Azure VM Utilities!

NOTE:

• Entering your "subscription_id" in azure_utils/data/config/host_config.json is NOT optional.
• Everything else IS optional.

WARNING: IT IS NOT SAFE TO PERMANENTLY STORE YOUR AZURE SERVICE-PRINCIPAL CREDENTIALS IN A PLAINTEXT JSON DOC. DO NOT SKIP THE README SECTION ON STORING CREDENTIALS.

Usage:

The -j flag indicates you're using the default json-file to store your AAD service-principal credentials.

~$ azureutils -j turnon remotehost-A
remotehost-A has been turned on.

Note that the statusof keyword retrieves the actual hostname.

~$ azureutils -j statusof remotehost-A
Webserver-A-WestUS2 is currently running. It's been on since: 2016-09-30 22:04:22.355673+00:00

Note also that we can get long-form stats by using the -l flag.

~$ azureutils -jl statusof remotehost-A
REMOTEHOST-A:
resource_id: ==> 8ee39295-312a-4df0-a928-80a23028fc87
hostname: ==> Webserver-A-WestUS2
last_up: ==> 2016-09-30 22:04:22.355673+00:00
prov_state: ==> Updating
power_state: ==> VM running
location: ==> westus2

Turning off a vm is not the same as deallocating it! Good for rebooting without changing your dynamic-ip.

~$ azureutils -j turnoff remotehost-A
remotehost-A has been shut down.

~$ azureutils -j statusof remotehost-A
Webserver-A-WestUS2 is currently stopped (vm is still allocated).

Let's deallocate & get the long-form status to be sure:

~$ azureutils -j deallocate remotehost-A
remotehost-A has been deallocated.

~$ azureutils -jl statusof remotehost-A
REMOTEHOST-A:
resource_id: ==> 8ee39295-312a-4df0-a928-80a23028fc87
hostname: ==> Webserver-A-WestUS2
last_up: ==> 2017-09-30 22:04:22.355673+00:00
prov_state: ==> Provisioning succeeded
power_state: ==> VM deallocated
location: ==> westus2

aaaand that's all for now.

Pre-Install:

This package has dependencies on: msrest, msrestazure, azure, & azure-common.

To get them all, run the following command from the shell:

~$ pip install msrest==0.4.0 msrestazure==0.4.0 azure=="2.0.0rc5" azure-common==1.1.4

After that,

~$ git clone https://github.com/rtruxal/azure_utils.git && cd ./azure_utils

Now, you're going to need to populate your host-list & determine if you wanna use the credential-file. Either way, you're gonna need to:

GO TO THE azure_utils/config/ DIRECTORY.

Then you're prly gonna wanna...

EDIT azure_utils/config/data/host_config.json

&

azure_utils/config/data/credentials_config.json

K now when you're done, proceed.

Installation:

~$ pwd
/path/to/azure_utils
~$ pip install .

& bam you're done.

Storing or Passing-in Credentials:

you need to explicitly pass in your service principals via 1 of 3 mechanisms.

# Here are your 3 options:


# 1.
#-----by using the internal JSON file (AND READING THE DAMN WARNING.txt)
~$ azureutils [-j|--json-credentials] turnon myVM1
myVM1 has been turned on.


# 2.
#----arg placement dont matta. .ini or xml-style plz.
~$ azureutils deallocate myVM2 [-i|--infile-credentials] /path/to/service/principal/credentials.txt
host2 successfully deallocated.

# 3.
#----prompt! (this'n is the default!...for safety!)
~$ azureutils restart myVM1
enter the exact tenant ID including dashes:
enter the exact Application/Client ID including dashes:
enter your secret service-principal code:

myVM1 restarted.
