pyvospace¶
VOSpace implementation in Python3.
Requirements
- Python3.6 or greater.
- Docker Support.
- FUSE filesystem modules (including fusepy)
Quick Start Guide
Quick start guide to building and running a posix backed vospace.
From the root of the repository, create and start database environment:
cd pyvospace/server/deploy
docker-compose build
docker-compose up
Create Virtual Environment:
python3 -m venv venv
source venv/bin/activate
From the root of the repository, install pyvospace modules:
pip install -U pip setuptools wheel
pip install .
Create basic configuration:
[Space]
host = localhost
port = 8080
name = posix
uri = icrar.org
dsn = postgres://vos_user:vos_user@localhost:5435/vospace
parameters = {}
secret_key = ZlmNyXdQgRhhrC2Wwy-gLZj7Wv6ZtoKH
domain =
use_ssl = 0
[Storage]
name = posix
host = localhost
port = 8081
parameters = {"root_dir": "/tmp/posix/storage/", "staging_dir": "/tmp/posix/staging/"}
use_ssl = 0
Confirm deployment:
python -m unittest discover test
All the tests should pass. Note: Ignore any ConnectionResetError warnings as it’s part of a test.
Start vospace metadata server:
posix_space --cfg test_vo.ini
Start vospace posix storage server:
posix_storage --cfg test_vo.ini
Install appropriate FUSE libraries for your platform, then install fusepy:
pip install fusepy
Start FUSE posix client:
mkdir /tmp/fuse
python -m pyvospace.client.fuse --host localhost --port 8080 --username test --password test --mountpoint /tmp/fuse/``
Test FUSE posix client:
cd /tmp/fuse
mkdir newdir
cd newdir
echo 'hello' >> data
cat data
