Common utilities library for Backend.AI

Installation

$ pip install backend.ai-common

For development

$ pip install -U pip setuptools
$ pip install -U -r requirements/dev.txt

Running test suite

$ 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.
