Examples

import nomad
# For HTTP Nomad instances
n = nomad.Nomad(host="172.16.100.10", timeout=5)

# For HTTPS Nomad instances with non-self-signed SSL certificates
n = nomad.Nomad(host="172.16.100.10", secure=True, timeout=5, verify=True)

# For HTTPS Nomad instances with self-signed SSL certificates and no validate the cert
n = nomad.Nomad(host="172.16.100.10", secure=True, timeout=5, verify=False)

# For HTTPS Nomad instances with self-signed SSL certificates that must validate with cert
n = nomad.Nomad(host="172.16.100.10", secure=True, timeout=5, verify=True, cert="/path/to/certfile") # See http://docs.python-requests.org/en/master/user/advanced/#ssl-cert-verification

# For HTTPS Nomad instances with cert file and key
n = nomad.Nomad(host="https://172.16.100.10", secure=True, timeout=5, verify=True, cert=("/path/to/certfile", "/path/to/key")) # See http://docs.python-requests.org/en/master/user/advanced/#ssl-cert-verification

# For HTTPS Nomad instances with namespace and acl token
n = nomad.Nomad(host="172.16.100.10", secure=True, timeout=5, verify=False, namespace='Namespace-example',token='3f4a0fcd-7c42-773c-25db-2d31ba0c05fe')

"example" in n.jobs

j = n.jobs["example"]["ID"]

example_allocation = n.job.get_allocations(j)

n.job.deregister_job(j)

Environment Variables

This library also supports environment variables: NOMAD_ADDR, NOMAD_NAMESPACE, NOMAD_TOKEN, NOMAD_REGION, NOMAD_CLIENT_CERT, and NOMAD_CLIENT_KEY for ease of configuration and unifying with nomad cli tools and other libraries.

NOMAD_ADDR=http://127.0.0.1:4646
NOMAD_NAMESPACE=default
NOMAD_TOKEN=xxxx-xxxx-xxxx-xxxx
NOMAD_REGION=us-east-1a
NOMAD_CLIENT_CERT=/path/to/tls/client.crt
NOMAD_CLIENT_KEY=/path/to/tls/client.key

Development

• create virtualenv and activate
• install requirements-dev.txt
• can either use the Vagrantfile for local integration testing or create environment variables NOMAD_IP and NOMAD_PORT that are assigned to a nomad binary that is running

virtualenv .venv
source .venv/bin/activate
pip install -r requirements-dev.txt

Testing with vagrant and virtualbox

vagrant up --provider virtualbox
py.test --cov=nomad --cov-report=term-missing --runxfail tests/

Testing with nomad binary

./nomad agent -dev -node pynomad1 --acl-enabled
NOMAD_IP=127.0.0.1 NOMAD_VERSION=<SEMNATIC_VERSION> py.test --cov=nomad --cov-report=term-missing --runxfail tests/
