Kubernetes is an open-source container-orchestration system for automating computer application deployment, scaling, and management. It was originally designed by Google and is now maintained by the Cloud Native Computing Foundation. It aims to provide a "platform for automating deployment, scaling, and operations of container workloads". It works with a variety of container runtimes such as Docker, Containerd, and CRI-O. Versio.io can import, historize and process monitoring data from Kubernetes.
You can find the configuration option in Versio.io at
Environment settings > OneImporter > Configurations > Kubernetes.
Basically, setting up a configuration is not necessary for this module. The activation on the side of the OneImporter is sufficient to already start importing the data. An additional configuration can be created to restrict the import or to overwrite defaults.
Here you can edit all existing configurations, create new configurations or delete existing configurations.
To add a new configuration enter a
Name for your importer.
Add to proceed to the configuration.
To edit an existing configurations click the arrow on the left of your importer name to expand the configuration options.
Following configuration options are available:
|Name||Meaningful name||Add the word "Kubernetes" to identify importer when viewing the logs|
|Active||Option to activate and deactivate the configuration. Data is only imported if the configuration is activated.|
|Filter namspaces||Blacklist for omitting specified namespaces|
|Executing OneImporter||Select a Versio.io OneImporter to import the data based on the importer configuration.||Requires installed OneImporter: Installation instruction|

The Versio.io OneImporter imports Kubernetes data based on a specific configuration into entities with a suffix (default:
kubernetes). To view the imported instances in Versio.io, select 'Asset & Configuration Repository → Instance Viewer'. There you can select your specific instance and click it for a detailed view in the instance history viewer.
