They watch on your Kubernetes cluster…

Kubemen is a Kubernetes validating admission webhook_ that sends notifications when a resource changes on your cluster, heavily influenced by the Watchmen (2009) movie.

Currently supported channels:

• Mattermost_
• emails

Documentation: https://kubemen.readthedocs.io

Installation

Kubernetes

Requirements:

• ValidatingAdmissionWebhooks being enabled on your cluster
• you being an administrator of the cluster

If these requirements are fulfilled, installing Kubemen on your cluster is pretty straightforward:

• create TLS certificates for the service and sign them through the CSR API:

.. code-block:: bash

$ sh deploy/create-cert.sh

• deploy Kubemen:

.. code-block:: bash

$ cat deploy/kubemen.yaml | sh deploy/patch-ca-bundle.sh | kubectl apply -f -

Locally

If you want to hack on Kubemen:

• create and activate a virtualenv_:

.. code-block:: bash

$ virtualenv -ppython3 .venv
$ .venv/bin/activate

• install the application requirements with pip_:

.. code-block:: bash

(.venv) $ pip install -r requirements.txt

• run it with:

.. code-block:: bash

(.venv) $ python run.py

Tests

To run Kubemen tests:

• install Kubemen locally (see above);
• install developers requirements with pip install -r dev-requirements.txt;
• run pytest.
