+# Disclaimer
+
+This document collects information how to deal with debugging an openDesk deployment.
+
+It will be extended over time as we have to deal with debugging cases.
+
+We for sure do not want to reinvent the wheel, so we might link to external sources that contain helpful
+information where available.
+
+**Note:** You should never enable debug in production environments! By looking up `debug.enable` in the deployment you
+will find the various places changes are applied when enabling debugging. So outside of development and test
+environments you may want to make use of them in a very thoughtful and selective manner if needed.
+
+# Enable debugging
+
+Set `debug.enable` to `true` in [`debug.yaml`](../helmfile/environments/default/debug.yaml) to set the
+component's loglevel to debug and it get some features like:
+- The `/admin` console is routed for Keycloak.
+- An ingress for `http://minio-console.<your_domain>` is configured.
+and set the loglevel for components to "Debug".
+
+**Note:** All containers should write their log output to STDOUT, if you find (valuable) logs inside a container, please let us know!
+
+# Components
+
+## MariaDB
+
+When using the openDesk bundled MariaDB you can explore database(s) using the MariaDB interactive terminal from the pod's command line: `mariadb -u root -p`. As password provide the value for `MARIADB_ROOT_PASSWORD` set in the pod's environment.
+
+While you will find all details for the CLI tool in [the online documentation](https://mariadb.com/kb/en/mariadb-command-line-client/), some quick commands are:
+
+- `help`: Get help on the psql command set
+- `show databases`: Lists all databases
+- `use <databasename>`: Connect to `<databasename>`
+- `show tables`: Lists tables within the currently connected database
+- `quit`: Quit the client
+
+## Nextcloud
+
+`occ` is the CLI for Nextcloud, all the details can be found in the [upstream documentation](https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/occ_command.html).
+
+You can run occ commands in the `opendesk-nextcloud-php` pod like this: `php /var/www/html/occ config:list`
+
+## OpenProject
+
+OpenProject is a Ruby on Rails application. Therefore you can make use of the Rails console from the pod's command line `bundle exec rails console`
+
+and run debug code like this:
+
+```
+uri = URI('https://nextcloud.url/index.php/apps/integration_openproject/check-config')
+Net::HTTP.start(uri.host, uri.port,
+  :use_ssl => uri.scheme == 'https') do |http|
+  request = Net::HTTP::Get.new uri
+  response = http.request request # Net::HTTPResponse object
+end
+```
+
+## PostgreSQL
+
+When using the openDesk bundled PostgreSQL you can explore database(s) using the PostgreSQL interactive terminal from the pod's command line: `psql -U postgres`.
+
+While you will find all details in the [psql subsection](https://www.postgresql.org/docs/current/app-psql.html)) of the PostgreSQL documentation, some quick commands are:
+
+- `\?`: Get help on the psql command set
+- `\l`: Lists all databases
+- `\c <databasename>`: Connect to `<databasename>`
+- `\dt`: List (describe) tables within the currently connected database
+- `\q`: Quit the client
