Clear Linux\* OS on Microsoft\* Azure\*
|
|
#######################################
|
|
|
|
Clear Linux OS is now an offering in the Azure Marketplace.
|
|
|
|
Clear Linux OS is designed with cloud and data center environments in mind
|
|
and is tuned to maximize the performance and value of Intel® architecture.
|
|
In Azure our boot times are lightning-quick, with all on-boot services
|
|
launched in less than a second on nodes with warm caches [1]_.
|
|
|
|
There are three offerings of Clear Linux OS within the Azure Marketplace.
|
|
They can be created through the `Azure Portal <https://portal.azure.com>`_ or
|
|
by using the `Azure Command Line tools <https://github.com/Azure/azure-cli>`_.
|
|
Each offering can be further customized by using the swupd command to
|
|
install additional bundles. Learn more about Clear Linux OS and bundles in
|
|
our :ref:`documentation<clear-linux>`.
|
|
|
|
For additional information visit the Clear Linux
|
|
`Azure Partner Mini Case Study`_ and the `Azure Partner Datasheet`_
|

|
Offerings
|
|
=========
|
|
|
|
The three offerings, and the commands to launch VM instances from the command line for each, are:
|
|
|
|
* **Basic** - This is a bare-bones generic offering, from which users may
|
|
extend functionality by adding bundles of their choosing:
|
|
|
|
* **Containers** - This offering comes with the containers-basic bundle already
|
|
installed.
|
|
|
|
* **Machine Learning** - This offering comes pre-loaded with popular open
|
|
source tools for developing machine learning applications.
|
|
|
|
Azure Command Line Interface
|
|
============================
|
|
|
|
The Azure Command Line Interface offers the ability to create and manage
|
|
resources in Azure from the command line. The examples here are based on
|
|
Version 1.0 of the Azure CLI, which is implemented in Javascript and
|
|
distributed through the Node Package Manager. Version 2.0 of the Azure CLI is
|
|
implemented in Python. This example will be updated when Azure CLI 2.0 is fully
|
|
released.
|
|
|
|
The following command shows the version number of the most recent images that
|
|
have been uploaded into the Azure Marketplace.
|
|
|
|
::
|
|
|
|
azure vm image list -p clear-linux-project -l westus -o clear-linux-os | grep -v "Getting" | cut -f5 -d: | sed -e 's/\s*//g'| sed -e 's/\..*//' | sort -u | tail -1
|
|
|
|
The following scriplet can be used to create and start a virtual machine
|
|
instance in Azure based on a marketplace offering. The resource group needs to
|
|
already exist. This script tries to use a resource group of the form
|
|
"<azure_username>-clr-vms". For example, for an Azure user named Rob trying to
|
|
create an instance of version ``12920`` of the ``basic`` offering for Clear
|
|
Linux OS, this script creates an instance with the public hostname of
|
|
``rob-12920-basic-1234``.
|
|
|
|
::
|
|
|
|
#!/bin/bash
|
|
clrversion=XXXXX
|
|
azuser='azure_username'
|
|
location="westus"
|
|
resourceGroup="${azuser}-clr-vms"
|
|
offering=basic
|
|
# offering=containers
|
|
# offering=machine-learning
|
|
uniquesuffix=$((1 + RANDOM % 1000)) # More like "probably unique suffix"...
|
|
|
|
azure vm create --vm-size Standard_D1_v2 \
|
|
--admin-username ${azuser} \
|
|
--ssh-publickey-file ~/.ssh/id_rsa.pub \
|

SSH Sessions
|
|
============
|
|
|
|
To keep SSH sessions to Clear Linux Guests in Azure from being dropped
|
|
after periods of inactivity, you can give the following option to SSH via
|
|
the command line::
|
|
|
|
-o ServerAliveInterval=180
|
|
|
|
Alternatively, you can add this setting to your SSH config file as shown
|
|
below::
|
|
|
|
Host *:
|
|
ServerAliveInterval 180
|
|
|
|
