.env file missing

[emanuel.t...@gmail.com]

when I try to access the bbb through the link it gives me error 404 not found when I go to see the nginx logs I find the following error,

*206 open() "/var/www/bigbluebutton-default/.env" failed (2: No such file or directory), client: *, server: +, request: "GET /.env HTTP/1.1", host:

Run the command

docker run --rm --env-file .env bigbluebutton/greenlight:v2 bundle exec rake conf:check

and show this
docker: open .env: no such file or directory.

 Can anyone help me?
