Development setup

Check the page on how to boot zos in a local setup here. Choose the best one that suits your setup. For development, we would recommend the VM using QEMU.

Using the Python client

Before using the client make sure the ./client/py-client is in your PYTHONPATH. Or pip3 install it like ch client/py-client && pip3 install -e .

from zeroos.core0 import client

# password is only required if zos was booted with `organization=<org>` parameter.
# and in that case, the password must be a valid jwt token from itsyou.online
cl = client.Client(host='<IP address of Docker container running Zero-OS>', password='<JWT>')

#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()
)

Creating a JWT token from itsyou.online.

Login to your profile at https://itsyou.online and from the settings ( gear icon ) create an API key and copy the values.

• Make sure you are have (or memeber of) an organization.

From command line

export CLIENT_ID='<your client id>'
export CLIENT_SECRET='<your secret>'
export ORG=<oranization name>
export VALIDITY_IN_SECONDS=3600
export JWT=`curl -s -X POST "https://itsyou.online/v1/oauth/access_token?grant_type=client_credentials&client_id=${CLIENT_ID}&client_secret=${CLIENT_SECRET}&response_type=id_token&scope=user:memberof:${ORG}&validity=${VALIDITY_IN_SECONDS}"`
echo $JWT

Simply replace the CLIENT_ID and CLIENT_SECRET values with your own.
