In this article I will show you how to see, in real-time, a command output from a Chef recipe.
Executing a command, the chef way
As a command example, as I'm working with it right now, let's take the Kubernetes installation tool: kubeadm.
This app tells you what he is doing in its output.
I first did this:
While this runs the command successfully, all the command's output is invisible:
* execute[kubeadm init] action run - execute kubeadm init --token=vfopfv.fgum14jkv3ldssu8 --pod-network-cidr=10.244.0.0/16 --service-cidr=10.96.0.0/12 --service-dns-domain=cluster.local --apiserver-advertise-address=172.28.128.200 Executing a command, the Ruby way
Let's now make this real-time :
Now you get the command output in real time:
* ruby_block[kubeadm init] action run[init] Using Kubernetes version: v1.15.1 [preflight] Running pre-flight checks [preflight] Pulling images required for setting up a Kubernetes cluster [preflight] This might take a minute or two, depending on the speed of your internet connection ... 🎉
