FENCE_AGENT(8) System Manager's Manual FENCE_AGENT(8)

fence_azure_arm - Fence agent for Azure Resource Manager

Used to deallocate virtual machines and to report power state of virtual machines running in Azure. It uses Azure SDK for Python to connect to Azure.

For instructions to setup credentials see: https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-create-service-principal-portal

Username and password are application ID and authentication key from "App registrations".

NOTE: NETWORK FENCING
Network fencing requires an additional Subnet named "fence-subnet" for the Virtual Network using a Network Security Group with the following rules:
+-----------+-----+-------------------------+------+------+-----+-----+--------+
| DIRECTION | PRI | NAME | PORT | PROT | SRC | DST | ACTION |
+-----------+-----+-------------------------+------+------+-----+-----+--------+
| Inbound | 100 | FENCE_DENY_ALL_INBOUND | Any | Any | Any | Any | Deny |
| Outbound | 100 | FENCE_DENY_ALL_OUTBOUND | Any | Any | Any | Any | Deny |
+-----------+-----+-------------------------+------+------+-----+-----+--------+

When using network fencing the reboot-action will cause a quick-return once the network has been fenced (instead of waiting for the off-action to succeed). It will check the status during the monitor-action, and request power-on when the shutdown operation is complete.

fence_azure_arm accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_azure_arm can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.
