Passing Environment Variables to Workload at Launch

This example demonstrates how to pass environment variables to a workload at launch.

Requirements

  • A running Orion instance
  • Orion API Key
  • kuiper role assigned to the user running the script

Script

Warning

If you get a requests.exceptions.SSLError you can pass in the verify=False parameter to the request to disable SSL verification.

Custom environment variables passed at launch 

import os
import requests

server = os.environ["SERVER"]
token = os.environ["TOKEN"]
custom_var = os.environ["CUSTOM_VAR"]
user = os.environ["USER"]
idx = os.environ["IDX"]

# Create a new workload
rsp = requests.post(
    f"{server}/kuiper/request",
    headers={"Authorization": token},
    json={"instance_type": idx, "user": user, "env": {"CUSTOM_VAR": custom_var}},
    verify=False,
)


$ export TOKEN="your-token"
$ export SERVER="https://orion-install"
$ export IDX="go"
$ export CUSTOM_VAR="Hello, World!"
$ export USER="my-user"
$ python custom_var.py

---> 100%

This script will create a workload with a custom environment variable CUSTOM_VAR set to Hello, World!.

Verification

We can verify this by running env inside of a workload terminal.

$ env | grep CUSTOM_VAR
CUSTOM_VAR=Hello, World!
