PyPI Package CI status Coverage

What is this?

kubetop is a top(1)-like tool for Kubernetes.

NOTE kubetop does not work against recent versions of Kubernetes anymore due to Kubernetes API changes. This is not expected to change in the near future. Patches welcome.

Usage Sample

$ kubetop

Installing

Pip / Pipsi

Python 2.7 is required to run kubetop.

To install the latest version of kubetop using pip or pipsi:

$ pipsi install kubetop

Docker

A Docker image containing a kubetop installation is also available. You can run it like this:

$ docker run -it --rm --volume ~/.kube/:/root/.kube/:ro exarkun/kubetop

Testing

kubetop uses pyunit-style tests. After installing the development dependencies, you can run the test suite with trial:

$ pip install kubetop[dev]
$ trial kubetop

Version

kubetop uses the CalVer versioning convention. The first three segments of a kubetop version tell you the year (two digit), month, and day that version was released. The fourth segment of a kubetop version is a bugfix release counter. It is present if a new release is made that diffs from a previous release only by including one or more bug fixes. For each bug fix release, the fourth segment is incremented.
