Passing multiple environment variables a process managed by a supervisor

Question

I need to proxy multiple environment variables from /etc/environment to a process managed by a supervisor.

The following configuration worked for me with supervisor 3.0r1-1 but supervisor 3.2.0-2 reports an error:

environment=FOO=$FOO,BAR=$BAR,BAZ=$BAZ

Error: Unexpected end of key/value pairs in value...

Some answers suggest to quote the values but if I do so, the variables wouldn't be expanded to real values.

What am I doing wrong? How to fix it?

environment=A="1",B="2"

(that is, = is used for both environment itself and for the key-value pairs, separated by commas, with the values bounded with quotation marks)

Also, where does $FOO come from? http://supervisord.org/subprocess.html#subprocess-environment says 'No shell is executed by supervisord when it runs a subprocess' so its not clear how you expect $FOO to work.

`$FOO` is an environment variable. – Kolyunya May 29 '17 at 20:59
From where though? Supervisord isn't passing that to a shell, so its not going to know how to handle it other than as a string. – Jason Martin May 29 '17 at 21:00

`Subprocesses will inherit the environment of the shell used to start the supervisord program.` `$FOO` is an environment variable of the shell used to start the `supervisord` program. – Kolyunya May 29 '17 at 21:00

I defined those variables in `/etc/environment`. – Kolyunya May 29 '17 at 21:04
@Kolyunya so did it, why it's not reading these variables ? – Ricky Levi May 23 '23 at 08:34
