server.shell does not support env?

I have this code:

env = dict(EMAIL=host.data.email)
cmd = f"docker stack deploy --compose-file docker-compose.yml {app}"
server.shell(name=f'Deploying stack {app}',
             commands=cmd,
             chdir=app_dir,
             env=env,
             )

but this gives a confusing error:

--> Starting operation: tasks/setup_traefik.py | Deploying stack traefik 
    [testbox.tothemax.nl] env: ‘cd’: No such file or directory
    [testbox.tothemax.nl] Error
--> pyinfra error: No hosts remaining!

Removing env=env makes the error go away (but obviously does not transfer the env vars.)

You are right (of course). Not trusting bash, here is a python equivalent:

from pyinfra.operations import server

server.shell(commands= '''python3 -c "import os; print('The env var is='+os.environ['hello'])"''',
             env={'hello':'world'})

Thanks.

@mjmare this is due to the way bash/shell parses the command; the envvar is being set correctly but the $hello is evaluated beforehand; if you run printenv you’ll see the envvar exists:

from pyinfra.operations import server

server.shell(commands='printenv',
             env={'hello':'world'})

To echo the envvar you need to wrap the command w/sh:

from pyinfra.operations import server

server.shell(commands="sh -c 'echo $hello'",
             env={'hello':'world'})
