How to pass environment variables to a flyte launchplan that is a cron job?

To pass environment variables to a Flyte launch plan that is a cron job, you can use the

pyflyte run --env

command. This allows you to set environment variables when executing the launch plan. 1. Define the Launch Plan: Create a launch plan with a cron schedule. 2. Set Environment Variables: Use

pyflyte run --env

to pass the environment variables during execution. Example:

from flytekit import LaunchPlan, CronSchedule, task, workflow

@task
def my_task() -> str:
    import os
    return os.getenv("MY_ENV_VAR", "default_value")

@workflow
def my_workflow() -> str:
    return my_task()

cron_lp = LaunchPlan.get_or_create(
    name="my_cron_lp",
    workflow=my_workflow,
    schedule=CronSchedule(schedule="0 */6 * * *"),  # Every 6 hours
)

# Run the launch plan with environment variables
# pyflyte run --env MY_ENV_VAR=my_value my_module.py my_workflow

Thanks, Ketan! I found the solution by setting the env at registration, so it will be respected by the launchplan
