register

Creates and/or updates a ~/.chaos-extensions.json file. This file represents all the extensions the tool is aware of and able to run. Use register to add new extensions:

azchaos register myextension https://myextension.com "a description of my extension"

list

Lists all the registered extensions by printing them to stdout. Optionally filters by search term.

azchaos list [search]

unregister

Updates a ~/.chaos-extensions.json file. This file represents all the extensions the tool is aware of and able to run. Use unregister to remove extensions:

azchaos unregister myextension

start

Start is a registered chaos extension, effectively enabling a chaotic event. This command requires that a --resources argument is given, accepting an array of comma-separated resource identifier strings. Optionally, the --accessToken argument may be provided, accepting an Azure access token in the form of Bearer <token>. If --accessToken is not provided, the caller will be prompted to login interactively.

azchaos start myextension --resources "subId/resGroupName/resName","subId/resGroupName/resName2"

stop

Stop is a registered chaos extension, effectively disabling a chaotic event. This command requires that a --resources argument is given, accepting an array of comma-separated resource identifier strings. Optionally, the --accessToken argument may be provided, accepting an Azure access token in the form of Bearer <token>. If --accessToken is not provided, the caller will be prompted to login interactively.

azchaos stop myextension --resources "subId/resGroupName/resName","subId/resGroupName/resName2"

resgen

Generates a resource identifier string given an Azure subscription id, optionally an Azure resource group name, and (still optionally) an Azure resource name. The resulting tri-part string (in the form of subId/resGroupName/resName) will be output to stdout.

azchaos resGen mySubId myResGroupName myResName

token

Interactively authenticates the user, and prints the valid accessToken to stdout. This accessToken can be used as the --accessToken <value> in the start and stop commands.

azchaos token
