what is the "foreman way" for behaving differently in production vs development? That is we want foreman start to start up a bunch of stuff in dev, however in heroku production we don't need it to start (for example) solr.
I follow the convention;
Procfile
defines all processes .foreman
set specific foreman variables Development:
.env
sets environment variables for each developer .env.example
sets defaults for development foreman start
starts all processes Production:
heroku config
sets environment variables heroku ps:scale
turns on or off whichever processes are needed for production Here's an example from a project.
Procfile:
web: bundle exec unicorn_rails -p $PORT -c ./config/unicorn.rb
worker: bundle exec rake jobs:work
search: bundle exec rake sunspot:solr:run
.env.example:
# default S3 bucket
S3_KEY=keykeykeykeykeykey
S3_SECRET=secretsecretsecret
S3_BUCKET=myapp-development
.env
# developer's private S3 bucket
S3_KEY=mememememememememe
S3_SECRET=mysecretmysecret
S3_BUCKET=myapp-development
.foreman:
# development port is 3000
port: 3000
Foreman takes arguments to use a different file (-d) and arguments to specify what to run. It also supports a .foreman
file that allows those args to become default. See http://ddollar.github.com/foreman/ for more info
I've used environment-specific Procfile
s before, which is pretty simple and works fine.
Basically you have Procfile.development
, Procfile.production
, etc. In each you can customize the procs you want to start, then run them via foreman
like so:
foreman start -f Procfile.development
Another approach is to reference scripts in your Procfile
, and within each script start up the appropriate process based on the environment. The creator of Foreman does this and has an example from his Anvil project your reference .
Our solution was to use a separate job type in our Procfile for dev vs. production. It is not the most DRY method, but it works...
sidekiq: bundle exec sidekiq
sidekiq-prod: bundle exec sidekiq -e production
Then we run foreman specifying the prod job on the production system:
foreman start -c sidekiq-prod=4
