currently execute*. For example, you cannot select the *Start action for a currently running Dogu.

If a Dogu or a system component is relevant for the accessibility of the environment, the Stop action is actively prevented. Otherwise, the Dogu would not be able to be restarted via the user interface.

Dogu Management: View of components

The current status of the Dogu is displayed for each Dogu. The following states are possible for a Dogu:

  • gestartet: The Dogu is running and can be reached.
  • gestoppt: The Dogu has been stopped and cannot be reached.
  • startet neu: The Dogu has recently been restarted and is in the process of starting.
  • startet: The Dogu was stopped, was recently started and is in the process of starting.
  • stoppt: The Dogu was started, was recently stopped and is in the stopping process.
  • unbekannt: There was an error querying the Dogu state.

If you choose to stop or restart a Dogu, you have to confirm the respective action in a dialog box that opens.

Dogu Management: Dialog after clicking on "restart"

Dogu Management: Dialog after clicking on "stop"

Starting a Dogu does not have to be confirmed again. A successful start, stop or restart of a Dogu is indicated by a success message in the lower part of the screen.

Dogu Management: Successful start of a Dogu

If an error occurs while starting, stopping or restarting a Dogu, this will be indicated with an error message in the lower area.

Dogu Management: Failed to start a Dogu


Using Maintenance, you can enable or disable the debug mode. Additionally, you can create and download a Support Package that contains log files and other relevant information about the system. The Support Package can assist the Cloudogu GmbH support in analyzing problems in the Cloudogu EcoSystem.

A role with write access is required to use the Maintenance section.

For both the debug-mode and the support-package you can find further helpful hints directly next to the functions.

Maintenance: Maintenance section

Support package function

With a click on the button Neues Support-Paket erzeugen you can create a new current Support Package. Already created Support Packages can be downloaded directly as an archive (.zip) or deleted here.

Maintenance: Support package section

The generated Support Packages are stored in a directory on the host system and can be downloaded again at any time without having to reassemble them.

The support package contains the following information:

  • Configuration

    • etcd/etcd.tree - All in etcd stored keys as a tree structure (only the keys, no values)
    • etcd/etcd.json - All keys1 and their values in a json file (sensitive keys are excluded).
  • Logs

    • logs/[servicename].log - The log files of all installed Dogus as well as the services 'syslog', 'cesappd', 'cesapp', 'ces-setup' and 'backup-watcher'.
  • Dogu information

    • Dogu-information - Information about all installed Dogus, their status (started, stopped, etc.) and the size of their volumes
  • Environmental variables

    • env - All environmental variables set in the system
  • Process information

    • process-information - Information about all running processes and services, such as 'cesappd' and the 'backup-watcher'.
  • System information

    • system-information - Information about the system (installed hardware, operating system, partitions, utilization, memory consumption, installed packages)
  • Volume-information

    • volume-information - List of the file names of all volumes of the existing Dogus

1 You can exclude values of directories or keys from the etcd/etcd.json file. To do this, you must store the keys in etcd under config/_global/debug/excluded_etcd_keys. In the following example, the config and Dogu_v2 keys are excluded from the etcd/etcd.json file:

config/_global/debug/excluded_etcd_keys/<free-chosen-name-1> => config config/_global/debug/excluded_etcd_keys/<free-chosen-name-2> => Dogu_v2

In the file etcd/etcd.json the values of both keys are then censored:

   "config" : "***",
   "Dogu_v2" : "***"

Debug mode function

The Debug mode sets all Dogus to the highest log level (log level = DEBUG), which causes them to output the maximum amount of logs. Therefore, you can use the debug mode for reproducing bugs. Afterwards you can generate the support package with the extended log information.

Note that activating or deactivating the debug mode empties the log files (the old logs are archived in the process). Therefore, you should create a desired support package before deactivating the debug mode. It may also be useful to generate a support package before activating the debug mode as well.

Activating the debug mode is only possible for maximum 60 minutes to avoid problems due to the increased log level; the log level set in debug mode can generate a lot of output, which could cause log files to be several 100 Mb in size.

Maintenance: View of debug mode

Clicking the Debug-Modus aktivieren button opens a dialog to confirm the operation. Via button Abbrechen you can close the dialog without starting the debug mode.

Maintenance: Activating debug mode

When activating debug mode, please note that the entire system including the Admin Dogus will no longer be accessible via the user interface for several minutes. When activating the debug mode you will also be shown this information.

Maintenance: Warning when activating debug mode

While the debug mode is activated, the system is put into maintenance mode for a few minutes and the log levels are configured. Maintenance mode is shown to you via a maintenance page when you try to access the environment via the user interface.

Maintenance: View of general maintenance page of Cloudogu EcoSystem

When the maintenance mode is stopped, you need to reload the browser page. The page will not be refreshed automatically.

If the Debug mode is active, you have the option to end the Debug mode with the button Debug-Modus deaktivieren before the set time has elapsed.

Maintenance: View with activated debug mode

You can see how long the debug mode is still active by a hint below the navigation bar. This is displayed in all areas of the Admin Dogus.

Maintenance: View of time span of debug mode

If the deactivation of the debug mode is done in less than five minutes, the label will be highlighted.

Maintenance: View of time span of debug mode when debug mode is going to end in less than five minutes

You should deactivate the debug mode as soon as you don't need it anymore, for example after you have reproduced the bug and created the support package.

By clicking on Debug-Modus deaktivieren you will again get a dialog confirming that the environment will be unusable for a few minutes. Even when deactivating debug mode, the system will be unavailable for several minutes and will be in maintenance mode.

Maintenance: Deactivate debug mode

After the confirmation you will be shown this hint as well.

Maintenance: Warning when deactivating debug mode

After a successful deactivation of the debug mode you can use the system again as usual.

Roles and permissions

Currently there are roles in the Admin Dogu for reading, writing and administrative access to the application functionalities. You can see your assigned role in the navigation bar of the Admin Dogu at the user image left of your own user name.

The roles are predefined by default. However, via the configuration of the Admin Dogu in etcd you can rename them according to your wishes.

bash cesapp edit-config admin

To assign the required roles to users, manually create the required groups in User Management and assign the users as desired. Note that the groups should have the same name as defined in the Admin Dogus configuration in etcd.

Users without at least one of these roles have no access to the Admin Dogu.

Reading access

Users with this role have access to the Admin Dogu and can mainly view information, but cannot make any settings on the system.

You can configure the role as follows:

bash config/admin/groups/reader

By default this role is defined as adminReaders.

Write access

Users with this role have access to the Admin Dogu and can additionally modify data via the interface.

You can configure the role as follows:

bash config/admin/groups/writer

By default this role is defined as adminWriters.

Admin access

Users with this role have access to the Admin Dogu and can use all available functions via the user interface. In addition to the group configured via config/admin/groups/admin, all users are also granted administrative permissions, if they have been assigned the general admin group of the Cloudogu EcoSystem via the User Management.

You can configure the role as follows:

bash config/admin/groups/admin

By default this role is defined as adminAdmins.


If the Admin Dogu shows error messages in the tables instead of the installed Dogus, it may be due to an outdated version of the cesappd service. The Admin Dogu needs a cesappd service at least in version 3.0.2 to work correctly.

Admin Dogu in error state

You can install a current version of the cesappd service via apt: shell apt update && apt install cesappd

If this does not fix the error, you can reinstall the Admin Dogu:

# remove currently installed Dogu
cesapp purge admin && \
# reinstall Dogu from the premium namespace
cesapp install premium/admin && \
# start Dogu
cesapp start admin

The Admin Dogu does not hold any data in a database that could be lost.
