Releases

See the release schedule in the Zero-OS home repository.

Development setup

To run Core0 in a container, just run the following command, which will pull the needed image as well:

docker run --privileged -d --name core -p 6379:6379 g8os/g8os-dev:1.0

To follow the container logs do:

docker logs -f core

Using the Python client

Before using the client make sure the ./pyclient is in your PYTHONPATH.

import client

cl = client.Client(host='ip of docker container running core0')

#validate that core0 is reachable
print(cl.ping())

#then u can do stuff like
print(
    cl.system('ps -eF').get()
)

print(
    cl.system('ip a').get()
)

#client exposes more tools for disk, bridges, and container mgmt
print(
    cl.disk.list()
)
