GHao

This is my personal project developed to learn GObject and Gtk libraries. It is a graphical interface to our internal Kubernetes management tools. Unfortunately, this application can not be used out-of-the-box without those tools.

Since it is quite difficult to find any resources regarding GObject and Gtk on the internet, I hope that this code might be useful for some of the learners. I think it should be relatively easy to fork this project and change it into any kind of fancy list-displaying utility. Help yourself!

Usage (with fake data)

Make sure that you have the dependencies installed by following instructions on PyGObject documentation and installing packages from requirements.txt:

pip3 install -r requirements.txt

Sorry, but PyGObject can not be installed the same way :(.

Then just invoke:

python3 -m ghao

An application window should show up with some fake records. The rest should be intuitive or at least such is my intent.

Real usage

By default the application uses fake Kubernetes object implemented in ghao/fakectl.py. This means that it does not require a working K8s cluster and you are safe to experiment with the GUI.

To use a real K8s instance make sure that kubectl utility is installed on your machine and switch the FAKE_KUBERNETES constant somewhere in the code. This should work if your system is set up accordingly to our internal guidelines :D.

Unfortunately, if it is not the case, you will need to reimplement the KubeCtl class yourself. The original version is based on our internal library which makes too many assumptions about our internal workflow. Most of the functions can be left unchanged (e.g. describe_cmd, kill_cmd) others should be relatively easy to implement (e.g. get_jobs - refer to the FakeKubeCtl class).
