crabbox azure groups Azure provider setup commands. It currently has a single subcommand, azure login, which captures your Azure subscription details into the user config so direct-mode Azure leases work without exporting AZURE_* environment variables on every invocation.

#azure login

crabbox azure login detects the active Azure subscription from the local az CLI, validates that credentials can acquire a management-plane token, and stores the subscription, tenant, and location in the user config.

#Prerequisites

  1. Install the Azure CLI (az must be on your

    2. PATH).

  2. Run az login and select the subscription you want Crabbox to use.

#Usage

# Use the active az CLI subscription and the default location (eastus):
crabbox azure login

# Pick a specific subscription by ID or name:
crabbox azure login --subscription 00000000-0000-0000-0000-000000000000

# Pick a specific location:
crabbox azure login --location westus2

# Emit JSON for scripting:
crabbox azure login --json

After login succeeds, crabbox warmup --provider azure and crabbox run --provider azure -- <command> work immediately.

#Flags

--subscription <id|name>    Azure subscription ID or name (default: active az CLI subscription)
--location <location>       Azure location for provisioning (default: eastus)
--json                      Print JSON output

#What it does

  1. Runs az account show (with --subscription when you pass --subscription)

    2. to read the subscription ID, tenant ID, and subscription name.

  2. Validates that DefaultAzureCredential can acquire a token for the Azure

    3. Resource Manager scope (https://management.azure.com/.default). If this fails, run az login and retry.

  3. Writes azure.subscriptionId, azure.tenantId, and azure.location to the

    4. writable user config file (for example ~/.config/crabbox/config.yaml).

  4. Sets provider: azure only when no default provider is already configured.

JSON output (--json) includes subscription, tenant, name, location, and configPath.

#Auto-resolve without azure login

Running crabbox azure login is the recommended way to persist configuration, but it is not strictly required. When a direct Azure command starts and no subscription is set in config or the environment, Crabbox falls back to az account show at runtime to detect the subscription (and tenant). This lets az login plus crabbox warmup --provider azure work with zero extra setup. A location is still required: set azure.location, pass --location, or export CRABBOX_AZURE_LOCATION.

#Credentials and environment

azure login only stores subscription, tenant, and location — it never stores secrets. At provision time Crabbox authenticates with DefaultAzureCredential, or with a client-secret credential when azure.tenantId, azure.clientId, and the AZURE_CLIENT_SECRET environment variable are all present.

Equivalent values can also come from the environment instead of config: CRABBOX_AZURE_SUBSCRIPTION_ID (or AZURE_SUBSCRIPTION_ID), CRABBOX_AZURE_TENANT_ID (or AZURE_TENANT_ID), CRABBOX_AZURE_CLIENT_ID (or AZURE_CLIENT_ID), and CRABBOX_AZURE_LOCATION.
