How to set Heroku config var with contents of a file
Take a look at the heroku-config
plugin, which adds a heroku config:push
command to push key-value pairs in a file named .env
to the app.
It also has a heroku config:pull
command to do the opposite and works very well with foreman
for running the app locally with the config in .env
.
