Atomic Host demo on Google Compute Engine (GCE)

gistfile1.md

Overview

Basically four steps:

1. install SDK and initialize a new project via console
2. upload and generate a new GCE image for your project
3. instantiate a new instance on GCE using the image
4. follow a known path

install SDK and initialize a new project via console

• Sign up for Google Compute Engine
• Download and install the Cloud SDK
• Authenticate your client
• Set your project ID - "A project ID is the customized name you chose when you created the project, or when you activated an API that required you to create a project ID. It can be found in the Dashboard of the project ... ", see GCE doc

That's it for the first step...

upload and generate a new GCE image for your project

download and prepare Atomic Host image

download the current cloud image of Atomic Host and store it in your project directory.

cd <project-dir>
curl <URL of Atomic Host> -o rhel-atomic-host-cloud.qcow2.xz

convert

Convert the Atomic Host qcow2 to a raw file and package it with tar

xz --decompress rhel-atomic-host-cloud.qcow2.xz
qemu-img convert -S 4096 -f qcow2 -O raw rhel-atomic-host-cloud.qcow2 disk.raw
tar -Szcf rhel-atomic-host-image.tar.gz disk.raw

publish (upload) the tar

Upload the tar file into a Google Storage bucket.

gsutil mb gs://dingsbums
gsutil cp rhel-atomic-host-image.tar.gz gs://dingsbums

convert

After upload, the tar file is converted to a GCE image.

gcloud compute images create rhel-7-atomic-host --source-uri gs://dingsbums/rhel-atomic-host-image.tar.gz

instantiate a new instance on GCE using the image

gcloud compute images list

follow a known path

May I suggest a helpful comment saying that the raw image is required to be named disk.raw in the tarball.

Can you provide an example using kubectl instead of kubecfg?
