Backend.AI Commons
==================
[](https://pypi.org/project/backend.ai-common/)
[](https://gitter.im/lablup/backend.ai-common)
Common utilities library for Backend.AI
## Installation
```console
$ pip install backend.ai-common
```
## For development
```console
$ pip install -U pip setuptools
$ pip install -U -r requirements/dev.txt
```
### Running test suite
```console
$ python -m pytest
```
With the default halfstack setup, you may need to set the environment variable `BACKEND_ETCD_ADDR`
to specify the non-standard etcd service port (e.g., `localhost:8110`).
The tests for `common.redis` module requires availability of local TCP ports 16379, 16380, 16381,
26379, 26380, and 26381 to launch a temporary Redis sentinel cluster via `docker compose`.
In macOS, they require a local `redis-server` executable to be installed, preferably via `brew`,
because `docker compose` in macOS does not support host-mode networking and Redis *cannot* be
configured to use different self IP addresses to announce to the cluster nodes and clients.
