Illegal seek | KeyError: 'SUPERVISOR_SERVER_URL' about supervisor_checks HOT 2 OPEN

Ran into the same problem. Not sure about the root cause, but as a workaround I set the missing environment variable to the unix socket supervisor is configured to listen to.

I.e. add SUPERVISOR_SERVER_URL=unix://local_path, where local_path is the location of the unix socket specified in /etc/supervisord.conf like this:

[unix_http_server]
file=/var/run/supervisor/supervisor.sock   ; (the path to the socket file)

Edit: default URL seems to be http://localhost:9001

@tyler71 @alxgrk How do I reproduce this? What supervisord version you're using? Ideally, if there's a docker image that produces the error, can you send me a link and I will try it.
