Tired of having to wait for Cloudshare's progress bar to fill up? Here is a script that does it for you.

Visualize the interaction between the Kubernetes apiserver and the cert-manager webhook using mimtproxy

This mitmproxy file was created using Kubernetes 1.21 and cert-manager 1.7.

To visualize this HTTP interaction, install mitmproxy and run:

The slight differences between Unix tools across BSD (incl. macOS), GNU/Linux, and Busybox

Deploy a dev version of cert-manager to your GKE or OpenShift cluster

If you would like to use the new Make flow (we dropped Bazel!), here is a tutorial on how test cert-manager on a non-kind cluster such as GKE or OpenShift. In this tutorial, I assume that you have cloned cert-manager/cert-manager and that you have a shell session open in that folder. I also assume that your GKE or OpenShift cluster has access to the Docker Hub registry (i.e., you cluster has access to the internet).

You will need docker, helm, and crane installed. If you are on macOS or on Linux, you can install helm and crane using Homebrew:

Dev Assistant (chrome extension) settings

This gist can be shared, no problem.

Update 6 June 2022: it seems like dev assistant, which was published as a Chrome extension, has been withdrawn (probably by their authors). The source code for the extension is on GitHub: https://github.com/shridhar-tl/dev-assist. I don't know how to add the extension "manually" using the source code.
