59# chief
Chief is a port of [foreman] to Racket. It runs sets of processes
together based on a `Procfile`.
## Getting Started
You can install `chief` from the package server by running:
$ raco pkg install chief
## Usage
Create a `Procfile`:
```procfile
assets: npm start
web: raco koyo serve
redis: redis-server --port $PORT
```
Run the processes:
$ raco chief start
Chief will automatically load environment variables from a `.env` file
located in the current directory. Additional `.env` files can be
specified using the `-e` flag:
$ raco chief start -e env-file-1 -e env-file-2
Different procfiles can be specified using the `-f` flag:
$ raco chief start -f Procfile.dev
You can run arbitrarily many processes of each type using the `-m`
flag:
$ raco chief start -m web=1 -m redis=3
Every process type is assigned a range of 100 ports, beginning with
port `5000`, and every instance of a process type gets assigned one of
those ports via the `PORT` environment variable. In the example
above, the `assets` proces would have its `PORT` environment variable
set to `5000`, the `web` process would have its `PORT` set to `5100`,
and the `redis` processes would have their `PORT`s set to `5200`,
`5201` and `5202`, respectively.
## Differences from `foreman`
* The `export` command is not supported.
* The `-e` flag can be passed multiple times.
* The `-m` flag can be passed multiple times.
