# `prefect.infrastructure.provisioners.container_instance`



This module defines the ContainerInstancePushProvisioner class, which is responsible for provisioning
infrastructure using Azure Container Instances for Prefect work pools.

The ContainerInstancePushProvisioner class provides methods for provisioning infrastructure and
interacting with Azure Container Instances.

Classes:
    AzureCLI: A class to handle Azure CLI commands.
    ContainerInstancePushProvisioner: A class for provisioning infrastructure using Azure Container Instances.



## Classes

### `AzureCLI` <sup><a href="https://github.com/PrefectHQ/prefect/blob/main/src/prefect/infrastructure/provisioners/container_instance.py#L46" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>


A class for executing Azure CLI commands and handling their output.

**Args:**
- `console`: A Rich console object for displaying messages.


**Methods:**

#### `run_command` <sup><a href="https://github.com/PrefectHQ/prefect/blob/main/src/prefect/infrastructure/provisioners/container_instance.py#L61" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python
run_command(self, command: str, success_message: Optional[str] = None, failure_message: Optional[str] = None, ignore_if_exists: bool = False, return_json: bool = False) -> str | dict[str, Any] | None
```

Runs an Azure CLI command and processes the output.

**Args:**
- `command`: The Azure CLI command to execute.
- `success_message`: Message to print on success.
- `failure_message`: Message to print on failure.
- `ignore_if_exists`: Whether to ignore errors if a resource already exists.
- `return_json`: Whether to return the output as JSON.

**Returns:**
- A tuple with two elements:
- str: Status, either 'created', 'exists', or 'error'.
- str or dict or None: The command output or None if an error occurs (depends on return_json).

**Raises:**
- `subprocess.CalledProcessError`: If the command execution fails.
- `json.JSONDecodeError`: If output cannot be decoded as JSON when return_json is True.


### `ContainerInstancePushProvisioner` <sup><a href="https://github.com/PrefectHQ/prefect/blob/main/src/prefect/infrastructure/provisioners/container_instance.py#L129" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>


A class responsible for provisioning Azure resources and setting up a push work pool.


**Methods:**

#### `console` <sup><a href="https://github.com/PrefectHQ/prefect/blob/main/src/prefect/infrastructure/provisioners/container_instance.py#L167" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python
console(self) -> Console
```

#### `console` <sup><a href="https://github.com/PrefectHQ/prefect/blob/main/src/prefect/infrastructure/provisioners/container_instance.py#L171" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python
console(self, value: Console) -> None
```

#### `provision` <sup><a href="https://github.com/PrefectHQ/prefect/blob/main/src/prefect/infrastructure/provisioners/container_instance.py#L860" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python
provision(self, work_pool_name: str, base_job_template: Dict[str, Any], client: Optional['PrefectClient'] = None) -> Dict[str, Any]
```

Orchestrates the provisioning of Azure resources and setup for the push work pool.

**Args:**
- `work_pool_name`: The name of the work pool.
- `base_job_template`: The base template for job creation.
- `client`: An instance of PrefectClient. If None, it will be injected.

**Returns:**
- Dict[str, Any]: The updated job template with necessary references and configurations.

**Raises:**
- `RuntimeError`: If client injection fails or the Azure CLI command execution fails.


#### `set_location` <sup><a href="https://github.com/PrefectHQ/prefect/blob/main/src/prefect/infrastructure/provisioners/container_instance.py#L174" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python
set_location(self) -> None
```

Set the Azure resource deployment location to the default or 'eastus' on failure.

**Raises:**
- `RuntimeError`: If unable to execute the Azure CLI command.
