coreos-cloudinit not found. Could not validate config.

02 Jul

When Installing coreos, this is a common problem depending on the ‘live CD’ used:

./ -d /dev/sdb -C stable -c ~/cloud-config.yaml
./ coreos-cloudinit not found. Could not validate config. Continuing...\

All manner of ‘solutions’ appear on the internet, actually it is simply stating that ‘coreos-cloudinit’
is missing.

The reason being that the so called install scripts are actually not fully integrated.

Simply following the instructions at :

will ONLY work IF you use a liveCD that contains ‘coreos-cloudinit’

Get in the prerequisites first:

1. Build your cloud-config.yaml BUT validate it first at:

Then ensure that you perform the following BEFORE attempting the installation

your working directory:
cd coreos-cloudinit-master/
cd bin
#ensure you put the binary on a path where it can be found
cp coreos-cloudinit /usr/bin/coreos-cloudinit

Then cd back to your original working directory where you have: (or whatever you called it)

./ -d /dev/sdb -C stable -c ~/cloud-config.yaml

CentOS 6 installing the Graphical interface (GUI)

06 Aug

When doing work for customers I work mainly on VM installations. This allows me to try things out and then rollback the OS should anything not work out.(Just HOW cool is it to be able to take snapshots & rollbacks of a complete os!!)
