## Development

Python 3.11+ is required.

Install [poetry](https://python-poetry.org/), clone this repository and run:

```
poetry install --with dev --with docs
```

## Build Debian package

Install Docker first, then run:

```
make build-deb
```

`compute` and `compute-doc` packages will built. See packaging/build directory.

## Installation

See [Installation](https://nixhacks.net/hstack/compute/master/installation.html).

## Basic usage

To get help run:

```
compute --help
```

See [CLI docs](https://nixhacks.net/hstack/compute/master/cli/index.html) for more info.

Also you can use `compute` as generic Python library. For example:

```python
import compute

with compute.Session() as session:
    instance = session.get_instance('myinstance')
    if not instance.is_running():
        instance.start()
    else:
        print('instance is already running')
```
